Natural resources of renewable energy


The majority of renewable energy technologies are powered by the sun. Earth’s atmosphere system is in equilibrium such that heat radiation into space is equal to incoming solar radiation, the resulting level of energy within the Earth-Atmosphere system can roughly be described as the Earth's "climate. Energy is dissipated around the globe in the form of winds and ocean currents. Wave motion may play a role in the process of transferring mechanical energy between the atmosphere and the ocean through wind stress. Solar energy is also responsible for this distribution.
Renewable energy flows involve natural phenomena such as sunlight, wind, tides, geothermal heat all of these are producers of renewable energy.
"Renewable energy is derived from natural processes that are replenished constantly. Renewable energy in its various forms is derived directly from the sun, or from heat generated deep within the earth. Thus renewable energy is generated from solar, wind, ocean, hydro power, biomass, geothermal resources, and biofuels along hydrogen derived from renewable resources.
