I am not a sports fan, but I like what the Philadelphia Eagles are up to these days when they're not playing football: They're transforming Lincoln Financial Field into what will be the most energy-efficient stadium in the world.
They are installing 100 spiral-shaped wind turbines, 2,500 solar panels, and a cogeneration power plant that can run on biodiesel.
According to the Philadelphia Inquirer, "the three sources will fully power any game, even as the stadium lights blaze, and the sound system blasts."
"In effect, the team will be off the grid," reports the Inquirer, "although the system will remain tethered to feed unneeded juice back into the grid."
Over time, the investment will pay for itself. According to the Inquirer, "[t]he team expects to save $60 million in energy costs over the next two decades."
The renovations are expected to be completed by opening day next September.
Go Eagles!
