In Polish conditions heat is produced from solar energy using solar collectors as well as from low temperature heat of soil and water using heat pumps, from geothermal energy or from fired or co-fired biomass.
Mechanical energy is obtained from wind (grinding mills, windmills, simple intermediate pumping stations) or from water (sawmills, water-mills).
From seeds of oily plants it is possible to produce (by chemical processes) biofuels, which are added to liquid fuels or may be used directly in engines of a special parameters.
