Under Obama-Biden, “$15B went to energy efficiency, which turned out to be a massive waste of money. 2x as much money was spent weatherizing homes as was saved. The episode disproved the myth that efficiency investments always “pay for themselves.” https://www.forbes.com/sites/michaelshellenberger/2019/02/08/the-only-green-new-deals-that-have-ever-worked-were-done-with-nuclear-not-renewables/
“Determined to learn nothing from history, Green New Dealers are now proposing to spend taxpayer dollars weatherizing every building in America.”
FWIW, this is not a left-right issue. Even @MotherJones reports, “the upfront cost of efficiency upgrades came to about $5,000 per house, on average. But their central estimate of the benefits only amounted to about $2,400 per household.” https://www.motherjones.com/kevin-drum/2015/06/home-weatherization-not-good-deal-we-thought/
Weatherization “was not a cheap way to reduce emissions. Although energy use (and hence CO2) did go down, it came at a cost of about $329 per ton. That’s much higher than the $38-per-ton value that the US federal government uses to evaluate cost-effective climate policies.”
