The area is small to the highest ( conversion efficiency 13 - 15%, some have achieved more than 20%) of monocrystalline silicon solar energy cell conversion efficiency, and output power is big, and stability is good, grows ( generally can reach more than 20 years ) service life, but the raw and processed material cost height, the weak light specific property is wronger, and production technology is complicated, hence the selling price is also higher; The polycrystalline silicon solar energy cell is basic identical with the function characteristic of monocrystalline silicon solar energy cell; The conversion efficiency of non- brilliant silicon solar cell than hangs down ( simples about 6 - 8%), the area is than greatly, but because of his raw and processed material cost than hanging down, can be easy to big area industrialize production, what will have hope to be used the generally big area to generate electricity from now on most will be this kind of application that battery is along with manufacture technique and new material, in a single day the practical package photoelectricity conversion efficiency of its big area achieves more than the 10-15%, and the price of every tile electric power-generating equipment is fallen 1 - 2 U.S.dollar of time, and just is enough to that the solar energy cell efficiency that big area the getting extensive use will constantly replace in now convention certainly special use and the laboratory of sources of energy s will high get many.

单晶硅太阳能电池转换效率最高（转换效率13～15%，有的已达到20%以上），面积小，输出功率大，稳定性好，使用寿命长(一般可达20年以上)，但原材料成本较高，弱光特性较差，生产工艺复杂，故售价也较高；多晶硅太阳能电池与单晶硅太阳能电池的性能特点基本相同；非晶硅太阳能电池的转换效率较低（约6～8%左右），面积较大，但因其原材料成本较低，可便于大面积工业化生产，今后最有希望用于一般大面积发电的将是这种电池。随着制造技术和新材料的应用，一旦它的大面积实用组件光电转换效率达到10-15%以上，每瓦发电设备的价格降到1～2美元时，便足以大面积得到广泛应用并将不断取代现在常规能源。当然特殊用途和实验室中的太阳能电池效率要高得多。

This kind of oceanic energy has allured the most attentions in the field of oceanic energy utilization.

针对海洋波浪能发电技术的基本原理、能量转换系统等作了全面综述，介绍了国内外海洋波能发电技术的进展和主要波能装置，而其中一些计划的成功实施，有力地推动了波能转换的技术进步及其在世界范围内的竞争力。

It only took 38 months from construction preparation at the end of October, 2001 to the first unit operating on December 20, 2004, which antedated the construction time limit by 7 months. During the period, 5-month-construction period delayed was saved because of the karst geological problems of dam's partial foundation. 3 units were put into operation in 2005, especially it only took 23 days from the runner of 4# unit hoisted to put into operation. It created the wonder of installing large axial-flow feathering unit.

乐滩电站从2001年10月底开始施工准备到2004年12月20日首台机组投产发电，仅用38个月的时间，比合理工期提前了7个月，并在此期间，抢回因厂坝部份地基岩溶地质问题延误的5个月工期。2005年又实现了年内3台机组投产发电，尤其4号机组从转轮吊装到机组并网发电，仅用23天，创造了大型轴流转桨机组安装奇迹。

Circumrotating the crank, the acceleration device changes the rotation speed of the crank into higher rotation speed and impresses onto the direct current dynamo. Thus, the electric power could be stored in the storage battery.

利用人力为微型计算机发电可实现一举多得：人力发电对环境没有任何污染，微型计算机用户还可以实现强身健体的目的，可使微型计算机免受停电之扰，大大减轻电网负荷。

Waxing crankier, Owen takes some digs at solar power , net metering (which gives people credit for wind or solar power they deliver back to the grid) and distributed generation: he claims they spur growth and consumption in the 'burbs, though he doesn't give their proponents a chance to rebut his charges, and many of his assertions have a "just so" flavor.

打蜡，欧文发生在太阳能发电一些挖掘，净计量（赋予人民对风能和太阳能它们提供回格信贷）和分布式发电：他声称，他们促进增长和；芳邻消费，但他吨给他们的支持者有机会反驳他的指控，他的许多主张&正义等&的味道。

Ocean Energy—Hydroelectric energy, from the damming of rivers, has been around for a long time.

海洋能源—透过建造水库利用河川水力进行发电，已是相当古老的发电方式。

Compared to the traditional power,the wind power can be taken as widely-distributed,clean and sustainable energy which gets rid of the dependence on nonrenewable fossil energy and defuses the fuel cost risk of normal power so as to ensure the cost stability of power generation,which basically solves the environmental cost of discharge of sulfur,dust and carbon caused by the normal power.

与传统能源相比，风能作为一种在全球范围内广泛分布的清洁、永续能源，其有效利用不仅可以摆脱对不可再生的化石能源的依赖，化解常规电力的燃料价格风险，保证发电成本的稳定，而且可以从根本上解决常规能源发电所带来的硫、粉尘、碳排放等环境成本问题。
