Here’s an article that compares the two main competing technologies in concentrated solar power (CSP): linear Fresnel lenses vs. parabolic troughs. The main issue, of course, is the cost of the reflectors themselves, as well as the apparatus whereby they …

Tomorrow night marks the start of a trip out of town for me. I’ll be headed to San Francisco for a couple of meetings, including coffee with my friend Fareed Sfard, CEO of solar thermal start-up Ahura Energy. Then it’s …
Here’s a good article on a recently completed solar thermal tower (aka concentrated solar power or CSP) in the desert between Las Vegas and Reno, NV. The thing to like about solar thermal, as we’ve often discussed here, is that …
Here’s an interview with 2GreenEnergy Associate Agostinho Miguel Garcia, who’s working on a very interesting solar thermal (concentrated solar power / CSP) project in Namibia – a country whose conditions are perfect for CSP. Agostinho’s headquartered in Lisbon, but works …
Here’s another in our ongoing series of infographics, designed to offer young people and clean energy newcomers an accessible introduction to the subject. Here, we provide an objective look at the “pros and cons” of solar. While we advocate in …
It’s the birthday of Alexander Graham Bell, whose telephone came as the accidental consequence of his interest in developing a tool that might teach deaf people how to speak. To me, it’s another reminder that accidental discoveries are extremely common. …

[youtube http://www.youtube.com/watch?v=AgKgc_Oo1fI]As part of my series of basic videos for newcomers on the main renewable energy technologies, I lay out the basic forms of clean energy and say a few words about photovoltaics, solar thermal (aka concentrated solar power or …
I wrote recently that it’s impossible to predict the ROI associated with solar thermal (aka concentrated solar power or CSP). What I was referring to was utility-scale CSP. Personally, I think the future will hold significant reductions in costs and …
