According to the US Energy Information Agency, ten percent of the energy produced here in America is now renewable. Which means for now clean energy sources are only a fraction of the countries overall power supply.

But the available options for clean, green energy usage are growing. More than 850 utilities across the United States now offer customers a choice to buy power from sources like wind, solar, and geothermal. And 29 states plus the District of Columbia have renewable energy requirements for energy providers.

The Department of Energy's National Renewable Energy Laboratory found a 20% increase in green power sales in 2008. More than 600,000 utility customers nationally participate in green power programs.

According to a recent study of Department of Energy numbers, a national renewable energy standard of 25 percent by 2025 would save Americans nearly $100 billion in electricity costs, stretching across all regions of the country .
