A natural gas power plant is 60% efficient. If one cubic meter of natural gas provides 1000 BTU's of electricity, how many BTU's of waste heat were produced? Thank you!

Efficiency = Output / Input = 60% = 0.6
Energy Output = 1000 BTU of electricity
So energy Input = 1000 BTU / 0.6 = 1667 BTU
Waste heat produced = Energy Input - Energy Output = 1667 - 1000 BTU = 667 BTU
Energy Output = 1000 BTU of electricity
So energy Input = 1000 BTU / 0.6 = 1667 BTU
Waste heat produced = Energy Input - Energy Output = 1667 - 1000 BTU = 667 BTU
