It has been a year since we checked in on the usage of the eight EV charging spaces in Lot Y south of Broadway on Chula Vista. I use Lot Y often and have noticed some uptick in usage which has been extremely low in the past as noted here. Last October/November 2020 usage was running a half of a charge per day, per space during Covid limitations. Things have opened up a lot since then–just look at the traffic in town these days. So one would expect some uptick in EV charging as well. Here's the numbers from the city:
2020 minutes 2020 sessions 2021 minutes 2021 sessions
October 2650 121 12,287 366
November 3571 137 13,386 360
So the spaces are being used 2.8 times as frequently and providing 4.1 times as many minutes of juice. That tallies to one and a half charging sessions per space per day. That is still very light usage although I once saw four EVs charging at the same time. I was at the lot on Wednesday afternoon when the regular spaces were very close to full and the eight EV spaces were empty. 
There has been plenty written about the increasing load on the California grid from EVs, but not as much about the environmental effects of all the new batteries for EVs. NBC News jumped on that last week
A nickel mine stretching nearly 4 square miles scars the forest above farmland (in the Philippines). The mine, Rio Tuba, plays a vital role in satisfying the global demand for a mineral more coveted than ever due in part to the explosion of the electric car industry. The raw nickel dug out of the ground here ends up in the lithium batteries of plug-in vehicles manufactured by Tesla, Toyota and other automakers, according to an NBC News review of company filings and shipping records.
With the demand for nickel skyrocketing, the Rio Tuba mine is now on the brink of expanding deeper into the rainforest, adding almost 10 square miles to its current footprint. Local environmentalists fear that it will wipe out the forest’s fragile ecosystem and increase toxic runoff into the rivers that flow past the farmland down below, jeopardizing the crops.
I'm sure there are other mining areas seeing the same growth. There's no free lunch, somewhere, somehow someone pays.
