Coal Power and Global Warming
This is an advert I received from the New Yorker Magazine. Interesting... Sources included for the buffs...
1. Emissions Source: US Energy Information Administration (EIA) 2005.
2. Building Sector Data Source: 2006 Building Energy Databook, EIA.
3. 1 Quad (quadrillion Btu) = approx. 60.4 million metric tons of carbon dioxide (MMT CO2).
4. One medium-sized (500 MW) conventional coal-fired plant emits approx. 3.2 to 4.0 MMT CO2 a year.
5. One billion square feet of existing building area in the US is responsible for approx. 7.68 MMT CO2/yr.
6. Home Depot: Home Depot has funded the planting of 300,000 trees in cities across the US. Each tree will absorb and store approx. one-third of a ton of CO2 over its lifetime.
7. Wal-Mart: Wal-Mart, the largest “private” purchaser of electricity in the world is investing half a billion dollars to reduce the energy consumption and greenhouse gas (GHG) emissions of their existing buildings by 20% over the next 7 years. "As one of the largest companies in the world, with an expanding global presence, environmental problems are our problems," said CEO Lee Scott.
a. Total US building area for all Wal-Mart Supercenters: 437,019,000 square feet (sf).
b. Total US building area for all Wal-Mart stores: 630,494,000 square feet (sf).
8. Every Household:
a. There are 110 million households in the US today.
b. Changing one 60-watt incandescent light bulb to a compact fluorescent saves approx. 156.6 pounds of CO2 each year.
a. The Campus Climate Challenge, a growing student movement in the US, states that global warming “is our problem, and it’s up to us to solve it, starting right here on campus, right now.”
b. Assumption: 3.5 billion sf of existing college campus building in the US.
a. California, which makes up over 10% of the country’s new vehicle market, passed legislation to cut GHG emissions in new cars by 25% and in SUVs by 18%, starting in 2009.
b. A 25% reduction of emissions in cars and 18% in SUV’s sold in California in 2009 is approx. 2.3 MMT CO2.
11. ME, VT, NH, MA, CT, RI, NY, PA, NJ, DL, MD: The Regional Greenhouse Gas Initiative (RGGI) is a ‘cap and trade’ cooperative effort by eleven Northeastern and Mid-Atlantic states to reduce their carbon dioxide emissions to 1990 levels by 2014.
a. Carbon dioxide emissions in 1990 equal 842.04 MMT CO2.
b. Carbon Dioxide emissions in 2003 equal 889.42 MMT CO2.
12. Real GDP (Year 2000 dollars) in 1973 was $4.341 trillion and in 1983, $5.423 trillion. (Source: Economic History Services)
13. Number of vehicles in operation in 1973 was 111.217 million and in 1983, 147.104 million. (Source: US Energy Information Administration)
14. From 1973 to 1983 approx. 19.7 billion square feet (bsf) of residential building and 13.3 bsf of commercial building were built. (Source: US Census, EIA)

16. Total US CO2 emissions in 1973 was 4685 million metric tons (MMT) and in 1983, 4331 MMT. (Source: EIA)
