When looking at alternative enegry sources three things must be considered. Production, Storage and **Distribution.
**
Oil- you know the problems.

Bio-fuels  -basicly, it takes a gallon of oil to make a gallon of ethanol. The water content makes the liquid itself extremely hyper corrosive. Tanks and pipes have to be replaced constantly. So production must be very close to usage. Not to mention that corporations would just LOVE to keep you comming to them with wallets open.

Electic -This is the answer. The oldest production auto tect is the electric car. The materials needed to make em are pluntyfull and easy to get from local/national sources. The technologies are well established. Distribution is as close as your homes plugins. Production is straight forward and varied in there abundance of sources. In cities companies will make and distribute, in the country individuals can make there own. (solar, wind, hydro ect...)
To supply the entire US with electric would take some 10,000 square miles of production area. This is about one quarter of the state of Nevada. It sounds daunting, but it's really not when you consider how many MILLIONS of square miles roof tops cover. Although batteries are not as effecient as they could be, they probably will never be 100%. Even 80% as now is usefull.

Fuel cells -They do not work in cold climates. Almost useless in a third of the US and Europe. Corporations again would love to keep you shelling out cash every week.
