Since John McCain picked a certain person who will not be named as his running mate, I’ve seen a number of politicians (including the unnamed running mate) state that Alaska produces twenty percent of America’s energy. That sounded a bit off to me, but of course I didn’t follow up. Matthew Yglesias did, though, and reports that Alaska produces 3.5% of America’s energy (and 14% of America’s oil). has more on this topic.
