1000 kilowatt-hours of electricity is equivalent to the average amount of electricity consumed per month by:
• 574 fast-food meals.
• 34 pieces of firewood.
• 28.5 gallons of gasoline.
• 274 pounds of coal.
• 34 therms of natural gas.
• lead-acid battery weighing 61,110 pounds.
1000 kilowatt-hours of electricity is equivalent to the energy stored in each of the following:
1000 kilowatt-hours of electricity production emits the following pollutants:
Pounds Ping pong balls (eq. vol. @STP)
CO2 1,725 14,960,000
SO2 4.12 35,900
NOX 3.48 30,530
And require 422 gallons of cooling water
Note:
Approximate surface area of the earth is 4πr2, or4π(6.378 106 m)2. This comes to ~5.112 1014 m2,and a hemisphere is ~2.556 1014 m2.
Approximate average insolation is 343 W/m2.
So the total power falling on one hemisphere is:
343 W/m2 2.556 1014 m2 = 8.78 1016 W
U.S. energy consumption is ~100 quad/yr, or1.05 1020 J/yr.
World energy consumption is ~4.71 1020 J/yr.
