Tories and Reform use the steel crisis to knock clean energy. They’re wrong: it will secure all our futures| Ed Miliband

The argument for a green power transition is not just one of climate breakdown but social justice and national security

• Miliband in blistering attack on Farage’s UK net zero ‘nonsense and lies’

The world feels more uncertain and unpredictable just now than at any time in my political lifetime. For Britain – in our values, our approach and our consistency – we owe it to today’s and future generations to be the port in the storm. Nowhere is that more true than on energy and climate. The decisions we take today will shape not just the years ahead but the generations ahead.

That is why it is so important that Keir Starmer set out more than three years ago his mission for Britain to become a clean energy superpower. It is even more relevant and important today than it was back then. And he has rightly shown a resolute determination to stick to it. The argument for a clean power system by 2030 is based on what happened to Britain’s families and businesses following Russia’s invasion of Ukraine. Our exposure to fossil fuels meant that, as those markets went into meltdown and prices rocketed, family, business and public finances were devastated. The cost of living impacts caused back then still stalk families today.
