Solar expected to make up 40 percent of PG&E's renewable portfolio by 2020 | Développement durable et efficacité énergétique | Scoop.it
Solar power, which makes up a tiny part of Californias overall energy mix, will account for the biggest piece of the states renewable energy pie by the end of the decade, according to the states largest utilities.

Last year, Pacific Gas & Electric got most of its renewable energy from wind, bioenergy, geothermal and small hydropower dams. Solar accounted for about 1 percent. But that mix is quickly changing, and by 2020, the San Francisco-based utility expects solar to account for 40 percent of its renewable portfolio.
California's aggressive "Renewable Portfolio Standard" law requires utilities to purchase 33 percent of their electricity from renewable sources by 2020. Bioenergy, geothermal, solar, wind, wave and tidal power and small hydroelectric dams -- which cause less harm to the environment than large hydro dams -- all count toward meeting the law...
But solar is the fastest-growing piece of renewable portfolios, driven by federal stimulus funding for large solar power plants, a drop in solar panel prices and a boom in the number of developers competing for long-term utility contracts in California...
