However it may be husbanded, however stretched out, the energy once expended is gone and cannot be restored.

无论怎样节约，无论怎样利用，用掉的能量就是用掉了，不能回复。

Man said, "Carefully husbanded, as directed by the Cosmic AC, the energy that is even yet left in all the Universe will last for billions of years. ""

人说：“如果在太宇埃克的管理之下小心地节约能源，整个宇宙所剩下的能量还能维持几十亿年。”
