class=”textlink”>Glenn points out a fellow who notes the potential of solar energy:
“If 2 percent of the continental United States were covered with photovoltaic systems with a net efficiency of 10 percent, we would be able to supply all the U.S. energy needs,” said Bulovic, the KDD Associate Professor of Communications and Technology in MIT’s Department of Electrical Engineering and Computer Science.
Um, ok. Glenn notes “Two percent is a LOT of land”, but that’s understating the case a bit I think.
Let’s do some math! (I was told there would be no math. Shhh!)
According to this page, the total land area of the U.S. is 3,537,379 square miles. Take away Alaska and Hawaii to get the continental U.S., and you are left with 2,959,005 square miles. Two percent of that is…
Fifty-nine thousand, one hundred and eighty square miles. That’s 59,180.
For perspective: Over half of the fifty states are smaller in area than 59,180 square miles. The closest in size to that number are Iowa (55,869), Michigan (56,804), and Georgia (57,906).
So: who’s for paving over Georgia?
Because unless I’m missing something, that is what we’re talking about: literally paving over that much area, and I have to assume utterly destroying any flora, fauna, or other living things that are unlucky enough to have been previously occupying it. Unless they happen to, you know, not require sunlight.
Now that would be one hell of an Environmental Impact Study.
Professor Bulovic seems to have thrown out this statistic as a positive for solar energy, but he’s obviously never negotiated with a local zoning board. If that’s the best future we can hope for with solar as our primary energy source, I suspect even the most strident environmentalists will cry out, “Bring on the coal!”
