Ever increasing economic growth increases the pressures on the environment. Growing demand for energy, land space and other resources have led to an increased strain on traditional energy resources such as fossil fuels. Finding and tapping new reserves for these resources have become an almost insurmountable challenge for the traditional sources of energy. Global warming and environmental instability add to the increasing pressure on non renewable sources of energy.
Green energy refers to forms of energy created from renewable sources such as water, wind and the sun. These methods are becoming increasingly popular as they reduce the pressure and environmental impacts of conventional methods of energy generation and increase a nation’s energy independence.
