The Future: Distributed Energy Production and Storage

Published under Energy, Environment

Production of energy is currently the realm of large corporations, which have centralized facilities that, typically, burn fossil fuels. The obvious side effect, is that while burning fossil fuels creates energy, it also creates carbon dioxide. Approximately 85% of our worldwide energy comes from the burning of fossil fuels. About 6% comes from nuclear, and the rest is “renewable” energy, with the largest slice of the pie coming from hydroelectric.

What’s good for GM

…is not what’s good for America. Earlier this week, GM sent representatives to campus to attempt to sell their idea of a hydrogen car. The story is poorly written, but what do you expect, it’s a probably a communications major. By “poorly written” I don’t mean that it has poor spelling and grammar — there is plenty of that around here. No, I mean it sounds like a press release from GM.

McCormick started his quest to create a fuel-efficient vehicle as a UA student concerned about rising gas prices. He quickly realized then that his lifestyle of fuel consumption was no longer an option for him, or for car owners anywhere, he said.

Judging from the picture, I’d guess that gasoline prices when McCormick was a university student were around $0.25 per gallon. Nothing wrong with that. But then he “quickly” realized wasn’t an option. Wha? I don’t think so. But giving him the benefit of the doubt, why did it take 20-30 years (again, guessing) to make a prototype?

He goes on,

He explained that although most people tend to favor renewable energy like solar or wind, the hidden problem is the lack of an efficient way to store them, and the distribution ability is very limited.

Ethanol, McCormick explained, is a viable option, but only if it is not shortchanging the public of food. General Motors has invested in two companies - Coskata and Mascoma - that endorse ethanol use but only cellulosic, or non-edible products in order to make ethanol.

I’m not a fan of ethanol. It is a band-aid, not a solution. But casually dismissing solar and wind power like this not acceptable. It’s true that energy cannot be stored for very long or very efficiently right now. But in the time-line of everything that works, there was once a time when it didn’t work. It seems that a possible solution might be to use renewable non-polluting energy to make hydrogen, which can be stored.

“The next president and his policies are going to determine a lot of the future of these vehicles,” McCormick said. “We (GM) are willing to put in the money and the technology, but we really need favorable government policies. These cars are going to be more expensive, and tax breaks would encourage consumption by the public.”

True. But the difference between the candidates isn’t that large. If you’re looking for government handouts to corporations, then McCain would probably be a better choice. If you’re worried about the environmental impacts of pollution, then Obama would be a better choice.

But that pretty academic by now. When the pundits start describing Georgia as “too close to call”, it’s over. If Obama doesn’t get 350 electoral votes, I’d be surprised.

Help Break Atmoz: DonorsChoose

Published under Education, Environment, Science

Scienceblogs is running their DonorsChoose drive again. I couldn’t make up my mind which one (or more) to donate to. There are a lot of worthy projects. Some teachers are asking for basic things like paper, pencils, hole punchers, and safety glasses. Luckily, Davig Ng at The World’s Fair found 3 very deserving environment related projects.

For every Atmoz reader that donates to one of these projects, I’ll make a donation of the same amount. If you decide to donate, please note it in the comments here. In the event there are no takers, I will split $100 among the 3.

Is Really Green Racing in the Future?

Published under Climate Change, Energy, Environment

Via the Scientific American Observations blog comes news that during its 2009 season the American Le Mans Series will be introducing a Green Challenge. Details can be found on the ALMS website.

I must admit that I like racing. Not because I’m a fan of watching car drive in circles using internal combustion engines that produce unnecessary CO2. Or that the fuel they use could be used for many other more useful purposes. I don’t know why I like it; I imagine its for similar reasons that I like other sports such as baseball. It’s just fun to watch sometimes.
