The use of fuel cells can significantly diminish our dependency on foreign oil. Since fuel cells make energy electrochemically and do not burn fuel like conventional combustion systems, they are much more efficient. Admittedly, some fuel cells need fossil fuels to start their functions; most residential systems run partially off of natural gas.
If just 20% of the cars in America used fuel cells, we could cut oil imports by 1.5 million barrels per day. This is $44 billion per year that could remain in the country!
