Long term, the world must develop energy in all its potential forms — from crude oil and natural gas to renewable and unconventional sources of energy. Chevron is working on all fronts. We are the world's largest producer of geothermal energy, with operations in Indonesia and the Philippines. We also are forging alliances to develop affordable energy from other renewable sources, including solar and fuel from nonfood plant sources. In California's San Joaquin Valley, we are powering some of our oil field operations from this solar facility located near Bakersfield. We also are exploring safe, cost-effective technologies to develop new supplies of unconventional energy from oil sands and oil shale.
