MADRID/FRANKFURT (Reuters) - A boom in offshore wind power sparked by the European Union's espousal of the technology runs the risk of becoming a bubble unless installation, running and repair costs are more clearly defined.
As major European countries backpedal over state aid for so called "immature technology" like solar power, other EU members are charging into offshore wind, despite cost estimates being notoriously unreliable after nearly two decades of working wind farms in European waters.
