We are mainly interested in electricity production, but before electricity was invented, windmills were used to produce mechanical energy. Often grinding grain to flour, also pumping water. This was very widespread in the Netherlands.
That's what all electrical appliances do - convert electricity into other forms of energy.That's what all electrical appliances do - convert electricity into other forms of energy.That's what all electrical appliances do - convert electricity into other forms of energy.That's what all electrical appliances do - convert electricity into other forms of energy.
Virtually all forms and types of energy are useful in some way or another.
Thermal energy is the most difficult to convert into other forms of energy.

A wind machine called windmills is powered by the energy of the wind. It is designed to convert the energy of the wind into more useful forms using rotating blades.
Windmills transform the kinetic energy of the moving air mass into other energy forms.
What makes electricity useful is that it is relatively easy to (a) transfer it over large distances, and (b) convert back and forth with other forms of energy.
Least what? Anyway, heat energy is in a way the least useful form of energy, because you can normally convert any other energy to heat energy, but if you have heat energy, you can no longer convert all of it back to other forms of energy.
It means to convert the energy to a form that is useful for humans - for making machines work, for example. Or simply, convert to a form of energy that is easily converted to other forms of energy, for example, AC electricity, at an appropriate voltage.
With steam engines, steam was used for energy. Windmills also made it possible to use wind to create energy.
