Clean Energy Investment Now Over Twice Fossil Fuel Spending

NEW @IEA data: clean energy investment is now more than double fossil fuels. $2,155bn vs $1,008bn in 2025. The crossover happened around 2016. Since then the gap has only widened. What was a narrow lead a decade ago is now a >2-to-1...

Europe’s Gas Supply Safe; Worst‑case LNG Spikes to $54.9

NEW RESEARCH: We modelled three Hormuz closure scenarios. Europe never physically runs out of gas in any of them. But under the worst shock, LNG hits $54.9/MMBtu, above the 2022 peak. Full paper here https://t.co/6fJzMRx2i3 https://t.co/wqPJbHbJua

Wholesale Electricity Prices Follow Gas, Not Renewables.

Wholesale Electricity Prices Follow Gas, Not Renewables.

NEW ANALYSIS: Do renewables make electricity cheaper or more expensive? I pulled together wholesale and retail data across Europe and the US. Wholesale prices track gas exposure, not renewables share. Retail prices barely track either. Full piece👇 https://t.co/kl1w1qFwJR https://t.co/B3qPwnRf1h

Renewable Share Shows Little Impact on Prices

Do US states with more renewables pay more for electricity? No. Do they pay less? Not necessarily. Across all 50 states in 2024, the correlation between renewables share & residential retail price is very weak in either direction. More next newsletter https://t.co/In5lBaF2ox...

Electricity‑gas Price Gap Blocks Europe’s Home Electrification

Electricity‑gas Price Gap Blocks Europe’s Home Electrification

Electricity-to-gas price ratio: biggest barrier to electrifying European homes. Heat pumps deliver ~3 units of heat per unit of electricity. The maths works in Sweden but not everywhere. Much of gap is policy. More analysis in my forthcoming newsletter https://t.co/In5lBaF2ox https://t.co/lvOin2nN2m

Hydro, Not Wind‑Solar, Drives Low‑Cost Power

"Renewables make electricity expensive" line doesn't survive contact with data. But neither does claim that wind+solar automatically deliver cheap power. Europe: renewables r = -0.51, wind+solar only r = -0.14. Hydro does heavy lifting. Full analysis soon https://t.co/In5lBaF2ox https://t.co/WFQmPbIjqk
