The implementation of "coal to electricity" is mainly due to the following reasons:

1. Environmental protection: The exhaust gas and particulate matter generated by coal combustion are harmful to the environment and human health. Exhaust gas includes sulfur dioxide, nitrogen oxides, and particulate matter, which are one of the main sources of atmospheric pollution. By implementing the conversion of coal to electricity, the emissions of pollutants generated by coal combustion can be reduced, air quality can be improved, and the impact on the environment can be reduced.

2. Emission reduction and response to climate change: Coal combustion is one of the main sources of greenhouse gas emissions such as carbon dioxide. Greenhouse gas emissions are one of the main causes of climate change and global warming. Turning to electric heating and reducing the use of coal can help reduce greenhouse gas emissions and address climate change.

3. Energy security: As one of the traditional energy sources, coal has certain instability in supply and transportation. As one of the more diversified forms of energy, electricity can be obtained through various energy sources, such as fossil fuels and renewable energy. Implementing the conversion of coal to electricity can increase the stability and safety of energy supply, and reduce dependence on a single energy source.

4. Improving energy efficiency: As an efficient form of energy, electricity has high energy efficiency in the process of energy conversion and utilization. Compared to direct combustion of coal, the utilization efficiency of electricity is higher, which can achieve more effective energy conversion and utilization, and reduce energy consumption.

It should be noted that implementing the "coal to electricity" policy does not mean that electricity is completely harmless or has no environmental impact. The generation of electricity still needs to consider the sustainability of energy sources and environmental impacts, such as power generation methods, energy efficiency, and the use of renewable energy. Taking into account various factors comprehensively, promoting clean and low-carbon energy transformation is an important measure to achieve sustainable development.
