Just found out my 'energy efficient' windows are basically a scam from 2015

I was reading some old building science stuff from Energy.gov last night and found out most windows sold before 2020 with a U-factor above 0.30 lose more heat than they save in my climate zone here in Minnesota. Those double pane units I put in 7 years ago? They're rated 0.48. My heating bills have been way higher than my neighbor's who has the same size house but with newer triple pane windows. Anyone else check their window ratings after a few years and feel ripped off?

My buddy Mike in Wisconsin just found out his 2016 windows are 0.45 U-factor and pays $200 more in heating than his neighbor.

Stuck some cheap cellular blinds on my old single panes and cut my bill by about 20 bucks a month.
