The Alberta oil sands produce about 2.5 million barrels of oil per day.The Canadian oil sands are a large area of petroleum extraction from bitumen, located primarily along the Athabasca River with its centre of activity close to Fort McMurray in Alberta, approximately 400 km northeast of the provincial capital, Edmonton. Increased global energy demand, high petroleum dependency and geopolitical conflict in key oil producing regions has driven the exploration of unconventional oil sources since the 1970s which, paired with advances in the field of petroleum engineering, has continued to make bitumen extraction economically profitable at a time of rising oil prices. Oil sands are called “unconventional” oil because the extraction process is more difficult than extracting from liquid (“conventional”) oil reserves, causing higher costs of production and increased environmental concerns. “Oil sands are a mixture of sand, water, clay and bitumen. Bitumen is oil that is too heavy or thick to flow or be pumped without being diluted or heated. Some bitumen is found within 70 metres (200 feet) of the surface, but the majority is deeper underground.”(canadasoilsands)Although the Alberta oil sands are one of the main energy suppliers for Canada, we should limit the use of them due to the growing amounts of carbon dioxide in the atmosphere.Although the Alberta oil sands are one of the main energy suppliers for Canada, we should limit the use of them due to the growing amounts of carbon dioxide in the atmosphere. Oil sands emissions will be capped at a 100 megatonne limit per year. (CBC) “OSAG co-chair Dave Collyer said oil sands output now stands around 2.5 million barrels per day, and he doesn’t believe the emissions limit would really start to have an impact until output reaches four million barrels per day.” (CBC) The oil sands sector accounts for roughly one-quarter of Alberta’s annual emissions. Oil sands facilities are currently charged a Specified Gas Emitter Regulation (SGER) levy based on each individual facility’s historical emissions, irrespective of how intense (e.g. tonnes of GHG per barrel produced) or efficient that operation has been. Oil sands operations currently emit roughly 70 Megatonnes (Mt) per year. Limiting the oil sands will reduce the greenhouse gases being released in the atmosphere.Why we should use the oil sands?Alberta’s oil reserves play an important role in the Canadian and global economy, supplying stable, reliable energy to the world. Alberta’s oil sands have been described by Time Magazine as “Canada’s greatest buried energy treasure.” But what is oil sand exactly?” This is beneficial to Canada. The oil sands dominate Canada’s export industry.
