We heat on winter nights, air condition on summer days

Central Valley groups oppose elimination of natural gas in California homes and businesses

In the margin are energy storage costs, then we have the alternative that natural gas is often burned in excess. Close the boundaries, and get the quantum solution. My thinking is just get solar into the grid in summer, now. The greatest payoff, and forget, for the moment, the alternative for winter heating.

If we had better bio energy conversion, we can sequester that natural gas, for a while, in biofuel. So we have these two unknowns, biofuel and energy storage. This is like the analytic extension of a rational outcome to imaginary axis, we have this long term, incomplete sequence. But we cannot ignore the long term, crawl back is hugely expensive.  

So the analytic extension becomes pilot programs that define better vectors off to the long term. Better to subsidize industrial research in small quantities now, get better definitions of the future.
