Advantages of Fossil Fuels

1. Large amounts of electricity can be generated 2. Easy to transport 3. Fossil-fueled power stations can be built almost anywhere

Advantages of Nuclear energy

1. Not expensive to make 2. Does not contribute to greenhouse effect 3. Huge amounts of energy for little fuel 4. Little waste 5. reliable

Disadvantages of Fossil fuels

1. Produces Carbon Dioxide/pollution 2. Produces more Carbon Dioxide than oil or natural gas 3. Produces Sulfur which leads to acid rain 4. Mining is difficult and dangerous

Disadvantages of Nuclear energy

1. VERY VERY VERY dangerous 2. Produces radioactive waste 3. a lot of money is spent on safety
