With limitations on water availability and the importance of water quality, closed-loop, evaporative cooling systems can be a cost-effective technology for both heat transfer and water conservation.

Researchers have used computer models of closed-loop geothermal systems to determine if they would be economically viable sources of renewable energy. They found that the cost of drilling would ...
