Households and businesses will have to wait for energy bills to fall significantly because there is “no shortcut” to bringing down prices, the energy minister has told Sky News.

Speaking as Chancellor Rachel Reeves considers ways of easing the pressure on households in next week’s budget, energy minister Michael Shanks conceded that Labour’s election pledge to cut bills by £300 by converting the UK to clean power has not been delivered.

The UK has the second-highest domestic and the highest industrial electricity prices among developed nations, despite renewable sources providing more than 50% of UK electricity last year.

“The truth is, we do have to build that infrastructure in order to remove the volatility of fossil fuels from people’s bills,” Mr Shanks said.

“We obviously hope that that will happen as quickly as possible, but there’s no shortcut to this, and there’s not an easy solution to building the clean power system that brings down bills.”

His comments come amid growing scepticism about the compatibility of cutting bills as well as carbon emissions, and growing evidence that the government’s pursuit of a clean power grid by 2030 is contributing to higher bills.

While wholesale gas prices have fallen from their peak following the Russian invasion of Ukraine in 2022, energy bills remain around 35% higher than before the war, inflated by the rising cost of reducing reliance on fossil fuels.

The price of subsidising offshore wind and building and managing the grid has increased sharply, driven by supply chain inflation and the rising cost of financing major capital projects.

In response, the government has had to increase the maximum price it will pay for offshore wind by more than 10% in the latest renewables auction, and extend price guarantees from 15 years to 20.

The auction concludes early next year, but it’s possible it could see the price of new wind power set higher than the current average wholesale cost of electricity, primarily set by gas.

Renewable subsidies and network costs make up more than a third of bills and are set to grow. The cost of new nuclear power generation will be added to bills from January.

The government has also increased so-called social costs funded through bills, including the warm home discount, a £150 payment made to around six million of the least-affluent households.

Gas remains central to the UK’s power network, with around 50 active gas-fired power stations underpinning an increasingly renewable grid, and is also crucial to pricing.

Because of the way the energy market works, wholesale gas sets the price for all sources of electricity, the majority of the time.

At Connah’s Quay, a gas-fired power station run by the German state-owned energy company Uniper on the Dee estuary in north Wales, four giant turbines, each capable of powering 300,000 homes, are fired up on demand when the grid needs them.

Energy boss: Remove policy costs from bills

Because renewables are intermittent, the UK will need to maintain and pay for a full gas network, even when renewables make up the majority of generation, and we use it a fraction of the time.

“The fundamental problem is we cannot store electricity in very large volumes, and so we have to have these plants ready to generate when customers need it,” says Michael Lewis, chief executive of Uniper.

“You’re paying for hundreds of hours when they are not used, but they’re still there and they’re ready to go at a moment’s notice.”

He agrees that shifting away from gas will ultimately reduce costs, but there are measures the government can take in the short term.

“We have quite a lot of policy costs on our energy bills in the UK, for instance, renewables incentives, a warm home discount and other taxes. If we remove those from energy bills and put them into general taxation, that will have a big dampening effect on energy prices, but fundamentally it is about gas.”

The chancellor is understood to be considering a range of options to cut bills in the short term, including shifting some policy costs and green levies from bills into general taxation, as well as cutting VAT.

Tories and Reform against green energy

Stubbornly high energy bills have already fractured the political consensus on net zero among the major parties.

Under Kemi Badenoch, the Conservatives have reversed a policy introduced by Theresa May. Shadow energy secretary Claire Coutinho, who held the post in the last Conservative government, explained why: “Net zero is now forcing people to make decisions which are making people poorer. And that’s not what people signed up to.

“So when it comes to energy bills, we know that they’re going up over the next five years to pay for green levies.

“We are losing jobs to other countries, industry is going, and that not only is a bad thing for our country, but it also is a bad thing for climate change.”

Reform UK, meanwhile, have made opposition to net zero a central theme.

“No more renewables,” says Reform’s deputy leader Richard Tice. “They’ve been a catastrophe… that’s the reason why we’ve got the highest electricity prices in the developed world because of the scandal and the lies told about renewables.

“They haven’t made our energy cheaper, they haven’t brought down the bills.”

Mr Shanks says his opponents are wrong and insists renewables remain the only long-term choice: “The cost of subsidy is increasing because of the global cost of building things, but it’s still significantly cheaper than it would be to build gas.

“And look, there’s a bigger argument here, that we’re all still paying the price of the volatility of fossil fuels. And in the past 50 years, more than half of the economic shocks this country’s faced have been the direct result of fossil fuel crises across the world.”

The world’s most valuable company has reported another series of expectation-beating results, heading off fears of the AI bubble bursting for now.

Nvidia’s revenue reached $57bn in the three months to October, higher than Wall Street estimates and the company’s own guidance.

That’s up 62% on the same time last year, and has been described by the business as an “outstanding” quarter.

A profit measure called earnings per share was also better than expected at $1.30.

It matters as Nvidia has powered the artificial intelligence (AI) boom through its computer chips, which are key parts in AI chatbots such as ChatGPT.

Nvidia has major tech companies as clients and acts as a good proxy for whether the tens of billions of dollars invested in AI is paying off.

Its chief executive, Jensen Huang, has been described as the Godfather of AI and watch parties were organised for those looking to follow the Wednesday evening announcement.

The company has been a massive beneficiary of the push to put money into AI, with its share price reaching stratospheric highs.

In October, it became the first worth $5trn (£3.83trn), about the size of the German economy, Europe’s largest, and double the UK’s benchmark stock index, the FTSE 100.

What’s been announced?

Revenue from data centres reached a record high of $51.2bn, more than £10bn higher than the three months previous.

The outlook is for continuing strong sales in the final three months of the financial year, as the company forecasts revenue will be roughly $65bn.

Demand for Nvidia products continues to surpass expectations, while the business is “still in the early innings” of AI transitions, its chief financial officer Colette Kress said.

Mr Huang said sales of its blackwell chips are “off the charts” and its cloud graphics processing chips (GPUs) are “sold out”.

Why it matters

Developing AI infrastructure, like the construction of data centres, has been a significant contributor to US economic growth, as measured by gross domestic product (GDP).

A faltering of AI expansion, therefore, impacts the US economy, the world’s largest, which in turn affects the UK and global economies.

Anxiety around the massive valuations tech companies have accrued, on the hope of AI revolutionising the world, is likely to be staved off by the results announcement.

A fall in these tech company valuations could have meant a drop in the value of pension pots or savings.

Just seven dominant tech companies, many of which have borrowed to invest in AI, make up more than a quarter of major US stock index, the S&P 500.

In the last year alone, Nvidia’s share price has risen more than 230%.

Some, including US trader Michael Burry, famous for being played by Christian Bale in the Hollywood film The Big Short, have effectively bet that Nvidia’s share price would fall.

Addressing the topic of an AI bubble, Nvidia’s founder, Mr Huang, said, “From our vantage point, we see something very different”.

What next?

Regardless of the figures released on Wednesday evening, significant market moves were anticipated, given the attention paid to the results and the significance of the company.

Nvidia shares rose as much as 4% in after-hours trading.

The results also boosted the share price of its chip-making competitors like Broadcom and Advanced Micro Devices.

For now, the AI bubble remains intact.

Consumer confidence has tumbled amid rampant speculation about what the chancellor will announce in the budget, figures show.

The British Retail Consortium (BRC) blamed “strong hints” from the government of income tax hikes for the public’s falling expectations of how much they’ll spend over the next three months – even as Christmas beckons.

While a planned increase in income tax rates was scrapped last week, Sir Keir Starmer has refused to rule out freezing income tax thresholds – which the Conservatives argue amounts to a tax rise by stealth because it drags people into paying higher rates even if their wages increase.

BRC chief executive Helen Dickinson said months of uncertainty had “heightened public concern about their own finances and the wider economy”.

Consumer expectations for the state of the economy over the next three months have fallen significantly to minus 44, down from minus 35 in October, according to data from the BRC and Opinium.

Ms Dickinson said action was needed from Rachel Reeves to “bring down the spiralling cost burden facing retailers”, which she said would “keep price rises in check”.

Signs of ‘fragile’ recovery in jobs market

In slightly more encouraging news for Ms Reeves ahead of her statement next Wednesday, new research suggests the jobs market may be on the up.

The Recruitment and Employment Confederation said the number of new job adverts last month was 754,359, up by 2.1% from September, taking the total to more than 1.6 million.

Ms Reeves’s decision to hike national insurance contributions for employers in last year’s budget was blamed for a slowdown in the market, and a rising unemployment rate.

The report said there has been an increase in adverts for medical radiographers, delivery drivers and couriers, and further education teaching professionals.

But it warned the apparent recovery was “fragile”.

Reeves set to back DLR extension

One man looking forward to the budget is Sir Sadiq Khan, who has welcomed reports that London’s DLR is set to be given funding for an extension.

According to the Press Association, the chancellor will back an extension to the Docklands Light Railway to Thamesmead at a cost of £1.7bn – unlocking thousands of new homes.

Thamesmead has been notoriously short of public transport links ever since it was developed in the 1960s.

The plan would see the line extended from Gallions Reach, near London City Airport, and include a new station at Beckton as well as in Thamesmead itself.

Sir Sadiq said the DLR extension “will not only transform travel in a historically under-served part of the capital but also unlock thousands of new jobs and homes, boosting the economy not just locally but nationally”.

It is also expected to unlock land for 25,000 new homes and up to 10,000 new jobs, along with almost £18bn of private investment in the area.
