Via the New York Times:
Companies including Motorola Mobility, Lego, Deutsche Bank and Bloomberg L.P. signed up to use a new trademark, WindMade , to show that at least 25 percent of their electricity was generated by wind power. The brand is sponsored by Vestas, a wind turbine manufacturer. The company hopes to develop a widely recognized industry trademark akin to the Fair Trade and Organic labels.
WindMade has been incorporated in Belgium as a non-profit and are developing standards for their WindMade trademark. More information can be found here.
