Oh, maybe he then says to hang your clothes out for free? Ask your HOA about that, assuming you don't live on the thrid floor of a cheap apartment building, where even if you cold hang them out on the roof, they would be stolen or vandalized before they were dry.
OTOH, how many cash strapped people are going to spend ("invest" in Lib-speak) money they don't have to replace an "inefficient" 3-5 year old fridge or freezer that is working perfectly well...for a 'pay back' that takes longer than the expected life span of the appliance?
Yep; changing light bulbs and keeping your tire pressure correct is going to solve all our energy problems.
I'm more concerned about keeping my "in basket" full of productive work. Being an employee at my company doesn't mean squat unless you have performed the necessary marketing and contracting to turn your labor into cash flow. If you're not generating cash flow to cover your salary, the company is quite happy to issue a layoff notice. It's a fine meritocracy with zero job security.
