节能增效（energy efficiency）的定义是？Energy efficiency is defined as:
A: 某项策略与基准线比较降低10%或以上的资源使用 Any strategy that reduces resource use 10% or more from a baseline comparison
B: 某项策略与基准线比较降低20%的资源使用 Any strategy that reduces resource use 20% from a baseline comparison
C: 与传统相比，某项技术的使用要求更少的能源但却能起到相同的作用 The use of technology that requires less energy to perform the same function as a conventio

C: A compact fluorescent light bulb that uses less energy than an incandescent bulb to produce the same amount of light is an example of energy efficiency. The decision to replace an incandescent light bulb with a compact fluorescent is an example of energy conservation.

A:No specific percentages define if a product is more energy efficient than another.
B:No specific percentages define if a product is more energy efficient than another.
D:Newer building products are not necessarily more energy efficient. Doors are a good example. A door from 100 years ago was probably solid wood. A new door might be a wood frame with steel veneer and a Styrofoam core. The old door may have greater insulating properties.
