1、energy in transition 能源的轉(zhuǎn)變the era of cheap and convenient sources of energy is coming to an end. a transition to more expensive but less polluting sources must now be managed. 能源資源價格低廉、使用便捷的時代已經(jīng)過去，目前應(yīng)向盡管價格較高、但污染較小的資源轉(zhuǎn)變。john p . holdren1. understanding this transition requires a look at the two-sided

2、 connection between energy and human well-being. energy contributes positively to well-being by providing such consumer services as heating and lighting as well as serving as a necessary input to economic production. but the costs of energy including not only the money and other resources devoted to

3、 obtaining and exploiting it but also environmental and sociopolitical impacts detract from well-being.了解這一轉(zhuǎn)變，需首先看一看能源和人類幸福的雙重關(guān)系。從積極的意義上說，能源為人類幸福作出了貢獻(xiàn)，它為經(jīng)濟(jì)生產(chǎn)活動提供必要投入的同時，也提供了諸如取暖、照明等消費(fèi)服務(wù)。然而， 人類為利用能源所付出的代價卻削弱了能源為其帶來的利益，這種代價不但包括為獲取和利用能源所投入的資金和其他資源，而且包含了能源開發(fā)和利用所產(chǎn)生的環(huán)境影響和社會政治影響。2. for most of human histor

4、y, the dominant concerns about energy have centered on the benefit side of the energy well-being equation. inadequacy of energy resources or (more often) of the technologies and organizations for harvesting, converting, and distributing those resources has meant insufficient energy benefits and henc

5、e inconvenience, deprivation and constraints on growth. the 1970s, then, represented a turning point. after decades of constancy or decline in monetary costs and of relegation of environmental and sociopolitical costs to secondary status energy was seen to be getting costlier in all respects. it beg

6、an to be plausible that excessive energy costs could pose threats on a par with those of insufficient supply. it also became possible to think that expanding some forms of energy supply could create costs exceeding the benefits. 人類歷史發(fā)展長河中，人們主要關(guān)心的是能源和人類安康等式關(guān)系中有利的一面。能源資源不足或者（更經(jīng)常）開采、加工和分配這些資源所需技術(shù)與機(jī)構(gòu)的不足

7、，會影響能源為人類帶來利益， 同時意味著能源的增長遭到干擾、損害或限制。到了20 世紀(jì) 70 年代，出現(xiàn)了一個轉(zhuǎn)折點(diǎn)。此前的幾十年中，能源的資金成本一直保持穩(wěn)定，甚或有所下降，而且，其所牽扯的環(huán)境成本和社會政治成本一直處于次要地位。但20 世紀(jì) 70年代開始，開發(fā)和利用能源的多方成本均顯著增長。人們自然有理由認(rèn)為：高昂的能源成本所帶來的威脅已同能源供應(yīng)不足所產(chǎn)生的危險不相上下。同時，也有人擔(dān)心，依靠擴(kuò)大能源資源增加供應(yīng)所需付出的代價，也許大于其所帶來的利益。3. the crucial question at the beginning of the 1990s is whether the

10、 of dirty coal as well as clean; undersea oil as well as terrestrial; deep gas as well as shallow; mediocre hydroelectric sites as well as good ones; and deforestation as well as sustainable fuelwood harvesting. 20世紀(jì) 90年代初期人們關(guān)注的焦點(diǎn)在于這種始于70年代的能源發(fā)展趨勢是暫時的還是長遠(yuǎn)的。 廉價能源時代是真正一去不復(fù)返，還是通過開發(fā)新能源、應(yīng)用新技術(shù)、改革地緣政治秩序等措施

11、，有可能重登歷史舞臺？回答這個問題的一個關(guān)鍵因素是過去100年以來因人口空前增長帶來令人瞠目的能源需求以及同樣使人無從應(yīng)對的人均工業(yè)能源需求。急劇增長的能源需求使得人類對能源的使用無所不用其極：不管是清潔煤炭還是劣質(zhì)煤炭，見煤就挖；無論是陸上石油還是海底石油，深層氣還是淺層氣，見油氣就采；水電站建設(shè)不論適宜與否，見水就上；一邊綠化造林以求燃料樹木可持續(xù)發(fā)展，一邊卻砍樹毀林。4. except for the huge pool of oil underlying the middle east, the cheapest oil and gas are already gone. even i

12、f a few more giant oil fields are discovered, they will make little difference against consumption on todays scale. oil and gas will have to come increasingly, for most countries, from deeper in the earth and from imports whose reliability and affordability cannot be guaranteed. 除了中東地區(qū)蘊(yùn)藏著巨大的石油資源， 地球

13、上廉價的油氣資源已經(jīng)不復(fù)存在。即使偶爾找到幾個大油田，同當(dāng)今巨大的能源消耗相比，也是杯水車薪。對于大多數(shù)國家來說，油氣資源越來越多地依賴于深層埋藏，越來越多地依賴進(jìn)口，且不說進(jìn)口油氣資源的可靠性無法得到保障，其對進(jìn)口國的支付能力也是一個考驗(yàn)。5. there are a variety of other energy resources that are more abundant than oil and gas. coal, solar energy, and fission and fusion fuels are the most important ones. but they al

14、l require elaborate and expensive transformation into electricity or liquid fuels in order to meet societys needs. none has very good prospects for delivering large quantities of electricity at costs comparable to those of the cheap coal-fired and hydropower plants of the 1960s. it appears, then, th

15、at expensive energy is a permanent condition, even without allowing for its environmental costs. 誠然，其他許多資源的儲藏量大于石油和天然氣，最重要的有煤、太陽能、聚變裂變?nèi)剂系?。但這些資源轉(zhuǎn)化成電力或液體燃料，以滿足社會需求，均需經(jīng)過技術(shù)復(fù)雜、成本昂貴的轉(zhuǎn)化過程。同 20 世紀(jì) 60 年代成本低廉的燃煤火電站和水力發(fā)電站相比，僅從成本角度考慮，以上各種資源用于大規(guī)模發(fā)電的可能性極小。因此，即使不考慮能源開采的環(huán)保成本，能源價格居高不下已成無可改變的定局。6. the capacity of the

18、ducing the external costs. 環(huán)境吸納由于能源利用而產(chǎn)生的廢棄物和其他影響的能力本身也是有限度的，表現(xiàn)在兩方面的環(huán)境成本上。所謂“ 外延成本 ” 即由于環(huán)境遭到破壞對社會產(chǎn)生的影響，但尚未反映到能源買賣雙方的交易價格上；所謂“ 內(nèi)涵成本 ”即為降低外延成本而采取各種措施（如污染防治措施）所引起的資金成本的增長。7. both types of environmental costs have been rising for several reasons. first, the declining quality of fuel deposits and energy-

20、uch effluents without disruption. third, the monetary costs of controlling pollution tend to increase with the percentage of pollutants removed. 兩種環(huán)境成本均一直呈增長趨勢，原因是多方面的。首先，社會發(fā)展所依賴的燃料礦藏和加工地質(zhì)量下降，必然要求礦物運(yùn)輸和加工的數(shù)量增加、設(shè)施擴(kuò)大、運(yùn)輸距離延長。第二，利用能源所產(chǎn)生的廢棄物不斷增加，使得環(huán)境不遭破壞地吸納廢棄物的能力達(dá)到了極限。第三，污染防治所需的資金成本亦將隨著消除污染源比例的提高而提高。8. de

21、spite these expenditures, the remaining uninternalized environmental costs have been substantial and in many cases are growing. those of greatest concern are the risk of death or disease as a result of emissions or accidents at energy facilities and the impact of energy supplied on the global ecosys

22、tem and on international relations. 盡管代價高昂，尚未內(nèi)化的環(huán)境成本一直居高不下，并在許多情形下呈增長趨勢，其中最引人關(guān)注的是由能源設(shè)施排放廢物或發(fā)生事故所帶來的死亡和疾病，以及由于能源供應(yīng)對于全球生態(tài)系統(tǒng)和國際關(guān)系所造成的影響。9. the impacts of energy technologies on public health and safety are difficult to pin down with much confidence. in the case of air pollution from fossil fuels, in wh

29、ligible to substantial in comparison with other risks to the population. there is little basis, in these ranges, for preferring one of these energy sources over the other. for both, the very size of the uncertainty is itself a significant liability. 同人類所面臨的其他威脅相比，火電廠和核電廠危害大眾健康的程度究竟多大，眾說紛紜，莫衷一是。有的人認(rèn)為

30、這種影響微不足道，可以忽略不計(jì)；也有人認(rèn)為這種影響程度嚴(yán)重、危害巨大。無論影響大小，都沒有理由對其中種種能源親此疏彼。無論是核電還是火電，其對人類的危害都無法確定，這本身就是一大憾事。12. often neglected, but no less important, is the public health menace from traditional fuels widely used for cooking and water heating in the developing world. perhaps 80 percent of global exposure to parti

36、 a striking share of the environmental impacts of human activity. the environmental transition of the past 100 years driven above all by a 20-fold increase in fossil-fuel use and augmented by a tripling in the use of traditional energy forms has amounted to no less than the emergence of civilization

41、. one such threat is the potential for conflict over access to petroleum resources. another threat is the link between nuclear energy and the spread of nuclear weapons. the issue is hardly less complex and controversial than the link between co2 and climate; many analysts, including me, think it is
