Can you talk about the practical value of changing coal into electricity and gas?

Turning coal into electricity has many advantages. 1. Environmental pollution is reduced, and harmful gases discharged into the atmosphere are reduced. 2. Reduce waste of resources. Coal is a non-renewable resource, so use less. 3. With the increase of safety factor, there was neutral gas when burning coal, which will not appear after the transformation. In fact, the cost after the renovation is similar, and the government has policy subsidies for heating in winter.
