Behavioural changes in the NZE Scenario are active and ongoing changes in energy use by consumers, typically in everyday life, which tackle excessive or wasteful energy consumption. These behavioural changes also address equity issues, shrinking the wide gulf between the disproportionately high per-capita energy use in wealthy countries
In the face of global environmental problems, China has advanced a "dual-carbon" target, and the proportion of non-fossil energy consumption will be more than 25 % in 2030 and more than 80 % in 2060. Considering this goal as the starting point, this study applies the system dynamics method and combines different types of sectors and energy
We then show that the consumption efficiency factor (CEF), defined as the ratio of the maximum data rate achieved to the total power consumed, is a novel and powerful measure of power efficiency which shows that less energy per bit is expended as the cell size shrinks and carrier frequency and channel bandwidth increase.

Efficient energy use, or energy efficiency, is the process of reducing the amount of energy required to provide products and services. There are many technologies and methods available that are more energy efficient than conventional systems. For example, insulating a building allows it to use less heating and cooling energy while still maintaining a comfortable temperature. A
Renewable energy consumption efficiency fluctuated relatively low throughout the next five years, from 2016 to 2020. The APEC countries focused on economic development, such as in 2012, 2017, and 2018, while disregarding renewable energy consumption and GHG emissions.
Without progress on energy efficiency, this would have been almost three times higher. 3. Energy efficiency policies have strengthened globally in the past year. Countries representing over 70% of the world''s energy consumption have introduced new or strengthened efficiency policies since the start of the global energy crisis. 4.
Since energy consumption became an important contributor to climate change owing to carbon emissions, energy-saving behavior and expenditure at the household level have been attracting scholars
