Primary energy sources are the initial forms of energy available for consumption or conversion before transformation to another form of energy. These sources typically occur naturally and are used to generate electrical power. Depending on the classification, primary energy sources can involve fossil fuels such as coal, natural gas, and oil, as well as low-carbon sources like nuclear, wind and solar energy. These latter options are increasingly favored as they offer sustainable and clean solutions to the need for electricity, having minimal impact on the environment. Nuclear energy, in particular, is a substantial part of the green energy revolution, with many countries considering its expansion due to its efficiency and consistent energy output. These primary energy sources are crucial in the shift towards eco-friendly electricity generation, thus mitigating climate change and reducing air pollution caused by the burning of fossil fuels.
