Almost 70 per cent of people surveyed for a new poll believe the UK’s major energy companies should be nationalised.

In the survey conducted by research firm ComRes, 69 per cent of respondents backed nationalisation of big energy firms, 77 per cent thought energy prices were set unfairly and 67 per cent were supportive of having wind farms in their area.

Britain’s 12 regional electricity supply companies were privatised in 1990. Today the market is dominated by six private utilites – British Gas, EDF, E.ON, npower, Scottish Power and SSE – who control more than 95 per cent of the sector.

The news that 67 per cent of those polled backed wind farms will please Energy Secretary Ed Davey, who told a meeting in Parliament this week: “The future is bright for renewables in the UK. We have the public on our side – we are taking the public with us.”
