From a carbon perspective, net metering was basically paying homeowners to provide useless power to the grid (at the bottom of the duck curve) but be able to cash it in when they actually needed it around 7 pm. This meant generating useless solar power and in exchange for letting burning a ton of natural gas when you actually needed the power.
The next step is pairing solar with residential and grid scale storage. Personally, with how intermittent production can be now, the grid should be more like AWS. Allow for per minute billing and rates that fluctuate for some customers. If you can pair storage with solar (or even just storage if you could buy low sell high off the grid), that would be the next big step in the renewable revolution.
Net metering always had to die for the next step (storage) to happen. With the electric car mandate coming into 2035 so that millions of homes will own a giant battery this will eventually be even more important.
