So AI companies’ product, that they charge us for, also has a measurable impact on the electricity prices we, and presumably, all industries pay?

All programs, tariffs and subsidies are ultimately paid for by Joe consumer, who has an increasing percentage of the load, and absolutely nobody to pass the it along to.

The AI hype is probably collapsing soon. But that won't solve the issue. It's basically the only thing that drives the ponzi scheme, sorry, the "stock market growth". It'll end in tears for working people again.

Are there any utilities that have progressive rates electricity rates? Where the first X kWh are $0.12/kWh, the next Y kWh are $0.15/kWh, and then anything over Z kWh are $0.18/kWh, etc?

Though it seems that nowadays, much of that cost goes to taxes and fees, rather than electricity rate itself.
