Developing oil and natural gas in Alaska
Natural resources are?
Naturally occurring substances that are considered valuable
Natural resources include…
Renewable and non-renewable resources
Renewable Resources
Living resources
Restock and renew themselves
Non-renewable Resources
Exists in fixed amounts
Some can be renewable but take a long time
Coal: Description, Advantages, Disadvantages
Extracted from the ground by mining
We have lots of it, good resource
Causes acid rain, smog, pollution
Oil: Description, Advantages, Disadvantages
Found on lower layers of earths crust trapped by holes
Runs modern industry, good form of transportation
Drilled, expensive
Natural Gas: Description, Advantages, Disadvantages
Found under cap rocks, extracted by pipes
Inexpensive, cleaner than oil and coal
Hard to find, evaporated easily
Hydroelectricity: Description, Advantages, Disadvantages
Made when water runs down a slope and runs a turbine
No pollution, inexpensive, powers many conveniences
Needs lots of water, creates other environmental problems (blocks dams, spawning grounds)
Nuclear Power: Description, Advantages, Disadvantages
Found in power plants
No air pollution, abundant, cheap
Health risks, radioactive
What is energy?
Usable power (heat or electricity) Resources for producing power
Alternative energies uses?
Sun Wind Garbage Alcohol Air Tides
Pros and Cons: Solar Power
Reliable,consistent,efficient Sun doesn't shine all the time, needs lots of collectors, not uniformly delivered across Canada Comes from sun Passive active
Pros and Cons: Wind Power
Inexpensive, on local scale
Doesn’t blow all the time, requires turbines
Uses wind
Pros and Cons: Geothermal Power
Large amount of geothermal power trapped in the earth, renewable (green)
Expensive, require extreme care
Uses heat from underground
Power for 350,000 people
Pros and Cons: Biogas Power
Renewable, efficient, non-polluting
Difficult to enhance, not feasible
Made from garbage
Pros and Cons: Ethanol Power
Biodegradable, renewable
Corrosive, contaminates water
Made from alcohol
Gasoline contains 10% ethanol
Pros and Cons: Tidal Power
Reliable, consistent
Expensive, few suitable sites
Uses tides
How governments can conserve energy?
Develop laws

Clearcutting boreal forests
Dirty Oil
Tar sands produce lots waste (dirty oil)
3 barrels of water to 1 barrel of oil
Bitumen
Heavy, vicious crude oil that doesn’t flow naturally
Expensive
Labour intensive
Tailing Ponds
Waste water that holds contaminated waste from extracting bitumen
PAH’s
A chemical released in the extraction of bitumen that’s causes cancer and deformities
Method of mining oil sands
Surface mining
