Producing renewable electricity is roughly twice as expensive as generating fossil fuel power, says a Royal Academy of Engineering report published last week.
The cheapest renewable power source is onshore wind at 5.5p/kWh, compared to gas and nuclear generation which only cost 2.3p/kWh.
But the report, produced for the Academy by consultant PB Power, also shows that the cost of fossil fuel generation escalates when the costs of carbon generation are factored in.
