能源用英语定义怎么说

Energy is the ability to do work or produce change. It is a fundamental concept in physics, and can be defined as the capacity to perform physical or chemical transformations, or to transmit information. Energy exists in many forms, such as kinetic energy (the energy of motion), potential energy (stored energy), thermal energy (the energy of heat), and electromagnetic radiation (such as light). Energy can be converted from one form to another, and it is an essential component of many natural and man-made systems.
