Solar for Agriculture
Of all the many uses of solar energy, agriculture is one of the most practical. Few can forget — and indeed we still often see — the use of windmills to provide free energy for pumping water.
Don't forget that wind is really a form of solar energy.
If we take a close look at the sheer economic practicality of using solar energy at out of the way locations, then the usefulness of things like solar electric fences and solar energy for water pumps becomes readily apparent.
