(Pierre, SD) — South Dakota is now part of a movement towards clean energy. The state is joining a plan with the company Xcel Energy, along with five other states in the upper Midwest. Xcel wants to reduce carbon emissions by 80 percent, retiring all coal plants by 2030. It will also continue use of their two carbon-free nuclear plants while adding more wind and solar energy to existing systems. North Dakota, Minnesota, Wisconsin and Michigan are also taking part with a goal to reach 100 percent carbon-free electricity in the next two to three decades.
