According to me, India and China are the major contributors to the global energy demand growth.
According to the reports, India and China are the fastest-growing countries in the world. In recent news, I got to know that China is developing an artificial sun that will produce enough energy to give global growth in the energy segment. On top of that, China is also developing technologies that could fulfill its energy needs.
India is also developing large solar power plants to produce electric energy for the country. India is also making windmill farms which also produce energy to provide energy to the nearest area. India is also becoming an energy hub for the world with its technologies.
So, in my opinion, these two countries are most likely to be the center of global energy growth.
