Energy efficiency means using less energy through better technology to light streets, transport goods and people, and power homes and businesses. Reducing our energy use is one of the most cost-effective and fastest ways to meet our energy needs. And energy efficiency saves money - money that can be invested in schools, job creation, and new infrastructure.

For example, a compact fluorescent light bulb that uses 16 watts of electricity produces as much light as an old fashioned 60 watt bulb, prevents 400 pounds of coal from being burned on the south side of San Antonio to produce electricity, and saves from two to four times its purchase price.

Since fossil fuel power plants generate more than one-third of U.S. global warming emissions, saving energy also reduces pollution. From high tech lighting to energy-efficient building standards to fuel efficient transportation, energy efficiency makes good sense and good cents.
