noun

 nuclear/solar energy 核能；太阳能She's always full of energy. 她总是充满活力。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. 这两个词均表示能源。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从化石燃料到可再生能源的转变◆The nuclear plant provides a fifth of the nation's energy.核电厂为该国提供五分之一的能源。◆It is important to conserve energy.节能十分重要。◆Energy-saving features can reduce energy bills by 50%.这些节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.如果需求持续上升，这个国家可能会面临能源危机。ⓘ In physics energy is the ability of matter or radiation to work because of its mass, movement, electric charge, etc. 物理学中，energy指物质或辐射因其质量、运动或所带电荷而具有的做功的能力◆kinetic / potential energy动能；势能 ■ power [uncountable] energy that can be collected and used to operate a machine, to make electricity, etc.; the public supply of electricity 能量；动力；电力供应◆Wind power was used to drive the machinery.用了风能来驱动机器。◆This wheel provides the power to the cutting machine.这个轮子为剪切机提供动力。◆To go higher the pilot increases the engine power.为了能飞得更高，飞行员加大了发动机的动力。◆They've switched off the power.他们关掉了电源。◆There seems to have been a power failure.好像停电了。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，诸如燃油、太阳或核变产生的光和热，以及风、水或潮汐的能量。power指蓄集起来用于发电、驱动机器等的能量。实际上，两个词常可通用◆electrical / nuclear / atomic / solar / wind / tidal energy / power电能；核能；原子能；太阳能；风能；潮汐能◆to generate / produce / provide / supply / use / harness energy / power发电；产生能量；提供能量；供电；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. 不过，尽管“发电”可以说成generate/produce energy，energy常被认为是不能人为制造产生的，而且从科学意义上讲确实如此。与energy搭配的动词有store、conserve、save和waste。power较少这样用，常与之搭配的动词有generate和produce。use power to drive sth指使用能量驱动某物。power通常不与表示贮存或节约意义的词连用。energy supply指至今还没有耗尽的所有能源，power supply指能量的持续供应◆The world's energy supply is heading for crisis.世界正濒临能源供给危机。◆The world's power supply is heading for crisis. ◆interruptions in the power supply电力供应的中断◆interruptions in the energy supply energy2
