Warm homes plan would create 50,000 jobs, compared with about 1,100 for Rosebank oilfield, thinktank finds

Insulating Britain’s homes and investing in heat pumps would do more to cut the cost of living, create jobs and boost the UK’s economy than drilling for new oil, research suggests.

The government’s £15bn warm homes plan, currently under threat of cuts as ministers seek budget savings, would slash £1bn a year from household energy bills across the UK, concentrated on those on low incomes, according to research by the thinktank E3G. It would also provide a £1.6bn yearly boost to the economy, and about 50,000 new jobs spread across thousands of small businesses.

Tories plan to scrap low-carbon housebuilding, Greens back new nuclear reactors, and Labour put oil-drilling decisions on hold

New homes could be built without solar panels, heat pumps and high-grade insulation, leading to higher household bills if the Conservative party wins the next general election.

Kemi Badenoch made scrapping the future homes standard (FHS) one of the central planks of her bid to become the next prime minister at the Tory party conference this week.

As the UN gathers, signatories from Bernie Sanders to Yeb Saño issue an open letter calling for clean power for all

• The climate fight has one great ally. You just can’t look at it directly


We the undersigned write this letter out of great fear and great hope.

Over the last few months, we’ve seen the world set ablaze by both war and warming. From the conflict in Iran, which has claimed thousands of lives and disrupted billions more, to the series of ever worsening climate disasters, from wildfires in Europe to collapsing glaciers in Nepal, the world seems to be falling apart exactly when it needs to be coming together.

Rooftop solar alone generates more than half of all power used, as clear sunny days and low demand drive record-breaking surge

Sunshine and wind met 80.4% of demand on Australia’s main power grid on Saturday, setting a new high bar for renewable electricity.

Solar panels on rooftops provided more than half of the power used in the national electricity market, the grid that supplies the eastern states, South Australia and the Australian Capital Territory, for 30 minutes around lunchtime. This was complemented by solar and windfarms, and a small amount of hydro (1%). Fossil fuels, coal and gas, contributed 20%.

With nearly £30m of funding, I’m giving communities power over local energy. They know the gravity of global heating, and they want to be part of the solution

• Andy Burnham: UK must fully commit to reaching net zero by 2050

On the day I became prime minister, I pledged to bring power to every postcode. Today, we begin to make good on that promise in the most literal sense. With nearly £30m of funding for People’s Power projects, communities across every nation of the UK will soon have the chance to build and control their own clean energy supply.

This investment means villages, towns and cities can harness the natural resources around them with solar panels on libraries, publicly owned windfarms, hydro schemes in their rivers, or whatever else works for them. The purpose is to put money back in people’s pockets while giving them a direct role in tackling the climate crisis.

Savings grow as energy prices in Great Britain rise and cost of panel installation falls, analysis finds

Households in Great Britain’s cloudiest regions could still save more than £400 a year on their energy bills by installing rooftop solar panels, research has found.

Rising wholesale energy prices mean the potential savings from a home solar panel system have climbed in recent years, as the cost of installation has continued to fall, leading to increased demand.

Firm urges customers to avoid running washing machines and dishwashers between 6pm and 8pm on Wednesday

• Where in the UK will get the best view of the solar eclipse?

Great Britain’s biggest household energy supplier is calling on its customers to use less electricity this week during the deepest solar eclipse in almost 30 years.

Octopus Energy has urged customers to avoid running washing machines and dishwashers between 6pm and 8pm this Wednesday as the moon is expected to block up to 95% of the sun over parts of Britain.

Move to raise levy on goods made with polysilicon aims to protect domestic US supply chains from China, the major producer

Donald Trump has ordered a new 15% tariff on imported products made of polysilicon, an important ingredient in microchip manufacturing that is primarily produced by China.

The new tariff, which will take effect on 4 December, is aimed at supporting US chip and solar panel supply chains to compete with Beijing on artificial intelligence and energy.

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.

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.

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”.

Thinktank says decoupling electricity from gas prices has also helped shield Spain from hikes caused by Iran war

Spanish households save €10 a month on electricity bills because of wind turbines and solar panels installed in the last five years, a report has found.

Typical energy bills would be 19% more expensive if electricity costs were still as tightly coupled to gas prices as in 2021, according to Ember, a climate thinktank. It found Spain’s “strategic” expansion of renewables since Russia invaded Ukraine in 2022 has shielded Spanish households from the latest rises in fossil fuel prices caused by the Iran war.

Australia is pioneering a revolution in home renewables and battery use, proving what is possible with the right policies

The timing was rich with symbolism. As intense heatwaves pummelled Europe and Asia, and oil markets around the world leapt and sputtered, the two big chimneys of one of Australia’s largest power stations were being demolished. Meanwhile, the Australian energy minister was holding a media conference to hail a fall of up to 10% in the benchmark electricity price in parts of the country.

Quietly, and with surprisingly little fanfare from the rest of the world, Australia is pioneering a revolution in home renewables and battery use, proving what is possible with the right policies. The country was already one of the global leaders in domestic solar power, with panels on one in three homes. It also remains, however, a major contributor to the climate crisis through its vast fossil fuel exports. But it is batteries that are giving Australia a new burst of speed.

More Americans are using small solar panels in their back yards or balconies as a clean way to cut their electric bills

If you feel like your electricity bill just keeps climbing, you aren’t imagining it. Since 2020, US residential energy prices have surged by about 30%, making power the largest household energy expense behind gasoline, according to the US Energy Information Administration.

But for residents like Alex Curtis, the days of feeling powerless against rising costs are coming to an end. Curtis is waging a war on his electric bill, and his new weapon of choice is a lightweight, thin-film solar panel.

The world’s biggest miner has halted or delayed projects to cut vast amounts of emissions and has quietly war-gamed options to push major climate investments in its Western Australian iron ore operations into the next two decades, internal documents show.

An exclusive investigation based on documents leaked to the Guardian and the ABC’s Four Corners can reveal that BHP, one of Australia’s biggest historic emitters, has dumped plans for a facility that could have significantly reduced emissions and has put on ice renewable projects designed to power its iron ore operations in the vast, resource-rich Pilbara region.

Oxfordshire’s Ray Valley Solar already generates clean energy for 7,000 homes, and is now crowdfunding storage to marry daylight with evening demand

Tucked away among hedgerows on a large field between a motorway and the River Ray, one of the UK’s largest community-owned solar parks is hard to spot from the surrounding country lanes.

But the nearly 36,000 solar panels installed on the site are literally a shining example of what can be achieved when a renewable energy project is co-owned by local people.

Decades of complacency cannot be magicked away by drilling in the North Sea – or even by hoping that renewables will quickly power everything

First it was Russia’s full-scale invasion of Ukraine, now it is the blockade of the world’s petroleum artery in the Gulf. For the second time in four years, Britain is facing an energy crisis that has been made much worse because of the absence of preparation by its political leaders.

The fact is that our energy politics were conceived for a world where convulsive, global events were a thing of the past. The notion that it would be difficult to access supplies of oil or liquefied natural gas from the international markets did not figure in the understanding of the politicians and officials who shaped our perilous current moment. But even today, the advocates of energy sovereignty on the left and right appear to lack knowledge, understanding or power over this very foundational matter.
