  1. The Problem with Burning Fuels

  2. Carbon Dioxide Sulphur Dioxide Oxides of Nitrogen SOx and NOx

  3. Global Warming

  4. Acid Rain

  5. It is possible ( but expensive ) to take most of the sulphur out of fuels before they are burned It is possible to remove most of the sulphur dioxide from the smoke after the fuel is burned

  6. We are running out of oil. What will we do when it runs out?

  7. Alternative Fuels? Hydrogen Hydrogen + Water  Water

  8. To make hydrogen we need Water Electricity Is it really a clean fuel?

  9. Ethanol – otherwise known as alcohol We can make ethanol by fermenting corn

  10. Burning ethanol still produces carbon dioxide but …. Overall we would not be adding to the amount of carbon dioxide in the atmosphere

  11. Biodiesel This is another “carbon neutral” fuel.

  12. What gas from burning fuels causes global warming? Why is global warming a problem? (2 reasons) What gas from burning dirty fuels causes acid rain? Why is acid rain a problem? How can we reduce the amount of acid rain? Fossil fuels are non-renewable. What does this mean? Why is this a big problem? Write a word equation for burning hydrogen in air Where could we get lots of hydrogen from? Where could we get lots of ethanol from? Why is ethanol a “carbon neutral” fuel? Name another carbon neutral fuel.
