Transcript of Coal Mining
- BC: 10
- AB: 9
- SK: 3
- NS: were 2 Economic Importance to Canada/Costs Importance:
- Electricity (12% from coal), heat, steel, cement
- Plentiful (6.6MT of reserves)
According to the Coal Association of Canada, "42,000 people are directly employed by the coal industry."
- Government millions of dollars in royalties each year.
- In 2011, they collected $698 million dollars in tax
- Environmental concerns
- Burning fossil fuels & open pit mining
- Coal mines are privately owned The Issues Effect on environment, people etc. Stakeholders? Companies - lose money
Employees - lose jobs
Government - doesn't collect royalties and tax revenues
Us - lose an affordable energy resource The Issue with Coal Mining in Canada Possible Solutions Maps B.C Saskatchewan Nova Scotia Coal Burning:
Adds to air pollution. Also damages environment, people, wildlife.
Land: Hard to restore
Health of Nearby Communities: Heavy metals and toxins, cancer
Safety for Underground Workers: ventilation, collapse, explode (methane gas)
- They wash coal to reduce the ash and sulfur dioxide emissions
- They also use filters to remove up to 97% of sulfur emissions
- Specific burners and re-burning to reduce even more chemical emissions To be more specific, Mountaintop removal is also an issue http://www.grinningplanet.com/embed/mountaintop-removal-mining-video/google-earth-to-mtr-mining-advocates.htm Pros and Cons to Wind Energy: Pros: Cons: Cons: Pros: - Lots of it
- Doesn't cost us money - Not renewable
- Big impact on environment
- Transportation is not cheap
- Produces methane gas
- Toxins - Clean
- Reduces: greenhouse gases, fossil fuels
- Anywhere - Not blowing 24/7
- tax dollars
- Kills animals History of Coal Mining in Canada - timeline 1693 2013 1947 1950's 1960's 1970's 1980's Grand Lake NB oil and natural gas heating popular oil was $$$ new mines, ports & railways (CP) 4 th largest exporter
Export: metallurgical + thermal Pros and Cons to Solar Energy: Pros: Cons: - Renewable resource
- Not noisy - Expensive - $100- $10,000
- Only in daylight
- Weather = bad
- Air pollution = bad Coal Mining's Contribution to Canada's Transportation Systems Railways:
- Canadian Pacific (CP) 1881
- Vancouver - Montreal
- Canadian National (CN)
- Major railways
- 30 million tones
- 80% shipped in BC Ships/Ports: - Port Metro
- West-shore Terminals Vancouver
- Neptune Terminals near
- Ridley Terminals near Prince Rupert
- Port of Thunder Bay Open Hopper: Rotary Gondola According to Canadian Wind Farms "About 2% of Canada’s total electricity demand" comes from wind generated electricity. (Surface mining) Introduction: What would happen if we stopped mining coal?
Could the industrialized world survive?
Coal supplies 40% of the world's energy needs! The Issue: When coal is burned it creates carbon dioxide
which adds to greenhouse gases causing global warming
In addition, when coal is burned, toxins such as: sulfur and mercury are released into the atmosphere According to the Government of Canada, “Ninety-seven per cent of Canada’s coal is found in the Western Provinces” Coal Mountain, 30KM south of Sparwood, BC is the largest coal mine in Canada. In 2008, they produced 2.2MT of coal Use of Coal Produced in Canada What about possible wind and solar energy? Can these clean energy sources replace coal? Conclusion Coal is an important industry in Canadian economy. Other energy sources given today's technologies just aren't affordable or reliable.
Research and development for clean coal is helping to improve the environment. Restoration to the old mining land currently being updated to higher standards. Pros:
