What is Solar Energy? (Definition, Pros, Cons and Examples)

Solar energy is heat and radiant light from the Sun that can be harnessed with technologies such as solar power (which is used to generate electricity) and solar thermal energy (which is used for applications such as water heating). As a renewable and clean energy resource, solar can be used as a replacement for fossil fuels, producing heat, creating chemical reactions and

Solar is now ''cheapest electricity in history'', confirms IEA
