Janna Greir, a shepherd in Alberta, Canada, knows solar farms can sometimes be controversial. In rural areas, large arrays that take over hundreds of acres of former agricultural land. That can be a tough loss for local farmers, especially ones with links to the land going back generations. 

But Greir, a farmer herself who is also passionate about green energy and sustainability, wanted to demonstrate that land used for solar panels can still be used for agricultural purposes. So when an Edmonton-based Capital Power installed about 240 acres of solar panels on a plot about 10 minutes from Greir’s farm outside of Strathmore, she saw an opportunity to introduce solar grazing to the region.
