I think we will need to see a serious upgrade to the grid before some of the change occurs.
Not to mention overcoming the past, when everyone went to electric heat because it was so ''cheap''.
From the more recent changes in windows... seems solar is back on the page. Lots of manufacturers offering some sort of ''Passive'' option.
Not sure how well that will work without thermal mass... but I expect that I should start seeing it in some designs.
