I often see people claim that because clean energy sources like solar, wind, or nuclear are manufactured using fossil fuels their emissions are high. But thats absolutely not the case: even accounting for full lifecycle emissions they are vastly better than burning coal or gas:

Electricity generation per person in the United Kingdom has fallen by a third from its early-2000s peak. Globally, electricity generation per person has grown by more than 50% this century. In the United Kingdom, things have moved in the opposite direction.

At least two dozen countries have launched programmes to swap oil and gas for electricity since the Iran war began. I spoke to ABC's PM about why, alongside António Guterres and Fatih Birol. Crises push countries towards energy they can make at home.

Did you know that producing one pound of beef is 25-50x worse for climate change than burning a pound of coal? In fact, it’s one of the most polluting things we can consume. And grass-fed beef is usually *even worse* — thanks to its much higher land use and methane emissions.

This is why cities need trees. Hard surfaces and parked cars can reach extreme temperatures, while shaded grass and tree-covered areas stay dramatically cooler. This is the urban heat island effect in one image: hard surfaces absorb and radiate heat, while vegetation and shade reduce it.

"Heat pumps just shift gas burning to the power station." Wrong. Even if 100% of electricity came from gas, a heat pump at SCOP 3.8 uses 51% less gas than a boiler. At a terrible SCOP 2.5, still 25% less. David MacKay made this point in 2008. The maths hasn't changed.
