Other critics such as Maria McCaffery, chief executive of RenewableUK, a trade body that represents more than 600 wind and marine energy firms, says the Renewable Energy Foundation's true purpose is diametrically opposed to the interests of the wind energy industry. "It is an anti-wind lobbying organisation," she told BusinessGreen. "I'd like to know where the renewable energy part of their remit is. They don't foster or promote or develop, they just try to undermine the case for wind energy all the time."[6]
