Coal has a huge environmental impact because of;

• The threat to human health due to air pollutants released when coal burns.

• The release of carbon, which contributes to global climate change.

• The fact that it is the most abundant fossil fuel.

• Its high cost, mostly to cover the transportation of coal to electric power plants.

• The use of new technology that makes coal safer and cleaner to remove from the earth and to transport to homes and industry.

Which of the following is a true statement about nuclear energy?

• It is created through a fission chain reaction in which neutrons split, releasing high amounts of heat.

• It is formed through nuclear fusion reactions, which create energy currents.

• It is formed from the breakdown of uranium into high- pressure steam.

• It is created from the oxidation reaction of the water.

• It requires the use of other fossil fuels to super heat the plutonium fuel and separate out the necessary neutrons for the reactions.
