Sports venues as solar farms

Sometimes commercial interests can actually be beneficial to the environment. Let’s say you own a sports stadium: how do you monetize that huge piece of real estate in the hours when there’s no events being held in it? Why not imitate AT&T Park, home of the San Francisco Giants, and [beware pop-ups]cover the building with solar panels that will create nice clean energy you can sell back to the grid. That way, everyone’s a winner. [Engadget]
