Is setting up windmills along the sea-coast a good idea because of the constant winds there?

Wind turbines must be placed where there are fairly constant winds. On the sea coast the winds flow out to sea during the night and morning and toward the land after ~ 10Am until after sundown.

Wind turbines can rotate 180 degrees so they can operate all of the time there is wind.

As far as Bird strikes go, Birds learn to avoid them or die. The efficiency of turbines is increasing and costs are decreasing. wind turbines are moveable.

Yes it is a good idea, better than oil drilling.

Utilities are forced buy electricity from windmills and solar.  Then all utility customers are forced to pay extra on their monthly bill because wind and solar electricity is far more expensive to produce than nuclear or natural gas.  This is exactly how Nazi and Communists do things.  The hell with that.

Functionally a good idea, practically not, Storms at sea are very violent, with high seas (waves) sometimes over one hundred feet high.

It is functional to the energy production , but will inevitably change the wheather in the surrounding area

Extracting energy from winds will of necessity change the weather patterns that are produced by those winds.  Just another example of 'green' energy that is not well thought out.

Sea windmills kill seabirds, good idea Mr. Biden.

It's a start, although wind turbines produce a lot more power for the spin.

Many people will object to the appearance of wind turbines on seacoasts and mountain ridges, where winds are constant. But in places that have them, they become unnoticeable pretty quickly. (And if conditions allow, they can be installed in the water rather than on its coast.)
