They form the foundation of global energy systems, supplying power for electricity generation, transportation, industry, and heating.
Major categories include fossil fuels—such as coal, petroleum, and natural gas—which are derived from ancient organic
Renewable primary energy sources, like solar radiation, wind, hydropower, and biomass, are replenished naturally and have
Nuclear energy, derived from uranium fission, provides large-scale baseload power with low greenhouse gas emissions but
The transition toward cleaner primary energy sources is a key global challenge, balancing energy security with
