Will more jobs will be gained than lost by transitioning the country away from fossil fuels?
Will more jobs will be gained than lost by transitioning the country away from fossil fuels and toward cleaner, renewable energy sources?
Some say this is America’s key to remaining number one, yet most Conservatives do not agree and continue to push oil as the number one source. Is it time to drastically change America’s thirst for oil?
No one is listening to Cons anyway. They are still stuck in the 19th century and everybody knows our dependance on oil is a national security issue and that for America to remain the dominate power in the world we had better get with the program and get off of our dependance on fossil fuels. Democrats now have the opportunity to pass legislation to do just that and I hope they act swiftly upon it, else China and others will soon pass us as number one. They are rapidly working on their own green energy and our probably ahead of us already!
What type of engineers work in the field of sustainable energy?
Im considering doing a Building Services and Sustainable Engineering degree, what kind of jobs do you think it will open up for me?
Will i be able to work with sustainable/renewable energies, such as solar panels, wind turbines etc? or would i need a different type of engineering course to do that?
Any more information on engineering would be more than helpfull, im not 100% sure whether i want to do an engineering degree or not.
From my own knowledge, jobs open for Sustainable Engineering degree are Electrical Engineer, Project Engineer, Project Admin., Project Manager etc.
Some consultancies provide solar installation courses, but I am not sure if it is what you want to do.
And sustainable engineering is a vast concept, you may need to choose your major orientation later, like wind energy, bioenergy, or solar…

zero carbon interview questions wanted
I want to write an article on zero carbon homes in the UK, whether the government target of 2016 will be met or not. I intend to interview professionals in the building and construction industry. I am currently arranging an appointment with RIBA environmental president and the current president.. However, my journalism skills are very weak at the moment. I was wondering whether if someone can give me any idea on questions to ask.
I have ideas as in their views on the scheme, what they intend to do to meet the target etc. but I need more questions. Also can someone tell me where I can find information on the German Passivhaus scheme. As in how they set the target, and how they met it etc.
Your help will be much appreciated.
U may look here for all tht u need regarding zero carbon homes:
all questions tht u want for zero carbon homes are here:
The energy efficient German / Austrian PassivHaus standard is recognised by the Code for Sustainable Homes (CSH) as one design approach for dwellings that goes some considerable way towards the government’s ‘Zero Carbon’ target, as TRADA’s new Construction Briefing explains.
The PassivHaus standard is considered by the Department of Communities and Local Government (CLG) to be broadly equivalent to Code Level 4 in the CSH. It recognises that the principles underlying the PassivHaus approach have been driven by the simple desire to drastically reduce the demand for energy in buildings, yet they also achieve an enviable build quality that UK designers and housebuilders might well wish to study.
The following clear targets are set for each dwelling:
The building must not use more than 15kWh/m2/year in heating energy
The specific heat load for the heating source at the desired temperature must be less than 10W/m2
Air leakage levels at 50Pa must not exceed 0.6 times the house volume / hour (approx. 1m3/hr/m2 @ 50Pa)
Total primary energy consumption (heating, hot water and appliance electricity) must not exceed 120kWh/m2/year.
PassivHaus principles cover both new and upgraded buildings and have been broadened beyond dwellings to include educational and commercial buildings. Another major difference between PassivHaus and the CSH is that although the scheme is voluntary, it has grown in popularity particularly because funding mechanisms have been set up to make it commercially attractive to the developer and to give financial support for training to architects and others involved in the build process.
And in true German fashion, the scheme is carefully monitored at every stage. An architect trained in PassivHaus principles and practice designs the dwelling in accordance with all PassivHaus requirements. The design must be successfully appraised using the PHPP (Passive House Development Package). PHPP is a software program similar in concept to SAP2005, designed to consider many aspects of the dwelling’s energy performance at the same time. It seeks to achieve a much higher level of energy performance than that set out in Part L 2006, however, and concerns itself with a wider range of issues.
The PassivHaus Institut (PHI) double-checks the design calculations using PHPP. Products certified by PHI for the external envelope, windows and ventilation systems are then chosen by the architect / client. An air tightness test is carried out at an optimum time in the build process.
The architect is responsible for the Quality Control on site and specific checks must include the following:
Design of heat bridges – using bridge-free connection details or calculating the losses at heat bridges
Design of airtight connection details
Design of all heating, plumbing and electrical systems
Installation of heat free bridges
Installation of insulation layers which are continuous and without air pockets
Installation of joint details and service penetrations for air tightness
Adjustment of ventilation in normal service.
Although there is flexibility in the design of homes and the materials chosen, there are, however, a number of significant constraints in translating the PassivHaus design into a workable scheme for the UK, as the TRADA Construction Briefing explains.
Many within the UK construction industry would agree that we are not building to a sufficient quality to meet even current minimum standards within Part L for energy conservation. The important points about the PassivHaus standard in relation to quality are that:
The actual quality of the building is probably related more to what cannot be seen than by what we can see
The high quality of design and build are not just ‘nice to have’ but fundamentally necessary to achieving the low energy usage
The acid test to for the homeowner will not be whether it looks high quality but whether the quarterly energy bill is near to zero. This test is entirely objective and indisputable!
In short, we would need a very long awaited cultural revolution in design and site practice if we were to adopt the PassivHaus approach, as this would mean embracing the methodical and on-going training, auditing and testing on site which are necessary components of the PassivHaus process.
All ur answers regarding Passivhaus are here:

WHERE DID UNEP FAIL IN ITS STUDY OF GLOBAL WARMING & CLIMATE CHANGE?
UNEP & its scientists then blame transportation & industries as the primary source of pollution. And the world’s defense mechanisms are emission reduction, sustainable development, clean air act, ecological solid waste management act, mitigation & adaptation, etc. But these are subjective beliefs of wishful thinking, not realistic perception & objective reality of how nature works. This is because UNEP & its scientists undermined nature, failing to render better study before & after the treaty was conceived in 1997. Following are scientific grounds which would invalidate the treaty, among others, to wit:
1.Their study did not identify the stages as to how CO2 gas originated. The process of reverse transformation of gas from solid state (biology & physics) is necessary in order to determine the solid matter. Since the world claims that CO2 gas came from fossil fuels, then the origin is plants. To capture pure carbon, the appropriate method is to make natural gases work effectively (via organic matter cycling than carbon reduction).
2.Their study did not consider two classes of organisms. One that takes up CO2 & releases O2 (plants & forests) and the other that takes O2 & releases CO2 (man, animals, birds & sea creatures). If we devoid earth with plants & forests, the other organisms suffer.
3.Their study did not evaluate plants (biology) &/or reactants (chemistry) as possible means to reduce GHG. Concentrating on nature’s secondary process via photosynthesis and chemosynthesis, these will ultimately balance excessive GHG energy as waste gas from all emissions & respirations, conducive for mankind’s primary living.
4.Their study did not identify an abiotic environment which would best suit or gain control to store solid matter (instead of storing in gaseous state) with pure carbon & other carbon compounds (biology, chemistry & physics).
5.Their study did not consider the might of decay microorganisms to send off large volume of CO2 in the atmosphere. Microbes can pollute in billions of CO2 a DAY per gram in solid wastes (like molds growing in spoiled foods), far more than billions (or even trillions) of CO2 a YEAR in tons of burnt coal & oil from transportation & industries since decomposing (or CO2-emitting) microbes are dominant during extreme hot environment (at temperatures between 25-40 degrees Celsius) than beneficial photosynthetic microorganisms (at temperatures between 20-25 degrees Celsius).
6.Their study did not consider that warming has intensified not only due to emissions from transportation & industries but rather due to organic decay from massive desertification of land (losing its capability to photosynthesize).
7.Their study did not consider that if CO2 is higher (claimed at 350 ppm or more), then its leverage with O2 has been impaired, meaning O2 is lower or weaker. In other words, O2 has reached a point of shortage or loss (temporarily) below the standard science record of 20-21%.
8.Their study did not consider O2 as a neutralizer of elements & compounds, taking action with another, being the common denominator of solids, liquids & gases.
9.And finally, their study did not invest on the biological service of CO2 as food and biological necessity of O2 as ingredients to sustain growth & preserve life respectively.
This is a grave & serious fault of UNEP & its scientists, causing faulty analysis & reasoning. The worse of it, IPCC acted as accomplice by introducing its false science too to favor carbon emission reduction and cover up the fraud in science.
Not to be rude.. But have you or anyone else that will read this think about what the world has been doing since the last ice age?? The world has been getting warmer.. The earths temp. Will cycle and continue to do so.. Maybe humans contribute to the effects of the warming.. But the earth will continue to get warmer with or without us.. You would think that the human race would see this and adjust instead of trying to fight something that cannot be changed..who knows maybe overall man has prolonged the global warming effect that we are seeing now.. Or have we increased it??

What are RECs,Renewable Energy Certificates?
We produce green energy and we will get RECs for each 1000 kWh of elec. produced. What are RECs and what are they worth in us dollars?
Renewable Energy Certificates (RECs), also known as Green tags, Renewable Energy Credits, Renewable Electricity Certificates, or Tradable Renewable Certificates (TRCs), are tradable, non-tangible energy commodities in the United States that represent proof that 1 megawatt-hour (MWh) of electricity was generated from an eligible renewable energy resource (renewable electricity). Solar Renewable Energy Certificates (SRECs) are RECs that are specifically generated by solar energy.
These certificates can be sold and traded or bartered, and the owner of the REC can claim to have purchased renewable energy. According to the U.S. Department of Energy’s Green Power Network, RECs represent the environmental attributes of the power produced from renewable energy projects and are sold separate from commodity electricity.
In states that have a REC program, a green energy provider (such as a wind farm) is credited with one REC for every 1,000 kWh or 1 MWh of electricity it produces (for reference, an average residential customer consumes about 800 kWh in a month). A certifying agency gives each REC a unique identification number to make sure it doesn’t get double-counted. The green energy is then fed into the electrical grid (by mandate), and the accompanying REC can then be sold on the open market.
Rices depend on many factors, such as the vintage year the RECs were generated, location of the facility, whether there is a tight supply/demand situation, whether the REC is used for RPS compliance, even the type of power created. Solar renewable energy certificates or SRECs, for example, tend to be more valuable in the 16 states that have set aside a portion of the RPS specifically for solar energy. This differentiation is intended to promote diversity in the renewable energy mix which in an undifferentiated, competitive REC market, favors the economics and scale achieved by wind farms. Current spot prices for SRECs in most states with solar portfolio standards can be viewed at SRECTrade. For example, prices in July, 2010 ranged from $255/SREC in Delaware to as high as $665/SREC in New Jersey.

Would solar panels on the roof of every building solve our energy problems?
I know a few people around here who have used government grants to help install solar panels on their roofs. Given that this is the UK and sunshine is a rare commodity here, they still manage to produce more energy than they use, and actually get a small rebate each year from selling off excess electricity back to the National Grid (our national power infrastructure).
Are there reasons why this can’t be adopted globally? Are solar panels difficult to mass-produce (I imagine they use a few rare-earth elements in there somewhere) or is it just down to a lack of willpower to embrace sustainable energy? How well would the technology scale up from powering individual households to powering energy-hungry manufacturing industries?
I’m not expecting an answer to all those, but I’d like to hear opinions from anyone who might have some knowledge of how it works.
Right now, we don’t have a good large-scale energy storage technology, and we can’t run HGVs or aeroplanes or container ships on solar panels. (at least not the current big heavy ones)
Having a lot of solar panels feeding the grid requires a lot of gas-turbine power stations to make up the difference and respond to rapid fluctuations in demand and supply.
In principle, we might be able to generate hydrogen during the day and use fuel-cells at night, or
run aircraft on liquid hydrogen.
Thinking of changing my major from International Business?
I am currently enrolled in college and am thinking of changing my major from International Business, to Global Marketing or Global Finance. Which major offers better pay, working conditions, etc? . I would like to get into sustainable energy, but I do not think I have the math aptitude for engineering. Which of these degrees is in more demand these days?
I believe International Business is in demand itself but Finance in general is in high demand so long as you’re from a good school or one that’s well-connected.

What are some creative uncommon, creative renewable energy sources?
for my science class exam, I must assemble a portfolio of 4 types of renewable energy technologies, it cannot be solar or wind. I must explain whether the technologies are feasible or not. I must explain the pros & cons of utilizing this type of energy, whether it be environmental, economic, social or political. I can only find wind and solar and we’re not allowed to use those. I know of like cranks and generators but I still need more. So can anyone give me any other good ideas for renewable energy technologies?……….. I have until friday.
A hundred mile long cable attached to a satellite assembled to allow the cable to drag through the Earth’s magnetic field would produces massive amount of energy that could be turned in micro waves, beamed to a receiver on the ground and distributed over the already established grid. A series of small wind turbines arrayed alongside freeways would be turned by the wind energy produced by moving traffic. Using underwater ocean currents to turn turbines is a proven technology and a future use of matter/anti matter interchange is technically feasible as that technology is developed. The best way to improve the energy picture is to use far less of it. We really don’t need all night/every night advertising lights….all that does is burn up massive quantities of fossil fuels for no reason. Of course folks that sell fossil fuels would lose money, and electric companies that sell electricity would lose money as well…but that’s another factor that you might consider bringing up in the discussion.

What would environmentally sustainable transportation look like?
What would environmentally sustainable transportation look like?
Seems like Global Warming might be real. Cars and Planes are two sources of Carbon Emissions that might have a technological solution.
What would an Ecologically Appropriate Transportation System look like?
If, after the Moon Landing in 1969, NASA (or similar gov agency), had spent an equal amount of time, money, and passion to build a clean air transit system; what would it look like?
There’s a lot of ways to have environmentally sustainable transportation. Given our current installed base of gasoline and diesel vehicles, the logical solution would be to synthesize gasoline and diesel from bio-mass waste and utilize the existing distribution networks and existing vehicles. The DoD does this with the Diversified Energy Hydromax gasifier and the Velocys Micro Channel Fischer Tropsche reactor to produce diesel and jet fuel from the waste generated at military installations. This is technology dating back to the 19th century so it doesn’t take a NASA Apollo effort to achieve environmental sustainability (Don’t get me started on the Apollo killing off 1950’s era Project Orion issue). However this does not sell more cars.
Just as with tail fins and the concept of model years, the introduction of new vehicle categories such as the Hybrid, Fuel Cell and before that the SUV, Mini-van, and station wagon lineages prompts the public to replace their vehicles earlier than would be justified on purely utilitarian and environmental considerations. This has driven the economic growth, generous employment and population redistribution that we have seen in the last century and arguably isn’t sustainable.
The question should be is economic sustainability even possible given our current expectations of continued economic growth? Can our expectations be changed? Unfortunately, the free market suffers from the parable of the commons and periodic economic collapse is inevitable in such a system.

Would the person who discovers a way to efficiently power cars using renewable energy become richest person?
Would the person who discovers a way to efficiently power cars just like petrol using endless renewable energy without using fossil fuels and causing pollution become the richest person on earth?
also, is science a job career to take, like physics, biology, chemistry etc? it sounds fun and interesting.
I mean a way to power cars using renewable energy just as efficiently as petrol….electric cars dont really work at the moment imo..
Possibly quite wealthy but telecommunications and computers will always be a more valuable industries than transportation.
So maybe the third richest.
As pornography and robotics have not yet conjoined I still suspect that the person who invents the first realistic sex robot will actually be the richest.
So maybe the fourth richest.

How can UK families become more energy efficient in the future?
are there any ways of becoming more energy efficient for families in the future?
what are the causes of so much energy usage?
what are the effects of it?
I believe neighbourhood communities could be the answer. Families alone find it expensive or impractical to become more energy efficient, however the combined skills, knowledge, capital and resources within a neighbourhood could overcome this.
Utilising a community to transform a neighbourhood can generate so many more benefits. With the use of technology communities could provide their own energy, grow/farm the majority of their own foods, provide social care for the elderly and young. Create infra structure to enable community activities and develop towards being self sustainable.

What can you do with an Associates in Applied Science?
I will be graduating in the Spring of 2013 with an Associates in Applied Science after changing my major from Radiology to Environmental Science/Renewable & Sustainable Energy. My first intent with this degree was to obtain my bachelors. I contacted a few Universities around the country and each made it clear that the gap between a technical renewable degree is quite different from the more engineer-geared bachelors programs. My future has pretty much vanished. Advice? Thanks.
The term “applied science” has come to be used to mean that a particular program is NOT college but rather a vocational certificate. It sounds like you have learned this the hard way. Many schools offer vocational certificates that they refer to as an associates “degree” in applied science. The student is mislead into thinking they are getting a college degree. I hope the school told you that this was not a true college degree.
College level associates degrees are generally just 2 yr. Liberal arts degrees geared towards meeting the gen ed requirements for transfer to a 4 year university. There is a major difference between the college level program and the vocational program you were in. Thus, the vocational credits will not count as college and will not transfer.
The bottom line here is that you have two choices. You can settle for your vocational certificate that was mislabled as a “degree”, or you can pursue a true college degree by taking college level courses. It likely means that you are essentially starting over, this time taking college classes rather than vocational classes. The job prospects and employment outlook is much better for those with a bachelors degree rather than a vocational certificate. This is especially true in the field of environmental science. It sounds like you just made a wrong turn in choosing a non-college program, but you can correct that by switching to college level next semester.
what education/certificates do I need to become a solar pv designer?
I want to be involved with solar pv design or R&D. Getting my msee doesn’t seem possible having a bs in environmental science. Are there any other certificates that I could get that would make me attractive to employers for these sorts of positions? Basically, how can I be involved with the solar industry without being a construction worker, salesman, or having an engineering degree?
There’s a few options for you.
San Juan College in NM has a Renewable Energy program, but there may be a waiting list for it. Http://www.sjc.cc.nm.us/pages/4003.asp “The Renewable Energy Program gives the student a solid foundation in the fundamental design/installation techniques required to work with renewable technologies. The concentration in Photovoltaic System Design and Installation is offered as an A.A.S. Degree and or a one-year certificate.”
Many Community Colleges are starting to offer renewable energy programs, you should check out what may be available near you.
IREC is an organization that certifies schools in renewable energy programs, you can see a list of ISPQ certified schools, including some online courses at: http://www.irecusa.org/index.php?id=91
There are several 1 or 2 week classes that can cover the basics to get you started in the industry without years of school. Some are listed in the IREC link above. The AltE Store has some IREC certified classes in Massachusetts that range from 1 – 5 days. Http://www.altestore.com/classes/

How do i get started in an alternative/sustainable energy (biomass/bioenergy) business/awarness?
I am a current college student (Junior) in Austin, Texas and i am presently study Petroleum engineering but i intend to swtitch to Sustainable energy developement for my Masters program. I need people or someone to partner with or who can help me/us get started. I will like to get started as soon as possible rather than wait untill i graduate? I am very into the alternative energy movement and i need peole like myself to work with. For anyone who just want to help by pitching me random ideas here on yahoo,i will send you $20 dollars via PayPal or else contact me direct to discuss the possibility of working together on the project. I am very open to relacting anywhere that will best suite the chance of success.
With a background in petroleum engineering I’d have thought a good place to start would be with the petro-chemical companies. Many of these are diversifying into alternative and renewable energy sources and as they expand into these areas it would seem likely that they’re going to need people with the relevant skills.
If you can secure a placement with one of these companies and learn something of their core business it would stand you in good stead for a subsequent career opening.
A possibility would be to gain a few years experience with a major company then look at establishing your own business, perhaps with your original employer outsourcing contracts to your new business.
Good luck, hope it all works out for you.

Where can I find information on Hydroelectric Power?
I’m doing a persuasive research paper on why Hydroelectric Power is a better energy resource than any other alternative resources.

Solar is good, but still have the transmission line issues. They are also expensive, but technology is changing to create better panels that produce more voltage per square inch.
Tidal ? Your kidding, right ? First you have to section off a piece of beachfront property just to anchor them out. You’ll need transmission lines to them. Good luck if you live in an area with frequent storms and hurricanes. Beachfront property is the most expensive and beach communities usually don’t like to waste the real estate. The power derived from these are limited so far.
An underwater tidal generator would be a better idea, but its only being experimented with.
Once you look at how much power a city uses, you’ll come to realize that the only way we have to create that power we need in the quantity we need it is Nuclear, coal and / or oil. NOT saying give up on green technologies, but coal plants have come a LONG way and don’t produce the Acid Rain we saw back in the 70’s and 80’s. Especially the new ones and they can utilized carbon sinking systems too. Nuclear is only scarey due to the recent events in Japan, but it has a safe record through history.

What do you think of Sustainable Development? Do you really understand what it is?
It will have a huge impact on your life. I would like to tell you about it but its better if you do the research yourself. Its pretty unbelievable when you think about how the government will control every aspect of our lives.
No, I’m talking about life altering laws that tell you where to live, what you may eat. You will no longer drive and will live in an urban area with many restrictions on your activities. In fact, you will be raising food collectively. I’m talking about major life changes.
I’ve read some on it Bek and every time I do I get a migraine. It’s amazing how much energy these busybodies have. Of course the main ones pushing it don’t plan on living under it. Kinda like Moore and Ted Kennedy and ‘universal healthcare’.. No standing in lines for them..that’s for the peasants.
If individuals want to get together and raise food collectively..hey more power to them. It’s the Central Planning by bureaucrats who live under a separate set of rules that I reject. That’s just putting a happy face on something similar to the old Soviet system. To get this SD plan implemented they’d have to trash what’s left of our constitution…..
Oh never mind..now I get it. )
With reference to climate change and sustainable development what is the futuristic house?
What construction materials are likely to be used and in what architectural styles and what would be the issues involved in their winning, productin and use.
One of these:
HOUSE # 1:
A 20-room mansion (not including 8 bathrooms) heated by natural gas. Add on a pool (and a pool house) and a separate guest house all heated by gas. In ONE MONTH ALONE this mansion consumes more energy than the average American household in an ENTIRE YEAR. The average bill for electricity and natural gas runs over $2,400.00 per month. In natural gas alone (which last time we checked was a fossil fuel), this property consumes more than 20 times the national average for an American home. This house is not in a northern or Midwestern “snow belt,” either. It’s in the South.
HOUSE # 2:
Designed by an architecture professor at a leading national university, this house incorporates every “green” feature current home construction can provide. The house contains only 4,000 square feet (4 bedrooms) and is nestled on arid high prairie in the American southwest. A central closet in the house holds geothermal heat pumps drawing ground water through pipes sunk 300 feet into the ground. The water (usually 67 degrees F.) heats the house in winter and cools it in summer. The system uses no fossil fuels such as oil or natural gas, and it consumes 25% of the electricity required for a conventional heating/cooling system. Rainwater from the roof is collected and funneled into a 25,000 gallon underground cistern. Wastewater from showers, sinks and toilets goes into underground purifying tanks and then into the cistern. The collected water then irrigates the land surrounding the house. Flowers and shrubs native to the area blend the property into the surrounding rural landscape.
HOUSE # 1 (20 room energy guzzling mansion) is outside of Nashville, Tennessee. It is the abode of that renowned environmentalist (and filmmaker) Al Gore.

Who else thinks that all the immaturity and greed among utility companies will serve to promote green energy?
The more big, wealthy gas and oil companies make their services a nuisance with disruptions and price hikes the more the world will turn to alternative supplies of clean, abundant, renewable energy. They are bringing about their own demise with their retarded thinking. Good! Keep it up you shits!
There is no evil per se in the energy business. The problem is, profit and loss alone drives things the way they are, and the environmental costs are, at present. External to the energy companies’ balance sheets, so they have an economic incentive to damage the environment, which historically they have done. Anything that is free gets overused by profit-motivated enterprises, including any environmental resource (air, dump sites, extraction sites, etc.) Utility companies are highly regulated at the State level, and the regulatory bodies are often elected, so the power of the ballot box can be used to get them in line. “Energy companies” (oil, coal, and gas producers) respond primarily to market conditions (collectively, all of us who buy energy) and to regulation (which they fight in the political arena because compliance costs money.)
Energy law must be national or international to be effective, and we, humanity, have barely gotten to the State and Province level for putting these externalities back on the company balance sheets. Furthermore, regulations must be administered by civil servants, so all that elected officials need to do to protect the status quo is to fund too few and appoint managers who are pro-industry.
Green energy will be embraced by the private sector when there is a competitive amount of money to be made in it. In the meantime, individuals can promote legislation that makes the externalities internal, so that green is more profitable, and can take advantage of existing rules that allow homeowners to generate their own power and requires utility companies to buy it.
Demonizing the opposition does not facilitate a solution. In the end, it is what is done, not what is intended, that matters.
Why should we have renewable energy sources?
I am writing an essay and I need the answer to this question I want to write about it but I want to know the reason why we need renewable energy sources so I can state it in my essay.
Renewable energy are the demand of this age. In past, energy were derived from burning of wood and other biomass sources. And then from coal, natural gas and petroleum products. But as these source of energy unlike wood and biomass products require hundreds and thousands of year to produce, they cannot be replenished and their source is getting depleted at faster rate with rise in population. Thus, energy crisis in future can be predicted even when the world is getting more and more energy dependent if we continue to rely only on the these sources of energy.
Another point is, not every country has got crude oil and coal reserves. Their economy is dependent on other countries as their energy cost can be huge which the other country can manipulate, much like middle east controlling oil – supply and prices which went above $140 per barrel (as of now is above $ 40/barrel). This makes a country less dependent on other country for their energy demand if they can use renewable energy available in their country. Energy from biomass is available everywhere, so is the solar energy(less in high latitude), In the region of higher altitude, wind energy can be harnessed, and energy can be harnessed from ocean, river and other water (larger) bodies and from earth (called Geothermal energy).
Another very important advantage is they are clean source of energy. They don’t cause air pollution either while producing energy from them (like energy from coal) or using them (like using gasoline). With the rise of issue of global warming and cutting out green house gas emission, it becomes more and more increasing important to use them instead of more polluting sources of energy.

What do you think of this story? What would your response to it be?
This story was made in1977.
The Nightmare Life Without Fuel
Americans are so used to limitless energy supplies that they can hardly imagine what life might be like when the fuel really starts to run out. So TIME asked Science Writer Isaac Asimov for his vision of an energy-poor society that might exist at the end of the 20th century. The following portrait, Asimov noted, “need not prove to be accurate. It is a picture of the worst, of waste continuing, of oil running out, of nothing in its place, of world population continuing to rise. But then, that could happen, couldn’t it?”
So it’s 1997, and it’s raining, and you’ll have to walk to work again. The subways are crowded, and any given train breaks down one morning out of five. The buses are gone, and on a day like today the bicycles slosh and slide. Besides, you have only a mile and a half to go, and you have boots, raincoat and rain hat. And it’s not a very cold rain, so why not?
Lucky you have a job in demolition too. It’s steady work.
Slow and dirty, but steady. The fading structures of a decaying city are the great mineral mines and hardware shops of the nation. Break them down and re-use the parts. Coal is too difficult to dig up and transport to give us energy in the amounts we need, nuclear fission is judged to be too dangerous, the technical breakthrough toward nuclear fusion that we hoped for never took place, and solar batteries are too expensive to maintain on the earth’s surface in sufficient quantity.
Anyone older than ten can remember automobiles. They dwindled. At first the price of gasoline climbed—way up. Finally only the well-to-do drove, and that was too clear an indication that they were filthy rich, so any automobile that dared show itself on a city street was overturned and burned. Rationing was introduced to “equalize sacrifice,” but every three months the ration was reduced. The cars just vanished and became part of the metal resource.
There are many advantages, if you want to look for them. Our 1997 newspapers continually point them out. The air is cleaner and there seem to be fewer colds. Against most predictions, the crime rate has dropped. With the police car too expensive (and too easy a target), policemen are back on their beats. More important, the streets are full. Legs are king in the cities of 1997, and people walk everywhere far into the night. Even the parks are full, and there is mutual protection in crowds.
If the weather isn’t too cold, people sit out front. If it is hot, the open air is the only air conditioning they get. And at least the street lights still burn. Indoors, electricity is scarce, and few people can afford to keep lights burning after supper.
As for the winter—well, it is inconvenient to be cold, with most of what furnace fuel is allowed hoarded for the dawn; but sweaters are popular indoor wear and showers are not an everyday luxury. Lukewarm sponge baths will do, and if the air is not always very fragrant in the human vicinity, the automobile fumes are gone.
There is some consolation in the city that it is worse in the suburbs. The suburbs were born with the auto, lived with the auto, and are dying with the auto. One way out for the suburbanites is to form associations that assign turns to the procurement and distribution of food. Pushcarts creak from house to house along the posh suburban roads, and every bad snowstorm is a disaster. It isn’t easy to hoard enough food to last till the roads are open. There is not much in the way of refrigeration except for the snowbanks, and then the dogs must be fought off.
What energy is left cannot be directed into personal comfort. The nation must survive until new energy sources are found, so it is the railroads and subways that are receiving major attention. The railroads must move the coal that is the immediate hope, and the subways can best move the people.
And then, of course, energy must be conserved for agriculture. The great car factories make trucks and farm machinery almost exclusively. We can huddle together when there is a lack of warmth, fan ourselves should there be no cooling breezes, sleep or make love at such times as there is a lack of light—but nothing will for long ameliorate a lack of food. The American population isn’t going up much any more, but the food supply must be kept high even though the prices and difficulty of distribution force each American to eat less. Food is needed for export so that we can pay for some trickle of oil and for other resources.
The rest of the world, of course, is not as lucky as we are.
Some cynics say that it is the knowledge of this that helps keep America from despair. They’re starving out there, because earth’s population has continued to go up. The population on earth is 5.5 billion, and outside the United States and Europe, not more than one in five has enough to eat at any given time.
All the statistics point to a rapidly declining rate of population increase, but that is coming about chiefly through a high infant mortality; the first and most helpless victims of starvation are babies, after their mothers have gone dry. A strong current of American opinion, as reflected in the newspapers (some of which still produce their daily eight pages of bad news), holds that it is just as well. It serves to reduce the population, doesn’t it?
Others point out that it’s more than just starvation. There are those who manage to survive on barely enough to keep the body working, and that proves to be not enough for the brain. It is estimated that there are now nearly 2 billion people in the world who are alive but who are permanently braindamaged by undernutrition, and the number is growing year by year. It has already occurred to some that it would be “realistic” to wipe them out quietly and rid the earth of an encumbering menace. The American newspapers of 1997 do not report that this is actually being done anywhere, but some travelers bring back horror tales.
At least the armies are gone—no one can afford to keep those expensive, energy-gobbling monstrosities. Some soldiers in uniform and with rifles are present in almost every still functioning nation, but only the United States and the Soviet Union can maintain a few tanks, planes and ships—which they dare not move for fear of biting into limited fuel reserves.
Energy continues to decline, and machines must be replaced by human muscle and beasts of burden. People are working longer hours and there is less leisure; but then, with electric lighting restricted, television for only three hours a night, movies three evenings a week, new books few and printed in small editions, what is there to do with leisure? Work, sleep and eating are the great trinity of 1997, and only the first two are guaranteed.
Where will it end? It must end in a return to the days before 1800, to the days before the fossil fuels powered a vast machine industry and technology. It must end in subsistence farming and in a world population reduced by starvation, disease and violence to less than a billion.
And what can we do to prevent all this now?
Now? Almost nothing.
If we had started 20 years ago, that might have been another matter. If we had only started 50 years ago, it would have been easy.
I think it is a very mild projection i would have thought i might be much worse .
The aspects of a global nuclear war or the full effects of Global warming have not been included.
Such as rising seas ,which could displace millions of people ,moving them further in land ,to fight it out with the residents already there causing wide spread public violence.
Also global food and potable water shortage ,and we have since come up with many alternatives to producing power ,why did he leave out solar or wind power.
But then this story was from 1977,and even so Asimov is a master at imagining future happenings
I wonder what he would see today ,it will be a different story.
The solution to a world devoid of energy is to think backwards and improve upon it .This is what Permaculture is all about sustainable ideas from the past (only in the past can prove of sustainability be found )
So my response is teach the people about PERMACULTURE a way of life using ingenuity and innovation with limited technology or dependence on Government energy sources,derived from a collection of sustainable ideas from around the world coupled to present level of knowledge
ideally suited for those who want to get back to the country and build a auto sufficient situation for themselves and the family or a community .
People plant rather for the quality of life and to feed their families, than for the market ,so the motivation and the manner are totally different from ordinary agriculture .
Although the basic concept of Permaculture also applies to Organic and sustainable farming,
Utilizing soil management ,and mulching
The utilization of space is more concentrated ,thinking in cubic and vertical terms instead or merely horizontal on the plain ,
Having many principle to follow such as utilizing all resources and following and enhancing energy flows ,
for example the ditch around the house catches the rain water and leads it through the chicken house where it cleans and picks up the manure to deposit it in the vegetable patch
Permaculture means permanent agriculture
a concept put forward by Bill Mollison in the 60`s
Which offers practical solutions for energy systems ,infrastructure ,intelligent design in housing,
animal shelter ,water systems and sustainable agricultural practices.
With the world and it`s history as it`s source
From the chinampas of Mexico to the terraced gardens of the Andes.
From the dessert wadis to the steppes of Russia.
Covering all climatic conditions temporal, dessert, humid and dry tropics.
With chapters on soil ,Water harvesting and land design,Bio diversity
Earth working ,Spirals in nature,Trees and water ,utilizing energy flows,
Strategy for an alternative nation
including gardening tips,bio-gas,companion planting and ideas for structures ,how to cool down houses in hot climates ,how to warm up houses in cold climates with out using technology but rather by design.

Power Wastage Question?
If you leave a power charger in the power socket and have the switch switched on, will it waste power even though nothing’s plugged in at the other end?
For example, you have a phone charger cord plugged in and switched on, but no phone is attached, is power wasted?
No… i don’t think you understand. There is no electrical device plugged in. Just a cord
the charger doesn’t get hot
Almost every electronic device uses some electricity just by being plugged in. In fact, phone chargers often come up in articles about saving energy and such.
David MacKay, a professor at the University of Cambridge, to the rescue. Dr. MacKay has published an online tome “Sustainable Energy – Without the Hot Air” (free PDF download here) which relies on Kilowatt-Hours to quantify these decisions. It’s incredibly comprehensive – 409 pages – and provides the apples-to-apples that points you in the right direction.
Case in point – cell phone chargers. David performs some tests and concludes that these chargers use maybe 0.01-0.05 kWh per day; over a year, that’s the equivalent of a skipping a single bath (5 kWh per pop), or driving 6 minutes less annually (average driver being 40 kWh per day). David makes the point that all else being equal, you should of course unplug the charger. On balance though, better to go stinky for one day or lose a convenience store run. :: Without Hot Air

What is the difference between conservation and recycling?
All resources are finite inclusive of renewable resources in the larger meaning of conservation of mass and energy.
Hi, Conservation and Recycling are a similar and different.
The easy definition of Conservation is just the “wise use” of any resource such as timber, water, farmland, wildlife, or just about any renewable and non-renewable resources.
Recyling, on the other hand, is putting something to use, that has already had one useful purpose and is nolonger needed for its original intended purpose. Examples are the recycling of aluminum cans, doors, folding chair and window frames.
The difference you asked for is that Conservation may be an overall term that covers just about use you make of the environement, while Recycling is use one aspect of conserving our resources.
Good Question: Both are great concepts and highly important, even essential, in good environmental stewardship.
What makes a resource renewable or nonrenewable?
What are examples of renewable and nonrenewable resource?
A resource that will never be depleted by using it up is renewable.
Wind hydro, trees, farm crops appear to be renewable.
Things we get out of mine or well, other than water, are non-renewable.
Fresh water is an important resource that appears to always regenerate itself. But fresh water right here is not quite as renewable. Some times we do run out of fresh water here even when there is a major flood of it somewhere else.
Geothermal energy is often wrongly classified as renewable. The amount of available geothermal energy may be very large, but it is finite.
Solar energy is renewable within the lifetime of earth even if the sun may be snuffed out. Its being snuffed out is not a result of our overuse.
Wind is classified as renewable even though it runs out, because it is not running out from use, and wait a few months and the wind will blow again.
While farm crops may be a renewable resource they depend on non-renewable resources, the minerals plants need come from the soil or are mined, manufactured. So, we can run out of those nutrients. Or put another way, the nutrients can be allowed to escape to the oceans. We can even run out of soil itself as it erodes and flows to the oceans.
When a resource is dependent on non-renewable resources we might treat that as a non-renewable. But classic definitions do regard plants and geothermal as renewable.

What business can i start in south india with Rs.1 lakh?
I’m a mechatronics engineering graduate who wishes to start my own business venture in india. I am willing to invest Rs.1,00,000-1,50,000. I wish to get a profit of Rs.50-70,000 per month within 2-3months after starting the business. Is it possible to start a renewable energy based company on these terms? I am ready to put in a lot of hard work. I hope to get some genuine suggestions from everyone here. Thanks in advance
Starting a business is big step is life and it is even bigger than marriage decision especially when you are new to this!
You may get many genuine advice. But tell me one thing, if everyone could do business just like you mentioned with 1 Lakh ( let us consider 10 Lakh) and get monthly profile of 50K then no one would be answering here. Everyone could be happy to work hard to get more profit 🙂
Be realistic about business. Do not play with numbers. Play with ideas.
Bottom line : Answer to your question – There are many small ventures working in energy sector. One of my friend work in solar energy sector in Bangalore. It took him almost 2 years to build network and get customers. Atleast for one year he was running business in loss.
Remember, its a venture, full of adventures. If you can handle it, think about it. Without profit business wont work and without planning nothing works. Meet experts, get into start-up group.
why are environmentalists voting no on CA prop 7?
i’ve read that groups like the sierra club and the environment defense fund oppose prop 7. i don’t understand — doesn’t it increase renewable energy? what’s wrong with this bill?
i support environmental causes but i want to know what the facts are before tuesday. any insight would be appreciated.
What it does is insist that ONLY huge companies can provide clean energy, which will put out of business all the little companies that have been developing and implementing clean energy all this time.
It also sets inflated energy rates, costing everyone MORE for cheaper energy.
I bet League of Women Voters has good stuff on this.
You could also go to NRDC and Sierra Club web sites; I bet they lay our their reasoning there.

What is a voltage inverter and converter?
please can you tell me what they are…i am doing this for my design tech project sustainable energy A level
An Inverter is a device which inputs battery level DC (usually 12V, large scale systems may be 24 or 48 volts) and outputs domestic mains voltage/current. Cheap ones output a coarsely simulated AC, better ones provide a wave which more closely resembles sinusoidal AC.
A converter, generally, is a device which changes the input of the device to a different output.
In power, it usually means voltage, which may be a transformer for AC power, or a switch mode converter for DC.
Can a UK Government (Labour or Tory) really invest in creating green jobs and pulling us out of recession?
Or will the money get spent on expensive weapons systems instead?
The Atlantic weather front breaks on this country. If Europe has successful wind energy programs then why can’t we. 40% of the net wind energy throughout Europe is in the UK.
We’re also surrounded by the sea which means we have massive potential for wave energy devices and tidal turbines but, this technology is less developed than wind energy.
Then we are also not utilising our own rubbish enough. We are running out of landfill and are burying a great potential energy source. Incineration, although not everyone favourite can generate vast amounts of electricity.
Then there’s cows. We have a very sustainable farming industry (providing the government is there to support it). Using anaerobic digesters we can produce quite a bit of energy also.
There are many materials out there that can make our homes more efficient. Further research and the backing to get companies off the ground to produce these materials can make huge savings in energy usage.
There are many potential methods to really kick start a green economy it just needs a government to get behind the idea and crack on with it.

Why is important for business to use renewable energy?
Why is important for ‘business’ to use renewable energy? What are the advantages and disadvantages? Do you know a company that uses renewable energy and has reduced its carbon footprint? And one that doesn’t and is considerably contributing to global warming etc
It’s important because fossil fuels are a finite resource. Global oil production is beginning to decline as old oil fields reach their peak, (the Gwhar and Cantrell giant oil fields for example,) and their production curves begin the inevitable slide downwards. Although new oil fields are being discovered, they are not very large, and for every new barrel of oil found, eight are being used at the same time.
A report from the UK Energy Research Centre published in August said that there was a ‘significant risk’ that the peak of conventional oil production would happen before 2020, and that means we will soon be staring down the barrel of the ultimate oil crisis.
Some governments and corporations are waking up to this and beginning to develop alternatives to keep the worlds transport systems moving when cheap oil runs out, such as more energy efficient – or electric cars, bio fuels (which put the world’s food supply under pressure,) and hydrogen (which is too dangerous for public use at present,) but none of these is likely to make up the shortfall in time.
Many point to the tar sands and oil shales and the trillions of barrels of oil that are locked up in them, but even if investment in them poured in and everything went well:
‘oil sands might produce 6 million barrels of oil per day in 20 years’ time, but by then we’ll need to add at least 10 times that much capacity – without allowing for any growth in demand. It’s very hard to see non-conventional (oil sources) riding to the rescue.’ (Steven Sorrel, lead author of the UKERC report.)
There is also the problem that extracting non conventional oil supplies is very environmentally destructive, and if they were fully exploited, would hugely increase CO2 emissions, before they were even burned as fuel.
We must also remember that many of the rare earth metals that are needed to develop fuel efficient technologies are only found in China, and they have decided to limit or even ban the export of these metals, leaving all the other countries that wish to expand their use of such technologies at a disadvantage.
So the only businesses that can secure energy supplies are those that invest in renewable energies now, before the oil price rises, (due to demand outstripping supply,) and before the costs of making such renewables rises too as a result of resource depletion and the constrained supply of raw materials.
What would be the advantage to the USA of a thriving, high tech Renewable Energy Industry?
China’s investing in production and implementation of Renewable Energy, and is a big player in solar panel manufacture and installations, so is Japan, Germany, Spain. Why not the USA?
It is generally accepted that we can prevent earth’s deterioration if we achieve a renewable energy world. When we hear the word renewable energy we normally think of state-of-the art equipments and high-end technology. But, we can start today. Simple acts can help jumpstart the initiative of saving our planet.
Because renewable energy sources like solar and wind do not require the use of fossil fuels, they do not emit carbon dioxide. Carbon dioxide is a bi-product of burning coal and gas. By reducing the amount of fossil fuels we burn, we are decreasing the amount of pollutants and chemicals being emitted into the atmosphere.
Pollution coming from power plants taints our air supply and causes asthma. Through the use of renewable energy, we could eliminate these harmful substances in the air, leading to a healthier population.
Once the solar panels are installed and the windmills are put up, renewable energy is essentially free. It costs nothing to use the suns rays, and taking advantage of a windy day is free. Furthermore, the supply of wind is not going to diminish. The sun’s rays are also prevalent and will exist for millions of years.

What are the best three electrical energy suppliers?
[Location no object] Can anyone give me the details of three electrical energy suppliers that offer the best value for money?
And any additional details about the company…(Website etc…)
Solar energy is the radiant light and heat from the Sun that has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation along with secondary solar resources such as wind and wave power, hydroelectricity and biomass account for most of the available renewable energy on Earth. Only a minuscule fraction of the available solar energy is used.
Solar power technologies provide electrical generation by means of heat engines or photovoltaics. Once converted its uses are only limited by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, daylighting, hot water, thermal energy for cooking, and high temperature process heat for industrial purposes.
Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute sunlight. Active solar techniques include the use of photovoltaic panels, solar thermal collectors, with electrical or mechanical equipment, to convert sunlight into useful outputs. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.
Wind power is the conversion of wind energy into a useful form, such as electricity, using wind turbines. At the end of 2008, worldwide nameplate capacity of wind-powered generators was 120.8 gigawatts. Although wind produces only about 1.5% of worldwide electricity use, it is growing rapidly, having doubled in the three years between 2005 and 2008. In several countries it has achieved relatively high levels of penetration, accounting for approximately 19% of electricity production in Denmark, 10% in Spain and Portugal, and 7% in Germany and the Republic of Ireland in 2008.
and Waves,(as in ocean waves)
Ocean waves are caused by the wind as it blows across the sea. Waves are a powerful source of energy.
The problem is that it’s not easy to harness this energy and convert it into electricity in large amounts. Thus, wave power stations are rare.
Today the largest use of hydropower is for the creation of hydroelectricity, which allows low cost energy to be used at long distances from the water source. Hydroelectricity is electricity generated by hydropower, i.e., the production of power through use of the gravitational force of falling or flowing water. It is the most widely used form of renewable energy. Once a hydroelectric complex is constructed, the project produces no direct waste, and has a considerably different output level of the greenhouse gas carbon dioxide (CO2) than fossil fuel powered energy plants. Worldwide, hydroelectricity supplied an estimated 715,000 MWe in 2005. This was approximately 19% of the world’s electricity (up from 16% in 2003), and accounted for over 63% of electricity from renewable sources.
Some jurisdictions do not consider large hydro projects to be a sustainable energy source, due to the human, economic and environmental impacts of dam construction and maintenance.
What is the relationship of resources and development?
Nepal is rich in natural resources like land, water, and biodiversity. Nepal should have developed through energy generation from rivers, tourism from aesthetic and panoramic view of mountains, hills, flat plains, green forests. Similarly, medicine and other products are possible from diverse flora and fauna. But it is not developed. Aren’t there any linkages on resources and development?
Yes, there is generally a positive relation between natural resource andowment and economic development. But this relationship holds strongly true in an environment of free movement of capital and labor and generally competitive free market system. In the absence of an autmatic and sustainable system that makes best use of the available resources, economic development cannot come about.
But Nepal, although being a small country, never had a free competitive market system. Rather, it remained feudalistc with the King and elected ministers copying Indian centrally planned system of State controls and direction and domination. Such systems talk loudly about best use of resources, high economic growth and equity but they are seldom efficient or effective in delivering the tall promises the politicians sell to the public: rather these kinds of systems are the best suited for the rapid growth of corruption and injustice together with huge misallocation of resources. On top of the low education makes productivity low. Political and economic oppression leads to frstrations and breeds insurgencyaided by foreign forces. These do not foster economic developmenrty. Education, competetive markets, desire to excel, allowing globally efficient companies to set up businesses without hindrances are all required for economic development. Nepal also has shown hatred and disrect to India, despite enjoying huge facilities from India. Such blindness has placed Nepal at a great disadvantage
It is ultimately the quality of the human resources in terms education, willingness to work harder, adopting congenial value system are the keys to taking best advantage of the natural resouirces.
