“Whereas 300 tonnes of steel in a combined cycle gas turbine can use natural gas to produce a generator with a capacity of 600 MW [i.e. 600 Megawatts or 600 million watts, or 2 thousand Watts per kg of steel] the same kilogram of steel in the nacelle of a wind turbine contributes 2 Watts of capacity, and once the concrete in the plinth and foundation of a wind turbine is included the ratio deteriorates still further.”
