The city of 60,000 is replacing most of its oil, gas, and electric furnaces for district heat with cogeneration plants, which burn sawdust and timber waste from the surrounding wooded region. Publicly owned cars and buses have switched to burning either biogas made from waste wood and chicken manure, or an 85 percent ethanol blend from Brazil.
Kalmar has become a model for what all of Sweden hopes to achieve.
