The document discusses different types of power plants in Pakistan. It describes five main types: thermal power plants, hydropower plants, wind power plants, solar power plants, and nuclear power plants. Thermal power plants generate electricity by heating water into steam to spin turbines connected to generators. Hydropower plants use the gravitational force of falling or flowing water through dams to generate electricity. Wind power plants convert kinetic energy from wind into electrical energy using wind turbines. Solar power plants transform solar energy into electricity using solar cells or by focusing light to power engines. Nuclear power plants derive power from controlled nuclear fission to heat water and spin turbines.
