The National Renewable Energy Laboratory (NREL) is a research facility that is part of the United States Department Of Energy (DOE). The Research and Development expertise are with Renewable Electricity, Renewable Fuels, Integrated Energy Systems and Strategic Energy Analysis. These technologies are distributed by the Technology Transfer Office of the NREL whose main function is to introduce renewable energy and energy efficiency technologies to the public and the marketplace. These technologies can then be transferred into commercial products and businesses.

No discussion of renewable energy would be complete without paying some attention to the bystanders sometimes left out of the discussions: geothermal and hydro electric energy.

Although they are not considered to be of serious impact at this stage, they do present energy options for localized communities who might wish to subsidize their power grid with another source of readily available energy that lessens their dependence on the main form of energy.

Geothermal energy is used for electrical power production in 21 countries, and supplies significant amounts of electricity to countries such as the Philippines, where 27 percent of electricity derives from geothermal sources.

Geothermal energy is a mainstay of the Icelandic economy, and is also heavily exploited in the United States, with 43 geothermal plants. Geothermal energy is used for electric power generation and direct utilization in the United States.

Even so, this worldwide use represents only a fraction of the potential power that could be generated from geothermal resources. Geothermal energy is generally a highly localized resource, and the processes used to extract energy move at a much higher rate than the processes that restore energy into the geothermal environment.
