Replace Net Metering With Batteries

We should end net metering, including for existing solar installations, and compensate people with a one-time subsidy for battery purchase. I'm going to give an argument from grid efficiency, which I expect to be the main consideration for most people, though the benefit that makes me enthusiastic about this change is actually increasing societal resilience. Net metering is a common form of solar subsidy where you only pay for your "net" usage: the difference between how much you consume and how much you produce.

Say I started a solar farm, putting out a lot of panels somewhere out in the less populated part of the state (MA), and sold the power to the grid.
