Jewish Energy Guide: Green Your Home

Summary: David Krantz, president and chairperson of the Green Zionist Alliance, shows how easy it is to go green at home. He offers up some interesting tips to help you get started!

Compact fluorescent light bulbs use about a quarter of the energy of their traditional incandescent lighting brethren. Compact fluorescents last for years, and although they contain mercury, it’s still less than the amount of mercury released into the atmosphere by producing the extra amount of energy needed to power conventional bulbs. But the best option may be LED bulbs. They don’t use mercury and they only use about a quarter of the energy of compact fluorescents — or about 1/16th of the energy of conventional bulbs.

LEDs also last much longer: One incandescent can last about 1,000 hours, or a few months at normal usage. One fluorescent can last about 8,000 hours, or a few years at normal usage. But one LED can last about 50,000 hours, or about 25 to 30 years at normal usage.
