Any real point to erroneous numbers?

The April 1 article about the impact of Earth Hour was most interesting. However, in the writer's desire to be a "greenie," the math was hard to understand.

He said the 7 percent drop in power usage during Earth Hour, as reported by ComEd, was the equivalent of removing a million cars off the road for an hour or 72,000 gallons of consumed gas.

Now let's be realistic. If there were a million cars on the road for an hour they would drive at 50 miles an hour, going 50 million miles. Extending this further, if each car got 20 miles to the gallon, that would be 2.5 million gallons.

Now to the most pertinent point -- the utilities don't use gasoline to generate power. So what was the point in providing us all those incorrect figures?
