PROBLEMS OF USING FOSSIL FUELS?
24/05/2007
There are two main problems of using fossil fuels as energy sources:1.They are finite, so will
eventually run out.2.The burning of them to
create energy produces lots of polluting gases.
Copy this speech bubble into your books:
How much longer can we depend on fossil fuels?
• Coal, Oil and Gas are created from organic matter, they are fossil fuels. These DO have a life expectancy, they are non-renewable, so will run out.
• Oil: 40-45 years left• Natural Gas: 50-65 years left
• Coal: 200-300 years leftThese are the approximate number of years left for each of these energy resources
•Oil: 42 years left
•Natural Gas: 60 years left
•Coal: 250 years left
Use this data to create a bar graph showing the number of years left for each of our non-renewable energy resources.
Who consumes the most fossil fuels?
• Rich MEDCs.• 70% of fossil fuels.
• In particular?• USA
• Who uses least?• LEDCs
• Especially African.
Fossil fuel energy
MEDC’s contain 25% of the world’s population BUT consume 70% of the
world’s fuels!

Is this fair?
• Burning fossil fuels has increased pollution in the atmosphere.
• This can lead to many health problems for people, animals and plants.
• The carbon stored in fossil fuels is released as carbon dioxide when they are
burnt – this changes the green house effect and can cause global warming.
OTHER PROBLEMS!!
ACTIVITYFill in the speech bubble explaining the
following:• 1. What are the fossil fuels?
• 2. How long before they run out?• 3. Who consumes the most fossil fuels and
why?• 4. What are the problem with using fossil
fuels?Extension:You could also suggest some ways to solve the situation?
