U.S. Rep. Jared Polis’s centerpiece campaign platform to have 100 percent renewable energy in Colorado by 2050 is under fire.

Actually, it’s not really a plan thought up by Polis. According to The Hill, it’s more of a blueprint for “aspiring politicos who hope to chart their own political course with promises to bring their states and eventually the entire United States to green salvation.”

Anyway, the plan was actually authored by Mark Jacobson, who has now lawyered up after serious shortcomings were exposed in his blueprint to green salvation.

Unfortunately, the research underpinning the bill and similar efforts elsewhere, has been roundly criticized, with a peer-reviewed paper finding “significant shortcomings” and “errors, inappropriate methods, and implausible assumptions” in Jacobson’s work. The paper, published in the Proceedings of the National Academy of Sciences of the United States of America, has led Jacobson to advise the 21 authors who contributed to the peer review that he has lawyered up, rather than push back on the substantive criticisms of his work.

Making matters more embarrassing for Polis, he had already introduced a bill based on the flawed work along with U.S. Sen. Bernie Sanders to fund what one critic described as “magic thinking.”

What remains to be seen is whether Polis just silently slinks away from this platform, or lawyers up like the plan’s author and dares the media to challenge it.
