So, does "human imagination" to find new sources of energy apply only to fossil fuels? Doesn't it also extend to the ingenuity needed to develop clean, sustainable energy from the sun and other alternative sources?
Maybe before Jonah Goldberg promotes fracking and asteroid mining (did I read that correctly?), he might first consider supporting solar energy. That's not pessimism because we think we are depleting our source of energy (fossil fuels); it's choosing a better source.
As Thomas Friedman stated in his book, "Hot, Flat, and Crowded," the Stone Age didn't end because we ran out of stones; we invented our way out. I hope we can do the same again, moving from a dirty-energy economy to a clean-energy economy.
