Five percent of the energy federal agencies use this year must come from renewable sources such as wind, solar and biomass, under the 2005 Energy Policy Act. That’s up from 3 percent in 2009.
To help agencies get there, the Environmental Protection Agency has a nifty mapping tool on its website that lists available green power resources by state and links to the utility companies’ websites.
The nation’s capital, for instance, has six options that include wind or landfill gas in the energy mix. California offers a dozen green power alternatives, including energy generated by wind, solar, water and landfill gas.
The tool also lists nationally available renewable energy certificates (RECs) that agencies can purchase to help them offset the use of traditional carbon-based power.
