• Geothermal energy is created by the heat of the earth. It generates reliable power and emits almost no greenhouse gases.

• Chevron's geothermal operations at the Salak Field in Indonesia produce steam to generate reliable power and almost no greenhouse emissions.

• This is how it works: When groundwater seeps below the earth's surface near a dormant volcano, the water is heated by reservoirs of molten rock,usually at depths of up to 9,800 feet (3,000 m). Wells similar to those used to produce crude oil and natural gas are drilled to recover the water. Oncecaptured, steam and hot water are separated. The steam is cleaned and sent to the power plant. The separated water is returned to the reservoir,helping to regenerate the steam source.

• Only a small group of places around the globe provide the special conditions needed to generate geothermal energy. At these locations, deepfractures in the earth's crust allow the molten rock to surge close enough to the earth's surface to heat water underground.

• What Are the Benefits?

• In addition to providing clean, renewable power, geothermal energy has significant environmental advantages. Geothermal emissions contain few

chemical pollutants and little waste—

they consist mostly of water, which is reinjected into the earth.• Geothermal energy is a reliable source of power that can reduce the need for imported fuels for power generation. It's also renewable because it is

based on a practically limitless resource—natural heat within the earth.

• The electricity produced by our geothermal power operations is sold to local power grids, providing clean energy to fuel the growth of some of themost rapidly expanding economies in the world.

• What Chevron Is Doing

• Chevron is the world's largest producer of geothermal energy.

• Chevron began geothermal operations during the 1960s in the western United States by pioneering the development of The Geysers, north of SanFrancisco, California. In the 1970s, two discoveries in the Philippines led to the development of the Tiwi and Makiling-Banahaw (Mak-Ban)geothermal projects on Luzon. We discovered the Salak and Darajat fields on Java in Indonesia during the 1980s and began commercial production inthe 1990s.

• Chevron's geothermal operations from the four projects in Indonesia and the Philippines currently have the capacity to produce 1,273 megawatts of

renewable geothermal energy, enough to meet the needs of millions of people in those countries. In 2010, we began assessing prospects in bothcountries that could lead to more geothermal energy production.

• Geothermal resources represent significant untapped energy. As Chevron continues to pursue geothermal opportunities, it is at the forefront of bringing this clean, renewable energy to our communities.

• Renewable Energy, Technology and Other Businesses

• Renewable Energy

• Strategy: Invest in renewable energy technologies and capture profitable positions.

• In 2007, we forged research alliances with Texas A&M University and the National Renewable Energy Laboratoryto develop cellulosic biofuels from nonfood sources. In another collaboration, the Alameda-Contra Costa TransitDistrict in California is testing a biodiesel fuel blend and a gas-to-liquids diesel that Chevron is providing for a fleetof buses operating in the San Francisco Bay Area.

• Additionally, Chevron expanded geothermal production in Indonesia with the startup of the 110-megawatt DarajatIII geothermal power plant in West Java. Chevron is the world's largest producer of geothermal energy (seeDeveloping Renewable Energy).

• Our Chevron Energy Solutions subsidiary is helping internal and external customers increase their energyefficiency and use renewable sources of energy. One solar project for a California university is expected to supply20 percent of the school's annual power needs and lower its utility costs.

• Technology

• Chevron's three technology companies— Energy Technology, Technology Ventures and Information Technology— support our core businesses and enable our most promising future opportunities (see Putting Technology toWork). In 2007, we established new technology centers in Australia and Scotland to provide strategic research,development and technical services to our global businesses. We also have centers in California and Texas.

• Other Businesses

• Our 50-50 joint venture Chevron Phillips Chemical Company LLC is one of the world's leading manufacturers of petrochemicals. Chevron Oronite markets more than 500 performance-enhancing products and supplies one-fourth of the world's fuel and lubricant additives. Other businesses include mining, pipeline, power generationand shipping
