Solar Water Heating
How California Can Reduce Its Dependence on Natural Gas

Executive Summary

Solar hot water systems capture energy from the sun to heat water for homes and businesses, thereby displacing the use of natural gas, or in some cases electricity, with free and limitless solar energy. Solar Water Heating finds that increasing the use of solar hot water heaters could save California 1.2 billion therms of natural gas a year, the equivalent of 24 percent of all gas use in homes. To prevent global warming pollution, reduce dependence on imported fuel, and ease the price of natural gas, California should act now by jumpstarting a mainstream market for solar hot water.
