Reuters writes that solar farm workers recently "employed" sheep to take care of the grass that they otherwise had to maintain at a short height in order to prevent it from interfering with the solar-harnessing panels.

Thus, at the Rogane solar farm, over 100 sheep and some goats feed themselves, while also doing the work of the people who maintain the photovoltaic panels clean of any grass.

The shepherd who owns the animals, Rexhep Rrudhani, said that "the workers realised that mowing the fields was very hard, they asked me whether I could bring my sheep. The sheep eat all kind of grass here, good or bad grass, and they clean everything. We are all benefiting."

With the fifth largest coal deposit in the world, Kosovo has around 12-14 billion tons worth-of lignite and so 90% of the country's electricity is produced using coal power, while 10% is provided by renewables. Still, country officials want to completely stop using coal power plants by mid-century.

Arber Maliqi, manager of the solar plant who retired gas-powered lawn mowers, says that "producing power from the sun and cutting grass with sheep means things here go green twice."
