Career capstones don't get much sweeter than the one Michael Noble of the advocacy group Fresh Energy has experienced in the last few weeks.
For more than 30 years, Noble's professional mission has been to tell this state's policymakers that climate change is real, it's human-made, and it will be catastrophic unless humankind does two things as quickly as possible:
Get all of the carbon out of the electricity supply, then electrify everything we can.
Noble had a few good years — 1994, 2007, 2013 — in which short-lived majorities of this state's elected officials paid him heed. But there were a lot of other years of doubt, disinterest, disinformation and partisan stalemate. When he decided sometime last year that he would step down in mid-2023 as Fresh Energy's executive director, Noble had no assurance that a climate-change breakthrough was at hand at the Legislature.
As I've observed even when my topic isn't global warming: Typically, government change is glacially slow. But sometimes, abruptly, an ice sheet collapses and falls into the sea.
That metaphor doesn't seem too strong for the big-deal energy bill Gov. Tim Walz signed into law last week. It requires that by 2040, Minnesota's utilities must generate 100% of the electricity they sell from carbon-free sources — that is wind, solar, hydro, nuclear and maybe some geothermal.
