environment. Environmental impact is very important because if you don’t respect the

earth now you won’t have any resources later. Without natural resources we won’t be able

to live. If we keep letting carbon dioxide go into the atmosphere and kill trees and other

plants we will die of carbon dioxide poison. We will also continue global warming.

Electricity is a good example of environmental friendliness because it doesn’t have any

harmful waste products.

Reliability is a good criterion to use when evaluating an energy source. Reliability

is how well you can depend or trust something. Reliability is very important because it is

often in crisis or when we need something the most that it is unavailable or doesn’t work.

In an emergency situation reliability is very important because it can save lives. When

your power goes out you want a reliable flashlight, or when your driving down a deserted

highway you want reliable tires so you don’t get a flat. Therefore reliability is a very

important criterion to use when analyzing an energy source. Solar power is reliable

because the sun comes up every day. It is a fact that sun will come up everyday.

These two criteria are very important when evaluating an energy source.

Section III.

In this section you will be told how the criteria apply to the energy source. Fuel

cells are a good energy source because they are environmentally friendly and very reliable

despite being expensive.

Fuel cells are environmentally friendly because their waste product is a little heat

and water vapor. This shows environmental friendliness because they do not pollute the

earth. By not polluting they don’t kill plants, which supply people with oxygen. If you

take care of the environment now it will help you later. Fuel cells are environmentally

friendly because if just 20 percent of cars used fuel cells, we would cut oil imports by 1.5

million barrels of oil every day. (Fuel Cells 2000) By cutting that many barrels of oil every

day you would not only save enormous amounts of oil, you would also help the

environment. By not burning 1.5 million barrels of oil you would not harm the

environment as much. Big cities would have much less smog if fuel cell-powered cars

were used. The U.S. Department of Energy projects that if a mere 10 percent of
