Taking matters into our own hands is a nice thought, but solar+battery are not happening on any meaningful scale. Such installations rely heavily on subsidies and absent far better battery technology than we have, will always depend on the grid. However, the grid can't support more than a small fraction of solar, as California is learning now.
The problem we face is that most "greens" have lost sight of the goal, which should be maximizing reduction of emissions. Instead, they are busy waging a war on nuclear, on behalf of fossil fuel interests. They measure success by "capacity" and renewable installation rate, while ignoring emissions, which are steady or increasing. Prematurely closing nuclear plants in places like Germany and California has essentially wiped away any potential benefit of their renewables, because they are inevitably replaced by fossil fuels. Every time. The only real change is substantially increased retail electricity rates.
The recent lawsuit against zero emission credits in New York is quite telling. ZEC are an attempt to recognize the value of clean energy from nuclear, which is unfairly disadvantaged by generous renewable incentives which exclude nuclear, and temporarily low gas prices thanks to the glut of supply. The ZEC hedges against the inevitable rebound in gas pricing and its volatility, ultimately saving consumers money and ensuring that retail electricity prices will not skyrocket.
This lawsuit demonstrates their real intention. Note that renewable-only incentives have encountered no resistance, because they lock in gas and coal backup indefinitely. With nuclear out of the way it will allow them to make the most of their renewable partnership and drive up fossil energy prices. That would be acceptable if the hybrid fossil/renewable system could economically reduce emissions, but that has yet to happen even once.
