Power sector is considered the main author of environment pollution. Therefore the changes in this sector towards limitation of environmental harms are symptoms of pro-ecological policy of the world communities.
From renewable energy sources not only electricity but also heat and mechanical energy are produced.
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. To a large extend Poland is an agricultural country so there are there a good conditions for development of biofuels production.
Renewable energy is usually applied in Poland in a small scale, especially in individual houses, in settlements, housing estates and in small towns as dispersed energy production as well as in cooperation with traditional energy production.
The development of renewable energy sources utilisation has to be subsidised for many years with the aid of different incentives and supporting systems, depending on financial possibilities of particular countries. …
Electricity production in Poland, as well as in many other European Union countries, is based on big producers that use for electricity production fossil fuels or nuclear energy. Growing consciousness of the environmental harms caused by conventional power sector entails that more and more considerations is paid to technologies of electricity production based on renewable energy sources such as wind, sun, biomass, geothermal energy. The renewable energy sources are not utilised intensively enough to cover growing demand for electricity all over the World. The additional aspect that restricts the development of renewable energy sources is high costs of energy production. But one of more important criteria of further development of nations in nearest decades becomes the limitation of environment degradation caused by civilising progress.
