THE SCIENCE OF RENEWABLE ENERGY ON GLOBAL WARMING: A REVIEW OF GREENHOUSE GASES EMISSION

Renewable energy sources are key contributors to mitigation of greenhouse gases (GHG) emissions. Moreover, increased atmospheric CO2 concentration is considered as the main factor for global warming. In this paper, specific attention is paid to understanding the life cycle of GHG emissions from a range of renewable energy technologies. Comprehensive reviews for each Renewable Energy technologies were carried out. Data show that the CO2 content is the minimum for renewable energy like offshore wind, wave and tidal, while biomass energy have high greenhouse gases emission. Finally, the primary energy sources such as solar radiation, Wind, tidal and hydro-power are practically infinite on the scale of human needs.
