At the same time, Mr Bratland wants the power output of each turbine to be raised to perhaps 6MW, and he wants it all to be cheaper than it is today.

Because the output of a wind turbine also tends to increase proportionally with its distance from barriers such as trees or buildings, the most productive -- and cost-effective -- turbines sit atop tall towers erected on an acre or more of open land.

The 10 megawatts of power that will be generated by the Sound of Islay turbine farm pales into insignificance when compared to the output of a large nuclear or coal power station, which according to American hydro energy non-profit the Ocean Energy Council, can produce up to 100 times as much electricity.

Assuming a rated capacity per turbine of 5 MW, and a capacity factor (actual output) of 30%, we have 1.5 MW for each.

The output is a hot, high-pressure mix of steam and CO2 that powers a turbine.

The UBS report explains that while nuclear energy has suffered a powerful blow, and it is not clear when and how it will get back on its feet, GE will benefit, despite having built the generators, as its strong gas turbine business, along with its smaller renewable portfolio, will step in to cover the output gap generated from a diminishing inventory of nuclear power plants.
