When the Mall of America was built, it didn't have a heating system. It only had a cooling system. The waste heat from lighting, appliances, and people is enough to keep it warm all year. Each person counts for about 75-100 watts (at a rate of 1800-2400 Calories per day).Think about the carbon footprint of living in MN in the winter. The energy needed to keep cities and homes and "malls of America" warm all the chilly winter of MN is not something that politicians want to give away money for select-few new car buyers to claim. Heating-based NG, oil and coal burned in the state must be huge every year.

Most conventional MN homes are heated by natural gas, propane, electricity, or wood. Some homes are fully solar or are superinsulated. Renewables make up MN's only in-state energy resource and are growing rapidly in capacity. Currently, most energy is imported from neighboring states or Canada. One of the main refineries is Koch-owned, and about 80% of the oil it processes is from the Alberta tar sands in Canada.
