The growing adoption of solar power has become one of the major changes happening in the United States’ utility industry.
For many years, utilities have offered incentive programs to help customers install solar power, and worked with regulators and legislators to draw up rates that account for customers who have solar capacity.
This year, one U.S. state on this list became the first ever to generate more than 5 percent of its electricity from solar power.
Some states on this list are hotbeds for solar power research, whereas others have hosted pilot projects or ambitious government-funded facilities.
