"The press release (pdf) is dated April 1st, but this is no joke.
Because of California law, PG&E needs to get 20%% of its electricity
from renewable sources (not including big hydro) by 2010, so it has
contracted with Brightsource Energy for 3 new solar-thermal power
plants in the Mojave desert, one of the best spots for solar power in
the world.

"Solar thermal energy is an especially attractive renewable power
source because it is available when needed most in California - during
the peak mid-day summer period," said Fong Wan, vice president of
energy procurement at PG&E. These first three plants will add up to
500 megawatts of capacity, but PG&E has also signed contracts for
options on an additional 400 megawatts, which could bring the total to
900 megawatts."
