Climate Change

There are a lot of reasons to be concerned for the planet’s future. One bright spot in the fight against climate change is the rise in solar power use in the United States.

Solar power is more affordable than ever before. The cost of the average solar panel has dropped by 70% since 2014 and the country’s total solar capacity has risen from 0.34 gigawatts to an impressive 97.2 gigawatts since 2008. Today, more than 3% of the electricity generated in the U.S. comes from solar panels.

The best way to expand on solar power growth is by finding new surfaces to place panels. One of the most underutilized are the roofs of America’s big-box retail stores. According to a report by Environment America Research & Policy Center and Frontier Group, the average Walmart has 180,000 square feet of rooftop, which is about the size of three football fields.

Just one Walmart rooftop could generate enough solar energy to power 200 homes.
