Scotland risks being left behind in the world unless the Government urgently ends its opposition to nuclear energy, a coalition of businesses and campaign groups has warned.

Scotland for Nuclear Energy, launched by campaign groups Nuclear for Scotland and Britain Remade, said Scotland could miss out on jobs and economic growth as other countries invest in new nuclear technology.

While energy is reserved to Westminster, powers over planning has given the SNP an effective veto over nuclear energy – something the party has long opposed but which is backed by Labour and the Tories.

Scotland for Nuclear Energy claimed the country could build on its nuclear heritage to install new nuclear reactors in a move it said would complement, rather than compete with, renewable energy.

Sam Richards, chief executive officer of Britain Remade, said: “Scotland has done brilliantly with renewables, but the wind doesn’t always blow when we need it.

“Nuclear is clean, reliable baseload power that keeps the lights on, stabilises bills and attracts huge investment.

“At a time when countries across Europe are embracing nuclear as a safe, clean and reliable part of the energy mix, the Scottish Government’s refusal to even consider it is deeply irresponsible.

“They should drop their outdated opposition to nuclear power. If they don’t, it will be the people of Scotland that miss out.”

The group said while Scotland still has four registered nuclear sites, only one – Torness nuclear plant – is operation and generating power, providing what it described as “clean power” to two million homes.

It pointed to polling which shows majority support for nuclear energy.

Trudy Morris, chief executive of North Highland Chamber of Commerce, also backed the campaign.

She said: “Here in the north Highlands, we have lived the reality of nuclear energy for decades and the transformative impact of NRS Dounreay on our economy, skills base and communities is impossible to ignore.

“It has supported thousands of high-value jobs, invested in our supply chains and created expertise that continues to benefit the region.

“The chamber supports a mixed energy economy. Renewables are central to Scotland’s future but they work best alongside clean, reliable baseload power.

“With the highest safety standards, nuclear can complement renewables, strengthen energy security, cut emissions and ensure communities like ours continue to share in the economic benefits.”

The Scottish Campaign to Resist the Atomic Menace said nuclear energy was a “distraction”.

Pete Roche, spokesman for the group, said: “As renewable energy-rich Scotland heads towards an election, it is all too predictable that nuclear lobbyists are again arguing that Scotland needs new nuclear power stations.

“They misleadingly present them as cheap, clean and ‘green’ – yet this is as far from the truth as it was 70 years ago when it was promised that nuclear energy would be ‘too cheap to meter’.

“An energy system built around renewables is already happening. Meeting all our needs this way is not just possible but it’s quicker and cheaper without the costly distraction of new nuclear.

“Low-cost renewable energy combined with storage, flexible power to balance the grid and smart local energy systems will make the best use of our incredible renewable resources and engineering know-how.

“Why dilute that by backing eye-wateringly expensive nuclear power stations?”

The Scottish Government has been approached for comment.

Sainsbury’s has launched a range of high protein and “nutrient rich” meals as supermarkets rush to meet soaring demand from customers on weight loss jabs.

The UK’s second-biggest supermarket chain said the new “small but mighty” range had been designed to be “perfectly portioned to support customers with reduced appetites” and meet their protein and fibre requirements.

Each meal contains fewer than 350 calories while being a source of fibre, containing at least 20g of protein and counting towards one of the “five-a-day” portions of fruit and vegetables.

Sainsbury’s said online searches for “high protein” were up 57% year on year and searches for “high protein ready meals” had increased by 300% as it also launched 19 products to meet demand.

The range includes a pesto chicken tortiglioni containing 35g of protein and a beef bolognese tagliatelle containing 33g.

Other products include high protein wraps, salads and sandwiches, porridge pots, cereals and natural yoghurts.

In February, the supermarket will also launch a selection of high protein bakery items including tortilla wraps, flatbreads and buttermilk pancakes.

James Campbell, Sainsbury’s director of fresh product innovation, said: “We understand people have different nutritional needs, appetites and tastes, and that continues to guide how we develop our products.”

Sainsbury’s follows retailers including Ocado, Marks & Spencer, Waitrose and Greggs in advertising new ranges catering for those taking GLP-1 drugs.
