Costs of coal

Costs of Coal

  • Non-renewable resource.

  • Burning coal increases carbon dioxide.

  • Environmental health (increasing sulfur, nitrogen oxide, and mercury).

  • Human health (particulate matter).

  • Unsafe mining.

  • “And we have little more than a century to develop adequate, practical, and inexpensive technologies to replace some of these sources” (Borowitz).


Benefits of coal

Benefits of Coal

  • Inexpensive and abundant.

  • Potential for development to become safer, an example being gasification.

  • Upgrading coal is more cost effective than going to an alternative source of energy.

  • Upgrading would also lower dependence on foreign oil.


Analysis of current energy use

Analysis of Current Energy Use

Solar energy

Solar Energy

  • Photovoltaic cells.

  • Inexhaustible.

  • Minimal impact on the environment.

  • Low-maintenance.

  • Does not have good transmission and storage systems.

Geothermal energy

Geothermal Energy

  • Uses heat from inside of the earth.

  • Earth must be drilled and pumped to remove heat.

  • Huge amount of energy.

Wind energy

Wind Energy

  • Renewable energy.

  • Form of solar energy.

  • Costs lowering.

  • Wind farms.

  • May negatively effect habitats and are considered ugly.

Cost benefit analysis and alternatives in the future

Cost Benefit Analysis and Alternatives in the Future

  • Theories on cost benefit analysis.

  • Change in coal infrastructure.

  • Change to alternative energies.

  • Public Influence.

  • Government Action.

  • Drivers of Change.
