Unfounded claims about offshore wind threatening whales have surfaced as a flashpoint in the fight over the future of renewable energy.

In recent months, conservatives including former President Donald Trump have claimed construction of offshore wind turbines is killing the giant animals.

Scientists say there is no credible evidence linking offshore wind farms to whale deaths. But that hasn’t stopped conservative groups and ad hoc “not in my back yard”-style anti-development groups from making the connection.

The Associated Press sorts fact from fiction when it comes to whales and wind power as the rare North Atlantic right whale’s migration season gets underway.
