million tons per year and 60 million tons of the greenhouse gas carbon dioxide would be

eliminated. (Fuel Cells 2000) This shows that fuel cells are environmentally friendly

because they would eliminate 60 million tons of harmful gas. Without that harmful gas

plants will live longer, supplying people with cleaner air. If we invest our time and money

in these great machines they will provide us with a very environmentally safe form of

energy.

Fuel cells are reliable because they run on hydrogen and we will have hydrogen

forever. By never running out of hydrogen fuel cells are the perfect energy source. Fuel

cells are very reliable because they will always have fuel to run on. Fuel cells are very

reliable because they have no moving parts, which decreases the chances of parts breaking.

In cars, fuel cells can go 280 miles without refueling. This shows their reliability because

they can go a long way without having to worry about refueling. The less fueling you

have to do makes the car more reliable.

This shows why fuel cells are environmentally friendly and reliable.

Conclusion.

Fuel cells are a good energy source because they are environmentally friendly and

reliable despite being expensive. You might be saying to yourself ” So what?”. If we

don’t find an energy source that we can use in the future when we run out of coal to burn.

One day one of our most treasured luxuries, electricity, could be gone if we don’t develop

a new way to produce it. Fuel cells are the perfect source from which to produce

electricity because they will always run when there is fuel, they don’t pollute, they have no

moving parts, they don’t make noise, and they are built to last twenty years. Fuel cells

power plants have an efficiency rate of 80 percent. They are twice as efficient as a typical

oil or coal fired plant. If we keep the planet free of destructive exhaust fumes, which

cause ozone depletion, we would have cleaner air to breathe. We also wouldn’t have to

worry about oil tankers spilling millions of gallons of oil in the oceans, causing harm and

death to millions of ocean plants and fish. If we take care of the earth now, we will have

more natural resources such as trees, water, and animals, later. If we find ways to

conserve oil and coal now we will be able to ration it out for a very long time but if we
