Solar power in California has been growing rapidly because of high insolation, community support, and a Renewable Portfolio Standard which requires that 20% of California's electricity come from renewable resources by 2010, and 33% by 2020. Much of this is expected to come from solar power. As of the end of 2011, California had 364 MW of concentrated solar power and 1,564 MW of photovoltaics.
The largest solar power installation in the world is the 354 MW solar thermal SEGS plant, completed in 1991. The Ivanpah Solar Electric Generating System (392 MW), located 40 miles (60 km) southwest of Las Vegas, is the world's largest solar thermal power project currently under construction.
California leads the nation in the total number of homes which have solar panels installed. Many were installed because of the million solar roof initiative. In 2008, the state decided that it was not moving forward fast enough on photovoltaic generation and enacted a feed-in tariff. A feed-in tariff is both the least expensive and the most effective means of increasing solar usage. It is similar to a power purchase agreement, but at a much higher rate. As the industry matures, the tariff is reduced to the retail rate and becomes the same as a power purchase agreement. A feed-in tariff allows investors a guaranteed return on investment - a requirement for development.

Famous quotes containing the words solar, power and/or california:
“Our civilization has decided ... that determining the guilt or innocence of men is a thing too important to be trusted to trained men.... When it wants a library catalogued, or the solar system discovered, or any trifle of that kind, it uses up its specialists. But when it wishes anything done which is really serious, it collects twelve of the ordinary men standing round. The same thing was done, if I remember right, by the Founder of Christianity.”
—Gilbert Keith Chesterton (1874–1936)
“The piety of the Hebrew prophets purges their grossness. The circumcision is an example of the power of poetry to raise the low and offensive.”
—Ralph Waldo Emerson (1803–1882)
“I can’t earn my own living. I could never make anything turn into money. It’s like making fires. A careful assortment of paper, shavings, faggots and kindling nicely tipped with pitch will never light for me. I have never been present when a cigarette butt, extinct, thrown into a damp and isolated spot, started a conflagration in the California woods.”
—Margaret Anderson (1886–1973)
