San Antonio, Texas, is the first city to convert its human waste into renewable energy.  The city’s Dos Rios Water Recycling Facility recycles waste water and waste solids and now it is using the methane gas from the waste solids to produce natural gas.

Technology developed by the Massachusetts-based company Ameresco takes methane gas from solid waste held in big holding tanks and creates clean burning natural gas.  Ameresco is selling the gas on the open market and paying the city a percentage of its profits, estimated at $200,000 to $250,000 annually.

Meanwhile, a suburb of Phoenix, Arizona is considering a proposal to convert dog waste into electricity.
