Wind power from the sea: economic efficiency tops all other energy sources
The entire life cycle of the turbines was considered, from installation to grid connection, operation and maintenance through to dismantling. The comprehensive analysis also revealed other important characteristics that could have an impact on other areas.
Particularly noteworthy is the sharp drop in electricity costs, which are usually calculated in megawatt hours. When the expansion of offshore wind farms began, the megawatt hour £160, which would correspond to US-¢20 per kilowatt hour. Taxes, grid fees and other charges are added to this.
Currently, however, the price is only £44, or a quarter. If inflation were factored in, the fall in costs would be even more drastic. This means that you currently pay US-¢5 for a kilowatt hour of offshore wind power fed into the grid.
In comparison, the UK government has committed to paying £92.50 per megawatt hour fed into the grid by the new nuclear power plant "Hinkley Point C" - more than twice as much.
In addition to the price, the robustness of the wind turbines was also emphasized. The existing wind farms have proven to be very resistant to earthquakes and associated tsunamis in particular. In addition, each turbine can work on its own, so the failure of one part does not mean a complete breakdown - quite the opposite for individual, large power plants.
This in turn appears to be particularly valuable in combination with nuclear power plants. For example, the researchers were able to show that the Fukushima disaster could have been prevented if offshore wind turbines had been available for emergency power - even if some had been damaged in the tsunami that caused it.
And a further calculation demonstrates the advantages of wind turbines: Not only does wind blow for free to begin with. It blows so strongly around the globe that the global electricity production of all possible power plants could be covered 18-fold by wind turbines.
