能源危机不但现在在在,在过去也是一直在在的!并且未来的危机更严重!
分析如下:所谓能源危机,是指可供我们人类利用的能源的不充分,而不是能源本身的不足。
具体有:1、能源转化的方向性。并不是所有的能源都能够被人类利用,比如内能,其它能的形式转化为内能比较容易,而将内能转化为其它形式的能源,就很难办得到。
2、能源分布的不均性。可以说在地球上几乎全部的能源都来源于太阳,但是由太阳能转化成的各种能量形式在地球上的分布并不均匀,如在沙漠地带,太阳能充足,但却无人居住。
3、日益增加的人口导致能量分配不足。 Now the energy crisis not only in the past also has been in! Crisis and the future of the more serious!
As follows: the so-called energy crisis, is available for human use of our energy is not sufficient, rather than its own energy shortage.
Specific: 1, the direction of energy conversion. Not all human energy can be used, for example, can other forms of energy can be transformed into the relatively easy, and to be able to translate into other forms of energy, be very difficult.
2, the uneven distribution of energy. It can be said that almost all of the earth's energy is derived from the sun, but from the solar energy into the various forms on Earth is not evenly distributed, as in the desert, solar adequate, but uninhabited.
3, the increasing population led to an insufficient allocation of energy.
