Your Questions About Renewable Energy

Betty asks…

why is it important to have renewable energy?

Which types of renewable energy are being utilized in the US and which are in the “design” phase?

admin answers:

One type of renewable energy for cars is the hydrogen fuel cell. Hydrogen is all around us making it easy to get, plus as an added bonus it doesn’t emit any CO2 emissions. The only thing that comes out of the exhaust is water. Honda has released a hydrogen fuel cell car for lease. It’s called the Honda FCX Clarity. There are four problems that need to be overcome with this source of energy. One is to make hydrogen fuel pumps easily available. Two is to make the car travel more than two hundred miles before refueling. Third is to make the Hydrogen more safe to transport. Hydrogen is more combustional than gasoline. And forth is to make the hydrogen cost a less.

Chris asks…

I am looking for renewable energy companies that trade on the stock market?

Does any one know any renewable Energy companies that trade on the stock market. I am having a hard time finding them.
Do you have any idea how I can find any more names?

admin answers:

Yahoo Finance or MSN Money are good and free tools you can use. Just search for ‘renewable energy’ or ‘green’ companies. Good example of one start up that is getting lots of attention is Beacon Corp (BCON).

Your Questions About Renewable Energy

Joseph asks…

What kind of Engineer deals with coming up with new ways to use renewable energy?

When i say renewable energy i mean like solar power, wind power, hydroelectric power . Is there a certain type of engineer who works in these areas? Where is a good place to go to school for this type of Engineering.

admin answers:

Renewable energy is a specialized area of engineering. There is no engineering degree that focuses solely on renewable energy. The closest ones that I can think of are Chemical Engineering and Mechanical Engineering. The principles of chemical reactions are important in the study of energy. But to design and construct the harnessing devices requires knowledge of mechanical engineering.

Every engineer is taught the basics of every engineering discipline so even Computer Engineers can qualify if they specialize beyond their undergraduate education.

If you live in the Philippines, the best school to go to is of course the University of the Philippines. Among private universities, De La Salle University – Manila is best, followed by MAPUA. Ateneo De Manila’s engineering is handled by the Physics department as I have been told so I would be hesitant towards that school. The University of Sto. Tomas seems to have strong engineering background as well, but I have no certainty about that. In choosing the right school, accreditation of the engineering department and not just the school accreditation is important.

Mark asks…

What would happen to all the existing gasoline automobiles if renewable energy took over?

I’m not saying I’m against renewable energy. I’m just wondering – what would everybody do with their car that runs on regular gas?

admin answers:

I think we are a long way from renewable energy replacing the combustion engine. When I think of renewable energy I think of electricity for houses and businesses. But when we do settle on one or a few technologies to replace the conventional gas engine. I think there will be a transitional period where new cars will have the new technology but we will still have the infrastructure for gas engines, it could take decades to phase out the older cars.

Here in CA we have tougher emissions laws, so if you have an older car you could get an exemption for not passing emissions, it was a program that let just the oldest cars be exempt, then every few years they let a few more years be exempt. Now all the cars that were sold after the date the laws went into effect have to pass smog, if you didn’t buy the car in CA then you will need to get a catalytic converter put on it to pass. Millions of cars are junked each year, when you turn in an old clunker when you buy a new car they are often sold for scrap and they are taken off the road. All that being said, to say that people won’t be forced to convert cars or get rid of them for many many years.

Thomas asks…

What universities offer online courses in renewable energy or green related fileds?

I am interested in the renewable energy, green field, etc. And i want to know if there are some universities offering these kind of online courses.

admin answers:

All courses and degrees dealing with “renewable energy” or “green field” without prerequisite degrees in Science or Engineering are bullbleep.

Students need a background in Science or Engineering (preferably Engineering) before they can understand energy issues. Otherwise, graduates of these phony courses just become loud and ignorant shrieking nuisances.

Michael asks…

When are republicans going to start supporting renewable energy?

Republicans are the biggest opponents of renewable energy legislation in Washington right now. Why?

http://features.csmonitor.com/environment/2008/07/31/gop-lawmakers-block-renewableenergy-credit-bill/

admin answers:

We do support renewable energy. The sources of renewable energy are just not reliable and we do not have enough of any of them right now. What most republicans want is for there to be a comprehensive energy package with nothing off the table. That means drilling, solar, nuclear, wind and whatever other sources can be invented or created. We are not slaves to the environmentalists who want only so-called clean energy. Democrats seem to be in the environmentalists pockets and are not willing to discuss anything except what the environmentalists will accept.

Your Questions About Renewable Energy

James asks…

What is the role of renewable energy in addressing climate change?

What are the advantages and disadvantages of renewable energy in to climate change? Whatare the contributions of renewable energy to climate change?

admin answers:

It is a political term to describe power sources that don’t emit much CO2 but which can’t actually provide the power our civilisation needs (so far no country has managed to get much more than 20% of their power from wind or solar and even then they had to rely on their neighbours’ hydro and nuclear as well as their own coal to prevent the grid from collapsing). Hydro is the main renewable energy source for electricity production right now but is opposed by most of the people who claim we need renewable energy (and unlike their opposition to nuclear power they actually have good reasons to oppose hydro).

They are used mainly to delay the switch to nuclear power (which despite being not renewable should be good for millions of years at higher than current energy use) that would allow us to actually solve the global warming problem and thus contribute to global warming by keeping the fossil fuel industry in business.

Basically the way it does that is that a bunch of windmills get built and start supplying power to the grid but because of natural variability in the wind they don’t provide that power all the time (20% of rated capacity is considered pretty good for wind) nor can we control when they provide their power so to use wind power you need a source of backup power that is reliable and usually that means fossil fuels (nuclear could be used but if you use nuclear for that then you may as well not bother with the windmills because the windmills would not reduce CO2 emissions or save money). Solar is less variable but PV cells cost a lot more and it still needs backup at night and partial backup on cloudy days. The need for backup means that the fossil fuel industry still gets to exist (and continue pumping CO2 into the atmosphere) if the way to address (if very badly) climate change is to use wind and solar.

Hydro and geothermal have the reliability to be used for baseload although they only work in some locations and hydro power probably won’t be used where it can be because of the massive environmental damage building a dam causes.

Wave and Tidal power when you calculate how much energy there is turn out to be way too diffuse to be useful. Biofuels show promise but not much because you need land to grow them on and that land could be better used growing food or even being turned back into forest.

William asks…

What’s the difference between renewable energy and environmental resources engineering?

Oregon Tech offers renewable energy engineering and Humboldt State offers environmental resources engineering. When I look at the differences between these 2, I couldn’t tell so what should I do? I’m a senior in highschool with a 3.6 GPA

admin answers:

Oregon tech is a masters degree. Humboldt is a bachelors. The humboldt state program is a more traditional “civil” engineering program, which is sort of parallel to environmental engineering. This is probably the safe bet, as these jobs are always in demand. The civil/environmental/water resource engineer does a variety of work and large and small projects. Treatment plants design, sewer line design, water line design, levee design, floodway studies, water quality studies (streams, lakes, rivers, industrial discharge water quality, etc…). Also, alot of report preparation, dealings with the EPA on almost all projects, public meetings explaining projects, drainage studies, storm drain design, environmental clean-ups… The list goes on…

As for the Oregon tech program, it seems more like a ‘green’ energy engineering program. I only briefly looked at the curriculum, bit it appears that they teach the fundamentals of todays renewable energy markets, and also emphasize research into those technologies. This type of engineering is more volatile and risky from a career standpoint, as those companies who engineer renewable energy are often start-ups, government subsidized, and so forth… With the price of copper so high now, the wind energy market is dying fast, since it is effectively impossible to cost effectively use wind power now… Same with solar, the rare earth minerals needed to produce the panels are in short supply, and getting more and more expensive, and on top of that, I belive the U.S. Has only one location where such minerals are mined, the rest are controlled by the Chinese overseas… Thats worth checking into, but I believe that to be the case currently. At any rate, perhaps the graduates from Oregon Tech will engineer new renewable energy sources that we haven’t heard of yet… That seems like the type of program that is… Highly research and innovation based. So a career in that line of work you have to understand the emerging technologies, strength of the markets, and the politics that usually go hand in hand with renewable energy technologies…

Both are ABET accredited engineering degrees, so you’ll be able to become professionally licensed once you complete your degree… That is a good thing, and you’ll want to avoid a program that isn’t accredited.

Good luck.

Your Questions About Renewable Energy

Steven asks…

How is renewable energy good for the economy?

Can renewable energy truly be good for the economy, and how so?

admin answers:

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.
