  • Wholesale power prices are increasingly turning negative at times of high solar output
  • Observers say rooftop solar is "cannibalising" electricity prices and hitting large-scale solar hard
  • There are calls for storage and greater daytime demand to help soak up solar production

I'm sure this has been discussed, but storing your solar energy as potential energy could avoid paying connection fees. Pump some ground water into a raised tank - or hoist heavy objects (large logs)?

Now that I type it out, it seems either dangerous or inefficient or not cost effective. Or all of the above.

Fun to think about, though

There was a company that stacked concrete bricks to store electricity, with the point being that on demand the crane could pick up bricks and gain the energy from dropping them down. Hit all sorts of news sites, never heard of it reaching practical use.

EDIT as noted by another commentor, apparently it did.

Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world. About 1C of total warming. Second chart: about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability. Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases. About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
