The United States, the single largest energy consumer in the world, is also among the largest polluters in the world. Each year, Americans waste energy worth billions of dollars, and a large portion of that waste comes from residential and transportation activities. In recent years global warming has become a cause for concern, as has the imminent peaking of world production of fossil fuels such as petroleum and natural gas. In these circumstances, wasting energy is no longer an option. Policy makers have recommended several mitigation strategies that aim to reduce the usage of fossil fuels by increasing efficiency and expanding the supply of alternatives. On the personal front, individuals can increase efficiency, which in return can give them financial benefits in terms of lower energy bills. There are several actions that can help to save energy in homes and offices. Energy efficient improvements not only make a home more comfortable, but they can also yield long-term financial rewards. The key to achieving these savings is a whole-house energy-efficiency plan. In this approach, you begin by ascertaining which parts of your house use the most energy. A home energy audit helps to pinpoint those areas and points you toward the best measures for cutting usage.
