Legislators want to make Minnesota the fourth state in the country to set a 100 percent clean energy plan, with the aim of having electricity providers generate all energy from renewable sources by 2050.
"Business as usual and relying on markets is not going to get the job done in time. The crisis is urgent," said the measure's sponsor, Rep. Jamie Long, D-Minneapolis.
Electric utility companies would need to meet a series of deadlines to reduce their use of fossil fuels over the next few decades under the proposal.
Dozens of people showed up at the State Capitol on Tuesday to champion or warn against the idea. Religious leaders, youth advocates and environmental organizations said it would benefit future generations and vulnerable populations who they say are disproportionately affected by climate change. They urged the state to push for change in the face of federal inaction.
But some electric companies and Republican legislators called the idea an unreliable way to power the state and said a mandate is the wrong approach. Some electric providers raised concerns about extreme weather and limits on how much energy renewable sources, like solar and wind power, can produce.
There are days when there is no wind in the Midwest or the temperature forces turbines to stop generating power, said Kenric Scheevel, with Dairyland Power Cooperative. He said companies still need to rely on fossil fuels in those circumstances.
"We still need a balanced, all-of-the-above generation portfolio," Scheevel said. "Before we take this idea for a drive onto the lake, let's make sure the ice is strong enough."
The idea was debated days after a deep cold spell strained utility companies and left some residents without heat.
