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
