Renewable energy resources are natural energy carriers, constantly renewed by natural processes.
Renewable energy resources are based on the use of:
energy sources: solar radiation, energy of wind, rivers, seas and oceans, the internal heat of the earth, water, air;
energy of the natural movement of air, water flows and the naturally occurring temperature gradients and the density difference;
energy of biomass produced as garden wastes and animal residues, man-made forests and algae;
energy from industrial wastes, municipal solid wastes and sewage sludges;
energy from burning plant biomass, thermal processing of wastes of timber and woodworking industry.
