The values that will govern choices among future energy systems are unlikely to be the same as the values we embrace today. This paper discusses principles of rational choice for agents expecting future value shifts. How do we ought to reason if we believe that some values are likely to change in the future? Are future values more, equally, or less important than present ones? To answer this question, I propose and discuss the Expected Center of Gravity Principle, which articulates what I believe to be a reasonable compromise between present and future values.

价值变化、能源系统和理性选择：预期重心原则

将指导未来能源系统选择的价值观不太可能与我们今天所接受的价值观相同。本文讨论了预期未来价值转移的代理人的理性选择原则。如果我们相信某些价值观在未来可能会发生变化，我们应该如何推理？未来的价值比现在的价值更重要、同等重要还是更不重要？为了回答这个问题，我提出并讨论了预期重心原则，它阐明了我认为现在和未来价值之间的合理折衷。
