Consuming resources

• Natural resources (found in the natural world that we can use)
• Human resources (the skills of a popualtion in a society)
• Material or capital resources (resources that are already in the country)

Availbility

• Non-renewable resources 
  • like coal, oil or diamond
  • can not be remade, because it would take millions of years for them to form again.
• Sustainable resources
  • like wood 
  • can be deliberately renewed. They can be managed and usable not but also in the future.
• Renewable resources 
  • like solar power or wind power
  • renew themselves, and do not need to be managed

Uses of oil (crude) include:

• Car fuels
• Powering factories / power stations
• Plastic
• Cosmetics
• Power: electricity
• Medicines
• Perfume
• Paint
• Fabric

• Consumption has rapidly increased
• In 2005, world consumption was 87 million barrels per day
• In 1965, world consumption was 30 million barrels per day
• In 40 years, the world consumption rates has over tripled
• Asia consumes the most

Why has consumption increased?

• More technology
• More people
• More labor-saving devices
• GDP has increased

• encourage/subsidise home renewables eg. solar panels and windmills
• tax more polluting vehiclea heavier

• Hydrogen fuel cells
