We would like to hear from people who have recently installed renewable energy sources in their home, or considered doing so

Great Britain has recorded more new solar power installations in the first half of this year than in any six-month period since 2011, with most of the new panels going onto household rooftops rather than large-scale solar farms.

The government’s data also shows a rise in households turning to other low-carbon technology: applications to the boiler upgrade scheme, which offers grants for replacing gas boilers with greener alternatives, reached 4,512 last month – up 21% on June last year – with demand for heat pumps expected to climb further in the months ahead.

Boom in solar farms and home installations in first half of 2026 began shortly after start of US-Israel war against Iran

Great Britain has recorded more new solar power installations in the first half of this year than in any six-month period since 2011, as households turn to rooftop panels to help cut their energy bills.

An analysis of the government’s official figures shows that Great Britain added 142,536 solar installations in the first six months of the year, putting it on track to top last year’s record solar additions.

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.

Drew Baglino spent nearly two decades building Tesla’s batteries, motors, and power electronics. Now the former Tesla SVP is quietly building the one home energy product Tesla talked up for years and never shipped: a residential heat pump.

His startup, Sadi Thermal Machines, is a direct bet on an idea Tesla floated openly in 2022 — before the company reoriented itself around humanoid robots and robotaxis.
