Final Exam Question #3

A renewable resource is a resource replenished by its natural process at a rate equal to or faster than its rate of being used by humans or other things that use it. In other words a renewable resource is a resource that is not in danger of ever being used in excess of its long term availability. Examples of some renewable resources are solar power which comes from the sun have its energy stored in things such as water, wind power which comes from the winds caused by the heating and cooling of the earth's surface which causes the air to move and to turn turbines to make electricity, hydro power which comes from moving water to turn turbines to make electricity, and geothermal power which is the heat coming from the earth itself through the ground. All of these will be better for the environment and will have little to no pollution and are pretty much never going to be gone. Unless the earth loses its atmosphere then we will lose all wind and we will not be able to use that as a source of energy. The cost of these power sources are less than 5 cents per kilowatt hour. Another benefit is that they are friendly on the environment and do not cause pollution.

A non-renewable resource is a resource that can not regenerated, re-grown, or re-made at a rate equal to or faster than its rate of consumption. There is only a fixed amount of these resources and when they are gone they are gone. Examples of some non-renewable resources are called fossil fuels which include petroleum, coal, and natural gas. One that is not considered a fossil fuel is nuclear powered energy. All these can be burned to make energy and to heat water to make turbines turn to make electricity. Oil is becoming even more expensive as time goes on today on the stock market the price per barrel opened at $138. Soon it won't matter what the price is because there will not be any left.
