The sheep return to the stable after grazing at the "Buon Pastore" dairy in Sant'alberto, Ravenna, Italy. The dairy and sheep farm work in synergy with the "Solar Farm" energy park, a 35 MW photovoltaic field capable of producing approximately 47,000 MWh of electricity, or the equivalent consumption of 18,000 families. Sheep graze among the solar panels, helping to maintain agricultural areas and turf.
