I was deeply disappointed by the lack of nature/science/climate/enviro on many major end-of-year book lists—so I decided to make my own!

I agree we should not be burning stuff. But now that coal is gone if you explore annual electricity-related emissions from the UK, the vast majority that is left is from fossil gas, not biomass. 🧪🔌💡☀️💨🔋
Comparison of annual emissions by source for electricity generation in the UK shows that the vast majority of what is left, ~47 Mt CO2e/y, is from fossil gas, not biomass.

Six years of technological progress and deployment have seen key renewable electricity generation costs drop by 45% to 56% while fossil fuels have become slightly more expensive. Source: IRENA 🧪🔌💡☀️💨🔋 #FossilFuelsAreStrandedAssets
Comparison of generation cost plots for 7 types of renewable energy generation from 2017 to 2023. Biomass, Geothermal and Hydro have remained the same or increased in cost slightly. The remaining 4 have dropped in generation cost ($/kWh) as follows: PV (0.1 to 0.044); CSP (0.22 to 0.117); Onshore Wind (0.06 to 0.033); Offshore Wind (0.14 to 0.075).
