Farms and rooftop panels contribute 14.4% to the grid – and figures reveal a surge in new installations
Solar energy supplied more power to Great Britain’s grid in July than in any previous month as households turned to rooftop panels to cut their energy bills.
Solar farms and rooftop panels provided 14.4% of the country’s electricity after some parts of the UK recorded almost twice the average sunshine hours for the time of year.

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.
Organised campaigns against wind and solar energy have proved “extremely effective” in undermining community support for renewable energy but enthusiasm for electric vehicles has jumped after Donald Trump’s attack on Iran, according to a detailed snapshot of Australian attitudes to the clean energy transition.
The survey found levels of “deep support” for clean technologies were highest for home batteries and rooftop solar and also improving for major infrastructure projects such as transmission lines, which have been a target for critics of renewables.
Queensland and the Northern Territory have rejected the federal government’s plans to mandate that AI datacentres use renewable power, rubbishing Anthony Albanese’s proposals to regulate the booming technology as “underdeveloped ideas that hand increased power to Canberra”.
The latest federal-state stoush on energy comes as S&P Global, the economic rating agency, warns that power use from datacentres could rise five-fold by 2035 to 10% of Australia’s total consumption, and that a mismatch between delivery timelines for datacentres and renewable projects could lead to energy bills skyrocketing.
Law change means renters and flat owners may be able to cut bills as energy costs soar amid Iran war
British households will be able to buy plug-in solar panels later this summer after the government changed the law so the UK’s biggest retailers could bring them to market for the first time.
People across the country will be able to join the millions across Europe generating their own electricity using “balcony solar panels” from 27 August, according to legislation passed last week.
Tories, Reform, fossil fuel industry and some in his party lined up against decarbonisation target as energy secretary
“Whenever the Labour party feels a bit sad,” according to one close observer of the current government, speaking some months ago, “they wheel out Ed Miliband to talk about rooftop solar.”
It might not have been literally true, but it often felt during Keir Starmer’s premiership as if energy secretary Miliband brought the sun. Unfailingly upbeat, with a simple message that was understandable to voters, he had a clear mission – to decarbonise the UK’s power sector by 2030 – that was seen to be progressing fast.
From Nevada to Manchester, developers are trialling innovative solutions to clean energy’s biggest challenge
In the deserts of the United Arab Emirates a sprawling clean energy project, stretching across an area roughly the size of 12,600 football fields, will play host to a breakthrough allowing solar energy to power the equivalent of half a million homes through the night.
The Gulf state has been steadily combining 5.2GW of solar power capacity with 19GWh of battery storage to create the largest battery scheme in the world.

Australia is a world leader in household solar, but the benefits of rooftop renewables are unevenly distributed – and many of the 2.5 million people living in apartments or units are missing out.
About 39% of Australians living in detached or semi-detached houses have solar, compared with 6% of those in apartments or units, research by Energy Consumers Australia (ECA) finds. A gap also exists in the take-up of batteries, installed in 7% of houses but only in 3% of apartments or units.
The predicted £264bn cost by 2050 could be even higher, plus renewables avoid a far higher total of emissions than can be captured, writes Andrew Boswell, while Simon Oldridge calls out vested interests
Prof Myles Allen and colleagues, in their letter (12 July) on carbon capture and storage (CCS), propose licensing gasfields on condition that producers store an increasing proportion of “the carbon dioxide their products generate”. Their proposal only considers CO2. Methane is excluded by choice although it leaks throughout global fossil-fuel supply chains, including during extraction, processing, liquefaction and shipping.
A growing academic literature, supported by satellite observations of major methane plumes, shows that these emissions can be very substantial, and are the dominant near-term climate impact for gas supplied as liquefied natural gas.
“Burnham has been very quiet about the climate [crisis] so far,” says Chris Venables, an environmental campaigner and fellow at the Green Alliance thinktank. “I don’t think [it] is at the forefront of his mind, but that does not mean he will water down this agenda.”
Claims by the Coalition and One Nation that abandoning a net zero climate target would bring down power prices are contradicted in a new CSIRO report on the costs of generating electricity.
Generation costs will probably rise after 2030 regardless of Australia’s policy on net zero, according to the CSIRO’s annual GenCost report, but prices should then stabilise at levels below recent price spikes.
As government agencies go, the US Nuclear Regulatory Commission has left a lot to be desired, often operating less like a government watchdog and more as an industry partner. There’s fee recovery, for example, which effectively mandates the industry pay its own regulators’ salary, as well as the NRC’s habit of trusting voluntary leak reports from reactor operators, not to mention its history of hiding internal safety data to protect its reputation.
As if those deficiencies weren’t bad enough, president Donald Trump is now stripping what’s left of the commission’s mandate down to the bone. Last week, the NRC proposed a bold amendment to its long-standing nuclear safety principles: deleting a line requiring nuclear plant operators to keep radiation exposure “as low as is reasonably achievable.”
According to the Hill, the NRC justifies the move by saying it will remove “unnecessary ambiguity.” But critics say this rule is the whole reason energy companies bother keeping radiation levels as low as possible in the first place.
“Facility owners felt like… ALARA [as low as reasonably achievable] was forcing them to go well below the allowable radiation limits and spend a lot of money to do that,” director of nuclear power safety at the Union of Concerned Scientists Edwin Lyman told the Hill. “This is opening the door for sloppier practices,” Lyman continued, and “worse management.”
It gets worse. Also per the Hill, the NRC likewise announced plans to significantly weaken its approach to the National Environmental Policy Act, a foundational piece of legislation dating back to 1970. On Wednesday, the NRC said it wants to gut draft environmental reviews entirely — which, in practice, means kneecapping the public’s chance to weigh in before a reactor gets the green light.
If that weren’t enough, the commission also wants to wash its hands of its mandate to review basic environmental nuisances like noise, dust, and air pollution associated with nuclear facilities. That’s if they even do a review in the first place, as the proposed changes would exempt certain existing reactors, and even new reactors from regular inspection altogether, the Hill reports.
The proposed changes come just a few months after the US Department of Energy began stripping safety regulations that limited nuclear workers’ exposure to radiation. In effect, these changes allow energy companies to speed up productivity, unlocking higher profits at their workers’ expense.
The timing of it all is hard to overstate: with several new nuclear reactors gearing up for operations throughout the US, it’s clear the Trump administration is doing all it can to fast-track incoming nuclear facilities, consequences be damned.
Timing of Devon switchoff ‘could not be worse’, says board, as members face an estimated £2m in lost revenue
Britain’s biggest community solar project has been forced to shut for the duration of its first summer by the government’s energy system operator to avoid overloading the local grid with renewable energy.
The north Devon solar farm was ordered to shut weeks before record high temperatures across Europe led to power supply warnings, due to concerns that the large amount of rooftop solar in the area could destabilise the power grid by triggering a “thermal overload”.

Researchers on Beaver Island, in Lake Michigan, are trying to find a more reliable form of power using local resources
Beaver Island sits in the middle of the northernmost end of Lake Michigan, about 70 miles from the maritime border with Canada. The forested island, just a little bigger than San Francisco in size, is a popular summer destination for tourists and home to about 600 permanent residents. Getting there requires a boat or plane ride.
Getting electricity to the island is not as easy. Power comes from mainland Michigan through cables that cross roughly 30 miles of lake bed. Outages are common during extreme weather, or when there are problems with the sensitive wires. The devastating ice storm that walloped the state last year knocked out power to the island for weeks.
There are far better ways to tackle climate breakdown, but successive governments have chosen to listen to the fossil fuel companies instead
The new prime minister will be looking for money? Well, here’s £21.7bn lying on the ground. The government could cancel its deranged, disastrous carbon capture and storage (CCS) programme at no cost to public welfare: in fact, it would greatly reduce the harm we will suffer.
