All current projections for wind energy's growth will likely turn out to be too low, the Worldwatch Institute's Christopher Flavin told Global Windpower 2004 delegates. "We're going to go through some kind of a looking glass where things are going to become more dynamic, change more rapidly and we are going to really see not only wind power, but a range of new non-fossil fuel technologies take off." The sheer market scale of the renewables business, which the institute pegs at just over $20 billion last year, will be one factor in that growth pattern. The lobbying strength that kind of money attracts, combined with technological advances, environmental imperatives, unsustainable fossil fuel supplies and a "flowering of a whole range of policy experiments around the world" will kick the sector into overdrive, he said. "There are going to be disappointments, there are going to be failures, there are going to be policies that don't succeed as well as we like, there are going to be political difficulties," he said. "But I think we are at a tipping point and I think the upside surprises are now going to overwhelm the downside surprises."
