Geothermal energy is a renewable, plentiful, clean and essentially limitless source of energy that can use a variety of applications. Geothermal is defined simply as heat from the earth. It tends to get less attention than wind, solar, and biofuels, but one myth the Geothermal Energy Association (GEA) says floats around – that the industry is experimental and technologies not widely used – is simply not true.

Geothermal goes as far back as the Paleo-Indian, who first used thermal hot springs. Such district-wide heating projects have been in continuous use since 1892, such as in Boise, Idaho and in Oregon. In 1904, Italy opened the first large-scale geothermal electric plant and it is still operating today. The first U.S. geothermal plant opened at The Geysers in California in 1960, and produces 11 MW of net power, continuing operations today as well. Geothermal power is used in 21 countries. The Philippines derives 27% of its electricity from geothermal sources and little El Salvador gets 26% of its electricity generation from geothermal. However, what is in use today – about 10,715 MW installed — is but a fraction that could be used, and the industry has nowhere to go but up.

When I mentioned 2GreenEnergy’s client Canefields USA in the past, I think I neglected to point out the video on the company’s website, detailing how paper from sugarcane waste is actually made. The world now has access to paper made from carbon-neutral processes that do not come along with bringing down trees. How cool is that?

I suppose I thought that a plant like this in a developing country would look a bit low-tech – but wow, was I wrong. And, even brighter news is that it’s only a matter of time until this technology finds its way to Brazil – and perhaps the US – creating a more sustainable solution for serving the needs of the Western Hemisphere.

A renewable energy surge is happening in New Jersey, and it is focused on solar.  Con Edison Development (NYSE: ED) along with Panda Power Funds broke ground on a 20 MW solar electric generating station on October 20th, 2010. Located in Pilesgrove, NJ, the farm will have the capacity to power more than 5,100 homes and will create more than 100 construction jobs.

Construction of the 71,400 panel farm will start in the Spring. New Jersey State Senate President, Stephen Sweeney, said at the groundbreaking: “…This project is proof that our commitment to strong public-private cooperation is a model for success. The future (more…)

I was somewhat surprised at the pushback I received to my recent post suggesting that the PBS NewsHour should not accept sponsorship money from Chevron, as such a relationship could affect PBS’s objectivity in its coverage of the energy industry. A few people asked me in a huff for specific proof that such a relationship has affected NewsHour reporting.

I openly admit that I have no proof.  My point isn’t that something unseemly has happened; it is that something could happen.  It’s a situation to be avoided — kind of like the late king of pop Michael Jackson’s having young boys sleep in his bed with him (regardless of what happened): it’s just a bad move.

Fifty-eight percent (58%) of U.S. voters think finding new sources of energy is more important than reducing current energy consumption. And sixty percent (60%) think investing in renewable energy sources like solar, wind and wave energy is a better long-term investment for the U.S. than investing in fossil fuels. These views were revealed in one of the latest Rasmussen polls (October 10th.)

Forty-two percent (42%) believe there is a conflict between economic growth and environmental protection, the highest finding since May.  The margin of error is +/- 3% with a 95% level of confidence. Field work for Rasmussen is conducted by Pulse Opinion Research, LLC.

Voters in the Rasmussen poll give mixed results to President Obama for handling energy: forty percent (40%) give him a rating of energy issues as good or excellent, the same as last month, while thirty-nine percent (39%) give him a poor rating.

The number of voters who believe global warming is a serious threat is trending down since last November.  59% today (more…)

Earlier today, a friend sent me a link to this discussion of electric vehicles on Techcrunch, one of the great blogsite successes of the past few years.

The article features the way-cool work of Plug-In America in its ongoing advocacy position for EVs.  The discussion beneath, however, was rather alarming.  Either the site is full of shills from the oil companies, or there actually are well-educated young people who believe that EVs offer little or no ecological advantage over internal combustion engines.

It seems they needed me – a guy old enough to be most of these commentors’ father – to point out:

A point worth mentioning here is that we could 90 million EVs on the road this afternoon, charge them with off-peak (overnight) power, and not put ANY additional load on the grid; most of that power is thrown away, as it’s too expensive to store.

I’m always amazed at how the auto industry continues to spin out new ideas – even at the expense of integrating concepts that, I would think, would have little chance of being seen together. Check out this video of Porsche’s new plug-in hybrid, the 918 Spyder, a car that marries a 500-HP V8 with a 218-HP electric motor. The result is a considerable rocket (0 – 62.5 MPH in 3.2 seconds). But still the messaging is rife with ecological sensitivity: “lower fuel consumption,” “lower CO2/mile,” and “one of our [Porsche’s] answers to urgent environmental concerns.”

To me, blending the concepts of high performance sportscars and eco-friendly driving is like serving chocolate sauce over tunafish, or a dill pickle spear on a bowl of strawberry ice cream.  Either one by itself is wonderful, but together they’re a bit discordant.  Most people with real concerns about the environment aren’t impressed with 700 HP.  My recommendation: don’t mince words; just go for it.

A friend and I were discussing a mutual acquaintance who believes that the Earth is hollow – a radical theory to say the least. My friend writes:

Of course, I’m more than dubious about this hollow Earth stuff, but here’s an interesting conundrum to contemplate. Given Earth’s current gravity, is it really possible that dinosaurs were able to get as large as they did? Why aren’t land creatures today no larger than an elephant, which weighs a fraction of a T-Rex or other gigantic dinosaur? Did Earth have less gravity at one time? If so, how?

To which I reply:

I can’t speak to that one — it really IS interesting. I just think the accepted theory of the formation of the planets is so overwhelmingly compelling that a hollow Earth — or any other phenomenon that would result in a significant change in the force of gravity at the Earth’s surface — would be extremely hard to buy. Remember also that the dinosaurs were here only 65 million years ago, which is fairly recent in geologic time; almost 99% of the four-billion-year life of the Earth was before that time.

Anyway, I hate to sound like I have no intellectual curiosity, but my focus at this point in my life is more on the present. Check out this piece on the politics of global warming.  I’m very worried that power politics is in the process of winning out over science, and that we really are running headlong to the ruination of this planet. I’m afraid this stuff is getting completely out of hand.

Rice University in Houston, Texas announced the creating of a clean energy think tank. It will study and strategize environmentally sound policies for current and for new energy sources. James Tour is heading up the collaboration. He is a Rice University professor in Chemistry who wrote a paper about Nature Materials which discusses rapid expansion of solar and wind energy and the long-term need for carbon-based energy.  Carter Kittrell, a Rice research scientist, and Vicki Colvin, Rice’s Pitzer-Schlumberger Professor of Chemistry join the collaboration.

Rice already has made a number of initiatives in the world of green, including having guidelines for professor and students in the conservation of energy. Several of its buildings have been rated LEED-certified.  One of its publications from the Ecology department covers stories on a sustainable, clean energy future.   (more…)

A few readers have objected to my post suggesting that Chevron’s sponsoring the PBS NewsHour could warp the objectivity of the coverage of the energy industry. Most of these responses point out that I have no proof that Chevron’s presence actually has created a slant, which is true. Others say that energy does not have to be an “us versus them” story.

I’m not a combative or suspicious person by nature, but there is no way that anyone can analyze the energy industry and not conclude that it is essentially “us vs. them.” The oil companies employ 700 lobbyists whose job it is to influence our government in its favor. If they didn’t see the need to purchase that favor, they wouldn’t employ the biggest lobby on Earth. And they’ve been fantastically successful; (more…)
