Reducing dependency on coal, oil, and gas is a critical component of accomplishing important climate goals like the United Nations’s Sustainable Development Goals. In its Energy Strategy for 2050, the European Union declares that member countries must prepare their infrastructure for further decarbonization of their energy system in the long run, 2050. Therefore accurate energy utilization planning to achieve sustainable goals for the world is needed. The sustainable goals for decarbonization are different in various locations of the world, which lead to sustainable transition. This chapter has presented the requirement of various sectors and categories, which are involved in this world’s sustainable transition process. The penetration of renewable energies like solar, wind, and hydropower in different sectors will have a major contribution toward sustainable transition progress, at the present state utilization of renewable energies for transportation, industrial empowerment, and domestic utilization. Renewable energy resources are the future of the energy sources of the world, and these resources are implemented as under distributed energy generation mostly which is considered for microgrid and nanogrid formation. The planning of the energy strategies has a greater role in the widespread application of a smart grid which helps in the sustainable transition to reduce the emissions to the environment. All the components such as e-mobility, smart grid, renewable resources, and digitalization play an important role in decarbonization to achieve sustainable goals. © 2024 Elsevier Inc.
