On average, which is most efficient in coverting heat into electic power?
- Coal boiler power plant
- Natural gas-fired turbine power plant
- Natural gas combined-cycle power plant
-
Sorry, that’s incorrect.
On average, a typical coal-burning power plant in 2013 was about 33% efficient in converting heat energy into electrical power. A gas-fired plant was about 42% efficient. And in natural gas combined-cycle power plants—in which waste heat from a natural gas turbine is used to power a steam turbine—generation may be as much as 60% efficient.
