1. Non-sustainable energy:
Drilling for oil

2. Definition Renewable resources: Nonrenewable resources:
any natural resource that can be replenished naturally with the passage of time
Nonrenewable resources:
natural resource which cannot be reproduced, grown, generated
Resources that are consumed much faster than nature can create them

3. Definition*
Crude oil/petroleum - "unprocessed" oil, the stuff that comes out of the ground
Hydrocarbons – a compound of hydrogen and carbon
naturally-occurring flammable mixture of hydrocarbons found in geologic formations

4. Crude oil
Remains of animals and plants that lived millions of years ago in a marine (water) environment before the dinosaurs
  Over the years, the remains were covered by layers of mud
Heat and pressure from these layers helped the remains turn into what we today call crude oil

5. Crude oil refinery

6. Usage Kerosene Waxes Lubricants Asphalt Rubber Textile
Sport equipments
Basket balls
Hockey sticks
Top two – gasoline 19%, Diesel 10%

7. Where to drill?
Geologists examine surface rocks and terrain, with the additional help:
 satellite images
gravity meters
magnetometers
Gravity meters - they can use sensitive gravity meters to measure tiny changes in the Earth's gravitational field that could indicate flowing oil,
Magnetometers -  to measure tiny changes in the Earth's magnetic field caused by flowing oil

8. Oil sands

9. Bitumen
A layer of water and heavy oil that cover grains of sand

10. Where is oil crude oil found?

11. Alberta’s oil sands

12. Consideration before beginning
Land must be cleared and leveled
May need to build roads
Need a source of water
Waste disposal
Water - Because water is used in drilling, there must be a source of water nearby. If there is no natural source, the crew drills a water well.
Waste disposal - The crew digs a reserve pit, which is used to dispose of rock cuttings and drilling mud during the drilling process, and lines it with plastic to protect the environment. If the site is an ecologically sensitive area, such as a marsh or wilderness, then the cuttings and mud must be disposed of offsite -- trucked away instead of placed in a pit.

13. Flattening out the land

14. Alberta

15. Extracting bitumen
Too thick to pump out so bitumen must be dug out
