In fact, in 2019, it was estimated that just under 20% of electricity generated at utility-scale electricity generation facilities in the United States was from renewable energy sources.[1]

Hydronics systems? Football? While you may not hear those terms in the same breath every day, there’s actually a mind-blowing amount of design and engineering that help keep football field surfaces playable through the cold winter months.
