The Economist – well-known for its fine graphs – published another last week. This was about how electricity demand in California varies across a sunny day (most days that is), and how an increase in solar power availability (most of which is local to demand) is causing problems for the grid. This will also happen here, but not to the same extent, and only on very sunny days.
It's one of several (obviously solvable) problems I've come across with how the welcome advent of renewable-sourced power is causing headaches for an antiquated supply grid. It's a problem that Semington A contributes to in a very modest way. I wonder if any of this gets taught about in the rush to be ultra-positive about renewable power.
