4 trillion pounds.
1 gigawatt-hour is equal to 1,000,000 kilowatt-hours.
Out of our 4,000,000 gigawatt-hours, 50% of it comes from coal; this is 2,000,000 gigawatt-hours.
2,000,000(1,000,000) = 2,000,000,000,000 (2 trillion) kilowatt-hours.
Since each kilowatt-hour is 2 lbs of carbon dioxide, 2 trillion * 2 = 4 trillion lbs of carbon dioxide.
