Overview
Chevron is one of the world's leading producers of geothermal energy, a renewable resource that captures the natural power of steam from the earth to generate electricity while producing almost no greenhouse emissions. Chevron's geothermal plants in Indonesia and the Philippines produce enough energy to power millions of homes.
Discover Geothermal
Step 1
Geothermal zones are located in seismically active areas where earthquakes and volcanoes are concentrated.
Step 2
Wells are drilled into productive geothermal zones, releasing a mixture of hot water and steam.
Step 3
Once captured, steam and hot water are separated. The steam is cleaned and sent to the power plant.
Step 4
The separated water is returned to the reservoir, helping to regenerate the steam source.
Step 5
Steam spins a turbine in the power plant, which generates electricity.
Step 6
Electricity from the power plant is transmitted to consumers through the grid.
Step 7
Chevron's geothermal operations generate enough energy to meet the needs of millions of people in Indonesia and the Philippines.

Producing Geothermal Power
Geothermal power is one of the most promising renewable energies on the horizon, and Chevron is leading the way with two plants in Indonesia. Dion Kumboro, a manager at the Darajat geothermal plant in Java, explains how Chevron harnesses the natural resource of steam to meet the growing energy demands of the local population

Geothermal is essentially a renewable source of energy that uses the heat from the earth to generate electricity with almost no greenhouse gas emissions. It is a renewable source of energy. The steam transfers into the condensate in vapor. After its energy is utilized, the condensate is reinjected back into the earth so the cycle of energy is in use.
The clean and renewable energy not only benefits Chevron commercially, but the host country and the local community as well for its energy demand and the revenue it's generating in income through tax and royalties.
As an asset manager I have a direct influence to promote the benefit of geothermal power as a clean and renewable energy to our local stakeholders by working together with them informally through educational programs for local community, or school children here – explaining to them what geothermal is all about.
I feel proud because I work for a company leading in renewable and green energy and the fact that there are only a few companies in the geothermal industry. Chevron also promotes the diversification of energy so that the non-renewable energy in the world can last longer.

Geothermal energy is produced when underground water is heated by molten magma. Steam is released by drilling a well to tap the reservoir.
