You must have heard that LED flashlights are increasingly being used in homes. LED light bulbs are becoming popular for normal lighting as well. They are efficient and very cost effective. LED (Light Emitting Diode) light initially began its life as a small red light on various products; today, it is already doing much more than that. Other than the flashlights with LED, you can also have LED camping lanterns, LED head lamps, LED lanterns, and solar LED lanterns, among others.
Using Solar Power For Homes
Solar energy was used in ancient times for heating houses. It was after the discovery of the photoelectric effect and the invention of steam engine powered by solar energy that people started thinking about using solar power for running simple domestic machines, besides using it for heating purposes.

Features of Solar energy in India.
India is both densely populated and has high solar insulation, providing an ideal combination for solar energy in India. Much of the country does not have an electrical grid, so one of the first applications of solar energy has been for water pumping, to begin replacing India's four to five million diesel powered water pumps, each consuming about 3.5 kilowatts, and off-grid lighting. Some large projects have been proposed, and a 35,000 km² area of the Thar Desert has been set aside for solar energy projects, sufficient to generate 700 to 2,100 gigawatts.
