Here’s a concept in small wind for readers to check out. A few points: It’s not new. A few years ago, there was a nearly identical idea that came and went, when investors figured out that this concept, as all …

In preparation for my first book, “Renewable Energy – Facts and Fantasies,” I interviewed Ray Lane, then managing partner of Kleiner Perkins, one of the world’s great venture capital firms, who told me about his stance with his prospects, “You …
Germany finds itself in a unique position among the countries of the world, in that it’s gotten rid of both coal and nuclear and now depends quite heavily on renewables. Germany is the world’s third largest economy, behind the United …

Obviously, this is pure crap. 1) Vertical axis wind turbines (VAWTs) are less efficient than their horizontal counterparts. More importantly: 2) Wind turbines are not cited in areas with buildings that block wind currents. 3) Cities are not built in …
A proponent of the wind turbine shown at left writes: I commented this 6 year’s ago . It is so simple even if you put in small stream 1 000 000 small turbines like this one, you will have more …
The three-bladed wind turbines we see all over the world extract about 90% of the theoretically available kinetic energy from the air that moves through them. A 60% would violate the laws of physics. Of course, these people are not …
Though there’s nothing theoretically impossible about the story at left, I doubt it’s true. That’s because Denmark has a superabundance of renewable energy due to its phenomenal wind resources. When it has too much for its own consumption, it sells …
Re: a supposed new mode of renewable energy generation, a representative of the “Sumner County Kansas Republican Party” writes: No one care (sic) what power they can harvest/generate, the question is “what tax benefits are there?” I’ll file this comment …
Wind energy is based on removing some of the kinetic energy from a certain volume of moving wind and converting it to electricity. Think of the volume of wind that passes through the area bound by the circular movement of …
