Understanding the Efficiency of Solar PV
Why aren’t solar PV cells more efficient? Here’s an answer from a physicist who looks at the problem from the perspective of the Carnot Limit, i.e., the theoretical limit to the efficiency of a heat engine, which is a function …
Putting Concentrated Solar Power Breakthrough Into Context
Frequent commenter and renewables DIYer extraordinaire Brian McGowan writes: I know you like CSP (Concentrated Solar Power). Here is an interesting system. If only they would just use the steam to turn turbines instead of getting oil out of the …

Concentrated Solar Power: Is There a Reason To Stay Hopeful?
When I conducted my “25 interviews with subject matter experts” for my first book on renewable energy (Renewable Energy – Facts and Fantasies) in 2010, I came away with a fairly exuberant viewpoint on CSP (concentrated solar power, aka solar …

Does All Our Energy Come From the Sun?
A reader just asked me this: Doesn’t all our energy come from the sun? Fossil fuels are old sunlight, and anything else we burn is new sunlight. We have to burn this one way or the other, and that creates …
Concentrated Solar Power – Will It Have Its Day?
Anyone who has written off CSP as a technology whose level cost of energy is doomed to remain hopelessly cost-ineffective needs to know that the Saudis are installing this stuff at a record-setting pace. Why wouldn’t a country sitting on …
