There are those who think that renewable energy is overhyped, won’t scale, is doomed if federal incentives get whacked, etc. Just don’t tell Siemens. One of the world’s 50 largest companies, Siemens shows no signs of curtailing its commitment to wind; …
Here’s a good discussion of what I call the “no free lunch” theory of renewable energy: everything we do, whether it’s solar, wind, hydrokinetics, etc., comes with a non-negligible ecological cost. The issue, obviously, is objectively identifying all costs – …
We hear a lot about grid parity, don’t we? That’s the point at which the cost of energy generated by solar, wind, and other renewables is the same as that generated from conventional sources. The author of this article on …

Here’s an article that suggests that concentrated solar power (aka solar thermal) may be on its way to greatness in Africa, and discusses the path by which CSP can achieve that stature. In terms of renewables generally, the author points …
Whenever I come across an article like this on microgrids, i.e., “islands” of distributed energy generation, storage, and consumption that are not connected to a power utility, I look at the numbers. If I were a utility exec, how scared …
My friends at Eos Energy Systems tell me that far more than 95% of the world’s energy storage is pumped storage hydroelectricity (PSH) – which is one of the reasons they believe that their breakthrough in zinc-air batteries is so …
