I awakened this morning to an interesting question in my inbox from frequent commenter and 2GreenEnergy supporter Brain McGowan, who asked: What’s your take on this hydrokinetic device?
Coincidentally, a colleague of mine showed me an extremely similar device about six months ago and wanted my opinion, as a mutual friend was considering a significant investment in the company that was developing the technology. (more…)
With the climatic conditions of planet earth rapidly changing, changing humidity levels, global warming, extreme weather conditions and many other such events are shaping earth’s current climate. All of these changing factors have influenced all forms of life on earth. Global warming, in particular, has resulted in changing living and reproduction patterns of various life forms. (more…)
Here’s article from one our 2GreenEnergy interns, Marcela Carvalho, an energy engineering student at Saint Francis University in Pennsylvania. I was flattered to know that “some of her professors” suggested that she contact us, and I eagerly welcomes her to the team. As Marcela is from Brazil, she had no trouble assembling this piece on the trends in energy that exist in her home country.
Brazil has become one of the most powerful countries in terms of renewable energy sources, due to its privileged geology compared to other countries; Brazil enjoys an enormous availability of energy sources. (more…)
Here’s an article from the online version of Inc. Magazine written by a young man who somehow picked three cleantech companies and heralded them as “the hottest on the planet.” I came across this because one of them happened to be WindStream, the folks I’ve mentioned several times for their very interesting and reasonably priced product in “small wind” (the name given to wind turbines under 50 KW).

Everyone with lungs should be in support of the Sierra Club and what they’ve done with their campaign called “Beyond Coal,” which has brought the awareness of the issue to tens of millions of Americans who otherwise would have been clueless on the subject.
And, as one would expect, the Sierra Club is not too sanguine on the U.S. Congress and its approach to the Keystone XL Pipeline either. In an email I got this morning, they write: (more…)
In his reference to my post on the Bill and Melinda Gates Foundation, a reader notes: At the end of this century people will look back on what the Gates Foundation spent millions or even billions of dollars on and declare it was a huge waste of money and should have been spent to control greenhouse emissions.
Bill Gates has not been entirely absent from the clean energy space, but it’s clearly “not his thing.” I’m not sure why this is, given his powerful intellect and his facility with math/science. (more…)
Would be funny if it weren’t tragic.
First story here.
Second one here.
Nothing more to say this afternoon.
I just came across a start-up that proposes to convert some of the chemical energy in landfill waste (MSW – municipal solid waste) into glucose, and then sell it to ethanol producers. I had promised myself that I wasn’t going to get involved with a discussion with these people, but eventually I broke down and wrote: (more…)
Every couple of weeks there is something in The Writer’s Almanac that seems particularly relevant to the issues we discuss here at 2GreenEnergy. Perhaps it’s the anniversary of a scientific discovery that changed the way we understand energy, or the first publication of a book that shaped our viewpoints on justice, or the birthday of a leader who transformed our civilization.
Here’s a quick story that Garrison Keillor, the publication’s creator, told in passing a few decades ago on his radio show. He seldom mentions himself or his private thoughts, and this was a rare exception. He said (and I paraphrase): (more…)
The “green” building movement has caused dramatic changes in the construction industry over the past few years. As consumers became more aware of the impact of traditional construction activities on the environment and the use of resources such as wood, water and energy, they have sparked a revolution in the industry. This trend is quickly gaining traction and making waves, and could be a huge indication of the future of the construction industry. (more…)
