"Energy contained in coal" doesn’t make any sense. Is it "energy we could get from burning coal if it was 100% efficient"? "Energy we could get from coal if we could use it in a nuclear reaction"?

Coal (anything) doesn’t "contain" energy. We can transform some things, and some transformations produce energy in some form or another.

The upper line of this graph should be labeled "total energy liberated by burning coal" and the lower one "useful energy liberated by burning coal".

Akstchually energy is a property of matter, or matter is a property of energy, whatever 🤓 but your point still stands

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.
