The solar power: A brief review of renewable energy potential in the world of limited resources

Economic development and sustainability debate often centers on the question of renewable energy. Renewables include hydropower, solar thermal, solar photovoltaic, geothermal power, wind power, biogas, solid and liquid biomass, tidal power, wave power, ocean thermal gradients, as well as organic and inorganic waste material. Sometimes, nuclear energy is also classified as a renewable. Virtually all these renewable sources, with the exception of tidal power and geothermal energy, are directly or indirectly the result of solar insolation, as biomass is largely dependent on sunlight. This article will explore the history and implications of use of solar power at the time of limited natural resources and the threat of climate change.
