Experts are eyeing a promising solution to reduce planet-warming emissions: your neighborhood big-box stores and shopping malls.
The rooftops and parking lot space available at retail giants like Walmart, Target and Costco is massive. And these largely empty spaces are being touted as untapped potential for solar power that could help the US reduce its dependency on foreign energy, slash planet-warming emissions and save companies millions of dollars in the process.
At the IKEA store in Baltimore, installing solar panels on the roof and over the store's parking lot cut the amount of energy it needed to purchase by 84%, slashing its costs by 57% from September to December of 2020, according to the company. (The panels also provide some beneficial shade to keep customers' cars cool on hot, sunny days.)

Federal Reserve Chair Jerome Powell has told multiple associates and allies that there’s no chance he will bow to President Donald Trump’s calls for him to resign, vowing to withstand several more months of the president’s unprecedented, multi-pronged assault over Powell’s refusal to lower interest rates.
