This isn't the same thing - you've actually calculated that you're unlikely to save in this situation. You made a sensible decision that the payback period is so long for your own uses that it runs the risk of not actually paying back/being beneficial. The "save where possible" mindset would be more like "I calculated it would be better, but my impact is less than my workplace doing X, so I won't". Everyone should be calculating payback on these investments every couple of years, because the calculus changes depending on incentives/tech/other factors (e.g. EV purchases, or massive cost of living changes)
