How much natural gas is required to generate 1 MWH of

Natural gas has an energy content of 50 MJ/kg. A gas fired power station has an efficiency of about 40 - 50%. Lets say 50%. There are 3600 seconds in an hour so a MWh is 3600 MJ. So the gas required is 3600/(50 * 0.5) = 144 kg Or Natural gas ener
