My latest at IER. An excerpt:
Again I point to the tightrope Krugman is walking here: He wants his readers to get on board, cheerleading these “green” power sources because they keep getting so efficient.

If they’re really like information technology, it doesn’t take government favors to lift off. Nobody ever said we needed a “calculator tax” to get people to start using computers.
