An Arizona ballot proposition that would have mandated a significant jump in the use of renewable energy sources in the state by 2030 was rejected by voters by more than a 2-to-1 margin.

The growing need for renewable energy sources will inevitably become more apparent to state leaders, while and the solar energy industry or other clean energy industries will continue to make progress, says Roedel, who is director of the Fulton Schools Professional Science Master’s program in Solar Energy Engineering and Commercialization.
