Oil

Today’s electric system is almost unrecognizable from the electric system a decade ago. Generation from natural gas and renewables has accelerated to replace the rapid and unprecedented retirement of coal-fired generators. Wind, solar, and geothermal electric generating capacity in the United States has now eclipsed capacities from hydroelectric and nuclear resources combined. Carbon dioxide (CO2) emissions have reached their lowest levels since 1987. Meanwhile, both total generation and electric sales have held relatively steady for 10 years.

California often leads the nation in its efforts to reduce greenhouse gas (GHG) emissions by decreasing the use of fossil fuels. Also important—but often overlooked—is California’s role as an oil producer. While this role has declined, the state still produces about 5 percent of U.S. crude oil, or 0.5 percent of world production.
