现状:人均占有量少。利用率不高。特点:一、能源资源总量比较丰富。中国拥有较为丰富的化石能源资源。其中,煤炭占主导地位。2006年,煤炭保有资源量10345亿吨,剩余探明可采储量约占世界的13%,列世界第三位。已探明的石油、天然气资源储量相对不足,油页岩、煤层气等非常规化石能源储量潜力较大。中国拥有较为丰富的可再生能源资源。水力资源理论蕴藏量折合年发电量为6.19万亿千瓦时,经济可开发年发电量约1.76万亿千瓦时,相当于世界水力资源量的12%,列世界首位。二、人均能源资源拥有量较低。中国人口众多,人均能源资源拥有量在世界上处于较低水平。煤炭和水力资源人均拥有量相当于世界平均水平的50%,石油、天然气人均资源量仅为世界平均水平的1/15左右。耕地资源不足世界人均水平的30%,制约了生物质能源的开发。 三、能源资源赋存分布不均衡。中国能源资源分布广泛但不均衡。煤炭资源主要赋存在华北、西北地区,水力资源主要分布在西南地区,石油、天然气资源主要赋存在东、中、西部地区和海域。中国主要的能源消费地区集中在东南沿海经济发达地区,资源赋存与能源消费地域存在明显差别。大规模、长距离的北煤南运、北油南运、西气东输、西电东送,是中国能源流向的显著特征和能源运输的基本格局。 四、能源资源开发难度较大。与世界相比,中国煤炭资源地质开采条件较差,大部分储量需要井工开采,极少量可供露天开采。石油天然气资源地质条件复杂,埋藏深,勘探开发技术要求较高。未开发的水力资源多集中在西南部的高山深谷,远离负荷中心,开发难度和成本较大。非常规能源资源勘探程度低,经济性较差,缺乏竞争力。

Fully understand the importance of energy-saving emission reduction Strong typhoons, dust storms, high temperatures and drought, extreme precipitation ... ... In recent years, frequent episodes of extreme weather worldwide, more serious harm. The reason is one of the most important and inescapable responsibility of mankind is too much carbon-based fuel consumption resulting from extreme weather events to global warming --- the problem is only a refraction of the energy consumption only. Chinese Academy of Sciences survey shows that China is the world's natural resources and waste of the most serious one of the countries surveyed in the 59 countries ranked No. 56. According to statistics, China's energy efficiency is only 26.9% of the United States, Japan's 11.5%. Therefore, to promote energy-saving emission reduction can be described as imminent. It is reported that the country's total energy use by more than half of industrial production, particularly in electrical equipment manufacturing industry, its energy usage is not optimistic. Although we are constantly elimination of outdated equipment technology to improve energy efficiency, but a large number of inefficient technologies are still widespread in our factory in. China has more than 500 million kilowatts of electric, they consume 80 billion a year to 1000 million kilowatt-hours of energy, accounting for 75% of industrial energy consumption, total energy consumption by 60%. Of these, 70% used to drive blowers and pumps, the total reached 250 million kilowatts of electric, you should use the variable speed drive. But the fact is that only 20% of the use of variable speed drives --- a huge waste of electricity goes without saying. In the "Eleventh Five-Year Plan", our government energy efficiency a top priority. In the next 15 years, our country is more committed to China from the current inefficient energy users to become efficient energy users. However, to improve the status of energy consumption, but also need electricians and equipment to the coal, petroleum, construction and other industries to make unremitting joint efforts. Reduce energy consumption, electrical equipment industry responsibility. In the elimination of outdated equipment at the same time, companies should learn from foreign advanced management experience and technology. Weihai Power Plant, such as the help of Rockwell Automation in the field of power generation solutions that will reduce energy consumption by 45%; and Guangxi Liuzhou Iron and Steel Plant, but also through automation, reducing 63% of electricity consumption in the energy saving on the has achieved immediate results. In addition, to ensure that energy efficiency and energy management on the rise, progress, and personnel training is also crucial. Therefore, the energy consumption can not be merely in a purely industrial production, but also extends to the upper reaches of the personnel training, extended to our higher education is to constantly increase the energy efficiency and energy management courses, teaching standards, and make it more close to China's market demand. Energy-saving emission reduction, the need to promote energy structure adjustment. However, as long as China's economy continues to move forward, we need to constantly increase their energy, so in a given period, thermal power generation as a primary energy continues to occupy a certain proportion. September 6, Chinese President Hu Jintao at the APEC Business Summit in his speech that the Chinese government has formulated and published the National Climate Change Program, has taken to improve energy efficiency, improve energy structure, a series of measures to strengthen ecological protection, and established the the year 2010 the forest coverage rate increased from 18.2% at the end of 2005 increased to 20% of such objectives. According to expert estimates, from 1980 to 2005, China's afforestation activities in the amount of net absorption of about 3.06 billion tons CO2. Can be seen that deal with global warming, reducing CO2 emissions, afforestation projects are an effective solution.

经过上个世纪后五十年的持续努力,特别是改革开放以来的快速发展,中国能源建设取得了巨大成就,能源供应已经从多年的严重短缺,转到总量基本平衡,能够适应国民经济和社会发展的需要。主要表现在以下五个方面: 1、能源产量迅速增加,供应有保证。 2000年中国一次能源生产量达到10亿9千万吨标准煤,其中原煤9亿9千8百万吨,原油1亿6千3百万吨,天然气277亿立方米,发电量13,500亿千瓦时;太阳能、风能、地热等新能源也都有不同程度的发展。 2、能源消费结构不断优化,能源供应质量有所提高。煤炭消费量在一次能源消费总量中所占的比重,已由1990年的762%降为2000年的66.0%;石油、天然气、水电、核电、风能、太阳能等所占比重,由1990年的23.8%上升到2000年的34.0%。洁净能源的迅速发展,优质能源比重的提高,为提高能源利用效率和改善大气环境起了重要的作用。 3、能源产业的现代化程度进一步提高,技术水平上了一个新台阶。煤炭工业已具备设计、施工、装备及管理千万吨级露天煤矿和大中型矿区的能力;石油工业已形成从勘探开发、地面工程建设到装备制造的完整体系;电力工业发展进入了以大机组、大电厂、大电网、超高压和自动化为主要特征的新阶段。 4、能源工业管理体制改革顺利推进,市场化程度不断提高。煤炭价格已放开,煤炭生产、运输和销售全面进入市场。为打破行业垄断,推动有序竞争,石油天然气工业和石油化工工业通过重组,实行了勘探开发、加工利用、内外贸一体化,原油、成品油价格与国际市场接轨。电力工业已确立"厂网分开、竞价上网,健全合理的电价形成机?quot;的改革目标。通过这一系列的改革,中国能源市场化程度进一步提高,中国能源工业将适应WTO的各项要求,更好地参与经济全球化。 5、节能工作成绩显著。"九五"计划时期,万元国内生产总值能耗下降了30%,节约和少用能源约4亿吨标准煤,相当于减少排放二氧化硫800万吨、二氧化碳1亿8千万吨、粉尘600万吨、灰渣1亿吨。节能工作的成效,缓解了能源供需矛盾,减少了对环境的负面影响。 中国能源发展虽然获得了长足进步,但仍存在着一些深层次的问题。一是能源品种结构不合理,煤炭直接用于终端消费的比例过大,天然气、风能、太阳能等洁净能源所占比重过低。二是技术水平不高,洁净煤技术开发与应用落后。三是能源利用效率、环保措施与世界先进水平相比有较大差距,不能完全满足可持续发展的要求。
