Wildwood - The off shore Wind Turbine projects are using sonar for ocean floor mapping .The Federal government has determined that sonar causes problems for whales as they migrate and feed. There are now in the last 3 months 22 dead whales from North Carolina to Maine this is not normal at all ,now we are finding dead dolphins too. Sonar interferes with the whales ability to navigate that is why they swim into ships and why they beach themselves. Stop the green energy madness it is not green ,it is no where near cost effective and it is not safe or pleasing to look at. Natural gas is way better.
