A side note as far as my city's move toward conservation, etc., is that we have created a thriving collection of expanding solar equipment providers. Local companies have gone from a dozens jobs in the industry eight years ago to over two hundred at year's end with no end in sight.
Another local company recently converted all their heating to solar and redesigned their build to use passive solar for much of their daytime lighting. As soon as they completed their conversion they got the contract to build tents for the Army. As it turns out, the only way they could have provided the ongoing low bid was their conversion to solar. The Army uses LOTS of tents.
