There is about 2,860 TWh/y of waste heat accessible in Europe, much of which could be reused.

That’s almost Europe's total energy demand for heat in residential and service sector buildings.

In the US, the share of total income going to the richest individuals is now higher than it was at its previous peak, in 1928.

A recipe for violent social unrest, if you ask me. Rich folks in the US (and elsewhere) should _actively_ work to close that gap at this point. Like, I'm sure it's nice to have lots of money but it's probably not that relevant when your house gets later stormed by the proletariat or whatever?

Please raise a toast 🍻 to J.B.S. Haldane, who in February 1923 presented a vision of England powered by wind turbines backed up by long-duration hydrogen storage.

That vision is now officially 💯 years old.

Poland generated 4.8% of its electricity from PV Jan-Nov 2022.

I say this a lot, but 15 years ago I wouldn't have believed anywhere would ever get that high, never mind northerly and coal-dominated Poland. It really feels like the end of the beginning.

New Fraunhofer ISI study models potential future #hydrogen demand for Germany at different hydrogen prices.

Even at hydrogen prices of €1.65/kg the study foresees almost no hydrogen demand for heating buildings and only small demand for road transport.

Note: This study was not funded by industry but a public research grant instead.
