The Electric Grid Explained In 10 Charts

The late German philosopher Martin Heidegger was keen on the “thingness of things.” While researching Heidegger, I stumbled upon an essay by Bill Brown, who studies “thing theory.” In that 2016 essay, Brown writes, “Heidegger concentrates on an object that discloses the thingness of things in its unconditioned autonomy: standing alone and standing forth, the thing things.”

The thingness of things is an apt way to discuss the electric grid because most people have no idea what the damn thing is. That ignorance makes the electric grid an almost perfect subject for hyperbole and big promises.

Last February, the Department of Energy published a report — the “National Transmission Needs Study” — which claimed the U.S. needs to build 47,300 gigawatt-miles of new power lines by 2035. It did not bother to explain what a gigawatt-mile is, nor did it say how many miles of transmission are being built annually. (As I explained last May in “47,300 Gigawatt-Miles From Nowhere,” the answer is very few.)  

Last May, the New York Times published an editorial titled “We Desperately Need a New Power Grid. Here’s How to Make It Happen.” It said “To tap the potential of renewable energy, the United States needs to dramatically expand the electric grid between places with abundant wind and sunshine and places where people live and work. And it needs to happen fast.” The Times continued, saying the U.S. needs “a plan to build a new electric grid.”

Last November, Energy Secretary Jennifer Granholm tweeted, “With @POTUS investing in America agenda, we’re giving our electric grid some much-needed TLC.” Granholm was touting the administration’s “largest ever investment in America’s electric grid,” a move that she claimed would result in more “clean energy,” lower costs, and (of course) “union jobs.”

So, what is the electric grid? I like to think of it as the Mother Network. It’s the energy system that fuels our society’s most-critical networks, from hospitals and traffic lights to water systems and the Internet. Meredith Angwin, the author of the landmark 2020 book Shorting the Grid: The Hidden Fragility of Our Electric Grid, has a good definition. She recently told me the grid is “everything that connects us to electricity.” In these charts, I ignore what Angwin calls the “policy grid” and focus mainly on the physical grid — the sprawling network that allows electricity worth  $500 billion per year to be generated and delivered to customers from Maine to Hawaii and from Florida to Alaska.

I can't help but notice that they keep forgetting a key element for any "solar/wind" dependent grid . . . storage. 

You can produce all the power you want when the sun is out and the wind is blowing, but it's pretty useless on a becalmed night unless you have enough batteries.

Global energy storage markets will grow 13-fold from 2018 to 2024 to reach 158 gigawatt-hours and $71 billion in investment, Wood Mackenzie Power & Renewables reports | Greentech Media

If I'm doing my math right (BIG assumption!)  the US wind/solar generating capacity is about 220 gigawatts.  From the link above, we'd fill the global battery in about 30 min.  Then what?
