CA and NV have DECREASED their year-on-year grid electricity demands by growing roof PV more than new grid demands (datacenters, EVs, heat pumps) have increased
CA has the 3rd-most data centers and by far the most EVs
Other states could take a lesson in how to avoid increases in grid demand

Busting another myth. This one on how much mining is needed for fossil fuels versus renewables.
We will need orders of magnitude fewer mines and orders of magnitude less mined material in a clean, renewable energy world.

A transition to 100% Wind-Water-Solar across all energy sectors in the U.S. requires only 35% of the land used for energy by fossil fuels and biofuels today.
It is current energy that is hogging land. Renewables reduce land use.

A bus of Bronx middle schoolers pulled up to the Capitol this morning for a long-planned field trip just a few hours after the government shut down.
All Capitol tours were cancelled as the guides can’t work in shutdown.
So I escorted them in myself and gave them a personal tour. They were great!

Here is how U.S. all-sector end-use power demand & supply would have decreased 1960-2023 if we had gone through the 5 stages of electrification to transition the U.S. to WindWaterSolar.
End result: 56.7% less demand.
