How much carbon dioxide is produced per kilowatthour when generating electricity with fossil fuels?
You can calculate the amount of carbon dioxide (CO2) produced per kilowatthour (kWh) for specific fuels and specific types of generators by multiplying the CO2 emissions factor for the fuel (in pounds of CO2 per million Btu) by the heat rate of a generator (in Btu per kWh generated), and dividing the result by 1,000,000.
Below are the number of pounds of CO2 produced by a steam-electric generator for different fuels using the above formula and the average heat rates for steam-electric generators in 2012 for calculating the amount of CO2 produced per kWh:
|Fuel||Lbs of CO2 per Million Btu||Heat Rate (Btu per kWh)||Lbs CO2 per kWh|
|Distillate Oil (No. 2)||161.386||10,416||1.68|
|Residual Oil (No. 6)||173.906||10,416||1.81|
