Britain wasted £649m already this year powering down wind farms as there is not enough grid capacity to send renewable energy where it is needed, utility finds

The UK’s solar farms and rooftops generated more electricity than ever before in the first five months of 2025, as the country enjoyed its sunniest spring on record.

There is little middle ground in the battle over zonal pricing – and the energy secretary has only months to settle dispute

Just seen this and though it was worth sharing here.

Previous record was 21.81GW - at time of posting we're generating 21.85GW and rising

We've been counting down to this for years now and we're finally on the other side of coal power. Great! 🥳

Update: it produced its last energy on 30th Sept and now the uk is officially coal-free :D

Plans for a £200m green energy park, which could create 4,500 jobs, have been given the green light.

Yorkshire Energy Park, on the site of the former Hedon Aerodrome, to the east of Hull, is set to focus on renewable energy, battery storage, state-of-the-art digital infrastructure and research and development. The proposal, for land allocated to the wider Humber Freeport scheme, was approved by Hull City Council's ruling cabinet.

Households are set to learn that their energy bills will rise again from January as hopes for relief from the cost-of-living crisis are put on hold.

Ofgem will announce its latest price cap on Thursday, with energy consultancy Cornwall Insight predicting it will increase from the current £1,834 for a typical dual fuel household to £1,931 – a 5% jump to take effect from January to March.

The forecasts suggest that the typical bill will then fall to £1,853 from the start of April, but will not drop below today’s level until July next year.

...

Dr Craig Lowrey, principal consultant at Cornwall Insight, said: “An unstable wholesale energy market, coupled with the UK’s reliance on energy imports, makes it inevitable that energy bills will rise from current levels.

“This leaves households facing yet another winter with bills hundreds of pounds higher than pre-pandemic levels, and affordable fixed deals few and far between.”

...

“While we continue to advocate for immediate targeted support for vulnerable consumers, it is evident that the only enduring solution lies in transitioning the UK away from the influence of global energy prices towards sustainable, domestically sourced energy.”

Other countries are using the UK as an excuse for pressing ahead with fossil fuel projects despite their climate commitments, according to Adair Turner, the first chair of the Committee on Climate Change and a former head of the CBI.

Lord Turner told the Guardian that he had “literally been involved in discussions” in China and India where UK decisions had been given as a reason for not moving faster on the climate.

“I can tell you that [the Cumbrian coalmine] was a disaster globally, and in China and India, where I was engaged in debates [on reducing greenhouse gas emissions], I have had people say ‘yeah, but you’re building a new coalmine in the UK’,” he said.

“So that was a disaster for our reputation, and it provides arguments for the people within government or within interest groups in China and India to say ‘oh look, the UK is supposedly committed to net zero, but it’s not serious, it’s building a new coalmine’. And the same occurs with new oil and gas fields in the North Sea.”

Turner is now chair of the Energy Transitions Commission (ETC), a thinktank that on Thursday published a report that says the production of and demand for fossil fuels must be reduced rapidly, and that this is achievable. “Unabated” fossil fuel use must be phased out, and there is only limited scope for the use of carbon capture and storage (CCS), the report finds.

Automated floating factories that manufacture green versions of petrol or diesel could soon be in operation thanks to pioneering work at the University of Cambridge. The revolutionary system would produce a net-zero fuel that would burn without creating fossil-derived emissions of carbon dioxide, say researchers.

The Cambridge project is based on a floating artificial leaf which has been developed at the university and which can turn sunlight, water and carbon dioxide into synthetic fuel. The group believe these thin, flexible devices could one day be exploited on a industrial scale.

“Solar panels are excellent at generating electricity and are making a great contribution to the world reaching its net zero aspirations,” said Erwin Reisner, the professor of energy and sustainability at Cambridge University. “But using sunlight to make non-fossil fuels that could be burned by cars or ships takes things a stage further.”

Reisner and his colleagues envisage exploiting the technology to build carpets of artificial leaves that would float on lakes and river estuaries, and use sunlight to convert water and carbon dioxide into the components of petrol and other fuels. “The crucial point is that we are not decarbonising the economy through techniques like these,” Reisner said. “Carbon is still a key component. What we are doing is to ‘defossilise’ the economy. We will no longer be burning ancient sources of carbon – coal, oil and gas – and adding greenhouse gases to the atmosphere, a process that is doing so much damage at present.”

Wind conclusions:

The authors give three reasons for their discrepancy with MacKay’s estimates.

• Improved fixed turbine technologies. MacKay described all waters deeper than 30 metres as “not economically feasible”. But fixed turbines could soon be commercially feasible to around 80 metres of depth.

• Floating offshore turbines. The advent of floating turbines means that these can extend into much deeper waters. Note that O’Callaghan et al. (2023) already account for many other competing uses such as fishing areas, military zones, shipping routes, and low-wind areas.

• Improved social and political support. O’Callaghan et al. (2023) assume there is less public resistance to offshore wind, which seems appropriate.

Solar conclusions:

What are the major differences to MacKay?

• Lower cost: the price of solar PV has fallen by 90% in the last decade. MacKay’s main concern was it was too expensive: this is not the case today.

• Improved cell efficiency: MacKay used a cell efficiency of 10%, and thought an efficiency of 30% would be “quite remarkable”. Last year, Fraunhofer ISE achieved 47.6%. Efficiencies greater than 30% have also been achieved using perovskite solar cells. O’Callaghan uses a cell efficiency of 25%. See the footnote for a chart showing the differences in efficiency over time.7

• Combined use with agriculture: MacKay assumed an inherent trade-off between agricultural land and solar. He thought the Brits would never give up farmland for solar panels. But this trade-off does not always exist: there are now a range of projects where solar and agriculture work in tandem (‘agrivoltaics’).

The well was drilled but never fracked - leaving the site owners, Third Energy, with a deep hole in the ground.

Tom Heap with Steve Mason and Russell Hoare at the once highly-contested proposed fracking site Its managing director, Russell Hoare, showed me the well and explained its second life. They are even re-using the two metre-high gas valve which caps the hole.

"This is the actual well that was drilled for fracking and it's about 3,000 metres deep, but the protesters were successful, and Steve was successful, in stopping that operation.

"But it's perfect for testing geothermal energy. There's hot water at the bottom. All we're doing is bringing it to the surface."

...

Once commercially exploited, they reckon this well could supply 300 homes, so we would need a lot more deep drilling to keep Britain warm.

Gas to geothermal conversion company, CeraPhi, thinks there are 680 wells in the UK ripe for conversion together with millions around the world, and that new wells can be sunk cheaply enough to expand further.

Such potential provokes interest. While we are on the site, chief executive Karl Farrow is showing around a group of academics and industry players.

They've had more than 100 such visitors in the past month.

Karl told me: "Wells at the end of life can be repurposed and reused for energy.

And you can have your say via public consultation starting today

An old coal mine has been providing an English town with green energy for the last six months.

The ground-breaking project in Gateshead is using the warm water that has filled the tunnels to heat hundreds of homes and businesses in the former coalfield community.

Hailed a success, the UK’s first large-scale network shows the huge potential to be found in the nation’s sprawling warren of old mining tunnels, which sit beneath roughly a quarter of homes.

The world's largest offshore wind farm has started producing electricity for the first time.

Power from the first turbine at the Dogger Bank project, which is construction in the North Sea, is now being sent to the UK's national grid.

In total 277 turbines will be powered-up at the location, situated between 81 and 124 miles (130-200km) off the Yorkshire coast.

The wind farm is due for completion in 2026.

...

Each rotation of the 107m (351ft) long blades on Dogger Bank's first operational turbine can produce enough clean energy to power an average British home for two days, SSE Renewables said.

Once complete, Dogger Bank's offshore turbines are expected to generate 3.6GW of power - enough for six million UK homes.

Rishi Sunak plans to restrict the installation of solar panels on swathes of English farmland, which climate campaigners say will raise bills and put the UK’s energy security at risk.

Last year, then prime minister Liz Truss attempted to block solar from most of the country’s farmland. The plans were deeply controversial and unpopular, and were dropped when she left office.

However, solar panels in the countryside are disliked by many rural Conservative MPs, and the Observer can reveal that Sunak and environment secretary Thérèse Coffey have revived plans to put new restrictions on this form of cheap renewable energy.

Small and medium-sized enterprises (SMEs) at Mildenhall Industrial Park in West Suffolk have reported reductions in their energy bills, ranging from 20% to as much as 90%, thanks to a peer-to-peer energy trading initiative.

West Suffolk Council and Manchester-based deeptech company UrbanChain have partnered to establish a local green energy market.

Peer-to-peer energy trading enables individuals and businesses to directly buy and sell electricity.

West Suffolk Council has proactively invested in renewable energy infrastructure, with 272kW of solar PV installations on ten commercial buildings within Mildenhall Industrial Estate and ownership of a nearby 12MW solar farm.

By participating in UrbanChain’s peer-to-peer energy exchange, the council’s renewable generators have seen returns at least 35% higher than prevailing market rates.

The consumption of electricity in the UK has reached its lowest levels since the second quarter of 2020, a period marked by the initial Covid-19 lockdown, which significantly curtailed energy demand.

According to government analysis, this decline in electricity consumption is evident across all sectors, with the domestic sector experiencing the most significant reduction, down by 7.7% to 20.4TWh.

This continued trend of decreased consumption aligns with the backdrop of increasing household expenses, including rising energy costs.

In addition, there has been a substantial decrease in the demand for natural gas, with a 13% during the second quarter of 2023 compared to the same period in 2022.

The total final consumption of gas also witnessed a decline of 7.5%, reflecting reduced gas demand across all sectors.

Among these sectors, the domestic sector saw the most substantial decline, down by 9.3% compared to the same period in the previous year.
