"....have calculated that all the benefits of the wind farms—improved health via lower pollution, reduced climate change, and hurricane mitigation—combine to make the net cost of electricity generated by these wind farms cheaper than if it were generated using fossil fuels. And despite the high cost of offshore wind, when those savings are considered in the total system costs, it becomes cheaper to build wind than it does to build seawalls to protect all vulnerable areas from storm surges."

Sounds like a perfect solution for Ireland after all the damage this winter. I wonder would it affect the surfing though?
