The findings came in a poll of 1,931 adults carried out by market research firm MORI for UK energy company EDF Energy. Thirty-nine per cent agreed that planning regulations should be changed to make it easier to build nuclear power stations on the same sites as old ones.
A further 57 per cent agreed that the government should relax regulations to make it easier to build wind farms. Seventy-two per cent of respondents said they would support onshore proposals and 78 per cent would support offshore schemes.
EDF Energy chief executive Vincent de Rivaz said: "It is vital to maintain a diverse energy mix in the future."
