HOW TO ACHIEVE ENERGY SOVEREIGNTY IN HIGHLAND PARK
Highland Park could be 100% powered by local clean energy resources through a combination of rooftop solar (30%), distributed solar (33%), community solar (6%), and energy efficiency (25%), alongside a Community Water and Energy Resource Center. An analysis suggests that installing nearly 44 MW of solar in Highland Park would save approximately $23 million. Achieving this requires the State of Michigan to eliminate solar restrictions and improve compensation, while the City of Highland Park must enact solar ordinances and develop local energy businesses.
