This is from something called the Energy Policy Institute at the University of Chicago. A few things they have concluded are that particulate air pollution is taking two years off people’s lives on average worldwide, and much more in some developing countries, climate change will impact the economy, U.S. fuel efficiency policy incentivizes the auto industry to make inefficient types of vehicles (although it still takes human beings making cynical, unethical choices to actually do this), nuclear energy could be competitive if a carbon tax were to be introduced, and peak pricing for electricity actually works to reduce and shift demand.
