FOSSIL FUELS
WHAT ARE FOSSIL FUELS?
• Oil• Gas• Coal
• Energy rich carbohydraat molecules
HOW ARE THEY FORMED?
• Plants and animals die.• Their remains stay behind• Over time they get covered with large amount of
stone and sand• Under the influence of pressure a chemical
reaction takes place which changes the remains in usable forms of carbohydrates• f.e. C6O6H12 -> CH4 + …..
WHERE ARE THEY MOST COMMENLY FOUND?
WHERE ARE THEY MOST COMMENLY FOUND?
WHERE ARE THEY MOST COMMENLY FOUND?
HOW DO WE GET THEM OUT OF THE GROUND?
• Coal• Large open area mines• Mineshafts
• Oil• Oil platforms• Pumpjacks
• Gas• Gas platforms• Drilling rigs
HOW DO WE DRAW ENERGY FROM THEM? (OIL)
• Oil is boiled
• Creating different layers.
• Used for machines and production process for medicines and chemical goods
HOW DO WE DRAW ENERGY FROM THEM? (COAL)
• Mainly produces heat and electricity
• When burned it produces steam • Producing electricity

HOW DO WE DRAW ENERGY FROM THEM? (GAS)
• Energy taken with gas turbines• By rotating a dynamo• Cleaner than other FF fuels
• is the best domestic heating fuel
FOSSIL FUEL USAGE
• 87.67 % of the total energy consumption in 2012 is being produced by fossil fuels
• 2006 - Fossil fuel consumption of total energy consumption per country
• • America 85.6% • Netherlands 92.5%• Belgium 74.1%• Germany 81.6 %• Sweden 33.4%• Switzerland 53.9%
FORECAST(DEPLETION)
• Proved reserves 2005 – 2007
• Coal: 905 billion metric tonnes left.• Oil: 1119 billion barrels to 1317 billion barrels left.• Gas: 175 – 181 trillion cubic metres left.
• Daily production 2006
• Coal: 16,761,260 metric tonnes.• Oil: 84,000,000 barrels.• Gas: 2960 billion cubic metres.
FORECAST(DEPLETION)
• For how long do we still have fossil fuels?
• Using the information given on the previous dia
Coal: 148 years Oil: 43 years Natural gas: 61 years
• Most optimistic guess
Coal: 417 years Oil: 43 years Natural gas: 167 years
FOSSIL FUEL USAGE (FUTURE)
• What to consider
• Population growth• Economy• Technology• Renewable energy• Depletion numbers of fossil fuels
HOW DO WE GET THE MOST OUT OF THE REMAINING QUANTITIES?
• Use more renewable energy
• New inventions
• Save energy yourself!
PRO’S OF FOSSIL FUELS
• Very large amounts of electricity can be generated in one place using coal, fairly cheaply.
• You can build fossil-fuelled power stations almost anywhere, as long as you can transport the fuel to the power station.
• The transportation of gas and oil to power stations is easy.
CON’S OF FOSSIL FUELS
• Pollution (carbon dioxide and acid rain)
• Not renewable on short terms
• Large area’s of landscape are ruined because of mining and landscape is needed to store coal near the power stations
CONCLUSION
• Right now, we can’t live without fossil fuels
• Preserve fossil fuels
• We need to change our energy production
