Follow OceanWise on a mental voyage from an offshore wind turbine, through the cables, transformers, and converters of a wind farm, and into the living room. Gain a graphic overview of where the greatest energy losses occur.

That which is saved is earned! This old saying applies to renewable energy as well. When following the energy’s path in the 3 MW model WTG production in the illustration, up to 15% of the produced energy disappears during the trip. Converting the energy from one voltage type to another (AC /DC), transforming the energy from one voltage to another (for instance, 400 kV to 150 kV), and transporting the energy in cables over long distances all contribute to this loss.

As you can see in the concluding diagram (Distribution of losses), the calculated loss amounts to 14.8% of the annual energy production (AEP), that this model is based upon: The diagram shows how 55% of these losses take place in the transmission of energy through the cables, 21% in the conversion of energy (HVDC converters), and 24% in the transformation of energy (transformers).
