The sun has produced energy for billions of years. Solar energy is the sun’s rays (solar radiation) that reach the earth. Solar energy can be converted into other forms of energy‚ such as heat and electricity. In the 1830s‚ the British astronomer John Herschel used a solar thermal collector box (a device that absorbs sunlight to collect heat) to cook food during an expedition to Africa. Today‚ people use the sun’s energy for lots of things. Solar energy can be converted to thermal (or heat) energy

This has led to the idea of setting up a space solar power station (SSPS)
