Sure. Two thoughts 1. It is good to put solutions as close to problems as possible. I personally believe we should be spending billions on climate change, because we will eventually anyway, and we should soften that hit. It's hard to allocate that spending though. If you make that tax functionally dependent on the thing you want to change, then the problem and mitigation are coupled. This is emotionally pleasing, which should not be minimized. 2. My personal belief is that solar panels can be made to work by people who want them to work. I call this a marginal solution. The inverse is that if solar panels are forced to be installed by people who are not motivated to make them work, then they will not work. There are many ways that solar panels may fail to deliver usable energy, from shading to upkeep of inverters and connections to replacing damaged panels; if you don't believe in solar panels, you may not fix these problems.
