Nuclear, wind and renewable debate: Bennett and Dorries

An offshore wind farm off the Cumbrian coast in the Irish Sea starts generating electricity for the first time on Tuesday and will later have more than 100 turbines, with enough electricity for almost 300,000 homes.
Green Party leader Natalie Bennett said renewable energy costs more, but gave a "reliable energy source that we know of the cost of", as she spoke about green taxes and insulating homes.
But Conservative MP, Nadine Dorries, said Britain was a tiny island, and people did not want "our skyline blighted by these bird-munching turbines", as she called for investment in nuclear power and fusion power and criticised EU directives.
