Projects in six Minnesota cities are on display this week as more than a dozen German climate and energy leaders visit the state. Their visit is part of multiyear collaborations between Minnesota cities and their German counterparts to develop responses to climate change — from expanding solar energy to making buildings more energy efficient.
