Germany produces energy from several sources including coal, nuclear, natural gas, and renewable resources like wind, hydroelectric, solar, and biomass. Coal produces around 49% of Germany's electricity but emits harmful gases. Nuclear produces 30% but has risks of radiation. Natural gas produces 8% and also emits gases, though less than coal. Renewables currently produce around 10% of Germany's electricity, with a goal of powering the country completely with renewables, though developing the necessary technologies poses challenges. The industries, transportation, commerce, and households in Germany each consume significant amounts of electricity annually, totaling around 1907 PJ.
