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.
