In a sign of the times, oil giant Shell's renewable energy division has joined the European Wind Energy Association (EWEA) as a corporate member. Shell International Renewables is the fifth largest division at Shell, according to EWEA chief executive Christophe Bourillon, and is represented at EWEA by the head of biomass and wind energy, Frank van Oorsouw. He is based at the Shell centre in London. "We are looking at investment opportunities [in wind], but it will take another couple of months before we can come out in the open," says Van Oorsouw. Shell Expo, the UK based exploration division of Shell which the renewables division is a part of, has put together a small task force to look at opportunities in wind energy, adds Van Oorsouw. Since Shell is not yet actively involved in the wind industry it only qualifies as a corporate member of EWEA in the association's third and lowest-priced category, says Bourillon. Its membership thus amounts to just £500 a year, compared with £3500 in the top category, since membership fees are based on turnover. "Until now Shell has been doing PV and biomass, but now there should be some concrete involvement from Shell in wind," says Bourillon. "They are joining EWEA to join the industry." EWEA's offices are also in London.
