Ed Miliband to double down on clean power push and take huge swipe at net zero critics

Some 640,000 hectares of the public estate, including land linked to the railway and the Ministry of Defence, could be used for green energy schemes such as solar panels and wind turbines, he is expected to say.

He is also due to announce plans to break the link between electricity and gas prices to protect households and businesses from gas price spikes.

Mr Miliband will hit back at critics who say his race to Net Zero is harming the country, saying: “We will double down, not back down, on our mission for clean energy."

In his speech, Mr Miliband is expected to outline measures including speeding up the rollout of renewables and electrifying heating and transport to get homes and businesses off fossil fuels.

These include expanding renewables on publicly owned land, including solar panels alongside railway lines, and making it easier for people to install green technology, such as electric vehicle chargers when they do not have driveways.

Speaking at a “national growth debate”, Mr Miliband will answer critics who have pushed a rethink on net zero and more drilling for oil and gas in the North Sea by warning that ignoring two fossil fuel crises in less than five years “would be completely irresponsible”.

Consumers face high prices at the petrol pumps and looming energy bill rises in the next price cap period from July as a result of disruption to global energy markets caused by the US-Israeli war on Iran.

The latest crisis comes three years after the last energy spike prompted by Russia’s invasion of Ukraine.

Key to the plans is breaking the link between gas and electricity prices, with volatile fossil fuel prices setting the cost of wholesale electricity the majority of the time.

Gas plays an outsized role in the cost of electricity in Britain, setting the wholesale price of power around 60 per cent of the time, down from around 90 per cent at the beginning of the decade, despite supplying a much smaller and decreasing share of power.

That is because of the marginal pricing system, in which the most expensive source of energy brought on to the grid to meet demand sets the price for all generators, apart from those on other types of contract.

That price-setting source is often gas, leaving British consumers at the mercy of volatile wholesale gas prices, while delivering a windfall for generators such as nuclear and older renewables that are not on fixed contracts.

The Government is now proposing a voluntary move by “legacy” clean power generators, which supply around a third of Britain’s power, on to fixed-price contracts, with the Treasury expected to provide tax incentives to encourage them to switch.

It is hoped the new contracts will deliver benefits on consumers’ bills over the next 12 months, though officials are not yet able to say what savings could be delivered.

Mr Miliband is expected to tell the Good Growth Foundation event: “As we face the second fossil fuel shock in less than five years, the lesson for our country is clear: The era of fossil fuel security is over, and the era of clean energy security must come of age.

“For Britain and so many other countries, clean energy is now the only route to financial security, energy security and national security.

“While some have said we have gone too far and too fast, I profoundly disagree.

“In response to recent events, our action must now be faster, deeper and more wide-ranging. That is why we will double down not back down on our mission for clean energy.”

The plans include making it easier for people to switch to electric vehicles and heat pumps, getting them off oil and gas, with deregulation to make it easier and quicker to install clean tech.

These include permitted development rights for people to install cross-pavement facilities for on-street charging and making it easier for renters and leaseholders to request and install chargers.

Officials say it will support surging demand for heat pumps, solar panels and electric cars, boosted by the Iran war. Plans to “massively” expand renewables across the public estate, using brownfield land, industrial sites and railway land to host solar panels and wind turbines, could unlock up to 10 gigawatts (10GW) of capacity – powering the equivalent of five million homes – officials say.

There have been calls from the Tories and Reform UK to increase supplies of oil and gas from the North Sea and to bring down bills by scrapping measures to help the UK shift to a “net-zero” clean economy, such as new renewables and heat pump subsidies.

Mr Miliband will say: “To ignore one fossil fuel crisis and carry on with business as usual, as some wanted to do, was wrong.

“To ignore two in less than five years would be completely irresponsible. And it would be even more irresponsible because unlike the twin fossil fuel shocks of the 1970s, there is now a compelling alternative in the form of clean energy.

“An alternative that cannot be disrupted by foreign wars because it comes from our own wind, sun and nuclear resources.”

Holly Brazier Tope, director of politics at the Green Alliance think tank, said: “The Government’s renewed focus on clean energy is a necessary and welcome response to the hard lessons of the latest fossil fuel crisis.

“The Energy Secretary is right to prioritise accelerating electrification and clean power as the surest path to security and long-term economic resilience.”
