Evaluating energy efficiency from the perspective of clean energy and carbon emission

Improving energy efficiency and optimizing structure is the key to achieving “dual carbon” goal high-quality development. This paper calculates of 30 provinces in China between 2000 2017 using DEA method. The study found that China, higher East than West South North coastal areas interior. Moreover, gap clean fuel fossil widening. Taking total power consumption as input measuring carbon emissions regional grid base line emission factor can accurately measure China’s efficiency. conclusions provide important references for promoting transformation development green economy.
