One man's garbage is another man's biogas

Awesome article in the New York times regarding how Kristianstad, Sweden has converted their biowaste into biofuel - heating most of the city and providing biogas to all government-operated vehicles. This has pretty much cut out all needs for municipal and utility petroleum-based fuels.

The city of Kristianstad (which was apparently nearly bankrupted during the oil shocks of the 1970s from fuel costs) pay half for energy than they would if they relied on oil, easily get rid of biowaste from their agricultural sector that would have to be disposed of anyways and could intoxicate the water supply if not properly taken care of, employ tons of people, and have as a byproduct, produced technology and expertise within their citizens that could be exported probably for loads of cash.

So, so, fricking smart. Why can't we do this?
