This week’s bitter cold had the potential to be deadly. But thanks to reliable forms of energy like coal, natural gas and nuclear power, it wasn’t.
Lawmakers considering doubling Minnesota’s renewable energy mandate to 50 percent by 2030 should use this week’s weather as a moment to reconsider their plans to lean so heavily on wind and solar.
Wednesday - Morning - Temperature - Twin - Cities
On Wednesday, when the morning temperature in the Twin Cities was negative 24 degrees, wind energy provided just 4 percent of the electricity and utilized just 24 percent of its installed capacity in a region monitored by the Midcontinent Independent Systems Operator (MISO), a not-for-profit organization that ensures reliable, least-cost delivery of electricity across all or parts of 15 U.S. states, including Minnesota.
Meanwhile, coal-fired power plants provided 45 percent of MISO’s power and nuclear provided 13 percent — most of this from Minnesota’s Prairie Island and Monticello nuclear plants (which we should keep open, by the way). Natural gas provided 26 percent of our electricity use at that time, and the remainder was imported from Canada and other U.S. states.
Natural - Gas - Homes - Percent - Minnesotans
Natural gas also heated the homes of approximately 66 percent of Minnesotans this week, by far the most for any home heating fuel, but there wasn’t enough gas to combat the frigid temperatures.
Because of the extreme cold, Xcel Energy urged its natural gas customers in Becker, Big Lake, Chisago City, Lindstrom, Princeton and Isanti to reduce the settings on their thermostats, first down to 60 degrees, then to 63, through Thursday morning to conserve enough natural gas to prevent a widespread shortage as temperatures remained 14 below zero. Some Xcel customers in the Princeton area lost gas service, and Xcel reserved rooms for them in nearby hotels.

Enacting a 50 percent renewable energy mandate will not replace coal-fired power plants with wind and solar. It will...
