Three years ago my wife and I signed up to purchase an array of sixteen solar panels for our rooftop. It was part of a neighborhood group-buy sponsored by the City of Milwaukee, the Midwest Renewable Energy Association, and our local neighborhood association. Along with the purchase, we became members of the MREA and learned for the first time about their annual Energy Fair. Every year, thousands of people with an interest in sustainable energy convene in northern Wisconsin for three days of workshops, industry speakers, and other activities.
