Your Questions About Sustainable Energy Companies

Donna asks…

how to look ahead to a sustainable future?

What is going on with a sustainable future? What are the problems associated with this and what can be done to solve it? What are real world examples?

admin answers:

Basically a sustainable future would be one in which the majority of resources and energy sources we utilize are renewable, coupled with disposing wisely of waste (and reducing the amount of waste made in the first place), managing land responsibly and eliminating air, water and soil pollution. Renewable forms of energy include bio-fuel, solar, wind, hydro, and some would argue things like methane harvesting, hydrogen, and nuclear. This would include phasing out and ultimately getting rid of fossil fuels, which all pollute when “burned” to make energy (admittedly some far less than others) and are finite (i.e. Not renewable; once they are gone, they are gone). The mining/drilling to harvest them has a significant environmental impact as well. Renewable resources would include plant based plastic products & fabrics, fast-growing tree varieties that don’t deplete the soil, utilizing materials that can easily and cheaply be recycled again and again, etc. Better waste management also goes back to recycling and reusing (for instance millions of items are thrown out every year that could be donated to thrift stores, homeless shelters, etc) but also reducing the amount of unnecessary waste by producing products that are more durable, with less packaging that can be recycled when they are no longer able to be repaired.
Problems with achieving more sustainability include the following:
1.Resistance to phasing out fossil fuels – many of the economic and political powers of our time are involved with the fossil fuel industries in some way and are afraid of losing their fortunes. They fight to keep regulations weak and ultimately to work against renewable energy sources being researched, refined and widely implemented. The average American also does not want to pay more for alternative fuel or for a vehicle that will use it, even if the long term savings make up for (increased mpg, longevity, etc). Thus there is not a push on the government or large corporations to research alternative energy or improve mass transit (as it is in Europe).
2.Poor land management – for instance reducing meat consumption would reduce the needed amount of farm animals, reducing the demand on the grain supply. The grain we feed animals for meat would feed thousands of times more people than it does animals. We also need to think about WHAT we plant for renewable resources – for instance using all corn for ethanol and bio-fuels has jacked up the price of corn for countries that use it for food and has severely decreased bio-diversity (having a wide variety of crops), which is very bad for the soil. It has other economic factors as well. We also have to consider the way we farm – are we polluting the soil and rivers with runoff?
3.Laziness and apathy – People don’t want to do anything that takes extra time, money or effort; they don’t want to recycle, read labels, lobby companies and politicians for greener products and policies, pay a little more for organic or for an electric vehicle, etc. People believe the convenient lies some people weave about global warming being a face and pollution not being a “big deal” (or the often heard idea “I’ll be dead when it’s really bad so it doesn’t matter” or “one person can’t make a difference”) because then they don’t feel bad about themselves or their choices.
4.Lack of government initiative to “green” the country, even on a local level – many municipalities, and the state and federal governments as a whole, don’t put the effort into promoting green policies, renewable energy and conservation necessary to fuel real change. In the same way many Americans did not want racial equality but the government passed the Civil Right Act to force it, the government needs to step in and legislate green concerns. The conservative body always decries the government being involved in people’s lives, but frankly many people are selfish and uninformed and won’t “do the right thing” unless forced. We can’t sit back and do nothing about a huge problem just people don’t want to be told what to do like spoiled teenagers. Because the government doesn’t push harder regulations, or offer better incentives, the corporate sector is not willing to invest in utilizing or developing green technology, keeping it expensive and not easily accessible.

James asks…

How could world energy consumption be more evenly distributed?

I know that my family uses alot of extra energy and I think its safe to assume other American families also consume more energy than neccessary. But how exactly will me turning off the lights when I leave give third world countries energy. Also alot of developing countries lack clean water because purifying water requires energy some parts of the world just don’t have, should more developed countries step in, if so how?

admin answers:

>How could world energy consumption be more evenly distributed?

Make the poor areas more prosperous! Stop thinking of energy consumption as a driver, it is a consequence.

>But how exactly will me turning off the lights when I leave give third world countries energy

It would have almost zero effect. But what about if everyone used 10% less power and sent the money that would have gone to the power company to some organization working on providing clean drinking water to third world countries?

>should more developed countries step in, if so how?

They have! Particularly the US has spent a lot of money over a long period of time. With very little to show for it.

The problem is it is extremely difficult to “give” prosperity to someone in the long run. This is true of both individuals and countries. This seems to be human nature.

The key seems to be changing the culture/mindset of the recipients to make improvements sustainable. But doing so is not only difficult, it’s politically incorrect.

Your Questions About Renewable Energy For Kids

Helen asks…

Why do people think that renewable energy is not viable or economical?

Think about how much it costs to pull stuff out of the ground, refine it and ship it all over the world? How about wind, solar, geothermal, tidal etc?
I am not saying don’t have oil for back up. I am saying it shouldn’t be used first and only.
Elmer going onto websites and acting tough just makes you look like a sissy.
Dez Pirate that is a great answer. Thanks.

admin answers:

Probably because of years of big oil propaganda. I know I look a conspiracy theory nut saying this, but just look at some of these answers. Its sad. If they worked better, we would be using them. We aren’t using them, therefore they must not be better?? Are you kidding me? Do you know how much money oil companies spend lobbying not to spend grants on renewable energy research, or other forms of energy in general? Car companies and other industries that rely on fossil fuels like coal, natural gas, etc… Do this as well. They make too much money as it is, of course they dont want change.

We could make a lot of progress on renewable energy sources and ways to package it/store it if our government (and corporations) cared at all about anything more than money. General it they constantly say it isn’t an issue, and that global warming is fake, and that there is no alternative. We are the US for Pete’s sake. If it doesnt exist yet, then we should be making it happen. But no. We are controlled by greedy fat bastards

Jenny asks…

I know fluorescent lighting is more energy efficient but how much energy is it saving?

What if all the fluorescent lights in a classroom were turned off, about how much money or energy would that actually save?

admin answers:

Hey Pink, Jerry is pretty close on the power usage. To answer your question as directly as possible, my son is in 5th grade, and his classroom has three strips of lights, each one made up of five fixtures. Each fixture is 4 feet long and has 2 – 48inch tubes inside. This type of fixture generally uses 72watts with both tubes running. The total wattage for the room is 72 X 15 = 1,080 watts when all the lights are on. Flourescent lighting is about 4 times as efficient as incandescent lighting. To light that same room with old fashioned light bulbs would require over 4000 watts, so the power of flourescent lights is pretty easy to see.

Most schools pay a slightly reduced rate for electrical power, but still the amount varies quite a bit from state to state. In our town, a school should pay around 9 cents per kilowatt hour. A kilowatthour, or KWH is 1000 watts running for one hour. Let’s say the school is open for 8 hours, but the kids are only in the room for 6 of them. If the lights were on for 6 hours, it would use 6.5 KWH, at a cost of about 60 cents. So if the lights were off all day, it would save the school 60 cents each day. If they were only on for 3 hours each day instead of 6, it would save 30 cents each day of school, or about $6.00 per month. Again, this will vary school to school, and town to town, but the idea is the same.

If you’re in the education business, here is something you might be interested in. Look online for a device called a, “Kill – A – Watt,” meter. They cost around $35. They look like a lamp timer, but are really a load meter. Plug it into the wall, then plug any device with a cord you have laying around into the meter. It will tell you how many watts your device is using at the moment, and how many KWH’s it has used over time. Some models even let you punch in your utility rate, and it spits out how much your device has used in dollars and cents for as long as you have it plugged in. Now take a lamp and put in a 40 watt light bulb and run it on the meter, it will tell you it is using 40 watts. Next, change the bulb to a 15 watt compact flourescent one, it will register 15 watts, but ask the kids in the room which one is brighter, turns out they are about the same. It’s really interesting to see the lights literally come on in the room when you do experiments like this.

We live in a home that is powered by the wind and sun, and over time we’ve had to learn a great deal about energy savings. From time to time, we get to run a solar power seminar for the kids in the schools in our area, and this is one of the experiments we do. It’s also interesting to plug other items into the meter, like a radio, or a game system, so the kids can see how much they are using at home. There is a great magazine out that covers all this stuff, it’s not very common on news racks, it’s called Home Power. I will include the link below, and some other places you can google to find out lots of interesting info on renewable energy and energy savings. Take care Pink, Rudydoo

Alternative Energy Development in Japan

Japan is a densely populated country, and that makes the Japanese market more difficult compared with other markets. If we utilize the possibilities of near-shore installations or even offshore installations in the future, that will give us the possibility of continued use of wind energy. If we go offshore, it’s more expensive because the construction of foundations is expensive. But often the wind is stronger offshore, and that can offset the higher costs. We’re getting more and more competitive with our equipment. The price if you measure it per kilowatt-hour produced is going lower, due to the fact that turbines are getting more efficient. So we’re creating increased interest in wind energy. If you compare it to other renewable energy sources, wind is by far the most competitive today. If we’re able to utilize sites close to the sea or at sea with good wind machines, then the price per kilowatt-hour is competitive against other sources of energy, go the words of Svend Sigaard, who happens to be president and CEO of the world’s largest wind turbine maker, Vestas wind systems out of Denmark. Vestas is heavily involved in investments of capital into helping Japan expand its wind turbine power generating capacity. It is seeking to get offshore installations put into place in a nation that it says is ready for the fruits of investment into alternative energy research and development.

The Japanese know that they cannot become subservient to the energy supply dictates of foreign nations World War II taught them that, as the US decimated their oil supply lines and crippled their military machine. They need to produce energy of their own, and they being an isolated island nation with few natural resources that are conducive to energy production as it is defined now are very open to foreign investment and foreign development as well as the prospect of technological innovation that can make them independent. Allowing corporations such as Vestas to get the nation running on more wind-produced energy is a step in the right direction for the Japanese people.

The production of energy through what is known as microhydoelectric power plants has also been catching on in Japan. Japan has a myriad rivers and mountain streams, and these are ideally suited places for the putting up of microhydroelectric power plants, which are defined by the New Energy and Industrial Technology Development Organization as power plants run by water which have a maximum output of 100 kilowatts or less. By comparison, minihydroelectric power plants can put out up to 1000 kilowatts of electrical energy.

In Japan, the small-scaled mini- and micro-hydroelectric power plants have been regarded for a considerable time as being suitable for creating electricity in mountainous regions, but they have through refinement come to be regarded as excellent for Japanese cities as well. Kawasaki City Waterworks, Japan Natural Energy Company, and Tokyo Electric Power Company have all been involved in the development of small-scale hydroelectric power plants within Japanese cities.

Alternative Energy in Ireland

The Irish are currently pursuing energy independence and the further development of their robust economy through the implementation of research and development into alternative energy sources. At the time of this writing, nearly 90% of Ireland’s energy needs are met through importation the highest level of foreign product dependence in the nation’s entire history. This is a very precarious situation to be in, and the need for developing alternative energy sources in Ireland is sharply perceived. Ireland also seeks to conserve and rejuvenate its naturally beautiful environment and to clean up its atmosphere through the implementation of alternative energy supplies. The European Union has mandated a reduction in sulphuric and nitric oxide emissions for all member nations. Green energy is needed to meet these objectives. Hydroelectric power has been utilized in Ireland in some areas since the 1930s and has been very effective however, more of it needs to be installed. Ireland also needs to harness the wave power of the Atlantic Ocean, which on its west coast is a potential energy supply that the nation has in great store.

Ireland actually has the potential to become an energy exporter, rather than a nation so heavily dependent on energy importation. This energy potential resides in Ireland’s substantial wind, ocean wave, and biomass-producing alternative energy potentials. Ireland could become a supplier of ocean wave-produced electricity and biomass-fueled energy to continental Europe and, as they say, make a killing. At the present time, Ireland is most closely focused on reaching the point where it can produce 15% of the nation’s electricity through wind farms, which the government has set as a national objective to be reached by 2010. But universities, research institutes, and government personnel in Ireland have been saying that the development of ocean wave energy technology would be a true driving force for the nation’s economy and one which would greatly help to make Ireland energy independent. A test site for developing wave ocean energy has been established in Ireland, less than two miles off the coast of An Spideal in County Galway Bay. This experimental ocean wave harnessing site is known as Wavebob. The most energetic waves in the world are located off the West coast of Ireland, says Ireland’s Marine Institute CEO Dr. Peter Heffernan. The technology to harness the power of the ocean is only just emerging and Ireland has the chance to become a market leader in this sector. David Taylor, CEO of the Sustainable Energy Initiative,or SEI, tells us that SEI is committed to innovation in the renewable energy sector. Wave energy is a promising new renewable energy resource which could one day make a significant contribution to Ireland’s electricity generation mix thereby further reducing our reliance on fossil fuels.

Padraig Walshe, the president of the Irish Farmers Association, tells us that with the closure of the sugar beet industry, an increasing amount of Irish land resources will become available for alternative uses, including bioenergy production. Today, renewable energy sources meet only 2% of Irelands total energy consumption. From a farming perspective, growing energy crops will only have a viable future if they provide an economic return on investment and labour, and if the prospect of this return is secure into the future. Currently the return from energy crops is marginal and is hampering the development of the industry. Biomass energies need to be further researched by Ireland.

Your Questions About Renewable Energy For Kids

Michael asks…

What are renewable & non- renewable energy resources?

What are renewable energy resources? Give three examples
What are non-renewable energy resources? Give two examples
btw this is out of curiosity i never really listened in science… =]

admin answers:

Renewable energy is energy generated from natural resources—such as sunlight[2], wind, rain, tides and geothermal heat—which are renewable (naturally replenished). Renewable energy technologies include solar power, wind power, hydroelectricity, micro hydro, biomass and biofuels.

Http://www.eia.doe.gov/kids/energyfacts/sources/whatsenergy.html

Non-renewable energy is energy taken from “finite resources that will eventually dwindle, becoming too expensive or too environmentally damaging to retrieve”, [1] as opposed to renewable energy sources, which “are naturally replenished in a relatively short period of time.” [2]

Fossil fuels:
Coal exists as a mined solid.
Petroleum is a liquid, and forms the basis for heating oil, diesel fuel, and gasoline.
Natural gas is commonly also referred to just as gas. It is mostly methane, and most of the additional material is removed before use as a fuel.
Nuclear energy fuel for fission is mined as Uranium ore, see Renewable energy#Nuclear power.

Goodluck! Sometimes I agree science is BORING!

Jenny asks…

is the solution to the energy problem under our feet?

I refer to geothermal energy. With modern drilling techniques it ought to be possible to drill in many locations throughoiut the world to obtain clean, polutionless heat in unlimited quantity. Why has this idea not taken off?
Oh dear! These answers are all crap.

admin answers:

I was wondering the same thing. Apparently ample amounts of geothermal energy is not accessible in many areas. It is used in a few places here in N.C. At youtube under “alternative energy” many video’s about people all over the world creating a generator that runs strictly on magnets is shown (either they stole the idea from each other or all got the same idea on the same day – not sure lol) but its about the size of a small outdoor central air conditioning unit, and will run an entire house of electricity, and will probably hold up to punishment for about 30 to 40 years before it needs replacing but all utilities would be free as well as zero pollution. The magnets would probably be recyclable for reuse as well. At TEDtalks.com a huge amount of video’s there on future energy inventions, the best of which is being tested at UCLA now in California, of hydrogen powered refrigerators. They actually got one working but its enormous size is not useable but they are working to reduce it in size. The project came up by African nurses that travel from village to village to give insulin injections to those off grid. The trouble is to keep the insulin cold while traveling since it has to be refrigerated. An Ice chest just won’t stay cold in the extreme heats of the arid country so UCLA set out to invent something portable. They say soon, everybody will be able to create their own power with their own water which of course is non polluting as well. Frankly tho the gov talks big about renewable energy, there are many proven techniques to achieve this and they don’t seem interested in any of it. Therefore, I don’t think renewable energy is a true concern of theirs but a front for something “not green” unless its money. If we could all make our own power image the billions lost each year in kick backs to officials who all get free shares in nuclear power etc. They want our dollars and blame it on the environment. They could care less about pollution, or costs or damage to the earth frankly. Its all about the dollar. But check out Tedtalks.com for tons of inspirational video’s. TED stands for Technology, entertainment, and (i forget what D is for) anyway, its worldwide experts in every field you can imagine. They show a super poor boy that lived in africa, saw a book once about wind energy from a traveling library in a bus. Years later he built the most incredible wind turbine out of scraps from the near by dump. This thing looks like total trash and yet he burns like 4 lights in his mothers hut all equivalent to 4 christmas tree lights. Not much light, but for a kid, in a 3rd world country, who only checked out a book once, all that info stuck in his head. Imagine what he could do with an actual battery or LED lights. Its a web site of the most amazing things i’ve ever witnessed. GL on your search. Elon College in North Carolina has 4 geothermal wells dug so far and is going to expand they are so pleased with their new system so check that out online as well. Good luck on your search and peace

Renewable Fuels for Alternative Energy

The Germans have really taken off when it comes to renewable fuel sources, and have become one of the major players in the alternative energy game. Under the aegis of the nation’s electricity feed laws, the German people set a world record in 2006 by investing over 10 billion (US) in research, development, and implementation of wind turbines, biogas power plants, and solar collection cells. Germany’s feed laws permit the German homeowners to connect to an electrical grid through some source of renewable energy and then sell back to the power company any excess energy produced at retail prices. This economic incentive has catapulted Germany into the number-one position among all nations with regards to the number of operational solar arrays, biogas plants, and wind turbines. The 50-terawatt hours of electricity produced by these renewable energy sources account for 10% of all of Germany’s energy production per year. In 2006 alone, Germany installed 100,000 solar energy collection systems.

Over in the US, the BP corporation has established an Energy Biosciences Institute (EBI) to spearhead extensive new research and development efforts into clean burning renewable energy sources, most prominently biofuels for ground vehicles. BP’s investment comes to 50 million (US) per year over the course of the next decade. This EBI will be physically located at the University of Illinois Urbana-Champaign. The University is in partnership with BP, and it will be responsible for research and development of new biofuel crops, biofuel-delivering agricultural systems, and machines to produce renewable fuels in liquid form for automobile consumption. The University will especially spearhead efforts in the field of genetic engineering with regard to creating the more advanced biofuel crops. The EBI will additionally have as a major focal point technological innovations for converting heavy hydrocarbons into pollution-free and highly efficient fuels.

Also in the US, the battle rages on between Congress and the Geothermal Energy Association (GEA). The GEA’s Executive Director Karl Gawell has recently written to the Congress and the Department of Energy, the only way to ensure that DOE and OMB do not simply revert to their irrational insistence on terminating the geothermal research program is to schedule a congressional hearing specifically on geothermal energy, its potential, and the role of federal research. Furthermore, Gawell goes on to say that recent studies by the National Research Council, the Western Governors’ Association Clean Energy Task Force and the Massachusetts Institute of Technology all support expanding geothermal research funding to develop the technology necessary to utilize this vast, untapped domestic renewable energy resource. Supporters of geothermal energy, such as this writer, are amazed at the minuscule amount of awareness that the public has about the huge benefits that research and development of the renewable alternative energy source would provide the US, both practically and economically. Geothermal energy is already less expensive to produce in terms of kilowatt-hours than the coal that the US keeps mining. Geothermal energy is readily available, sitting just a few miles below our feet and easily accessible through drilling. One company, Ormat, which is the third largest geothermal energy producer in the US and has plants in several different nations, is already a billion-dollar-per-year business geothermal energy is certainly economically viable.

Your Questions About Renewable Energy Definition

Sandra asks…

Definitions of non-renewable and renewable energy sources?

I need good definitions for both

non-renewable energy source

and renewable energy source.

admin answers:

Non-renewable uses a source that consumes a natural resource in limited supply. (Oil, coal… We can’t make more so it depletes the existing supply.)

Renewable uses a source that can be taken or grown and therefore can be replenished (Sunlight, wood, corn… We can make or take more and it doesn’t deplete a limited supply.)

~

David asks…

What would happen if we didn’t use renewable energy?

What do scientists fear if people didn’t use renewable energy?

admin answers:

By definition, non renewable energy can’t be renewed. It is finite and it will run out. We don’t have an accurate measure of how much fossil fuels we have left or how long that supply will last us. Many scientists believe we have passed the 1/2 way mark and we will see shortages in less than 25 years maybe sooner if we don’t learn to conserve what we have.

Renewable energy isn’t just about saving the environment, although most of them are much cleaner and produce far less pollution than fossil fuels. Renewable energy is also about ensuring our quality of life and for many it’s about energy independence.

I have solar panels which produce most of my electricity, when the city raised our rates by 20% it made little difference on my bill, if I hadn’t installed my solar system it would have been an additional $50 per month.

Your Questions About Renewable Energy Content

James asks…

What is renewable energy content?

I live in Texas and am looking for a new energy provider. I was looking through the options and it can be filtered by “renewable energy content” ranging from 2% to 100%. What do I want here? I don’t know what it means.
So do I want one that is 100%? Or less? Or the least?

admin answers:

That’s the percentage of the energy you receive that comes from renewable sources and not fossil fuels.

For instance:
Company A provides energy to house B. Company A sends house B electricity that is 65% from coal-fired facilities, 25% from wind turbines, and 10% from solar panels. Company A has a renewable energy content of 35%.

Nancy asks…

Compare traditional methods of making electricity versus renewable energy sources. Is one method better & why?

I believe that renewable energy sources is a better method, but it is more expensive. If you could also provide statistics/facts I would appreciate it!

admin answers:

Wind power is actually very cheap, but the only problem is it can’t provide baseload power. It only provides power when the wind is blowing. However, it can provide power at 7-10 cents per kWh, competetive with coal.
Http://climateprogress.org/2008/05/17/wind-power-a-core-climate-solution/

Geothermal is also looking extremely promising, and can also potentially provide affordable power. It can provide power 24/7 as well (baseload power).
Http://www.ecogeek.org/content/view/2199/76/
http://climateprogress.org/2008/09/27/us-geothermal-is-hot/

Concentrated solar thermal is another great option, and can store energy to be used as baseload. It can be potentially as cheap as coal.
Http://www.ecogeek.org/content/view/2205/83/
http://climateprogress.org/2008/07/28/solar-baseload-update/

There are others like solar photovoltaic, tidal, etc.

There’s no question that renewable energy is preferable to traditional (mainly coal) energy, because it’s clean and the fuel source will never run out.
