>Don't you want people to use energy sources that are better for our entire world, even if it costs you like $10 more in taxes per year?

If everyone gets the benefit it's either A) exactly the same cost but with additional government program or B) some form of wealth distribution and not necessarily in a direction you favor

Also large solar installations are significantly more cost efficient.

Mind you I am IN FAVOR of subsidized residential solar, but let's not pretend government money is free.
