Hydrogen Fuel Cell Cars: Worth the Investment? Hydrogen is the most abundant element in the universe‚ but only recently have people been able to harness this resource and turn it into energy. Hydrogen fuel cell cars are one such advancement made in the effort to turn hydrogen gas into electricity. Fuel cells in the car are used to convert hydrogen into an electrical current‚ and thus power the vehicle. Fuel cells convert hydrogen and oxygen into water while producing electricity.

USE ALTERNATIVE FUELS‚ SAVE PLANET EARTH We are all aware of the current state of our environment. Mother Earth is on the brink of total destruction brought about by pollution‚ irresponsible use of resources‚ and the excessive use of conventional fuel such as fossil fuel and nuclear energy. Part of the efforts to save our planet is to shift from using conventional fuels to alternative ones such as wind energy‚ solar‚ tidal‚ wave‚ oceal‚ thermal‚ dendrothermal‚ biogas and biodiesel‚ alcohol

diminishing fossil fuels In 1977‚ the President of the United States of America‚ Jimmy Carter‚ advocated for the use of alternative energy to the American people “because we are now running out of gas and oil‚ we must prepare quickly to strict conservation [of fossil fuels] and to the use of coal and permanent renewable energy sources‚ like solar power.” More than thirty years later his announcement still rings true and is relevant. In fact‚ the current situation of non-renewable fuels is worse than

Differences between fossil fuel and renewable energy One of the great issues facing world in the 21st century is how best to obtain the energy for supporting operations: heat and light‚ transportation‚ production and delivery of goods and services. Fossil fuel supplies nearly 90 percent of the energy‚ according to the U.S. Department of Energy. In contrast‚ only %5 is provided by renewable energy. There are several differences between fossil fuel and renewable energy. Fossil fuel are including: oil
