A lot of these [expensive] incentives are already being wound down, and the ones under control of utilities (e.g. net metering) can radically impact the ROI of things like solar installations. It'll be interesting to see how things stabilize in California over the next few years now that new residential solar doesn't make sense for almost anyone [unless they also have batteries and drive EVs, since electricity is now more expensive than running most gas-powered cars]. Additionally, why would most homeowners spend this kind of money when the vast majority of people only stay in a give house for ~7 years total? The incentives are great, but I don't see substantial changes happening unless it becomes a true no-brainer to replace fossil fuel systems and inefficient infrastructure (windows, roofs, insulation) with updated materiel. Blowing in more insulation is cheap and easy, but most Americans don't have a rainy day fund that would make replacing a furnace with heat pumps something they casually decide makes sense... or gas appliances with electric, or a new roof, etc.
