NEW | UK wind generation reached a new record in Jan 2026, producing 10.6 TWh 🇬🇧🍃
Prev. record of 10.4 TWh was set in December of 2023.
Higher wind meant gas generation in Jan-26 dropped 17% compared to Jan-25, despite higher electricity demand. This saved an estimated £164 million in January.

India's electrification shortcut! ⚡️🇮🇳
Solar, wind, batteries, electric vehicles...India's economy has different tools available than the US and China did at the same stage in their economic development.
The result? An early turn away from fossil molecules towards electrons.

Solar is now larger than gas power in Germany ☀️🇩🇪
Solar doubled from 9% of the mix in 2019 to 18% in 2025.
Next year it could already surpass coal.
The writing is on the wall for fossil fuels ❌

Until 2006, all of South Australia's 🇦🇺 electricity⚡️ came from coal and gas.
Things have changed dramatically since then. Today, more than two-thirds come from solar and wind ☀️
Coal is already gone. A sign of things to come for other power sectors.

NEW DATA
Amid frequent renewables bashing in the US 🇺🇸, it was solar that met the majority of electricity demand growth in 2025 ☀️
Solar grew by a record 83 TWh and met 61% of fast-rising US demand.
Without solar power, US electricity price worries would be much bigger.

UK AR7 auction results are out today 🍃⚡
Excellent results with over 8 GW of capacity!
The strike price of £91/MWh for England/Wales fixed projects was significantly below the administrative strike price of £113/MWh that so many reported on last year, but was always the upper limit.

Solar is and will be the main story in the energy sector for years to come ☀️
It is the dominant driver of change in global electricity generation ⚡️
Growth in Q1-Q3 2025 was much larger than from any other source. Wind was the only other source with a significant increase.

The EV transition in action 🚗🔋
In 2019, only a handful of countries had more than 10% EV sales share
Fast forward to 2025 and the landscape has changed dramatically.
China, the world's largest car market, crossed over 50% this year with many other markets growing rapidly.

Affordable all day solar is here.
Solar already produces affordable power during the day.
Rapid battery cost declines now mean that a solar + battery system that can move around 50% of its output to other parts of the day only costs $76/MWh
☀️ $43 solar
