I don't always have the surplus energy for this.

我并不总是有多余的精力来做这件事。

Surplus energy is sold to neighboring towns, and profits are reinvested back into the community.

剩余的能源被卖给邻近的城镇，利润再投资回社区。

The government buys surplus energy produced from the villagers if they do not use all of the amount that has been given to the household.

如果村民没有用完所有提供给家庭的能源，政府就会从村民那里购买剩余的能源。

But it was part of my boredom — I remember — that I was feeling so uncommonly well, and didn't know how on earth to work off my surplus energy.

但这是我无聊的一部分——我记得——我感觉非常好，不知道到底该如何消耗我多余的能量。

When I observed that for the first time, I suddenly realized that by flapping their wings they were releasing surplus energy, thus preventing it from becoming trapped in their body and turning into negativity.

当我第一次观察到这一点时，我突然意识到， 通过拍打它们的翅膀， 它们正在释放多余的能量， 从而防止它被困在它们的身体里， 变成消极的。
