Labour’s Energy Secretary told us that switching to wind and solar would slash the nation’s energy bills by £300 by 2030. That’s since been exposed as a lie.

Now, someone who actually understands energy pricing has done the sums, and it’s bad news for Ed.

It’s also bad news for the rest of us.

As suspected, Miliband does not live on planet earth. Heaven knows which galaxy he gets his maths from.

While he’s right to boost domestic UK wind, solar and nuclear output, he’s wrong about almost everything else.

His Clean Power 2030 plan won’t save us money. Instead, it will add an eye-watering £25billion a year to the cost of electricity.

That’s a staggering extra £900 per household. Which is £1,200 more than the saving Labour claimed we’d bag during its election campaign.

All Governments fiddle with numbers. The Tories did it often enough but Labour has taken it to a new level.

We can’t trust a thing Chancellor Rachel Reeves puts out there. And when Keir Starmer promised to ramp up military spending to stand up to Russia’s Vladimir Putin, he indulged in dodgy bookkeeping, too.

Neither can hold a candle to Miliband.

Which, by the way, we should all be stocking up on in case of blackouts. Unless Starmer fires him this Spring, as rumoured.

Miliband’s fantasy economics won’t save the planet. And they won’t save us money. Instead, they’ll hammer households, cripple businesses and wreck our energy security.

Professor Gordon Hughes crunched the numbers. He’s one of the UK’s leading energy experts.

His forensic analysis lays bare the sheer scale of Miliband’s recklessness, which will push up costs across our electricity system, from generation to capacity levies to system balancing.

Worse still, as carbon emissions permits become scarcer, these costs will only go in one direction. That’s right. Up.

Professor Hughes says: “Miliband’s plan is clearly unaffordable.”

He’s not the only one to pull Miliband’s plans apart. Even Tony Blair has done it.

No wonder Miliband has never come up with figures of his own.

His predecessor, Claire Coutinho, had the sense to commission a similar costing exercise. Rather than face the truth, Miliband cancelled it.

Andrew Montford, director of Net Zero Watch, called for Keir Starmer put a stop to Miliband’s madness or risk “disaster for the UK economy.”

We can’t afford daydreamers. Not with Putin on the rampage.

We need to spend billions more on defence and energy security, not waste it on unproven carbon capture schemes and a bloated Great British Energy quango.

So what should Britain do instead? We can and should boost renewables investment but sensibly, affordably.

That means keeping our oil and gas fields open, not shutting them down as he’s been doing.

All that does is drive up our costs as we import fossil fuels from elsewhere, imperilling our energy security and offshoring our carbon emissions.

These days we can’t even rely on Norway for our gas, let alone the usual dodgy dictators we’re in hock to.

Miliband’s utopian schemes sound lovely at Labour conference podiums, but they don’t work in the real world.

The next Energy Secretary needs to live in reality, not Miliband’s fantasy land.
