IN JACK’S SOLAR Garden in Boulder County, Colorado, owner Byron Kominek has covered 4 of his 24 acres with solar panels. The farm is growing a huge array of crops underneath them—carrots, kale, tomatoes, garlic, beets, radishes, lettuce, and more. It’s also been generating enough electricity to power 300 homes. “We decided to go about this in terms of needing to figure out how to make more money for land that we thought should be doing more,” Kominek says.
