At this current crazy moment, most of the “Western” world (Europe, the U.S., Canada, Australia) is hell bent on achieving a “net zero” energy system.
As I understand this concept, it means that, within two or three decades, all electricity production will be converted from the current mostly-fossil-fuel generation mix to almost entirely wind, solar and storage. On top of that, all or nearly all energy consumption that is not currently electricity (e.g., transportation, industry, heat, agriculture) must be converted to electricity, so that the energy for these things can also be supplied solely by the wind, sun, and batteries.
Since electricity is currently only about a quarter of final energy consumption, that means that we are soon to have an all-electric energy generation and consumption system producing around four times the output of our current electricity system, all from wind and solar, backed up as necessary only by batteries or other storage.
A reasonable question is, has anybody thought to construct a small-to-moderate scale pilot project to demonstrate that this is feasible?
