If you have enough time and space and animals you could be generating your own electric or heat from "digesting" (ie enclosed composting) of your animal manure. You can use ANY combination of manure from Horse, cow, goat, Sheep, Dog, Pig etc PLUS certain parts of your Garbage (Ie left over foods) and a few other items. Anyway, using certain techniques you can produce methane gas that you can use in a variety of ways.
Methane gas can be used like propane for heat, hot water and cooking, Or it can also be used as a fuel in an engine to power an electric generator.
The sludge (ie leftovers) can be used as fertilizer for your pastures, crops or gardens.
Small time digestors that produce smaller amounts of methane are quite inexpensive to build and help to get you started in the "learning" process on all the " how to's" needed to work your way up to large scale digestors.

This "calculator" gives you an Idea of what size digestor you would would need to build in order to use your manure and also gives you the anticipated out put amounts of methane. If you look thorough the rest of the website there is more good info.

Methane Gas is the NUMBER ONE greenhouse gas being produced around the world only it's being released free willie style instead of being harnessed and used to creat heat or electric.

It takes 2.4 kilowatt-hours (kwh) of electricity to burn a 100-watt lightbulb for a day. The electrical energy available in one cow's daily poop: 3.0 kwh.
And for the record, MANY farmers in third world countries are using methane on a daily basis.
India for example has beeind going Methane gas research and production since the 1930's
quote:
The Gobar Gas Research Station (Gobar is Hindi for cow dung) was founded in 1960 as the newest of a long series of Indian research efforts started some time in the 1930s. As one might guess from the name, the Gobar Gas Research Station has concentrated on studying the production of biogas from cow manure. Ram Bux Singh and his colleagues have biogas plants in operation ranging in size from about 8 cubic metres per day to 500 cubic metres per day. They have plants using heating coils, filters and mechanical agitators to test the change in efficiency, and have also tried various mixes of manure and vegetable waste. There is an immense amount of documentation of all their projects since every detail has been recorded for analysis and future reference.

And even here in the USA there are Daries in Michigan, California and Washington that are producting methane on a large scale and even selling part of their electric BACK to the local companies.
