What did hesun, wind, water, and so renewable energy sources are promising, an international confederation of scientists and engineers is working feverishly to overe the various obstacles associated with these “new energy” major challenge is to develop efficient and economically workable versions of these ？在我們完善冷聚變技術(shù)之前，我們只能專注于開發(fā)太陽能、風(fēng)能、水電能之類的可再生能源，并提高其產(chǎn)量。雖然可再生能源前景樂觀，一個由科學(xué)家和工程師組成的國際聯(lián)盟卻正在積極工作，努力克服與這些“新興能源”技術(shù)相關(guān)的各種障礙，其中最大的挑戰(zhàn)就是如何使這些技術(shù)變得既高效又經(jīng)濟。Take solar energy for is a good option because there is an unlimited supply of glittering it work on a large scale, however, is much easier said than would be cost prohibitive to take the intricate gadgets of solar energy from the fringe of “green” society to the mainstream for major world solar apparatus itself is ready for many new business and consumer applications, but it is way too expensive to replace the old bustion machinery of gears and motors with new electronic technology of semiconductors and transistors on a global or even a national 。由于耀眼的太陽光能夠提供源源不斷的能源，所以它是個不錯的選擇。但是，大規(guī)模地使用太陽能卻是說起來容易做起來難。把制造太陽能所需要的復(fù)雜零件從“環(huán)?！鄙鐣倪吘壨茝V到主流社會，使之成為世界主要的消費性能源，其代價之高讓人望而卻步。太陽能設(shè)備本身已是技術(shù)成熟，可以使商業(yè)和消費者進行許多新型應(yīng)用，但是，在全球或者即便是在全國范圍內(nèi)，用新型的半導(dǎo)體和晶體管電子技術(shù)取代老式的用齒輪和發(fā)動機驅(qū)動的燃燒設(shè)備，其成本實在太高。Wind power, which has been used effectively in some places for generations, is also rapidly growing in the energy principle behind it is that wind converts rotary force into electricity by turning the blades of the turbine clockwise or counterclockwise around an , wind power is very unreliable and its strength depends on local weather patterns, temperature, time of year, and addition to this unreliability, wind power equipment is very expensive pared with other energy sources and won39。t bee a viable alternative until we can slash the costs , a “wind farm” requires enormous land clearing to produce significant amounts of ，目前在能源市場中也發(fā)展迅速。風(fēng)能的原理是：風(fēng)通過驅(qū)動渦輪機葉片按順時針或逆時針方向繞著一個軸旋轉(zhuǎn)，從而把轉(zhuǎn)動時所產(chǎn)生的力轉(zhuǎn)換成電能。不幸的是，風(fēng)能非常不穩(wěn)定，其強度取決于當?shù)氐奶鞖饽Ｊ健囟?、季?jié)以及地域。除了不穩(wěn)定的因素之外，和其他能源相比，風(fēng)能設(shè)備造價昂貴。除非我們能將其成本大大降低，否則風(fēng)能就不會成為一個可行的替代能源。而且，一個“風(fēng)能農(nóng)場”需要大片空曠的土地才能生產(chǎn)大量能源。Hydroelectric power is another source of clean and renewable can be harnessed by controlling the natural outflow of water with different most popular is through dams, which, unfortunately, are no longer considered environmentally of the hydroelectric dams in the world are historically recent, but all reservoirs eventually will fill up with mud and require very expensive excavation to clear them up to bee useful 。人們可以通過不同方法來控制自然水流以進行發(fā)電。最普遍的方法是通過水壩，但不幸的是，建水壩已被認為是對環(huán)境不利的方法了。世界上大多數(shù)用于水力發(fā)電的大壩建造歷史都不長，但是所有的水庫最終都會被淤泥填塞，需要耗資巨大進行清淤才能使它們重新得到利用。Biomass energy derived from plant and animal matter is still another renewable source being considered as a standby replacement for fossil waste in the form of dead trees, leaves, animal corpses and food processing waste exists in abundance and can be used to produce , there is no way to ventilate the direct burning of biomass as fuel without diffusing carbon dioxide and other greenhouse gases into the gases can pose a risk to the ozone layer, increasing overall exposure of human beings to harmful UV rays from the , it takes time and money to collect and transport biomass in its raw form to a central point for processing into fuel, and the automation of such a process is too , for the time being, biomass has too many costly drawbacks to be a workable alternative to fossil ，且被認為是礦物燃料的備用替代品。以死樹、枯葉、動物尸體以及食品加工廢料的形式存在的有機廢物十分充足，可以被用來制造能源。然而，將生物質(zhì)作為燃料直接燃燒，通風(fēng)時必然會將二氧化碳及其他溫室氣體排放到大氣中。這些氣體會對臭氧層造成威脅，增加人們受到來自太陽的有害紫外線照射的危險。除此以外，將生物質(zhì)以原始形態(tài)進行收集，并將它們運送到某個中心站加工處理成燃料，這一過程既耗時又耗財，而且對這一過程實現(xiàn)自動化非常困難。所以，在目前，生物質(zhì)能源有太多高成本方面的缺點，不能成為礦物燃料可行的替代品。Although renewable energies are not yet economically petitive with fossil fuels, their price bees more attractive when pared with the health and environmental costs associated with burning coal and the best solution to our growing energy challenges es in a bulletin from the Union of Concerned Scientists: “Our society39。s future success cannot hinge on one single answer instead must e from a family of diverse energy technologies that share a unified purposethey do not deplete our natural resources or destroy our environment.” Despite the difficulties, it is important to remember that an energy crisis is appro
