noun

 nuclear/solar energy 核能；太陽能She's always full of energy. 她總是充滿活力。energy ♦︎ powerThese are both words for the fuel, strength of the sun or wind, etc. that is used to drive machines, make electricity, provide heat, etc. 這兩個詞均表示能源。PATTERNS AND COLLOCATIONS 句型和搭配◆electrical / nuclear / atomic / solar / wind / tidal energy / power◆to generate / produce / provide / supply / use / harness energy / power◆an energy / a power supply◆a source of energy / power■ energy [uncountable] a source of power such as fuel, used for driving machines, providing heat, etc. 能源◆the change from fossil fuel to renewable energy從化石燃料到可再生能源的轉變◆The nuclear plant provides a fifth of the nation's energy.核電廠爲該國提供五分之一的能源。◆It is important to conserve energy.節能十分重要。◆Energy-saving features can reduce energy bills by 50%.這些節能特性能降低能耗支出50%。◆The country could face an energy crisis (= when fuel is not freely available) if demand continues to rise.如果需求持續上升，這個國家可能會面臨能源危機。ⓘ In physics energy is the ability of matter or radiation to work because of its mass, movement, electric charge, etc. 物理學中，energy指物質或輻射因其質量、運動或所帶電荷而具有的做功的能力◆kinetic / potential energy動能；勢能 ■ power [uncountable] energy that can be collected and used to operate a machine, to make electricity, etc.; the public supply of electricity 能量；動力；電力供應◆Wind power was used to drive the machinery.用了風能來驅動機器。◆This wheel provides the power to the cutting machine.這個輪子爲剪切機提供動力。◆To go higher the pilot increases the engine power.爲了能飛得更高，飛行員加大了發動機的動力。◆They've switched off the power.他們關掉了電源。◆There seems to have been a power failure.好像停電了。NOTE 辨析 Energy or power? Energy is the source of power: the fuel, the light and heat from the sun or a nuclear reaction, the strength of the wind, water or waves. Power is energy that has been collected and used to produce electricity, operate machinery, etc. In practice you can often use either word. * energy指能源，諸如燃油、太陽或核變産生的光和熱，以及風、水或潮汐的能量。power指蓄集起來用於發電、驅動機器等的能量。實際上，兩個詞常可通用◆electrical / nuclear / atomic / solar / wind / tidal energy / power電能；核能；原子能；太陽能；風能；潮汐能◆to generate / produce / provide / supply / use / harness energy / power發電；産生能量；提供能量；供電；使用能量；利用能量However, although you can say generate/produce energy, energy is often seen as sth that cannot be created (and in a scientific sense this is true): you can store, conserve or save energy, or you can waste it. Power is less frequently seen in this way: you generate/produce power and then use it to drive sth, but it is less usual to talk about storing or saving it. The energy supply is all the energy that has not yet been used up; the power supply is the continuous flow of power to where it is being used. 不過，盡管“發電”可以說成generate/produce energy，energy常被認爲是不能人爲制造産生的，而且從科學意義上講確實如此。與energy搭配的動詞有store、conserve、save和waste。power較少這樣用，常與之搭配的動詞有generate和produce。use power to drive sth指使用能量驅動某物。power通常不與表示貯存或節約意義的詞連用。energy supply指至今還沒有耗盡的所有能源，power supply指能量的持續供應◆The world's energy supply is heading for crisis.世界正瀕臨能源供給危機。◆The world's power supply is heading for crisis. ◆interruptions in the power supply電力供應的中斷◆interruptions in the energy supply energy2
