“In the power industry, improving energy efficiency, increasing the proportion of zero carbon energy, and CCUS technology are key to achieving carbon reduction. From 2000 to 2011, the greatest contribution was made to the improvement of energy efficiency; Afterwards, the increase in the proportion of zero carbon energy will be even more crucial. CCUS technology has high cost and energy consumption, while fuel source capture technology can reduce energy consumption and improve efficiency by 5 to 8 percentage points.”
