Your typical city dweller doesn’t know just how much coal and uranium he burns each year. On Lake Shore Drive in Chicago—where the numbers are fairly representative of urban America as a whole—the answer is (roughly): four tons and a few ounces. In round numbers, tons of coal generate about half of the typical city’s electric power; ounces of uranium, about 17 percent; natural gas and hydro take care of the rest. New York is a bit different: an apartment dweller on the Upper West Side substitutes two tons of oil (or the equivalent in natural gas) for Chicago’s four tons of coal. The oil-tons get burned at plants like the huge oil/gas unit in Astoria, Queens. The uranium ounces get split at Indian Point in Westchester, 35 miles north of the city, as well as at the Ginna, Fitzpatrick, and Nine Mile Point units upstate, and at additional plants in Connecticut, New Jersey, and New Hampshire.
