Google Architecture 2030 and Better Buildings Initiative, these plans have all kinds of incentives that are NOT from government, the best one is to give preferred interest rates based on how green you build. Edward Mazria is the man behind this, he wrote the best book I have found on the topic of passive solar design and construction. My retirement home has a lot of glass on the south side, the sunlight comes in and warms a lot of tile and granite in the kitchen/dining area. I like to stand in the window on a sunny winter day and feel the warmth while I watch my working neighbors shovel snow.
There was a time that air pollution was due mostly to tailpipe emission, but congress mandated cleaner engines and the auto industry stepped up and in less than a decade we had the computer controlled fuel injected engines that now are putting out more power/torque and better fuel efficiency, and of course, a mere fraction of the air pollution. One thing, tho, that should be an embarrassment to the auto makers, is that MOST of the initial fuel efficiency gains were gained by OLD TECH, the overdrive transmission.
Now, thanks to most of our electricity coming from coal, it is our buildings that are the biggest source of air pollution.
I am in favor of more nukes. If I was in better health, I could get a nice high paying job as a contractor during construction phase, as an Instrument Tech and Metrology Tech. But the Parkinson's has vetoed that. If you saw my unedited typing, you would know what I mean.
