  1. 1. Fossil Fuels Eno Helleng Kristiina Rõžova Teacher: Estra Tõnisson
  2. 2. What are they? <ul><li>Natural subtances </li></ul><ul><li>Energy </li></ul><ul><li>Coal, oil and gas </li></ul><ul><li>Non-renewable </li></ul>
  3. 3. Coal <ul><li>Coal provides around 28% of our energy </li></ul><ul><li>Acid rain </li></ul><ul><li>Coal is mined in over 50 countries </li></ul><ul><li>Old coal mines are often dangerous </li></ul>
  4. 4. Oil <ul><li>Oil (also called petroleum) provides 40% of our energy </li></ul><ul><li>Cheaper transport than coal </li></ul><ul><li>Oil can be anywhere (from few meters to kilometers underground) </li></ul><ul><li>Very first oil well was drilled in 1859 </li></ul>
  5. 5. Natural gas <ul><li>Natural gas provides around 20% of our energy. </li></ul><ul><li>Easy to transport </li></ul><ul><li>Little pollution </li></ul><ul><li>Drilled out of ground </li></ul><ul><li>Mainly used for heating homes </li></ul>
  6. 6. Interesting facts <ul><li>Fossil fuels supply about 90% of world’s energy </li></ul><ul><li>Humans are using fossil fuels 100,000 times faster than they are being made </li></ul><ul><li>Fossil fuels contain carbon. When burning carbon goes into air and joins with oxygen. </li></ul><ul><li>Too much CO2 can cause death </li></ul>
