1) Methane production via biomass digesters... China already has 5 million of them installed. Gas powered electric generators can be easily adapated for methane. The more you (and your animals) poo the brighter your lights. The technology is simple... requires only brick (stone), mortar, pipe, and a big innertube to store the methane (there are other methods for storage too). Methane can be used as is to cook on, keep water hot, or run a light.
2) Biodiesel... Heated soy oil substitutes for diesel and only requires small amounts of the real deal on startup and shutdown. Even the real stuff needed for startup can be substituted with a glycerine-chemically-removed version of soy oil.
Do your google research on biomass and biodiesel! I intend to convert my septic system to a biomass reactor within 2 years and my truck to biodiesel within 3. Goodbye big oil, these are the future's solutions. AND they are decentralized!

So when the top soil has eroded away from planting of soy to supply the increasing demand of biofuels, what will we use to plant the crops we eat? This is the number one problem with all plant derived fuels intended to replace oil. The top soil will erode away, more farm land will be taken away from edible crops and a massive world food shortage may hit.
