How the electric grid works is important to understand they myriad ways it could fail, including lack of maintenance after deregulation, the essential role of natural gas as the backup since batteries, hydropower, and compressed air storage can’t be scaled up, the difficulties in setting up a smart grid, or a distributed grid and more

Demand reduction of electricity to balance the electric grid

Demand reduction of electricity to balance the electric grid by Alice Friedemann By the time a smart grid is integrated into all the existing computer systems, wasting electricity with each round-trip of information, (rolling) blackouts are likely to be occurring … Continue reading

Not enough wind, solar, geothermal to replace fossil and nuclear power in the 11 western states of the WECC

California, Oregon, Utah, and Washington have already developed most (if not all) of their prime-quality in-state resources. You would think that the more wind and solar power is added over a wide area, the more fossil fuel power plants you … Continue reading
