能量存在形态不同,其来源也不同。一般将能源分为两种:不可再生能源和可再生能源。不可再生能源是指那些一旦被消耗,在短时间内不可能再恢复的能源,如煤炭、石油和天然气等。可再生能源又叫可更新能源,如风能、潮汐能、太阳能和水能,这些能源“取之不尽,用之不竭”。由于在使用过程中对环境不会造成污染,所以也被称为清洁能源。因为地球上的不可再生资源有限,因此,人们要更加关注可再生资源的开发和利用。从远古的钴木取火到今天核能的和平利用,人类发
Different forms of energy exist, their sources are also different. Energy is generally divided into two types: non-renewable energy and renewable energy. Non-renewable energy refers to those energy that can not be resumed within a short period of time once it is consumed, such as coal, oil and natural gas. Renewable energy, also known as renewable energy, such as wind, tidal, solar and water, these “inexhaustible energy.” As in the process of using the environment will not cause pollution, it is also known as clean energy. Because of the limited non-renewable resources on Earth, people should pay more attention to the development and utilization of renewable resources. From the ancient Cobalt fire to the peaceful use of nuclear energy today, human hair
