In addition to developing alternative sources of energy supplies can be extended by the conservation of currently available resources. There are three types of possible energy conservation practices may be described. The first type is CURTAILMENT, that is, doing without-for example closing factories to reduce the amount of power consumed or cutting back on travel to reduce the amount of gasoline burned. The second type is OVERHAUL. In here we can conserve energy by changing the way people live and the way goods and services are produced. Examples of it are slowing further suburbanization of society, using less energy-intensive materials in production processes, and also decreasing the amount of energy consumed by certain products such as automobiles. And lastly, the third type involves more efficient use of energy. This type of energy conservation focuses in adjusting to a higher energy costs. Examples investing in cars that go farther per unit of fuel, capturing waste heat in factories and reusing it, and also insulating houses. This third option requires less drastic changes in lifestyle, so governments and societies most commonly adopt it over the two options.
