Background
when the coal is burning. sulfur dioxide and other pollutants will also be released, except for carbon dioxide and water.The following is some typical pollution. The following is some typical pollution. automotive exhaustindustrial emissions Industrial dustnullThe advantages of new energy:
1) rich in resources
2) renewable
3) no carbon or a little carbon content, little impact on the environment;
4) widely distributed, small-scale decentralized use;
