We tend to think of batteries as the ones in our phones. But the real shift is happening at grid scale.
Utility-scale “mega batteries” now have hundreds of millions of times the capacity of a smartphone battery.
Costs are down ~40% since 2024, and capacity in 2024 was 12x higher than in 2020.

Nearly 5GW of solar contracted in UK govt auction. Biggest ever in capacity and confirms solar as the cheapest power in Britain. More solar = lower bills.
BREAKING: UK govt auction secures 4.9GW new solar at £65/MWh and 1.3GW new onshore wind at £72/MWh, 13% and 21% below the price cap respectively.
All due online by 2029.

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.

Lost to history now, but 35 years ago (?!) the then UK govt launched a £10m campaign "declaring war on wasted heating and lighting around the home".
The campaign included an advertising campaign:
"Global warming. We have been warned."
