  • Large amounts of electricity can be produced using coal, so it is able to meet increasing energy demands.
  • The transport infrastructure to move coal around the world is well-established and reliable.
  • Coal power stations are relatively easy to build, and they can be built almost anywhere.

The disadvantages of using coal:

  • Coal produces large amounts of greenhouse gas emissions, including carbon dioxide, when burned in power stations.
