Green and off-grid texts always devote a lot of space to alternative methods of transportation. The reason is that burning a gallon of gasoline supposedly produces 23 pounds of carbon dioxide. Although the math doesn't make a lot of sense (a gallon of gas only weighs 6 pounds), we get the idea. Not to mention that at the time of this writing, gasoline was more than $4 per gallon. Eventually, we simply won't be able to afford our gasoline-powered cars. The automakers are finally paying attention, and today, they are scrambling to develop electric and hybrid vehicles. Their success depends largely on the development of adequate battery technologies, emerging plug-in hybrid electric vehicles (PHEV) technology, and finding a place for biofuels such as eth-anol, biodiesel, biogas, and hydrogen cell technologies. The eventual goal is to develop zero-emissions vehicles that do not burn fossil fuel, but are instead powered by alternative fuels such as hydrogen.

Hybrid and electric cars are still beyond the financial reach of most Americans. The people who need them the most are not going to be the people that get them ... for now. In the meantime, here are some things the average person can do:
