renewable energy and emerging technology

alternative and renewable energy sources play a role in meeting future energy demand

"For the latest figures, view the 2016 Supplement to the Annual Report (4.7 MB)."

Chevron continues to be committed to understanding and evaluating the economic viability of investments in renewable energy. We pursue renewable energy technologies that leverage our company’s strengths and that can be deployed with competitive economic returns. These technologies include geothermal energy, advanced biofuels, wind power and solar energy, in addition to energy efficiency technologies. We conduct internal research and collaborate with governments, businesses and academia in researching and developing alternative and renewable energy sources. Through these partnerships, we share information and help to advance technology that can lead to more renewable energy for future generations.

geothermal energy

Chevron is one of the world's leading producers of geothermal energy, which is created by the heat of the earth, and is a clean, renewable resource with relatively low greenhouse gas emissions. In Indonesia and the Philippines, we supply enough geothermal energy to meet the needs of millions of people in these countries. The technologies and processes used in geothermal production have much in common with those for oil and gas. Chevron uses its experience in reservoir characterization and safe, efficient drilling to produce this renewable resource.

Chevron Geothermal Indonesia, Ltd., manages two large geothermal projects in Indonesia—Darajat and Salak, both on the island of Java. The output from our Darajat and Salak geothermal operations provides steam to two power plants with a total capacity of 647 megawatts. In 2006, the Darajat III unit was approved by the United Nations (UN) as a Clean Development Mechanism (CDM) project, a market-based instrument of the UN's Kyoto Protocol to encourage implementation of cost-effective greenhouse gas reductions. At the time of registration, Darajat III was the largest geothermal energy project registered under the CDM program. The Darajat III unit continues to help Indonesia avoid emissions of over 650,000 metric tons of CO2 equivalents per year.

In the Philippines, the Philippines Geothermal Production Company (in which Chevron has a 40 percent interest) produces steam energy for the Tiwi and Mak-Ban geothermal power plants in southern Luzon, which have a combined capacity of 692 megawatts.

Chevron is also an investor in the John L. Featherstone (formerly Hudson Ranch Power I) geothermal plant in the Salton Sea geothermal field of California. This 49.9-megawatt capacity project is the first stand-alone geothermal power generation project to have been developed, permitted and built in the last 20 years in California's Salton Sea geothermal resource area.

advanced solar technologies

Photovoltaic cells made from silicon alloys can convert sunlight into other forms of energy, such as heat and electricity. Steam generators using thermal collectors to heat water sometimes convert even larger amounts of solar energy into electricity. Solar power can help alleviate capacity problems on local utility grids and reduce greenhouse gas emissions by decreasing the use of electricity from power plants that use fossil fuels.

Chevron's photovoltaic projects at Questa, New Mexico, and in the San Joaquin Valley, California, continue to test and evaluate solar technologies. The installation at Questa, for example, uses lenses to focus sunlight onto three-layer solar cells. Since its inception in April 2011 through the end of 2015, the Questa project has produced 7.2 million kilowatt-hours of renewable energy.

Project Brightfield, a demonstration of solar energy technologies in Bakersfield, California, has evaluated seven photovoltaic technologies to help determine the potential application of renewable power at other company-owned facilities. The project currently operates on the site of a former Chevron refinery. 

Chevron has also invested in five joint-venture photovoltaic solar facilities in California, Arizona and Texas, which, at peak capacity, generate a combined 73 megawatts of renewable energy.

wind power

Our Casper Wind Farm, commissioned in 2009, has turned a former refinery site near Casper, Wyoming, into an 11-turbine, 16.5 megawatt capacity wind farm, enough to power approximately 4,400 homes.


Biofuels are one of Chevron’s renewable energy focus areas. We believe that biofuels that complement conventional transportation fuels will play an increasing role in meeting the world's growing energy needs.

Almost all of the gasoline Chevron sells in the United States contains ethanol, a conventional biofuel derived from edible sugars and starches. We also conduct research on advanced biofuels, but limit our choice of raw materials to those that do not materially affect food or feed supplies.
