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.

You forgot battery storage (200 usd/kWh) and non-generation use for natgas.

Also, that's a year for the solar panels to get 1.5 TWh but the tanker probably makes that in a month.

Their argument is per unit of cost. But natgas and electricity is not fungible. Even electricity from renewable generation is not fungible with dispatchable generation.

Well the argument was about energy cost. 1.5 TWh is 1.5 TWh, however you choose to spread it out.

You seem to be worrying about power, which is a fair but separate issue to be concerned about.

The latter will still benefit from cutting down use a lot.

[–] eleitl@lemmy.zip 2 points 1 week ago

Sure, the less methane burned in peaker plants and AI DC gas turbines, the better.

It's important for full conversion of the grid, but for just cost of energy, it isn't needed. While 100% of the generated energy is used during the day there's nothing left to store. I think a lot of places are still in this situation. But yeah, the more solar you build the more important that cost becomes.
