10、the nations of non-OECD Asia and the Middle East.World Liquid Fuels Production,2005-2030 China and India account for much of the growth in liquids demand,and together they account for of the regional increment in liquids use.Middle-east:1 High birth rate 2 Subsidy 3 High income per capitaOil prices
11、In the long term,four factors determine the price of oil:1.growth in world liquids demand,2.high production costs for accessible non-OPEC conventional liquids resources,3.OPEC investment and production behavior,4.and the costand availability of unconventional liquids supply.World Liquids Production
12、World liquids production increases by 28 million barrels per day from 2005 to 2030 to meet projected growth in demand.About 47 percent of the total world increase in liquids supplies is expected to come from OPEC member countries.Thus,in 2030,OPEC production is projected to total 49 million barrels
13、per day and non-OPEC production 63 million barrels per day.Caspian area(Kazakhstan)and South America(Brazil)NON-OPEC OPECs total liquids production increases at a 1.3-percent average annual rate from 2005 to 2030.The most rapid growth in OPEC production is projected for Qatar.Oil Reserves and Resour
14、cesAs of January 1,2008,proved world oil reserves,as reported by the Oil&Gas Journal,were estimated at 1,332 billion barrels.The 56 percent of the worlds proved oil reserves are located in the Middle East.Among the top 20 reserve holders in 2008,11 are OPEC member countries that,Together,account for
15、 69 percent of the worlds total reserves.3 Natural Gas Worldwide,total natural gas consumption increases from cubic feet in 2005 to cubic feet in 2030 in the IEO2008 reference case.Natural gas consumption in the non-OECD countries grows more than twice as fast as consumption in the OECD countries,wi
16、th 2.3-percent average annual growth from 2005 to 2030 for non-OECD countries,compared with an average of for the OECD countries.North AmericaEUNON-OECDSupplyReserves and Resources Almost three-quarters of the worlds natural gas reserves are located in the Middle East and Eurasia.Russia,Iran,and Qat
17、ar together accounted for about 57 percent of the worlds natural gas reserves as of January 1,20084 Coal World coal consumption increases by 65 percent over the projection period,from 122.5 quadrillion Btu in 2005 to 202.2 quadrillion Btu in 2030.In 2005,coal accounted for 27 percent of world energy
18、 consumption.Of the coal produced worldwide in 2005,63 percent was shipped to electricity producers,34 percent to industrial consumers,and most of the remaining 3 percent went to coal consumers in the residential and commercial sectors.In 2005,Australia was the worlds leading coal exporter,supplying
19、 6.1 quadrillion Btu of coal to the international market,while Japan and South Korea were the worlds leading importers,receiving 4.5 and 1.9 quadrillion Btu of coal,respectively.More than one-half(53 percent)of Chinas coal use in 2005 was in the non-electricity sectors,primarily in the industrial se
20、ctor.China was the worlds leading producer of both steel and pig iron in 2005.World Coal Production China,Australia,the United States,and India dominate the overall trends for the OECD and non-OECD,accounting for 99 percent of the increase in net production for all the OECD countries and 82 percent
21、of the increase for the non-OECD countries.World Coal Reserves Total recoverable reserves of coal around the world are estimated at 930 billion tons.Although coal deposits are widely distributed,76 percent of the worlds recoverable reserves are located in five countries:the United States(28 percent)
22、,Russia(19 percent),China(14 percent),Australia(9 percent)and India(7 percent).5 Electricity World net electricity generation nearly doubles in the reference case,from 17.3 trillion kilowatthours in 2005 to 24.4 trillion kilowatthours in 2015 and 33.3 trillion kilowatthours in 2030.Nuclear Energy El
23、ectricity generation from nuclear power is projected to increase from about 2.6 trillion kilowatthours in 2005 to 3.8 trillion kilowatthours in 2030,China is trying to diversify its sources of electricity,and increasing nuclear power capacity is seen as a strategy to achieve that goal.Unlike most of
24、 the OECD nations,China will be able to expand its nuclear program largely without political deterrents.At present,China has 11 commercial nuclear power reactors in operation,6 of which have been brought on line since 2002.Another 6 plants are currently under construction,and several more are in var
25、ious stages of planning.The Chinese government is also in the process of awarding billions of dollars in contracts to build additional nuclear plants.Frances AREVA,Russias AtomStroyExport,and U.S.-based Westinghouse all have won bids.In the worlds largest nuclear power deal to date,China will pay$11
26、.9 billion to AREVA to build two nuclear reactors.China also has a number of large-scale hydroelectric projects under construction,including the 18,200-megawatt Three Gorges Dam project slated for completion at the end of 2008.The China Yangtze River Three Gorges Project Development Corporation alre
27、ady has announced it plans to increase its total installed capacity to 22,400 megawatts.In addition,work continues on the 12,600-megawatt Xiluodu project on the Jisha River(scheduled for completion in 2020 as part of a 14-facility hydropower development plan)and the countrys third-largest hydroelect
28、ric facility,the 6,300 megawatt Longtan project on the Hongshui River6 Transportation Sector Energy Consumption The transportation share of total liquids consumption increases from 52 percent in 2005 to 58 percent in 2030.Much of the growth in transportation energy use is projected for the non-OECD
29、nations,where many rapidly expanding economies are expected to see strong growth in energy consumption as transportation systems are modernized and rising standards of living increase the demand for personal motor vehicle ownership.Both China and India have become major vehicle manufacturers.In 2006
30、,China produced nearly 7.2 million motor vehicles,the third-highest production level in the world after Japan and the United States and more than one-tenth of the worlds total production.In 2007,motor vehicle production in China grew by another 22 percent,to 8.9 million vehicles.Within the next seve
31、ral years,Chinas production of motor vehicles may reach 10 million vehicles.7 Carbon Dioxide Emissions The average annual increase in non-OECD emissions from 2005 to 2030(2.5 percent)is five times the increase projected for the OECD countries(0.5 percent).In 2030,non-OECD emissions,projected at 26.8
32、 billion metric tons,exceed the projection for OECD emissions by 72 percent.In pre-industrial times,the concentration of carbon dioxide in the atmosphere was about 280 parts per million(ppm).The atmospheric concentration of carbon dioxide at present is about 380 ppm,and according to the IEO2008 refe
33、rence case projections,by 2030 it would be about ppm.2 Global Renewable Energy Status In 2007,more than$100 billion was invested in new renewable energy capacity,manufacturing plants,and research and developmenta true global milestone.Biomass and geothermal energy are commonly employed for both powe
34、r and heating,with recent increases in a number of countries,including uses for district heating.More than 2 million groundsource heat pumps are used in 30 countries for building heating and cooling.Production of biofuels(ethanol and biodiesel)exceeded an estimated 53 billion liters in 2007,up 43 pe
35、rcent from 2005.Ethanol production in 2007 represented about 4 percent of the 1,300 billion liters of gasoline consumed globally.Annual biodiesel production increased by more than 50 percent in 2006.Renewable energy,especially small hydropower,biomass,and solar PV,provides electricity,heat,motive po
