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.

Part is regulations. Utah, of all places, recently passed legislation that requires utilities to allow small solar systems to plug into home systems without an application or fee from the utility.

up to 1200kWac

Where I live, you can buy solar, but the energy isn't yours. You can't install a battery and the energy generated only gets you a discount, but never gets you below zero. Essentially you're buying the energy company some equipment for a discount on your bill.

The other part is lack of tenant rights. Which Utah will not be a leader on anytime soon. Our leases have half page long restrictions on what can and can't be on your balcony and the legislature isn't about to back up renters.

It took me a while to reply to this. I thought it was a really good comment though.

I didn’t think about landlords doing their usual douchey thing. But of course this is going to happen because anything that disturbs some apartment owners arbitrary aesthetic vision is going to be banned easily.

I read the legislation. it’s only five pages. It is really biased for single home owners without being explicit about that.

The actual law

I think I did the estimate correctly, under typical sunny Utah conditions you would only make about a dollar worth of electricity a day at current rates with the maximum allowed system.

Up to 1.2kW hopefully.

Yes, 1.2kWac. Did I do the estimate correctly? My quick estimate of the power yield under Utah conditions is anywhere between a dollar and $1.50 a day? Does that seem to be in the ballpark?
