Not a win because it's not vegan? Most people don't share your beliefs.
Most people are happy to use the animals we have spent thousands of years making useful
I see this as a win/win/win - the sheep farmer gets rent for the land the panels are on, the weeds are kept down by the sheep, we get clean electricity, we get wool
Ed. "Animal races" the word is species, races is for the variation in humans, or in fantasy it's the humanoid species
I suppose it would be reasonable to talk about races of sheep to talk about all the different types of sheep
