The Cost of Implementing Energy Efficiency Measures

Topics: energy energy efficiency

As to whether energy-efficient measures are more costly, Wu remarks that the IAC tries to identify opportunities that are relatively easy and inexpensive to implement so that “the recommendations normally have a payback period of one year. There are so many things that are not costly. Lighting is one example. It doesn’t cost much to replace regular light bulbs with energy-efficient ones, but the savings are almost immediate because the payback period is only about one year. So after this initial investment it’s all pure savings.” While energy-efficient measures are easy to set up, “in some cases, it does involve a more substantial amount of initial investment.” Even in those cases, Wu says, his group still tries to identify opportunities with a payback period of less than three years.
