Would having a variety of fuels for diffrent parts of society be a first step in our current oil crisis?

Let me first say i havent done much research in my propositiions, so if there is a reason why this would not work let me know!

But i was just thinking if this would be a good idea, for in the u.s. to first stop all import of forign oil and switch to reserves we own. and then use the reserved oil for commercial viechles and power production only, and develop a hemp fuel that we would use in all private viechles and energy production. this would help develpo jobs in the hemp fuel production and leave us from being hostage to other countries supply regulations and issues and wars and stuff like that. in the meen time rapidly develpot alterative energys to run what the oil is running to get us off oil for good. eh?

Electric requires heavy batteries that are environmentally unfriendly, and hydrogen for fuel cells is dangerous and expensive. So my guess is that oil will become reserved for mobile applications (cars, trucks, ships, etc.) because it has the right properties, ever more plentiful natural gas will be used for stationary applications (electricity generation, home heating, factories, etc.), and fringe energy sources -- wind, solar, tidal, geothermal, etc -- will be used for point-of-use and small scale applications (home solar panels, community wind farms, and the like). This will be driven not by regulation but by market forces; as oil becomes harder to extract, its price will rise so it will be used only where it makes sense. As long as fracking becomes environmentally acceptable, the United States has over 100 years of available natural gas, and that is just from known reserves, so there is lots of time to refine alternative energy sources. Gas is easily transported through pipelines, so it makes sense to develop the infrastructure necessary for its more widespread use in static applications. But any time you try to use agricultural products for fuel, you screw up food production, either by diverting a food (corn, say) to fuel use (ethanol), or by, as Jonathan says, using land that could better be used for food growing.

Also, if you grow hemp and use petrochemicals, then that still requires a lot of oil. Also, it seems that the valuable parts of hemp are sold for food, where the farmers get a much better price. I got some of this info from http://biodieselmagazine.com/articles/1434/hemp-biodiesel-when-the-smoke-clears/ and from http://www.guardian.co.uk/environment/blog/2008/jan/28/whyishempoffthebiofuelme.
