export and harvest nonrenewable resources such as crude oil‚ coal and nuclear energy. People of the world depend on these resources to survive from day to day‚ either putting gas into your vehicle to get to work or producing coal to run our electricity. While most of these resources take thousands of years to form they cannot be replaced as fast as they are being consumed. We as consumers need to reduce our dependency on these non renewable resources. When producing crude oil in the world we are talking

sparing the energy. Cities must be planned in such a way that the commuting distance is minimized. In industry many things could be done to reduce waste of energy or to economize energy. The maintenance may be tightened; waste heat must be utilized properly. If systems arc streamlined‚ economy in fuel could be obtained. Instead of using materials requiring higher energy‚ those which require lower energy can be used. By effecting minor changes in the existing plants‚ economy in energy could be achieved
