Undistorted prices works fine when you are dealing with and an industry that does not have external social costs. Unfortunately, the private costs associated with energy generation typically do account for all the negative external costs such as health care, climate change and pollution cleanup. Taxes (or tax credits) can add the social costs back in so producers and consumers can make proper market decisions based on the real costs. I love to play the libertarian but Keynesian economics make more sense when market failure has such drastic effects such as climate change and pollution. IMO.
