Electric energy substitution is not only the only way to improve environmental quality

but also a necessary means to achieve the goal of carbon neutralization. It is of great significance to promote the energy consumption revolution

implement the national energy strategy and promote the clean development of energy. Starting from the comprehensive benefits of implementing electric energy substitution

the comprehensive benefit evaluation model of electric energy substitution project is established based on the grey correlation method. From the perspective of users

it finds the most suitable implementation way of electric energy substitution in Henan province

which provides theoretical support for the development of electric energy substitution in Henan province.
