Simply put, energy efficiency means using less energy to get the same job done - and in the process, cutting energy bills and reducing pollution. Declines in energy intensity are a proxy for efficiency improvements, provided a) energy intensity is represented at an appropriate level of disaggregation to provide meaningful interpretation, and b) other explanatory and behavioral factors are isolated and accounted for.

51 Plug-in hybrids also have increased battery capacity, which makes it possible to drive for limited distances without burning any gasoline; in this case, energy efficient roof tax credit 2022 (Suggested Resource site) is dictated by whatever process (such as coal-burning, hydroelectric, or renewable source) created the power.
