Last year, the city began buying renewable energy credits in five solar installations in southwestern Wisconsin, which will help the city meet its 100 percent renewable energy goals and support economic development in that part of the state, Hoffman said.

The city is also installing solar panels on buildings and ensuring new buildings are as energy efficient as possible, she said. The city’s newest Fire Station on the Southeast Side, for example, includes geothermal heating and cooling, and solar panels.

In 2017, Madison became the first city in the state and 25th in North America to set a goal of 100 percent renewable energy and zero net carbon emissions. Six cities have already hit their targets. The council also paid HGA and Navigant $250,000 to develop strategies with various timelines to achieve the goal. In January, the Sustainable Madison Committee endorsed the report’s recommendation to achieve the city’s goals by 2030.

In early February, Mayor Paul Soglin and 10 City Council members offered a resolution to accept the recommendations and timeline. The resolution has been approved by five city committees leading to the council’s review on Tuesday.
