1. Offshore Wind Farms 07 04 2014

2. An overview…

3. UE VISION FOR 2020 +20 % energetic efficiency -20 % greenhouse gas emissions 20 % of energy from renewable source

4. Power Mix UE 2011 2030 (Forecast) - Annual UE electricity consumption = 3,280 TWh. - Wind power was about 6% (200 TWh) in 2011 - Now (end of 2013) it is 8% (257 TWh).

5. Wind energy in EU Total power installed : 35 GW Wind power installed : 11.2 GW (7 large nuclear power plant) 2013 : 117 GW of wind power

6. Advantage of offshore wind farm More powerful winds, more predictability, less turbulence. Offshore wind blow 40% more often Lower environmental impact: view and noise

7. Power installed in 2012 = 1.6 GW (1/7 of annual wind power installed ). Annual production of energy in 2013 = 23 TWh (0.7 % of UE cons.)

15. UE challenges for offshore

16. Avoided costs of fuel from wind power During 2012 Europe spent €545 billion on importing fossil fuels.

17. 2020 3.4 % electric UE consumption 2030 14 % electric UE consumption 2013 0.7 % electric UE consumption Wind offshore power devolopement

18. Future projects in the short term

19. France wind farms in the year ahead

20. Tendencies for offshore wind energy in Spain Spain are financing several R&D project with the objective of developing floating turbine structure for wind power in deep waters (Eolia and Emerge i.e.) Madrid-based Iberdrola Renewables plans to develop six offshore wind farm projects with an aggregate generation capacity of 3,000 MW at locations off the coasts of the Spanish Atlantic provinces of Cádiz and Huelva and the Mediterranean province of Castellón.
