How to explain the "electric energy substitution" that State Grid has been proposing?

"Electric energy substitution" means replacing coal with electricity, replacing oil with electricity, and electricity comes from afar!

The core is to change the development mode of energy and electricity, and the key is to speed up the construction of UHV power grid and promote the intensive development and overall planning of large coal-fired power, large hydropower, large nuclear power and large renewable energy bases.

The essence is the problem of energy development mode and long-term accumulation, and it is the result of concentrated exposure of deep-seated structural contradictions, improving the atmospheric environment and solving the smog problem.

The methods include electric boiler, water-ground source heat pump, air source heat pump and energy storage interconnected heat pump system. To replace coal-fired, oil-fired and gas-fired heating, and to replace oil-fired vehicles with new energy electric vehicles. Peak-valley electricity price policy is used to carry out phase change cold storage/heat storage thermal balance power grid load, increase the proportion of electricity, clean energy and renewable energy, reduce rural earthen stoves and use electric stoves more. As long as electricity can be used, it will be used to replace traditional or conventional energy sources.
