I am not set up for it, but if I were getting into long-term fuel shortage, I'd look at running a generator on wood gas. Lots of literature on it - some printed by the government during WW2 - and relatively easy to build. A generator like that and an electric vehicle for commuting would pretty much satisfy my requirements.
Alternatively, using either veg oil or biodiesel in a diesel engine and generator would make a lot of sense. Lot of web sites and info on home-brew biodiesel - if you have a supply of waste veg oil.
If I were in charge of energy policy, I'd make a serious effort to spin up biodiesel. Also, I'd get a serious look at the 'waste organic matter into oil' cooking technology that's supposed to be so great. Either it's great and should be spun up to get oil, or it should be exposed as a fraud. If it's real, then look at the way the government 'requisitioned' all patents during WW2 and get talking to the company on this one.
