PROBLEMS OF USING FOSSIL FUELS? 24/05/2007
There are two main
problems of using fossil
fuels as energy sources:
They are finite, so will eventually run out.
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 left
These 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!
MEDC population MEDC fuel usage 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!!

ACTIVITY
Fill 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?
