Lanchester Wines in north-east England uses heat from a disused coalmine to maintain wine temperatures and with 23,000 flooded mines in the UK, there’s huge potential for more businesses and homes to follow its lead

Shove them in a fridge, stash them in a cellar – this is how most people store their favourite bottles of wine. But if you have warehouses full of thousands of vintages, you have to think a little differently.

For the last eight winters, Lanchester Wines has used heat from a disused coalmine to maintain ideal storage temperatures at its facilities in the north-east of England, helping to prevent freezing or spoilage.

Apart from effort to electrify, there were geopolitical tensions around climate science and the 1.5C goal at pre-Cop31 climate talks

Electrifying the world – with electric vehicles, electric heating and cooling, and modernised heavy industry – could be the next biggest step towards phasing out fossil fuels, replacing the 80% of global energy that still comes from hydrocarbons. As using electrical energy is much more efficient than combustion, the move would save billions of dollars for consumers and businesses – global energy demand could be halved, according to one estimate.

For decades, electrification has been a nerdish backwater of global climate action. But in the last two weeks, at preparatory talks in Bonn before the forthcoming UN Cop31 climate summit, the subject finally took centre stage.
