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.

Rooftop solar 'cannibalising' power prices as Australian generators pay to stay online - ABC News (www.abc.net.au)

  • 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

Sure! As far as I know, county and city ordinances permitting, you can be off grid in CA.

However, if you're on grid, and you connect your solar panels to your home electric system, your solar power is now connected to the grid. I don't think you can segregate electricity by source. You could in theory have some of your home powered by your solar and some of your home powered by the grid, separate systems that don't connect, but I think that would be both dangerous and illegal. Maybe you could have an ADU that's totally solar powered while your house is on grid?

And googling today - it's been a while - it looks like CA regulators withdrew their shitty fee schedule and approved a slightly less shitty fee schedule, so good news there ๐Ÿ˜†

There are solar inverters that will just take some load off the grid, but never put power into it for this use case. It's technically connected to the grid but for the grid, there are no downsides or risks.

If the fee also applies to that, it's just straight up stupid.
