Your Questions About Sustainable Energy Solutions

Mark asks…

Why are there no good suggestions for mitigating CO2 levels?

Most of the “solutions” to global warming are just methods to tax companies for unspecified projects to reduce global warming. Most of the suggested solutions are merely schemes to make companies pay for being big bad meanies. Why are there very few people with actual intelligent solutions for reducing the CO2 in our atmosphere? Yes, burning less fossil fuels would do that, but if we gave up fossil fuels we would have mass starvation on our hands. I’m all for sustainable alternate forms of energy, but what of other solutions, such as devising ways to absorb any extra CO2 in our atmosphere?

admin answers:

The only solution is to enjoy an atmosphere richer in CO2, which, if it continues will be beneficial for plant life… Which will benefit all life on earth.

The more CO2 there is, the more plants use it. Compared to naturally growing plants, we could have no appreciable effect at all. There’s a lot of them, not many of us.

What possible reason could anybody ever have for wanting to get a renewable energy training certificate?

What possible reason could anybody ever have for wanting to get a renewable energy training certificate?

admin answers:

While NABCEP or some other certification will not guarantee a job, it does give an advantage to an applicant. They show that the person has at least some basic knowledge and/or skills. It also shows an interest in the industry prior to the job posting.
If you know that you can get a job without it, good for you.
If you have no interest in the industry then don’t bother.
If you want to work in the industry or know what you enough to talk intelligibly about topics relating to renewable energy then get training.

Your Questions About Sustainable Energy

Susan asks…

What has Bangladesh done to establish sustainable energy in it’s Nation?

-What projects, project proposals, development plans and in progress plans has Bangladesh had over the years to shift to sustainable energy? Any open declarations by leaders promising energy sustainability would also be appreciated.

admin answers:

I agree that moving toward sustainable energy is very important for Bangladesh and am excited to see the progress in the solar energy that a previous poster mentioned. One big challenge is that in many developing nations, not just Bangladesh, they can set up small solar outfits, but there is no infrastructure in place to share power generated with the larger community. An even bigger challenge is that even if Bangladesh chose to use only sustainable *sources of energy*, the infrastructure right now would still not be capable of fully supporting is population base. There is still a long road ahead for Bangladesh in terms of sustainable energy (not even going into the more holistic view of sustainability), but the seeds have been planted and I’m confident that the people of Bangladesh are up to the challenge and moving in the right direction.

Should I go to humboldt state university for Renewable energy engineering?

They have my major in environmental resources engineering (ERE) but is there program mediocre? I have the grades to go to a UC (4.1 gpa) but there are no UCs that have renewable energy engineering or (ERE). There is only researching and not ABET credited. So is humboldt a good school academically and will prepare me for a job?

Chris asks…

How much renewable energy can be created and how many jobs would be created with 700 billion dollars?

Apparently the government has 700 billion dollars it’s willing to wage on the banking industry. I was wondering what the environmental and economical impact would be if they invested this kind of money in renewable energies.

admin answers:

The impact would be astronomical. As it is I am trying to fill in the last couple pieces to start a renewable energy (electricity, heating, etc) plant in my state (a plant that would only create a vast number of jobs for people in my state). If the government dedicated that money to scientific research and development of renewable energy our lives and ability to be “green” should only improve. However, keep in mind that technically the government doesn’t have 700 B dollars, but are borrowing it from The Federal Reserve and further increasing our national debt. However, if the invested the money in researching and developing renewable energy resources, it would create a vast number of jobs and possibly help our economy as technology and methods we discover could also be sold to other countries looking to improve their environmental and economic impact. On a personal note, I feel that the government should hold the Bank Heads financially responsible for bailing out their own banks since it was their greed that got us into this situation in the first place. Anyway, I hope I answered your question!

Your Questions About Sustainable Energy Development

William asks…

what is the relationship between sustainable development and environmental awareness?

I’m not quite sure what is meant by sustainable development, or how I could link it with the other one.
I need it for a short speech I’ll be doing.

Any help would be greatly appreciated. Thanks in advance 🙂

admin answers:

Sustainable development is the building of a community in a way that is environmentally friendly and uses renewable resources. Things to look for in sustainable development are:
-transportation: walking/biking/public transportation efficient
-energy: renewable energy source located close by
-city government: new bylaws encourage citizens to build individual homes in an environmentally friendly way

environmental awarness is needed for sustainability, but is more about individuals making green choices in their every day lives.

Helen asks…

How long is the working life of electronic products?

I am writing a paper about the working life of electronic products and the effect and meaning of longer working life on energy saving and sustainable development. Could you help me find some raw materials, data and examples? Thanks a lot!
examples i.e. mobilephone, music player, TV, etc.

admin answers:

You might look into articles and info on Planned Obsolescence which became prevalent back in the 20’s – 50’s as a means to expand production and increase sales by intentionally engineering products to fail within a set lifespan…a lifespan which could have been extended by using better materials or techniques and conserved raw materials. Some countries in Europe established regulations that household items had to last a set time in order to preserve scarce resources after WW II. PO also incorporated fashion as a way to get consumers interested in the latest designs which also increased sales demand. American designer Brooks Stevens popularized the idea of PO in the 50’s.

There are indeed some considerations when designing consumer products which should take into account that it’s also unnecessary to design products to last too long if new technology makes them obsolete and less efficient than newer models will be in the future.

Lifespans of electronics can vary according to design, engineering, available repair parts and use….the art of engineering is to design products using the minimum amount of materials for their targeted intended use and other concerns. There are steam engines which have lasted for decades in commercial use …the Panama Canal lock system has also lasted for decades with minor repairs. Some remotely operated electronic satellite or GPS navigational systems are designed to last for years or decades.

Your Questions About Sustainable Energy Without The Hot Air

Mary asks…

What are some of the things you do to lead a more sustainable lifestyle?

Many years ago, Kate and I developed a Stewardship Model for Tom’s of Maine in order to codify all of the natural, sustainable practices we were already following—such as only using natural ingredients and never testing on animals. The Stewardship Model sets out very specific standards for natural, sustainable, and responsible practices, and guides all of us every day in our decision making.

Kate and I also feel that a commitment to sustainability should be incorporated into all areas of the company—not just the product formulations. Let me share just two examples: our packaging designer, Jack, purchases only post-consumer-waste recycled and recyclable materials and soy-based inks; and my Director of Product Supply, Mark, had some great ideas about using renewable energy sources, so in 2006, we began purchasing wind energy credits to offset 100% of our factory’s electricity needs.

admin answers:

I recycle, grow many of my own vegetables (without pesticides and herbicides), maintain my home so that it is as energy efficient as possible, purchased a new high efficiency washer and dryer pair (uses less gas to dry because washer spins clothes better), keep my tires on my car properly inflated (increases gas mileage), flush my hot water heater regularly (improves efficiency and increases lifespan of heater), use a thermos instead of bottled water (wastes the plastic), buy recycled materials when possible, reuse bags from grocery store, buy soy ink printed materials whenever possible, buy soy ink checks, buy recycled checks, cook from scratch often (less packaging), get regular oil changes/air filter changes (improves mileage), pickup after my dog, don’t smoke tobacco, installed new energy saving windows in our home, and last, but not least…

I write my State Legislators, Member of Congress, Senators, Mayor, Governor, and even the President to ask that they support legislation that will encourage the expansion of alternative energy sources like solar, wind, and geothermal. I also advocate for the use of gray-water systems and other “green” alternatives. Check out these websites:http://www.1000fom.org/

http://www.mngreenremodeling.com/

Donald asks…

What kind of fuel alternative do you think would be best? Electric, hydrogen, ethanol, other?

There a few different options yet it seems that the switch is very slow. What do you think would be the best alternative and do you think it would be a possibility to offer them all to the public at once.
Thank you for the great answers so far everyone. Breath of Wind I agree with most of what you said. We might need to look into different energies for different situations.

admin answers:

Hydrogen takes too much energy to create, there isn’t enough spare land for biomass – electricity is probably the solution since it can be generated from many different sources which can become greener as technology advances. ‘Sustainable Energy without the hot air’ is a good read if UK centered

Your Questions About Renewable Energy Jobs Houston

James asks…

Will special rights for ‘minorities’ end, right about the time white people become a minority?

admin answers:

While the economic recovery is improving the nation’s employment prospects, Hispanics need more help finding jobs, the U.S. Labor Department reported Thursday.

Compared with Anglos and African-Americans, Hispanics have a higher-than-average unemployment rate, less education and higher rate of on-the-job fatalities, according to the report titled “The Hispanic Labor Force in the Recovery.”

“We know more needs to be done to get Hispanics back to work,” Secretary of Labor Hilda Solis said during a conference call with reporters Thursday. She said the report was a fitting tribute to the late farm worker and civil rights activist Cesar Chavez, whose 84th birthday would have been Thursday.

“We know more needs to be done to get Hispanics back to work,” Secretary of Labor Hilda Solis said during a conference call with reporters Thursday. She said the report was a fitting tribute to the late farm worker and civil rights activist Cesar Chavez, whose 84th birthday would have been Thursday.

Solis also announced that Immigration and Customs Enforcement has agreed to suspend worksite immigration investigations for sites where the Labor Department is investigating labor disputes such as a wage and hour, family and medical leave, discrimination or health and safety issues. The agreement was part of a memorandum of understanding between the Labor Department and the Department of Homeland Security.

The agreement will protect workers during wage theft and other investigations, Solis said.

Laura Boston, director of the nonprofit Houston Interfaith Worker Justice Center, which advocates for low-wage workers, applauded the agreement.

In at least two instances she handled recently, workers were deported shortly after they filed complaints of workplace abuse, said Boston. One involved charges of sex harassment and race discrimination and another was payment of wages including overtime.

“We never knew whether the companies called immigration officials or whether it was by chance,” Boston said. “The employer is never held responsible if the worker is deported and isn’t there to testify.”

Unemployment rate
According to the Labor Department report, the average 2010 unemployment rate for Hispanic workers was 12.5 percent, compared with 8.7 percent for white workers and 16 percent for black workers.

On the plus side, unemployed Hispanics spend fewer weeks looking for work than whites or blacks. And a lower proportion of Hispanics are counted as long-term jobless, which the Labor Department defines as 27 weeks or longer.

One reason Hispanics lag behind other workers is that unemployment rates are closely tied to education levels.

Workers with bachelor’s degrees or higher had an average unemployment rate of 6 percent in 2010, while workers without high school diplomas had a rate of 13.2 percent.

Job training
Hispanics at least age 25 who have jobs are significantly less likely to have college diplomas than either blacks or Anglos, according to the report. The proportion is 16.9 percent for Hispanics, 36.1 percent for Anglos and 26 percent for blacks, the Labor Department said.

To encourage more Hispanics to find good jobs, the department recommends enrolling more of them in government-sponsored job training programs for low-income and at-risk youth; providing training opportunities in energy efficiency and renewable energy industries; and encouraging more Hispanics to pursue careers in engineering, technology and science.

High-risk industries
Since Hispanics work disproportionately in high-risk industries such as construction, the Occupational Safety and Health Administration is beefing up its outreach to improve health and safety on the job. According to preliminary data from the U.S. Bureau of Labor Statistics, Hispanic workers had the highest rate of work-related fatalities in 2009.

The department’s wage and hour division is also putting more resources into taking action on companies that misclassify their employees as independent contractors to avoid paying Social Security and unemployment taxes, overtime and minimum wages.

“Misclassification more frequently occurs in industries that employ a large number of vulnerable workers, many of whom are of Hispanic or Latino origin,” according to the report.

Sharon asks…

In Texas Bill White from Houston is running for govenor against Rick Perry the incumbent. Who wins?

White is a very strong candidate. He made the City of Houston, the largest electricity user in the region, the nation’s #1 public purchaser of renewable energy. During his tenure at City Hall, Bill White cut the city’s energy use by six percent, despite double-digit growth in Houston‘s population and thousands of new jobs. White required annual performance reviews of city employees, established performance-based pay programs, and was willing to ask low performers to improve or leave. He established a program to permanently recycle hundreds of thousands of tons of yard waste, reducing landfill costs to taxpayers. Bill White understands that keeping young people in school requires both publicly funded programs and the involvement of civic, business, and religious leaders at all levels of government.

Perry is the longest serving governor and won’t debate or take questions from the media. He has friends running the Teachers Retirement Fund who make millions in investment fees and the School Book Board that recommends altering history to make the chuch more important. Then another friend got millions from the Emerging Technology Fund on appealing to Gov. Perry, after he was originally turned down. Do you think he has been in office so long he doesn’t think all this political corruption matters to the voters?
As an independent voter I found Bill White when I was fed up with Perry’s cronies on the School Book Board who said the Civil War had slaves fighting for the Union and omitted Jefferson as a writer of the constitution instead of bettering our students knowledge.

Houston voters returned White to office with re-election margins of 91% and 86%.
Bill White’s proven track record with law enforcement, earned him the support of sheriffs responsible for 98% of Texans living in counties along the border.

The JFK Profiles in Courage Award is presented to two elected public officials each year. White was chosen for welcoming 150,000 hurricane Katrina and Rita evacuees to the city despite complaints that the newcomers were a drain on local resources. He immediately helped establish emergency shelters and fostered creation of programs to help those who chose to stay in Houston find housing and jobs.

admin answers:

Texans had better hope Bill White does.

Perry is in it for Perry.

Ruth asks…

Should Governments be rebuilding the economy – or developing a new, sustainable one?

Government funds now propping up “old” economic structures (commercial banks) and outdated infrastructure (cars/freeways) – and strategies like Emission Trading Schemes framed to protect polluters “to save jobs” – could be funding pollution-free energy systems etc to answer Climate Change, CREATING new jobs — and an economy aimed at need instead of merely “created wants”. But how widespread is awareness of options? And acceptance of Climate Change warnings?

admin answers:

Yes, however, politicians aren’t really qualified to do so. It is up to “we the people” to make change by changing ourselves. I am optimistically thinking that the anti-change camp (conservatives) are in decline. And that the younger generations are smarter. But those who fear change are still powerful and they are doing all they can to stop progress. Awareness is growing, but it is difficult to see or hear. To see why just visit the “Global warming” category here. The deniers seem to be a majority. And they are very emotional, downright religious, about the issue. Just keep in mind that their emotional state is evidence that they are losing, and they are losing because of their own self destructive emotions. YAY! The so called “evidence” they keep presenting is so wrong it’s hilarious. They are actually claiming that the Earth is cooling, and the ice caps are growing. Their own lies will be their own undoing.

Renewable energy can be good once we have a storage system to store the sun’s, wind’s, etc’s energy and use it when we need it.

It is good for the economy because it is getting more and more expensive to dig up conventionals.

James asks…

What is the difference between a renewable energy source and a nonrenewable energy source? Give specific e?

What is the difference between a renewable energy source and a nonrenewable energy source? Give me some specific examples.

admin answers:

A renewable energy source is one that naturally replenishes itself as it is consumed. Solar energy, for example, will continue to make its way to us for as long as the sun continues to burn, whether we harness it or not. The same could be said about wind, hydro, biomass, etc. (though these are really just indirect forms of solar energy – without the sun, there would be no wind, the water cycle would not function, and plant life would not grow). The only other renewable energy input that the earth sees as a whole is geothermal – heat energy from its own core (though this will also eventually run out).

Another possible example of a renewable energy source could be landfill gas, though this is debatable. As long as humans continue to create a huge amount of organic waste, I guess, then we should be able to continue capturing methane from it.

A non-renewable source, on the other hand, will not be replenished once it is used. Fossil fuels (oil, gas, coal), for example, are considered non-renewable, because they took millions of years to form. Once a barrel of oil is brought up from the earth and burned, it will not be replenished for a long, long time.

Your Questions About Renewable Energy Group

John asks…

How can we make renewable energy less competitive?

There is a serious energy crisis in Australia – even without the carbon tax renewables are now cheaper than building new coal or gas fired power stations.
How can we make renewables more expensive so that the climate change denier industry can maintain their myths?
“A new analysis from research firm Bloomberg New Energy Finance has concluded that electricity from unsubsidised renewable energy is already cheaper than electricity from new-build coal and gas-fired power stations in Australia.
The modeling from the BNEF team in Sydney found that new wind farms could supply electricity at a cost of $80/MWh –compared with $143/MWh for new build coal, and $116/MWh for new build gas-fired generation.These figures include the cost of carbon emissions, but BNEF said even without a carbon price, wind energy remained 14 per cent cheaper than new coal and 18 per cent cheaper than new gas.”
http://reneweconomy.com.au/2013/renewables-now-cheaper-than-coal-and-gas-in-australia-62268

Should we also ban the use of solar energy storage systems (such as the old technology used in http://www.haifa-group.com/products/k_solar/) to support the climate change denier myths that renewables cannot maintain base load supply?

admin answers:

What you’ve quoted was/is inevitable. I could crow “I’ve said this would happen for years” — and I have. But it’s not brilliant insight. Just following the trends.

What you quoted is the obituary for the fossil fuel industry. And (I will crow about and repeat this prediction) — it does not matter what the environmentalists — or the special interests, for that matter — do. The verdict will be spoken in the marketplace. When renewable energy has the competitive advantage (as it now does) the end result will be a drastic decline in fossil fuel use — and carbon emissions.

The same incentive that has blocked action on climate change — pure, raw greed — will now make cutting CO2 emissions an inevitable and unstoppable force.

Your Questions About Sustainable Energy Systems

William asks…

How do places with wind and solar energy sustain their power?

Some places rely on solar and wind energy right? To power their homes and such. How do they use energy in the night or when there is no wind? Do they have something that stores the energy like a big battery or something?

I have to “make” a green city and it will use renewable energy source including solar and wind energy. How would I make the wind and solar energy sustainable and not have shortages of power?

admin answers:

Small places, like a remote house or an island, might have batteries. A large place, like a city, would be connected to a “Grid”, or electrical energy transmission system. If the wind stopped blowing, deep in the night, they would pull energy off the grid, from a nuclear plant, or coal-burning generation station, or hydroelectric project many miles away. A town on an island might have a large diesel generator.

Your Questions About Sustainable Energy Technologies

Chris asks…

Is nuclear energy resource is a clean,cold and sustainable energy technology to fueling the future?

How would u challenge to innovate alternative energy technology to renewable energy resources at cheap price?

admin answers:

Nuclear energy is not “cold”, I am not sure what you meant by that. The whole principle of how muclear energy is used to generate electrcity relies on the fact that it gives off a lot of heat.

It is also not too clean either. The depleted nuclear waste posses a problem of where to dispose of it. It will stay radio active for hundreds of thousands of years, so whereever you put it it needs to be out of the way and secure. Right now, the government is planning to store the stock piles of nuclear waste deep underground under Yucca Mountain (in Nevada I think), but there is a lot of debate over this.

As for sustainable, perhaps not in the long run. There is only so much fissionable material on Earth, it will run out eventually just like fossil fuels. A more long term nuclear energy sourse would rely on fusion, not fission, but this has yet to be practical.

Donald asks…

In the coming future, how can we as a global society, shift our focus from non-renewable fossil fuels to renewable clean energy sources that meet all our growing energy challenges?

admin answers:

Start having fewer children.

The energy demand from 7 billion people is so high that it cannot be met by clean, renewable sources even if these sources became 25% better overnight. Right now we have a choice: have fewer kids and let them live good lives supported by clean renewable energy, or have another seven billion kids and watch them live miserably and fight over whatever declining non-renewable resources exist.

What happened that gas stations no longer have attendants like they used to? For instance Texaco had at least?

two come out to check your car and one would check your oil when permitted to, or wash the windshield. Another would pump your gas,and sometimes a third one would check your tire pressure. If you had a kid with you they would get a lollipop. Is it a combination of corporate greed, over-regulation of government and excessive taxation? Also the fact that the gasoline is way out of proportion to it’s true value. I would love to see a break-through of cheap energy that no government had a chance to stop or regulate come to the people.I am sure that cheap renewable energy is abundant out there,that is being suppressed!

admin answers:

In oregon and new jersey they have attendants pumping gas because self serve is illegal but they dont do any of the other things

Your Questions About Sustainable Energy Definition

Sandy asks…

Why is burning coal not sustainable? Do natural gas and petroleum stack up any better?

Three reasons why coal is not sustainable? And do natural gas and petroleum stack up any better in terms of sustainability?

admin answers:

One reason coal burning is unsustainable from an environmental standpoint is that is finite, and using it will deplete it’s use for future generations. In fact, that is the definition of unsustainable. Another factor is that coal burning releases sulfur, and sulfur dioxide is a component of industrial smog, a noxious fume that kills many people and produces a slew of respiratory diseases. Not to say coal is useless, but its downsides may be particularly pronounced

Each source of energy has its own issues. Natural gas is essentially limitless but is probably hard to capture. Petroleum is also finite and involves drilling. The scales may tip towards natural gas for these reasons

Ruth asks…

What does it take to call a building “green”?

Can you market your building as “green” if it has just a few green features, or does it have to meet certain minimum guidelines? I am thinking about this in the way that the word “organic” is regulated on food labels.

Also – do you think it’s redundant to call something “green” and “sustainable” in the same sentence? I am putting together a sign for my company’s real estate development, and I’m wondering if it is pointless to call the project “a green, sustainable development” or if both words really mean the same thing.

admin answers:

I don’t think there is a green certification, however, there are some things to consider.

Energy star certification.

Green building/ construction methods (hay bale, cob, cordwood, papercreate, adobe, earth shelters… )

Minimizing the use of concrete (pier or rubble trench foundations )

Passive solar design

Solar hotwater

Separate grey water systems

Sustainable certified lumbar

The list goes on and on

The term green is probably the best way to go. You are opening a big can of worms if you use the term sustainable. Sustainable has a real definition. A friend of mine sells “sustainable” clothing, woven with thread from banana leaves. That is not sustainable in and of itself. Scientists have predicted that bananas (the type we eat) will soon face a blight that we can not protect them from, ending its presence in our super markets. Although the thread may be a commendable effort at maximizing a resource that otherwise may have been left unused, bananas in general are not a sustainable resource. Every material in the house would have to be made from a sustainable resource (like wood and hay) and would exculde non sustainable materials like (metal, plastics….). Then again, there is no MARKET definition for sustainable.

If you are interested in charging more money for a “green development” and using expensive things like bamboo flooring, or salvaged lumbar from the bottoms of lakes and rivers, or anything ridiculously expensive and unpractical, then forget everything I said. Just put whatever you want on the sign, spit in thier face, and ask them for $400,000

Your Questions About Renewable Energy Jobs

William asks…

How in demand will renewable energy jobs be in the near future?

I’m really worried about the economy and looking for a quick certification so I can have some sort of qualification in case it totally goes under. I found a 14 credit hour renewable energy certification at a community college. Do you think this will do any good for finding jobs?

admin answers:

Very high demand for scientists and engineers and designers..

Jenny asks…

Effect of using renewable energy on the economy?

I’m doing a project for my economics class and I have to explain several different ways in which transitioning to renewable energy and relying less on fossil fuels will effect the economy. So far all I really have is that it will create more jobs. I have to be able to write a 5 page paper on this. Please help, this is due tomorrow!

admin answers:

Using less coal will mean fewer coal miners.

Using less petroleum will mean fewer guys working on those deep ocean well drilling rigs.

Using more Wind will mean more money for the farmers that have windmills on their land. And Studying the effects of killing birds from the blades.

Using more solar will mean lots more folks trained on how to install solar panels.

All this also means changes in College courses to prepare for degrees in these areas.

Less petroleum imported will mean a better balance of payments for Commerce.

Less petroleum means less reliance on Air transport and a shift to higher speed trains.

Airplanes are one of the least efficient users of petroleum. Soon Air travel will be only for the very important, rich or for a very infrequent trip.

People will live closer to work unless public transit is available.

If we go to food based crops for energy it will mean we starve people and start wars over food. (BAD idea)

conservation will be very IN due to the higher cost per watt from renewable sources.
