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.

What are the different types of renewable energy?

What is renewable energy? Renewable energy is energy that comes from a source that won''t run out. They are natural and self-replenishing, and usually have a low- or zero-carbon footprint. Examples of renewable energy sources include wind power, solar power, bioenergy (organic matter burned as a fuel) and hydroelectric, including tidal energy.

Solar energy

About 125 GW of new solar PV capacity was added in 2020, the largest capacity addition of any renewable energy source. Solar PV is highly modular and ranges in size from small solar home kits and rooftop installations of 3-20 kW capacity, right up to systems with capacity in the hundreds of megawatts. It has democratised electricity production.
