Learning Objectives
• You will check your understanding of different power sources
• You should be able to recognise & undertake different ways of classifying power sources.
• In addition, you should be able to recognise advantages and disadvantages of different power sources.

Resources
• “features of the environment which are needed and used by people.”
• Natural Resources - occur in the air, water and on land.
• Human Resources - labour, skills, machinery and capital.

Non-Renewable Resources
• Are said to finite or non-sustainable as their exploitation and use will eventually lead to their exhaustion.
![Page 17: Managing Resources Lesson 1](https://reader033.fdocuments.us/reader033/viewer/2022060112/556d0988d8b42ad34f8b4ae3/html5/thumbnails/17.jpg)
Renewable resources
• A flow of nature- being continuous, they can be used over and over again.
• Sustainable- they are renewable and self generating if left to nature e.g. trees, fish
– However, if renewable resources are overused their existence may be threatened.

Reserves
• are a non-renewable resource (e.g. coal) which exists in a finite quantity in the crust of the earth
![Page 20: Managing Resources Lesson 1](https://reader033.fdocuments.us/reader033/viewer/2022060112/556d0988d8b42ad34f8b4ae3/html5/thumbnails/20.jpg)
Fossil Fuels and Minerals
• Coal, Oil and Gas are non-renewable resources created from organic matter
• They are used to produce energy and are the quickest and easiest way of generating vast amounts of energy
• 1 modern ‘fossil fuel’ power station produces the same amount of energy as:
300 wind turbines 150 km2 of solar panels 100 kms of powerful coastal wave energy

Future Reserves
• Oil 40-45 years• Natural Gas 50-65 years• Coal 200-300 years
• MEDC’s contain 25% of the world’s population BUT consume 70% of the world’s fuels!

Task
• Produce a leaflet advertising your preferred type of energy creation
• Explain why it is a renewable form of energy
• What its advantages are, but also if there are any problems
• Find an example of where and how it works
• Images may also be useful
