1PolandCurrently in Poland, 97% of electricity comes from burning coal, and 3% of the energy from hydropower.

2PolandRenewable sources of energy in Poland

A reneweble resource means a resource that can be totally replaced or is always available naturally, or that is practically inexhaustible.

3Polandhydro energy

Hydroelectric power plant on the Vistula.Due to the low-lying area of the country, possibilities of using Polish rivers are not too remarkable. Currently operate here already 127 large power plants and approximately 300 small ones.4Polandsolar energy

Solar energy is a highly regarded and widely used source of energy in many countries around the world, also in Poland.5Poland

Wind energy production in Poland is developing since the early 90s.However the role of wind energy in the Polish energy balance is small, the situation is gradually changing.Wind energy6Polandbiomass energy

In Poland, the vast majority of generation of energy of biomass is based on the production of heat, especially in small, local (often household) power installations.7PolandPoland has very good geothermal conditions, as 80% of the country falls within the 3 geothermal divisions.geothermal energy

8PolandNon-renewable sources of energy in Poland With the increase in world population, resources of our planet diminish. Their exhaustion will lead to huge changes in our lives.

Polandcoal and ligniteCoal is a strategic resource in Poland because it caters to 65%of energy needs of the country. Polish coal and lignite resourcesare among the largest in the world.910Polandpetroleum

Poland is a country poor in petroleum.The main extraction region is Polish Lowlands, where are 42 of 84 proven reserves in the country.11Polandnatural gasIn recent decades, there is an increasing demand for natural gas in the world. Deposits of natural gas are stand-alone or accompanied by deposits of petroleum or coal.

12Polandnuclear energyPoland has no nuclear power plants, but it has been already planned to build them.

13PolandEffects of radiation on human healthAll living organisms on the Earth are threatened by radiation.Under the influence of radiation a number of changes in the human body (living tissue) occur.

14PolandThe diseases, which can manifest themselves at a later date include:- Skin cancer;- Leukemia;- Gastrointestinal disease;- Bone disease;

15PolandThe radiation can be deadly to humans, this is definitely a threat to our species.

16PolandSoon run out of non-renewable energy sources.

What then?
