The Golden State is set to put in place aggressive renewable power standards. This would give California the most strict standard for renewable energy.
The measure will require that one third of utilities power comes from solar cells, windmills or other alternative energy sources within a time frame of ten years.
Supporters say this will allow for cleaner air and less reliance on foreign oil. Critics say this will hurt state businesses because California's high energy costs will be driven up further.
Governor Jerry Brown is expected to sign a bill into law at a solar plant in the San Francisco Bay area sometime today.
