There are few renewable energy policies that do not depend heavily on wind power and wind is certainly at the heart of the most ambitious, the EU's binding target of sourcing 20% of final energy consumption from renewable resources by 2020. As the EU's target for transport is half that for energy consumption as a whole, it follows that the power sector will be required to source a proportion of energy from renewables that is much higher than 20%. According to the European Wind Energy Association, the figure is 35%.rnWithin that, wind will be the largest contributor, accounting for just over one-third of 'green' electricity, suggesting that between 11.6-14.3% of the EU's power will be supplied by wind by 2020, according to the EWEA. This would mean the installation of 180 GW of wind power by 2020, up from 56.535 GW installed in the EU-27 at end-2007, producing about 477 TWh of power. The transport element of the EU plan is also dependent on future scientific advances, for example, that second generation biofuels become commercially available. This uncertainty will put more pressure to achieve in areas that are already within technological reach.
