Adding $30k to your mortgage would cost like $150 a month extra or so.
So instead of having ~$1800/yr going to your energy company's coffers, where they might use it to innovate and actually one day make clean energy cost effective, it should go straight to your bank's bottom line in the form of interest. While it may cost consumers the same amount, that sounds like a net negative to me.
So... You think we should forego installing a clean energy source that is available today and instead give that money to a company that does not provide clean energy in the hope that maybe they will provide the clean energy that we could have had today at some point in the future.
If you one day want financially viable clean energy, there are certainly better places for that money to go than into your bank's pocket - such as to energy providers, who could then use that money for R&D.
Tell me how many banks are spending their profits doing clean energy research.
