Van trudged uphill in cold and darkness, under starlight, with his eyes gone big as an owl’s. It was a very steep climb. For all his hard work in the gym, the hike had Van huffing, wheezing, and rubbing his thighs. When he plodded his way over a crest, Van could see, lit up like toy ballerinas, a distant nest of gently whirring rotors. Wind power, renewable energy. Out here, those pretty dancing windmills wouldn’t smudge their perfect skies with smoke.
