Introduction • Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves, and geothermal heat. • Renewable energy resources exist over wide geographical areas, in contrast to other energy sources, which are concentrated in a limited number of countries. Rapid deployment of renewable energy and energy efficiency is resulting in significant energy security, climate change mitigation, and economic benefits • Renewable energy resources and significant opportunities for energy efficiency exist over wide geographical areas, in contrast to other energy sources, which are concentrated in a limited number of countries.
Renewable Energy Main Form of Renewable Energy • Wind Energy. • Hydro Energy. • Solar Energy. • Biomass Energy. • Geothermal Energy.
Wind Energy • Wind is caused by huge convection currents in the Earth's atmosphere, driven by heat energy from the Sun. This means as long as the sun shines, there will be wind. • wind energy is believed to be five times total current global energy production, or 40 times current electricity demand. • This could require large amounts of land to be used for wind turbines, particularly in areas of higher wind resources. Offshore resources experience wind speeds of ~90% greater than that of land.
