Various solutions for (incentivizing) energy efficiency:

- "First open-source global energy system model" https://news.ycombinator.com/item?id=39333285

- There aren't intraday electricity prices in most markets in the United States. (You must have intraday electricity prices to be an EU Member State, by comparison.). Wouldn't intraday prices incentivize energy storage solutions and energy efficiency?

Thanks, Yes I'm a long time electricity maps customer. I also agree that the EU markets data transparency is further along in helping incentivize opportunities here.

Also thanks for the other links!

It looks like they have data for the United States now.

We have public utilities that must raise bonds to grow to scale with demand, and some competitive electrical energy markets with competitive margin and efficiency incentives in the US.

FWIU, datacenters are unable to sell their waste heat, boiled sterilized steam and water, unused diesel, and potentially excess energy storage.

To sell energy back to the grid to help solve the Duck curve and Alligator curve problems requires a smart grid 2.0 or a green field without much existing infrastructure to cross over or under.

To sell datacenter waste heat through a pipe under the street to the building next door, you must add some heat.

"Solar thermal trapping at 1,000°C and above" (2024) should be enough added heat to move waste datacenter heat to a compatible adjacent facility.

Sand batteries hold more heat than water, in certain thermal conditions.

Algae farms can eat CO2 and Heat, for example.

Cooling towers waste heat and water as steam.

The Landauer limit is presumed to be a real limit to electronic computation: changing a 1 to a 0 releases energy that can't be sent out on the negative so it's wasted as thermal energy.

Photonic computing, graphene computing, counterfactual computing, superconductors, and probably edge chiral currents do or will eventually do more computation per unit of energy.

Ops per wHr metrics quantify the difference.
