Whenever I give our presentation on CES and on the clean energy plan, I always try to say that all forms of energy generation are problematic. While there is a ton that we can fairly easily do to reduce carbon emissions, we are still a ways away from having the kind of sustainable energy system that produces no burdens.
Last week, the New York Times offered two reminders. First, a recent study finds (unsurprisingly) that wind farms don't offset local air pollution (like smog and acid rain). This is where the engineered and accounting modes that dominate climate policies right now run into local realities.
Second, buses, particularly school buses, continue to spew pollution, despite the availability of retrofit technology. Of course, the problem is money.
