Renewable sources of Energy -Poland

2. Hydropower - economically used mechanical
energy of flowing water. Today, hydropower is
usually processed into electricity.

3. Geothermal energy - the thermal energy of the rocks
located in the interior of the Earth, known to renewable
energy sources. Is charged for using wells to which cold
water is forced and received hot after heat exchange
with the hot rocks. It also serves as a natural source of
heat in the thermal baths.

4. Solar Energy - industry in dealing with the use of solar
energy is classified as renewable energy sources. Since
the beginning of the twenty-first century is growing at
about 40% per year. In 2013, the total installed capacity of
solar cells was 139 GW (an increase of 36.8% compared
to 2012) and they meet the 0.5% of global electricity
demand.

5. Wind energy - kinetic energy of moving air masses, known to
renewable energy sources. Is converted into electricity using
wind turbines, as well as mechanical energy used in windmills
and wind pumps, as well as the prime mover in sailboats.

6. Biomass - means the biodegradable fraction of products, waste and residues
from agriculture (including substances of plant and animal), forestry and related
industries including fisheries and aquaculture, as well as biogas and the
biodegradable fraction of industrial and municipal waste.

7. OTEC - the technology to recover the thermal energy stored in the
oceans, and carefully use the difference in temperature between the
colder waters of the deep and warmer surface water. For this purpose, a
heat engine that converts thermal energy (heat) in mechanical or
electrical energy.
