Understanding the Difference Between Energy and Power: Critically Important in Clean Energy Discussions

Understanding the Difference Between Energy and Power: Critically Important in Clean Energy DiscussionsIf I had to identify a single pet peeve of mine, I might say that it’s people in the energy industry who don’t know the difference between power and energy.  Power is the rate at which energy is generated or consumed, or more accurately, is changed from one form into another.   Read more ›

Advocates of Nuclear Energy Would Be Well-Advised to Chill Out a Bit

To my chagrin, and my astonishment, the advanced nuclear people I’ve been hanging around with recently love to bash the supporters of solar and wind. Are they hired hit-men for the nuclear industry? I don’t think so; lots of them have PhDs, and I’m convinced that there is no real money-motivation here. Read more ›

Seattle Tops List of Sustainable Cities 

Seattle Tops List of Sustainable CitiesHere’s an article that lays out exactly why Seattle is named as the most sustainable city in the U.S.   There are numerous ingredients that go into this calculation, but among them, of course, are energy and transportation.  From the article: “Seattle is one of only five cities in the nation where less than half of commuters are driving alone to work. Since 2011, Seattle has seen a 59% increase in bicycling and a 27% increase in pedestrian traffic.” Read more ›

Could a Variety of Jatropha Play an Important Role in Biofuels?

Could a Variety of Jatropha Play an Important Role in Biofuels?Those of you keeping track of the evolution of biofuels may be interested in this piece on a hybrid variety of jatropha.

Personally, I view the whole biofuels enterprise as a snooze.  We’re trying to replace the source of the 15 terawatts of energy we Earthlings consume, 80% of which currently comes from burning hydrocarbons, a process that is rapidly destroying our planet. Read more ›

Underwater Compressed Air Energy Storage (UW-CAES)

Underwater Compressed Air Energy Storage (UW-CAES)Here’s an idea that shows the enormous range of thinking outside the box of which clean energy inventors are capable.  Use off-peak energy to compress air into a submerged bag.   My reaction: Can this be done?  Sure.  Can it be done cost-effectively?  Not in a million years.

Frequent commenter and senior energy analyst Glenn Doty should be along here any minute.  I’m sure he’ll agree, given his position on even the best-case scenarios for CAES.

From Guest Blogger Audrey Clark: What We Can Learn About Solar Tech From Big Business

What We Can Learn About Solar Tech From Big BusinessApple is a well-known consumer tech company, but it is also a corporation that has its stakes in major areas of solar tech. On the one hand, the company has been working hard at figuring out how to embed solar tech into its consumer products to make them better. At the same time, the company is also focused on developing working power grids, starting with singular solar farms and then expanding to networked farms. So how is it that Apple is doing something with solar power better than what others have done? After all, solar tech has been around for a while; it’s not a new invention just created a few months ago.

2GreenEnergy Intern Poses Questions on Organic Food, Climate Disruption

2GreenEnergy Intern Poses Questions on Organic Food, Climate DisruptionA young lady who served one of our famous internships here at 2GreenEnergy (and did a fabulous job, btw) wrote me this morning, asking for answers to two questions:

Hello Mr. Shields.  I had a question for you that I thought was interesting. It’s not completely about energy efficiency in a business but it does have to do with the environmental issues many of those companies face. The organic food movement is huge right now and I wanted to get your stance on something. The organic food industry makes its money by stating the fact that their food is grown pesticide free and not tainted, basically. However, how organic can food really be when our soil has such a legacy of pesticides ingrained in it already and when not one place on earth, where these foods are grown, is probably completely void of pollutants? I just thought it was interesting because we put so much emphasis and we are willing to spend so much extra money on food deemed organic, yet how organic can something be in today’s world?

Energy Pragmatism

Energy PragmatismReader Jerry Nolan writes: “Most greens who advocate wind, solar, and conservation are anti-nuclear,” and he’s 100% correct in this.  However, like my friend, GreenTech Media’s Stephen Lacy (pictured), I think of myself as an “energy pragmatist.”  This means, at a minimum, that I keep an open mind about the pros and cons of all forms of energy—especially nuclear, since it can take on so many radically different forms.

It also means that we need to confront the cold, hard truth about the enormity of the problem we’re trying to solve, i.e., finding a new source for 15 terawatts of power, 80% of which currently comes from burning hydrocarbons.  Very few people who are rabidly anti-nuclear have any idea how much damage coal causes each day.
