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.

Generator’s shares rise as regulator finds no evidence of misleading statements about fuel’s sustainability

The City watchdog has closed an investigation into the owner of the Drax power plant after an almost 10-month review into whether the company’s sustainability claims mislead shareholders.

The Financial Conduct Authority said it had “reviewed thousands of pages” of “complex material” relating to the company’s sourcing of wood pellets for the Drax power plant in Selby, North Yorkshire, but “did not find evidence that justified any further action”.

The net zero economy is booming, so claims that prosperity depends on oil and gas are bunkum – unless you’re a Reform backer with fossil fuel interests, of course

Really? You want to destroy a million jobs? Vote Reform UK for mass unemployment: is that your pitch? Hammer these questions home whenever you meet a supporter of the party. Or, for that matter, a Conservative, as their party now takes an almost identical line.

The figures are stark. They were compiled not by Just Stop Oil or the Green party, but by that bastion of conservatism, the Confederation of British Industry. They show that the net zero economy now directly employs more than 300,000 full-time workers, while supporting the jobs of 1.1 million. The net zero sector is worth £100bn to the UK already, and is likely to grow by hundreds of billions more. The rest of the green economy directly employs a further 600,000.

The 700 projects include wind and solar farms, battery storage, gas and hydro plans

More than half the renewable energy projects needed to meet the government’s clean power targets by 2030 are now able to plug into the electricity grid after years of delay, according to the system operator.

The National Energy System Operator (Neso) has offered more than 700 clean energy projects in Great Britain a grid connection date since the start of the year, after a two-year process to unblock a bottleneck that threatened to delay projects into the 2030s.

Government plan to de-link gas and electricity prices aims to reduce bills for consumers after global surge in prices

Households in England, Scotland and Wales could save nearly £200 a year on their energy bills if the government stepped into the market to act as the sole buyer of electricity, according to a thinktank.

The research found that public procurement of electricity, meaning the government would become the “single buyer” of power before it is resold to consumers, could shave billions of pounds from electricity prices.

While Westminster’s attention is focused on Andy Burnham and Makerfield, another pivotal byelection is taking place in Scotland’s north-east

The coming byelection in Makerfield, from where Andy Burnham aspires to make rapid progress towards Downing Street, is perhaps the most consequential in British political history. But the decision by the Scottish National party’s former Westminster leader, Stephen Flynn, to relocate to Holyrood means that another pivotal contest is taking place more than 350 miles to the north. If Makerfield is a test case for Mr Burnham and Labour’s ability to see off Reform UK, Mr Flynn’s old constituency of Aberdeen South is on the frontline of the increasingly fraught politics of North Sea oil.

Labour, despite finishing second in the 2024 general election thanks largely to anti-Tory tactical voting, will not be expecting much this time round. The ramifications of Donald Trump’s reckless war in Iran have exposed Britain’s ongoing vulnerability to fossil-fuel-related energy shocks, highlighting the practical benefits of moving to a green economy. But the knock-on effects of the closure of the strait of Hormuz have also been a gift for the Scottish Conservatives and Reform, who are framing the byelection as a local referendum on reviving oil and gas production beyond Westminster-imposed limits.

Labour leadership hopeful says NI reduction for firms could ‘incentivise’ hiring, particularly of younger people

Wes Streeting has backed calls for national insurance cuts for businesses, and for the government to drill for oil and gas in the North Sea.

The former health secretary and potential Labour leadership candidate told the Sunday Times there should be a “targeted reduction” of employers’ national insurance contribution as a way to “actively incentivise” hiring, particularly of young people.

As summers become hotter, air conditioner sales are booming. If you’re looking to invest, here’s what to consider

When a heatwave struck the UK this week, Jon Connorton, a software developer, began monitoring temperatures inside his east Hampshire terrace house. With some rooms reaching close to 40C, it was time to deploy the air conditioner. “We just wheel it out in emergencies,” he said. “We were having trouble sleeping.”

Connorton and his wife have a portable air conditioner. These plug-in devices cool interior air by removing heat from it and blowing that heat outside, typically via a large hose slung from a window or door.

Energy specialists say abandoning net zero and increasing oil and gas drilling would cause more instability for Britons

• UK politics live – latest updates

Abandoning net zero and drilling for more oil and gas in the North Sea would be a massive setback for the UK and would not help the economy, leading experts have said in response to claims by the former prime minister Tony Blair.

“This is a bizarre intervention to make during the worst May heatwave on record and when the Iran crisis is providing yet more evidence of the enormous costs of oil and gas,” said Ed Matthew, the UK programme director at the E3G thinktank. “Clean energy is cheaper energy – it protects our bills from prices skyrocketing, its running costs are virtually zero, and it doesn’t cause climate change which threatens economic collapse ... The government should ignore Blair’s ideological nonsense and focus on what works.”
