When Is Energy Efficiency Worth the Investment?
Should you buy LED bulbs? What about replacing an old vehicle with a more fuel-efficient vehicle? When exactly is an energy efficient upgrade worth the investment? While part of these questions has environmental and safety considerations - making the answer a definite “it depends” - the financial aspects are a little more straight-forward. Essentially the answer is “yes” if the item - LED bulbs, a car, or what have you - pays for itself in a certain time frame.
