According to the data released by the British Energy and Climate Change Department (DECC) on the 29th, due to the maintenance of oil and natural gas production in the North Sea oilfield, the UK energy production fell by 13.5% in 2011, resulting in an increase in dependence on energy imports to 36.5%. The highest level since the year. Data show that the UK's oil production in 2011 fell more than 17%, the lowest level since 1970. Last year, the average daily oil production in the UK was 1.04 million barrels, and the total output was 52 million tons, equivalent to 381 million barrels. The department expects the British oil production will continue to decline. In addition, natural gas production in the UK fell by 21%, with total imports exceeding the total output for the first time in 45 years, of which imports of liquefied gas accounted for 47% of total imports. Natural gas exports rose 4% year-on-year, the highest level in history. In addition, primary energy consumption fell by 7%. As a result of the increase in renewable energy and nuclear power production, the proportion of low-carbon power production increased from 23% in 2010 to 28.5%. In 2011, the proportion of nuclear power in the UK increased by 3% to 19%, and the proportion of renewable energy increased by 2.5% to 9%, which is the highest level in history. Among them, hydropower increased by 58% and wind power increased by 54%. The two generating capacity increased by 55% year-on-year. Coal production fell by 0.5% year-on-year, and coal imports increased by 23%. Demand for coal for power generation increased by 0.5% and coal inventories decreased by 4%. The United Kingdom is the largest oil producer in the EU member states. However, since the early 2000s, the UK has become a net importer of oil and natural gas from 2004 and 2005 respectively, due to the gradual decline in oil and gas production. Relevant data show that in 2010, Britain produced 1.4 million barrels of oil per day, and daily oil consumption was 1.6 million barrels. However, in the past 10 years, oil consumption has remained basically stable.
