What is Renewable Energy?
Renewable Energy (RE) resources are regarded as the energy resources that do not have an upper limit on the total quantity which can be used, are renewed on a regular basis, and whose renewal rate is so rapid that they are considered as available over an indefinite period of time. These include solar, wind, biomass, geothermal, hydro and ocean energy, and other emerging energy sources using new technologies such as fuel cells and hydrogen fuels.
RE systems refer to energy systems, which use RE resources applying various energy conversion and/or utilization technologies.
