As much as Florida needs more clean energy alternatives, giant windmills don't belong on St. Lucie County beaches that were bought with public money to preserve. Florida Power & Light Co., whose representatives are lobbying county commissioners, wants to put five wind turbines on the company's property near the utility's nuclear plant on Hutchinson Island. ...Commissioner Doug Coward supports clean energy, but he correctly questions the legality of using public land for private profit. He also worries that the windmills could "change the character of the landscape" and prevent people from enjoying the rare South Florida experience of less-developed beaches.
