With increasing demand for cost-efficient and environment-friendly energy, a growing number of hotels, hospitals and major industrial facilities are adopting cogeneration -- a system that makes more efficient use of heat and electricity generated from the same source.

Facilities equipped with cogeneration systems produce their own electricity and use the heat made in the process to warm water and floors or fill other thermal needs on the spot, drastically reducing energy costs.

With interest in the environment rising, power utilities and related industries now hope to bring the benefits of cogeneration to ordinary households.
