The most crucial factor influencing economic development and social well-being, as well as resulting in the mitigation of the effects of social poverty is electricity and its availability. As a result, a given country?s growing economy generates an increasingly higher demand for energy. Even though the generation of electricity in the Polish power industry is still primarily based on fossil fuels, there is a visible increase in energy produced from renewable sources. In 2016, in Poland the share of renewable energ...
