This is an average Walmart. It has 180,000 square feet of rooftop. About the size of three football fields.
That amount of rooftop space could support enough solar energy to power nearly 200 homes.
And there are lots of superstores. Our smallest state, Rhode Island, has 279.
Iowa has more than 1,000 superstores.
California has more than 10,000 superstores.
There are over 100,000 superstores in the U.S., with almost 7.2 billion square feet of rooftop. That’s the size of El Paso, Texas.
Putting solar power on all superstores could power almost 8 million homes. That’s the equivalent of powering 35 cities the size of El Paso, Texas.
It would also cut annual greenhouse gas emissions equivalent to taking more than 11.3 million gas-powered cars off the road.
