Technologies exist that can be built into the turbine. Although they are used in Canada, Denmark and Sweden, Hu said the U.S. wind industry has found them to be cost-prohibitive.... blades can incorporate a material that conducts electricity that can prevent icing by warming the blade. He said the cost for the power amounts to roughly 5% of the energy a turbine might typically produce.
