Transit cost effectively to a secure decarbonized energy system

Numerous countries worldwide have committed to the decarbonization of their economies. These countries include both developed nations such as the United States, United Kingdom, and European Union member states, as well as recently developed nations like China. A commonly adopted strategy among these countries involves initiating the decar-bonization process within the power sector. This adoption is primarily motivated by two factors: first, the existence of well-established low-carbon power supply technologies, such as wind and solar PV second, the potential for extensive electrification of fossil fuel energy demand through rapidly advancing technologies, such as electric vehicles and heat pumps. Thus, decarbonizing the power sector represents the most logical starting point in the journey toward a low-carbon future.
