US solar installs

Welcome news from the editors at real clear energy, here’s one of their “charticles” tracking US solar installations. Megawatts of solar technology installed went from 100 MW in 2006 to 1000 MW in 2010! Of course that number must be qualified by the efficiency of solar tech, as the editors explain, but this is expected to improve over time. Will we see infinite linear progress in solar energy technology? No. But we can certainly get the cost per kWh down from Forbes’ calculation of 7.7 cents/kWh so that solar is cost competitive with other energy sources.
