Solar energy is a form of renewable energy, in which sunlight is turned into electricity, heat, or other forms of energy we can use is a "carbon-free" energy source that, once built, produces none of the greenhouse gas emissions that are driving climate change. Solar is the fastest-growing energy source in the world, adding 270 terawatt-hours of new electricity

How Is Electricity Generated? Energy Production Explained

Nuclear power plants. In nuclear power plants, nuclear reactions release energy in the form of heat, which is then used to produce steam from water. The steam drives a turbine connected to an electric generator, converting the mechanical energy into electricity. Currently, nuclear power plants are powered by fission reactions (splitting atoms), but scientists are working hard to

Solar power | Definition, Electricity, Renewable Energy, Pros and

Solar power is a form of energy conversion in which sunlight is used to generate electricity. Virtually nonpolluting and abundantly available, solar power stands in stark contrast to the combustion of fossil fuel and has become increasingly attractive to individuals, businesses, and governments on the path to sustainability.

How Solar Cells Work

The solar panels that you see on power stations and satellites are also called photovoltaic (PV) panels, or photovoltaic cells, which as the name implies (photo meaning "light" and voltaic meaning "electricity"), convert sunlight directly into electricity.
