  11. 11. CHINA’S ENERGY SECURITY <ul><li>Energy consumption parallels that of its economic development – it has more than quadrupled since 1980. </li></ul><ul><li>Energy Secure </li></ul><ul><ul><li>China is the biggest producer of coal in the world, and relies on coal for 70% of its electricity generation. </li></ul></ul><ul><ul><li>The country also has large oil fields and controls 3% of the world’s oil reserves. </li></ul></ul><ul><ul><li>Though no longer self sufficient, can afford to import oil, predominantly from the Middle East. </li></ul></ul><ul><ul><li>Also relies on renewable energy; HEP (including the Three Gorges Dam) accounts for 16% of its energy production and therefore are plans to build HEP dams on all major rivers in China. </li></ul></ul>
  12. 12. CHINA’S ENERGY SECURITY CONTD. <ul><li>Energy Insecure </li></ul><ul><ul><li>Dependency on coal – vulnerable to global warming sanctions. </li></ul></ul><ul><ul><li>Chinese government being pressure to find alternatives to coal in order to reduce its level of pollution and contribution to climate change. </li></ul></ul><ul><ul><li>China’s largest oil fields have now peaked and some say that oil will run out within two decades. </li></ul></ul><ul><ul><li>Oil deposits in the Tarim Basin, in the west of China, are difficult and expensive to exploit, due to its remote location and difficult geology. </li></ul></ul><ul><ul><li>China’s deepwater exploration for oil may be threatened by political conflict with Vietnam and the Philippines. </li></ul></ul><ul><ul><li>HEP: natural hazards are a major threat to dams, and after the Sichuan earthquake, plans for extensive construction of dams may be reconsidered </li></ul></ul><ul><ul><li>Natural gas: very expensive and difficult to build pipelines from gas fields in Western China while liquefied gas is in short supply </li></ul></ul>

  16. 16. DISRUPTING ENERGY SUPPLIES: RUSSIA AND EUROPE <ul><li>Russia and Ukraine Gas Dispute </li></ul><ul><ul><li>In November / December 2004, Ukraine’s government changed. </li></ul></ul><ul><ul><li>This government had pro-Western policies as opposed to pro-Russian policies. </li></ul></ul><ul><ul><li>As a result, Russia quadrupled the price of its gas to Ukraine and the government of Ukraine refused to pay. </li></ul></ul><ul><ul><li>Gazprom (51% owned by Russian government) cut of the gas to Ukraine. </li></ul></ul>
  17. 17. DISRUPTING ENERGY SUPPLIES: RUSSIA AND EUROPE CONTD. <ul><li>Europe’s dependency on Russia </li></ul><ul><ul><li>Russia supplies a large proportion of Europe’s gas, and most of this is piped through Ukraine. </li></ul></ul><ul><ul><li>When Gazprom stopped supplying gas to Ukraine, the flow of gas to the rest of Europe fell by 40% in some areas </li></ul></ul><ul><ul><li>Countries that rely on Russian gas could suffer economically if gas is cut </li></ul></ul><ul><li>Europe’s energy security </li></ul><ul><ul><li>Gazprom relies on income from gas exports to Europe </li></ul></ul><ul><ul><li>Russian gas was stable even during the Cold war </li></ul></ul><ul><ul><li>New pipelines planned which bypass Ukraine and Blarus </li></ul></ul><ul><ul><li>South Caucus pipeline will bring gas from Azerbaijan to Europe via Turkey </li></ul></ul><ul><ul><li>Europe looking alternative energy sources </li></ul></ul>

  19. 19. LOOKING FOR MORE ENERGY <ul><li>Canada’s oil sands </li></ul><ul><ul><li>Oil sands are thick slurry composed of sand, water and type of oil called bitumen </li></ul></ul><ul><ul><li>Largest reserves of oil sands are in Alberta in Canada; produced a million barrels of oil per day in 2003 and plan to produce 5 million barrels a day by 2030 </li></ul></ul><ul><li>Costs of exploiting oil sands </li></ul><ul><ul><li>Expensive to extract oil </li></ul></ul><ul><ul><li>Very energy intensive and a large source of greenhouse gas emissions – conventional oil production requires much less energy </li></ul></ul><ul><ul><li>Very water intensive – 2 to 5 barrels of water to produce every barrel of oil </li></ul></ul><ul><ul><li>Environmental impacts – removal of trees, shrubs and soil </li></ul></ul>
