Until renewables are fully built out, storage is useless. So we burn natural gas at night for a while. When there is enough generating capacity to supply demand and charge storage at the same time, then we install the storage and charge it. Storage will be radically cheaper at that time than now. In the meantime, every spare dollar should go to building out renewables. At some point spending on mined gas declines naturally because it is the most expensive energy.
