17.8 The Amount of Electricity Generated in Total
on the Background of Renewable Energy Sources
Electricity is currently the most universal and easy to use a form of energy, without
which it is difficult to imagine everyday existence. We are completely dependent on
it, even though we have been using it for over 150 years. The majority of energy in
Poland is produced in coal-fired power plants burning hard coal and lignite; small
investments are carried out in the use of gas turbines fed with natural gas. Unfortunately, these are objects that use fossil fuels that emit huge amounts of CO 2 and
