Renewable sources of energy - an energy source which uses is not associated with their long-term deficits, because their supply is renewed in a short time. Such sources are: wind, sunlight, rain, tides, waves and geothermal.Renewable energy sources meet about 8,5% of the energy needs of humanity, of which 6,5% meets hydropower. Since the beginning of the twenty-first century global investment in renewable energy sources are growing in an exponential way.
SOLAR ENERGY- the type of industry, dealing with the use of solar energy classified as renewable energy sources.
BIOMASS- Through the photosynthesis, solar energy is accumulated in the biomass plant organisms initially, later in the animal food chain. The energy contained in the biomass can be used for human purposes. This involves the processing of other forms of energy by biomass burning or incineration degradation products. As a result of the heat of combustion is obtained, which can be processed into other forms of energy, such as electricity.
WIND ENERGY- the kinetic energy of moving air masses. It is processed into electricity using wind turbines, as well as mechanical energy used in wind turbines and wind pumps and as a prime mover in sailing yacht.

Geothermal energy - heat the rocks located inside the Earth. It is collected by drilling, which is cold pressed and received hot water after heat exchange with the hot rocks. Geothermal energy is used in 64 countries. It is used in several places in Poland especially in spa resorts, pools etc

Hydropower - uses economically mechanical energy of running water. Today, hydropower is usually processed into electricity. It can also be used directly to drive the machines - there are many solutions in which flowing water drives a turbine or water wheel.
Solina - hydropower energy in Poland
Wind energy is uncontrollable and this feature makes difficult the development of wind power plants. The most favourable conditions for wind energy in Poland are in the northern and eastern parts of the country. In those regions windmills are located. Currently in Poland there are 619 wind installations working of the total capacity about 2188 MW. A big development of the electricity production based on wind energy is foreseen in the nearest future. According to governmental sourceswith the total capacity of 6670 MW in year 2020.

Reserves of hydroenergy in Poland are not high, as they are estimated to about 50 PJ per year and are the lowest reserves of all renewable energy sources in Poland. Nevertheless the reserves are relatively well developed.

Although the reserves of solar energy in Poland are relatively high, their utilisation is not easy because of high irregularity of solar radiation. Solar energy is used to small extend in solar and photovoltaic installations.
SOLAR ENERGY
Poland’s potential and reserves of geothermal energy are relatively high. The perspective reserves of geothermal waters occur in many regions of Poland. Majority of the water is characterised by low enthalpy and high mineralization.
GEOTHERMAL ENERGY
The biomass can be divided into: Solid biofuels Liquid biofuels
Gaseous biofuels Biofuels such as wood and straw are used for the
heat production purposes, mainly in individual stoves. It is estimated that the total capacity of installed stoves for wood firing reaches 6100 MJ/s. In Poland about 185 stoves for straw firing is exploited of the total capacity 95 MJ/s.
BIOMASS ENERGY
In our province 27 commons got over 140 million zloty to carry out the project which is supposed to help our province in ecological action and life.
We get quite a lot of sun in our region, so investments in solar panels are cost-effective, installation of solar panels is worth about 15 thousands zloty and thanks to the UE grants people pay only 2 or 2,5 thousands zloty.
In our province renewable sources of energy creates new opportunities in terms of new job s for regions where is high rate of unemployment
