Great work here from @carbonbrief.org , debunking common myths about solar power.
The reason that solar power makes so much sense is fundamental physics - it takes energy in its most useful form, as soon as it arrives on Earth, before it's "taxed" in entropy. Making use of it is a slam-dunk win.

Atmospheric CO2 has passed 430 parts per million.
The last time atmospheric CO2 was at 430 ppm was during the ancient Pliocene Era, three to five million years ago, and humans didn’t exist.

It's a myth that "hydrogen combustion produces only water vapour".
Burning hydrogen results in harmful NOx emissions. In urban areas this becomes the dominant source of NOx pollution if we switched to hydrogen for heating.
Shocking to see H2Heat project financed by the EU peddling such untruths 👇

Does it make sense to rip out a new gas boiler and replace it with a heat pump? From carbon perspective yes: Replacing a new gas boiler with a heat pump in the UK cuts emissions by 77-86%.
This includes embodied emissions from manufacturing.
A heat pump offset its embodied carbon after 13 months.

We can’t decarbonize energy by focusing on supply alone—we must tackle demand too.
🔹 Efficiency has cut more emissions than renewables
🔹 Smarter demand = less fossil fuel reliance
🔹 Cleanest energy is energy we don’t use
