I've got an interesting link here:
http://www.dailymail.co.uk/news/article-1315711/Wind-farm-power-twice-costly-gas-coal.html
It is a news article by the Daily Mail, who are anti-wind. They are criticising offshore wind power, saying that it costs 15p/unit, more than oil/gas (8p/unit) and nuclear (10p/unit). But then they say "A unit of electricity from an onshore wind turbine costs 9p, the report says."
So an anti-wind newspaper concedes that onshore wind electricity is cheaper than nuclear!
While renewable energy is not always the cheapest energy available, it isn't always unviable without government subsidy.
