Black coal- a sustainable fuel?

摘要

Coal is under siege. Despite the facts that coal is currently essential to the maintenance of high living standards and there is not present cost-effective substitute for this energy source, it has a poor local and international image. The continued use of coal is increasingly being called into question because of its perceived environmental consequences of its production and use and the social desire for change towards less greenhouse gas (GHG) intensive fuel sources. Coal has a major challenge to show how continued use of this energy resource can fit into a broad sustainability context.
