Question for written answer E-005787-18
to the Commission
Rule 130

 Subject:  Developing water turbines in France and Europe
 Answer in writing 

France and Europe are lagging behind in the area of water turbines, having given priority to wind turbines.

Nonetheless, a water turbine was recently installed off the island of Ouessant. This will reduce carbon emissions on the island, where electricity is largely provided by electricity generator units that consume 2 million litres of fuel a year. This solution could be suitable for other insular regions, including overseas territories, if conditions are favourable.

Water turbines ensure reliable and predictable production. They generally do little harm to the marine ecosystem: the propellers are rounded, not sharp, they turn slowly and are located in sites where currents are very strong and the development of flora and fauna is restricted.

There are, however, some disadvantages: installing them underwater is complicated. It is not easy to connect them to the electricity network and they are difficult to maintain. In other words, the installation and maintenance of water turbines is very expensive right now.

1. Does the Commission deem the scientific research into water turbines to be sufficient?

2. Will this research allow for significant improvement in the cost-efficiency of water turbines and, as a result, the development of this technology?
