Solar energy The solar energy supply continuously, is one kind of extremelyclean energy, cannot cause the pollution, cannot exhaust the naturalresource or cause the whole world greenhouse effect. The solar energy merit, is may obtain in Earth's all places, moreoverthe usability high, the use are many. Modern solar energy system, indaily sunshine time quite short country, also may the economyeffectively provide the massive electrical energies. The solar energy science and technology, the application is reallybroad. For example the solar energy computer, the wristwatch, are verycommon in the market condition. Moreover, the water heater and the solar room which actuates using thesolar energy, also obviously arrives in the foreign country many, butin Hong Kong not Yi seete. But the solar energy transportationvehicle, also has the research development in some technical moreadvanced countries, for example US, Japan. These transportationvehicles including airplane, automobile. Actually, the greenhouse sun's energy storing in a space, can continuethe plant to grow. Nowadays the humanity most pays attention the energy question, thesolar power plant also can the help solve.
Nuclear power The nuclear power electricity generation, is has the hugeenergy using the nuclear fission, the manufacture high temperaturehigh pressure vapor or the gas, the actuation power set electricitygeneration. The nuclear power uses the fuel, is may split or the fusionradioactive substance, for example uranium, uranium and so on.For example the gram uranium crack produces can be equal to burns thequantity of heat which 3,000 tons superior coals produces. At present the nuclear power power rate only occupies the globalenergy and the electric power supply 7% and 17. Hydraulicelectrogenerating Carries on the electricity generation with the water power, isby the artificial method, the guidance current of water by the highvelocity impact hydraulic turbine, drives the hydraulic turbine andgenerator revolving, thus has the electric power. Therefore, generallyin the hydroelectric power station upstream, constructs the dam and蓄水庫, the savings water volume, enhances the dropping variance(flood peak). Hydraulic electrogenerating The hydraulic electrogenerating regenerates the energy, issmaller to the environment impact. Besides provides the inexpensiveelectric power, but also has the following merit: The control flood氾 overflows, to provide the irrigation water used, to improve therivers shipping, the related project simultaneously improves thislocal the transportation, the electric power supply and the economy,specially may develop the tourism and the aquaculture. The AmericanTennessee River's synthesis development plan, is the first large-scalehydraulic engineering, the impetus whole economical development.
Wind power energy The wind power can generally refer to the electric power whichwind power turbine penetration natural air transport produces. It issaid the first automatic electricity generation wind power turbine wasinvents in 1887 by American Charlie Si. The hereafter in 1918, theDanish 120 public utilities all has approximately installed the windpower turbine, this stimulated the wind power to be able development.Today, the whole world probably has 35,,000 electricity generationswind power turbine.

Supply of solar energy continually, one clean energy very, can cause pollution, will not exhaust the natural resources or cause the global greenhouse effects .
The advantage of the solar energy, can be got in all places of the earth, and practicability is high, uses are many. The modern solar energy is systematic, in quite short country of sunshine time of every day, can offer a large amount of electric energy economically effectively too.
Science and technology of the solar energy, it is very wide to use. Such as the calculator , wrist-watch of the solar energy, very general on the market.
In addition, water heater and the sun room made use of solar energy to drive, can also see much in foreign country, but difficult to see in Hong Kong. And the means of transportation of the solar energy, also study development in some countries with more advanced science and technology, such as U.S.A. , Japan. The means of transportation includes plane , automobile.
In fact, the greenhouse stores the energy of the sun in a piece of space, make the plant grow continuously.
The energy question which the mankind pays close attention to most now, the power plant of solar energy can also help to solve .
The nuclear energy generates electricity, utilizing cores to split , degree produces enormous energy , make the vapour or gas of the high-temperature high pressure , urge the generating set to generate electricity.
Fuel that the nuclear energy uses, it is a radioactive material that can be split or merged, such as uranium , Bu , uranium ,etc.. For example grams of uranium split produce be able to is it burn 3000 first-class heat that coal produce to equivalent to.
Generation of nuclear energy only accounts for 7% and 17 of global energy and supply of electric power at present. Hydroelectric generation
Generate electricity with water conservancy, lead the rivers to strike the hydraulic turbine at the high speed , drive the rotation of hydraulic turbine and generator with the artificial method , thus produced the electricity . So, generally the top in the power station, build the dam and storage reservoir , the water yield of the savings, improve the drop (flood peak).

The hydroelectric generation is the recycled energy, it is relatively small to strike the environment. Besides offering the low-priced electricity , there are the following advantages : Control the flood and overflow, offer and irrigate the water, improve river shipping, improve the traffic , supply of electric power and economy of this area at the same time about the project, can especially develop the tourist industry and aquaculture . The comprehensive development plan of the river of Tennessee of U.S.A., is the first and large-scale irrigation works, drive the economic development of the whole .
Wind-force can point but electricity that produced wind-force turbine flow. It is said the first wind-force turbine generating electricity automatically was invented by the American Charles in 1887. Have thereafter installed the wind-force turbine in about 120 public utilities in Denmark in 1918, this development that can stimulate wind-force . Today, probably 35,000 generate electricity wind-force turbines in the whole world.
