What kind of energy is generally used by persons at home?Can you suggest cheaper sources of
lighting in homes?

The consumption of energy for domestic purposes heavily depends upon oil and coal as sources of energy. A new and advanced fighting technology is Compact Fluorescent Lamp (CFL) which is more efficient alternative to domestic energy consumption. According to the Bureau of Energy Efficiency (BEE), the Compact Fluorescent Lamps (CFLs) consume 80% less power as compared to ordinary bulbs. Solar energy could also be generated for domestic use. Biogas can be used for cooking.
Even though new and cheaper alternatives of sources of energy are being tapped, most public utilities encourage the smaller changes that the consumer can make to lessen the pressure on power crisis.
