|You may never see those savings.|
But will pay plenty today.
I see it in the construction business. Houses went from 2x4 to 2x6 walls and that was okay. Then vapour barriers were added and that was sort of okay for stopping the breeze but trapped moisture and called for powered make-up air and double skins on the newest houses. Now advanced green-thinking people have 2x8 walls and I've seen triple walls that are two feet thick on a summer cottage. The end height of trusses was just mandated up a few inches and adds 5% to 10% to the cost of every roof in Canada. Houses are more expensive for many reasons but mandated spending to save a few bucks is a big factor, pleasing to elites and costing you and me.
