1. From a long-term perspective, the mainstream green energy in the future can only be nuclear fusion power generation; from a realistic perspective, the mainstream green energy that can be expected in the future is a combination of wind power + photovoltaics + supercapacitor energy storage.
2. From the perspective of grid stability, wind power and solar power mainly rely on the "West-to-East Power Transmission" model. This extreme super power transmission is very risky, and coal power is required to disperse and balance the power supply. Coal-fired power will remain indispensable in the short term.
3. In order to solve the imbalance problem of wind power and solar power generation, pumped hydropower storage and battery energy storage have risen to strategic heights. However, only supercapacitor energy storage can take on major responsibilities, and there are no insurmountable obstacles to the development of supercapacitors. .
