The world needs a new source of energy, an unspillable source.

What effects will hydrogen fuel cells have on the enviroment?

It is widely believed that an atmospheric increase in the greenhouse gases CO2 has played a significant role in global warming. Even now, CO2 accounts for less than 1/3 of greenhouse gases. Water vapor, on the other hand, accounts for approximately 70% of all greenhouse gases.

The byproduct of hydrogen fuel cells is water vapor. Let’s pretend that every vehicle in America is powered by hydrogen say 10 years from now. That’s a lot of water vapor! What effect would it have?
