The cost of wind energy is examined in great detail in a report released at EWEC 2009 by the European Wind Energy Association (EWEA). The Economics of Wind Energy is a 156-page report by Søren Krohn and Poul Erik Morthorst from Denmark's Risø Laboratory and includes sections based on the work of the late Shimon Awerbuch of the UK's Science and Technology Policy Research Unit. In comparing the cost of wind energy to other forms of electricity generation, the report finds that wind power's effect in reducing a country's exposure to fuel price volatility adds an economic benefit that justifies a larger share of wind energy even if it were more expensive to generate than other sources. "Compared to other energy investments, wind creates more certainty. The fuel is free, so we are not dependent on fluctuating fuel and energy prices," commented EWEA president Arthouros Zervos.
