SINGAPORE - Heat is often an unwanted byproduct in the process of electricity generation. But scientists here have found a way to turn it into something useful.

Instead of letting the heat escape into the atmosphere, it is now being channelled to power the air-conditioning system in the Agency for Science, Technology and Research's (A*Star) Experimental Power Grid Centre on Jurong Island.

This system, known as the Combined Heat and Power plant, was on Tuesday morning commissioned by the centre, Hitachi and the Building and Construction Authority.

It was jointly developed by A*Star's Experimental Power Grid Centre and Hitachi, and funded by the A*Star-Ministry of National Development Green Building Joint Grant call.
