net energy gain
- 净能量增益：净能量增益是能源经济学中使用的概念，指的是从能源收获中消耗的能量与获得的能量之间的差异。净能量增益可以用焦耳表示，与能源收获过程可能产生的净财务收益不同，因为不同能源（例如天然气、煤炭等）的定价可能不同，但所提供的能量量相同。

Net energy gain
- abstract: Net Energy Gain (NEG) is a concept used in energy economics that refers to the difference between the energy expended to harvest an energy source and the amount of energy gained from that harvest. The net energy gain, which can be expressed in joules, differs from the net financial gain that may result from the energy harvesting process, in that various sources of energy (e.
