  Coal Generation - Power Plant Equivalents

In order to replace the current 300 gigawatts of coal capacity the US has today, it would require:

Solar Setups

300 million

It may take more - average daily sunlight by region varies.

Windmills

860,000 large windmills

They would occupy an area the size of Ohio, NJ, PA & MD combined

Nuclear Plants

300 -1,000 megawatt plants

Could take as long as 50 years to build

Combined Cycle Natural Gas Plants

1 thousand

The US would need to increase its annual gas supplies by 70%

  Coal and Electricity Equivalents - 2001

On Average:

  • One ton of coal is the equivalent of approximately 2,000 Kilowatt Hours of Electricity. One thousand KWh's is the equivalent of about half a ton of coal (1,000 lbs.).
  • The average residential electricity customer in the U.S. uses 877 KWh's of electricity per month, or 10,500 KWh's annually. Electricity consumption of 877 KWh's of electricity monthly would require approximately 29 pounds of coal per day, 870 pounds of coal per month or a little more than 5 tons of coal per year.
  • 1,000 KWh's of electricity is the equivalent of 34 days use per household.
  • One million short tons of coal would be enough to provide electricity to more than 190,000 customers annually. One short ton of coal could provide a residential household with electricity for 2 months.

Notes: Assumes 10,119 Btu per KWh at fossil fuel plants, approximate heat content of 20.479 million Btu per short ton of coal, and average monthly U.S. consumption of 877 KWh.
