I keep reading how big batteries are all it takes to make wind and solar reliable as the sole grid electricity source. The reality is that making wind and solar work at all requires a fantastic amount of battery backup, far more than is possible.

Below is an example using the PJM grid. PJM is America’s biggest grid operator, with a territory covering the Mid-Atlantic and points west. Their territory includes the Washington, DC metro area, where all the federal bigwigs live, making it a good place to start. I also live there.

We are quantifying a fantasy, so let’s keep it very simple. In fact, the basic question is why hasn’t PJM done this simple analysis? They do a lot of sophisticated grid modeling. Or maybe they have done this crucial assessment, but it is a secret, which is even worse.

The unity of government which constitutes you one people is also now dear to you. It is justly so, for it is a main pillar in the edifice of your real independence, the support of your tranquility at home, your peace abroad; of your safety; of your prosperity; of that very liberty which you so highly prize. But as it is easy to foresee that, from different causes and from different quarters, much pains will be taken, many artifices employed to weaken in your minds the conviction of this truth.  George Washington - Farewell Address

Democrats, and Greta Thunberg, would tell you no price is too much to save the planet!  By the way, did she give up her climate gig for a Hamas defending career? :whistle:
