Wind turbines at sea.
What a wind turbine can't do is to produce electricity when the wind is not
blowing. If we want that, we need to store the energy (somewhere) for later use.
Batteries might be the first you think of but consider that we need to store
energy for a number of wind turbine in the MWh class. The batteries themselves
will not last as long with this type of charge and discharge that occurs here.
We should be able to store the energy that can withstand this
