1: Solar energy which comprises of radiant heat and light from the sun can be harnessed with some modern technology like photo-voltaic, solar heating, artificial photosynthesis, solar architecture and solar thermal electricity.

2: Solar energy has also another use. By means of photosynthesis, solar energy is converted by green plants into chemical energy which creates the bio mass that makes up the fossil fuels.

3: The oil crisis of 1970 revealed the delicate nature of fossil fuels as a source of energy for the world. As such research in alternative, renewable energy technology like that of solar and wind energy gained momentum.

4: Thermal storage systems can store solar energy in the form of heat by using common materials with high specific heat such as stone, earth and water. Solar energy can be stored also in molten salts.

5: Space missions by various countries use solar energy to power their spaceships.
