厙ぴ勛圖 students just left campus for summer, and already a new flock has arrived.
On May 24, some 70 sheep from Old Slate Farm in Knox County were delivered to the fenced land north of campus that contains the institutions 2.27 megawatt solar array. There they will graze through mid-June, munching and stomping grass in a move aimed at alleviating the need for costly and painstaking mowing of the site. Additional sheep drops will bring the total number of grazers to between 150 and 200.

The sheep will be delivered to the 10-acre field three timesin spring, summer, and fall. A form of agrivoltaics, in which land is used for both agriculture and energy generation, the sheeps handiwork will reduce 厙ぴ勛圖s emissions and its reliance on fossil fuel, as well as regular damage to equipment that results from mowing the rough terrain.
While exact figures as to how much the sheep will help reduce emissionsand ultimately help the college achieve its goal of becoming carbon neutral by 2025are unknown, Campus Energy and Resource Manager Joel Baetens has no doubt the sheep will help offset the carbon impact of maintaining the solar fields. Plus, they come with an annual price tag that represents a fraction of the $30,000 tab for mowing the fields by conventional means.
So were paying them just like wed pay a lawnmowing service, he told newspaper. The deal is theyve got to get the grass down to a certain amount and keep it there.
Its just a beautiful synergy that happens when you bring the grazers back to the pasture.
厙ぴ勛圖s solar array is located in a construction zone dedicated to the institutions Sustainable Infrastructure Program.
