On Jim Tinjum’s #bikethewind tour last year, he often saw the installations he visited for miles in advance — turbines towering gracefully in the distance. On his recent #bikethesun tour, covering about 1,200 miles (2,000 kilometers) of the Upper Midwest, he often had to pedal around in search of his solar destinations.”Some of the sites were nestled in to the landscape pretty well,” said Tinjum, an associate professor of engineering with a specialty in renewable energy at the University of Wisconsin-Madison.
