Alternative fuel sources are being designed to meet rapidly growing challenges that confront individuals and economies around the world. In the United States and other western nations, renewable energy sources can serve to reduce local dependence on foreign energy sources that incur high political risks.
Global concerns include the need to rely on renewable sources of energy to prevent the total depletion of valuable natural resources and the ability to greatly reduce emissions of CO2 and other environmentally harmful substances.

The use of hydrogen is very popular in fuel cell vehicles, including electrics or hybrids.
