Support for the onshore wind industry in France has blown hot and cold in recent months, but government backing for offshore was reinforced in April by its decision to award tenders to build offshore wind farms to produce 2 GW of energy. French company Nass&Wind Offshore, is taking full advantage of this momentum and investing in LiDAR (Light Detection and Ranging) measuring devices – a move it believes will give it a competitive advantage when the government decides to release a second offshore tender later this year.

LiDAR is an optical remote sensing technology that Nass&Wind is using to measure the speed of wind and turbulence up to an altitude of 200 metres – higher than the nacelle generally located 100 metres above sea level, says the company. Nass&Wind has now installed two of these devices off the coast of western France to try to accurately determine the power production potential of planned offshore wind farms.

Wind power will be the second biggest contributor to global renewable electricity generation by 2017, according to a ground-breaking report by the International Energy Agency (IEA).

Despite economic uncertainties in many countries, global power generation from renewable sources including wind will increase by more than 40% to almost 6,400 terawatt hours (TWh) – roughly the equivalent of one-and-a-half times current electricity production in the US, predicts the Medium-Term Renewable Energy Market Report 2012.

This is the first time the IEA has devoted a medium-term report to renewable power sources and the agency says this is “a recognition of the dynamic and increasing role of renewable energy in the global power mix”. It forecasts that renewable electricity generation will expand by 1,840 TWh between 2011 and 2017, almost 60% above the 1 160 TWh growth registered between 2005 and 2011.

Inspecting wind turbine blades is a time-consuming part of operating a wind farm and not always exact given that many inspections are carried out from the ground. The ability to send robots to the top of these increasingly bigger structures to monitor the blades is clearly attractive and two companies believe they may have found a way to turn this into reality.

Nicole Bricq

After a difficult few months for the French wind industry, Nicole Bricq, appointed French minister for ecology, sustainable development and energy, and now minister for external commerce, signalled her support for the sector and promised she will ensure that new projects can go ahead as planned.

The wind sector took a knock of confidence in May when France’s highest administrative court the Council of State asked the European Court of Justice (ECJ) to rule whether the country’s premium purchase price for onshore wind constitutes state aid. The tariff remains in place – it could take the court up to two years to make a final decision – but the referral has cast a wave of uncertainty over the industry.

Much has been made of the European Environment Agency (EEA)’s recent report that greenhouse gas emissions increased in 2010. But what is equally as interesting is the key role that renewables including wind played in containing further emissions growth.

The EEA reported last week that EU greenhouse gas increased by 2.4 % in 2010 as a result of economic recovery in many countries after the 2009 recession and a colder winter. “This rebound effect was expected as most of Europe came out of recession,” said EEA executive director Jacqueline McGlade. “However, the increase could have been even higher without the fast expansion of renewable energy generation in the EU,” she insisted.
