A decade ago, Kristianstad, Sweden vowed to end fossil fuel use. Very close to their ultimate goal, the city of 80,000 now uses essentially no oil, natural gas or coal to heat homes and businesses. The replacement energy source comes from byproducts from the city’s farming and food processing industries.

The fuel can be burned to generate electricity or refined for car fuel.
