Minnesota officials have set an ambitious goal for the state to be carbon-neutral by 2050. And our Getting to Green series has been digging deep into stories of the clean energy transition. What opportunities and obstacles lie on the path to reach a carbon neutral Minnesota milestone? MPR News correspondents Dan Kraker and Kirsti Marohn guest hosted a series of conversations to talk to experts and listeners about our state's energy future. As a part of that reporting, they toured the home of William and Kristin Mroz-Risse which is now fully electric and more energy efficient. Kristin works for the Minnesota Pollution Control Agency as the GreenStep Cities and tribal nations coordinator. William works in the renewable energy sector.
