A new poll conducted in the wake of the Fukushima disaster found that 37% of people surveyed would now oppose new nuclear in the UK.
And 44% are worried about the safety of UK nuclear plants.
The poll, conducted by GfK NOP for Friends of the Earth, found that more than 75% of respondents believed the government should be investing in renewables rather than nuclear.
Friends of the Earth’s director of policy and pampaigns Craig Bennett said: “While the UK is not at risk of major earthquakes and tsunamis, our nuclear stations are vulnerable to sea surges, rising sea levels and terrorist attacks.
“We can keep the lights on and cut the UK’s reliance on oil and nuclear by building a safe and secure energy future based on cutting energy waste and harnessing our vast renewable power potential.
“This poll shows that the government’s plans for a major expansion of nuclear power in the UK are out of step with public opinion. People want clean and safe energy – the government needs to urgently refocus its energy policy, starting by improving the weak energy saving measures within its new Energy Bill.”
