The practical options for energy range from the standard fuels, natural gas, petroleum (or oil), and coal. Fossil fuels are referred to as nonrenewable energy sources because, once used, they are gone. Scientists are exploring the practicality of other sources called renewable energizes. These include sun, wind, geothermal, water, and biomass. The renewable power resources are very important in long range energy planning simply because they will not be depleted.

When a plan is finally formulated it usually looks something such as this; you are going on a diet of some sort and if you're really motivated attempt an exercise program. This makes sense because everybody knows the fewer calories we take in the more fat we could lose. Add jogging a couple of times a week and some sit-up and eventually that rebellious stomach is going to be put in its place.
