A new campaign is being launched in Virginia to encourage the development of offshore winds. The campaign calls itself “VA4Wind” and it’s set for launch today in Richmond. Its organizers include the Sierra Club and the Green Jobs Alliance. The waters off Virginia’s coast are viewed as prime for large-scale wind power. Gov. Bob McDonnell has included offshore winds in his bid to make Virginia an energy power, but critics have questioned his emphasis on offshore oil and gas exploration. Dominion Virginia Power is studying the possibility of an offshore electric transmission line to support wind farm development.
