There are certain things that are necessary, and there are certain things that are not as important.

Much electrical power is generated by the burning of fossil fuels and growth is putting a serious strain on the supply. Every watt saved by every person can help with this problem. This saving not only will be felt in your wallet, but also in the very air you breathe.
