Solar energy is energy from the Sun in the form of heat and light. This energy drives the climate and weather and supports virtually all life on Earth. Heat and light from the Sun, along with secondary solar resources such as wind and wave power, hydroelectricity and biomass, account for over 99.9% of the available flow of renewable energy on Earth.

The goal of President Bush's Solar America Initiative is to achieve cost-competitiveness for solar technologies across all market sectors by 2015. DOE is working to accomplish this goal through public-private partnerships with industry, universities, national laboratories, state municipalities, and/or nongovernmental organizations. When federal solar energy research began in the 1970s, in response to rising oil prices, the cost of electricity from solar resources was about $2.00 per kilowatt-hour (kWh). Technological advances during the last two decades have reduced solar electricity costs by more than 90 percent, opening up new markets for solar energy.
