Green Energy

Green energy is power that is derived from natural energy flows, such as solar radiation, whereby there are no harmful, toxic, or other emissions that are deleterious to the environment. Green energy sources are ultimately more sustainable than fossil fuel–based power generation, as they are harnessing “ambient” energy and, as such, cannot “run out.” It must be noted that although green energy technologies represent an improvement on the technologies they supersede, no source of power is free of environmental impact.

Although green energy is usually used in the context of electricity generation, “green energy” can in some contexts of application be used to provide mechanical drive directly and, in some cases, thermal energy.

Green power refers to renewable resources, including solar technologies. The Sandia National Laboratory presented ...
