This system probably doesn't apply to desert areas where grass won't
grow anyway, without constant watering, but in more green countryside,
Grazing sheep are a practical means of controlling weeds and grasses
that otherwise would block the sun from ground-level solar arrays. The
practice, begun in Europe, may well become a world standard, and has
already spread to America.

Unfortunately this applies to other things as well. In general, the
sunny parts of the world are poor, third world countries with little
money to invest in projects that they sorely need.
As an idea, the Gates foundation which is currently concentrating on
World Health Care, might move on to providing every village with a
solar power energy system.
