Wind power is not very efficient and although it is renewable, that doesn’t mean it doesn’t have significant environmental drawbacks. From Craig Rucker at realclearenergy.com:
The reality is a lot of turbines, not much energy.
President Biden recently announced ambitious plans to install huge offshore industrial wind facilities along America’s Atlantic, Gulf of Mexico and Pacific coasts. His goal is to churn out 30 gigawatts (30,000 megawatts) of wind capacity by 2030, ensuring the U.S. “leads by example” in fighting the “climate crisis.”
Granted “30 by 2030” is clever PR. But what are the realities?
While that might sound impressive, it isn’t. It means total wind capacity for the entire Atlantic coast, under Biden’s plan, would only meet three-fourths of the peak summertime electricity needed to power New York City. Again, this assumes the blades are fully spinning 24/7. In reality, such turbines would be lucky to be operating a top capacity half the time. Even less as storms and salt spray corrode the turbines, year after year.
The reason why is there is often minimal or no wind in the Atlantic – especially on the hottest days. Ditto for the Gulf of Mexico. No wind means no electricity – right when you need it most.
Of course, too little wind isn’t the only issue. Other times, there’s too much wind – as when a hurricane roars up the coast. That’s more likely in the Gulf of Mexico. But the Great Atlantic Hurricane of 1944 had Category 4 winds in Virginia, Category 3 intensity off Cape Hatteras (NC), Long Island and Rhode Island, and Category 2 when it reached Maine. It sank four U.S. Navy and Coast Guard ships.
When storms or hurricanes hit, turbines can be destroyed. Repairing or replacing hundreds of offshore turbines could take years.
