The world needs more sheep, says Janna Greir of Whispering Cedars Ranch, which is located just east of Strathmore, Alberta. That’s in part because it turns out that sheep are perfectly suited to keep the grass trimmed at solar farms like Capital Power’s 41 megawatt facility located on 320 acres leased from the Town of Strathmore.

“Cows are curious,” she says. “They get itchy. They like to rub on things. Goats like to climb and jump on things. They like to chew the wires. But sheep like to graze in and around the panels and they don’t damage them at all.” And sheep eat pretty much any weed and trampling whatever they don’t eat, reducing fire risk and providing sustainable land management.
