Stone mills were powered by water or wind to grind the grain between two large stones. Stone mills were common throughout Europe and they were excellent for grinding soft wheat varieties. The grain is poured into a hole in the upper stone, called the runner, and is distributed across the bottom stone, called the sleeper. ...

These mills have been used to grind grain, power saws, pulp wood for paper, and perform a variety of other tasks that call for mechanical energy but do not necessarily need electricity. Wind turbines, on the other hand, are often large-scale power generators that provide energy to the grid for consumption in other locations.
