Solar energy is a very important energy source. It is the ultimate source for all living beings on earth. It provides energy to plants for photosynthesis. These plants form the first level in a food chain and so provide all beings with food, directly or indirectly.

This solar energy is used by our body to form vitamin D and keep us healthy.

Science has come a long way and solar energy technology also matured. We can now harness the sun’s gift in solar heating and solar lighting devices. These are very simplistic but effective machines and help us keep a cleaner and greener mother earth.
