Nuclear power plants use the process of nuclear fission to generate heat. In this process, the nucleus of an atom is split, releasing a large amount of energy in the form of heat. This heat is used to produce steam, which drives turbines and generates electricity. Nuclear power is considered a low-emission source of electricity, but it comes with challenges related to radioactive waste disposal and safety concerns.
Hydropower involves the use of flowing water (rivers, dams, and reservoirs) to turn turbines and generate electricity. The energy of moving water is converted into mechanical energy, which is then converted into electrical energy. Hydropower is a renewable energy source and has been used for decades to produce electricity.
Geothermal power generation harnesses heat from the Earth’s interior to produce steam, which drives turbines and generates electricity. This method is mainly feasible in regions with high geothermal activity, such as geysers and hot springs.
Biomass power plants burn organic materials like wood, agricultural residues, and other biological matter to produce heat and generate electricity. While biomass is renewable, its environmental impact depends on factors such as sourcing, land use, and emissions.
