谢谢你的解释。网上确实可见这个词，只是还没有现成的翻译。让Wenjer想出来一个。

Aha, Raffaella, I got the "finale (Pointe)." Let me think a little while to render a suitable expression for this invented term.

Origin of negawatt - While reading a Colorado Public Utilities Commission report, Amory Lovins found a typo "negawatt" (the report had meant "megawatt"). Lovins saw the typo as a way to describe a watt of electricity that wasn't created, due to energy efficiency.
A negawatt is a concept related to power and electrical generating capacity. A similar concept applies to energy, with potential consumers being rewarded for lowering consumption at any time, rather than just at peak times: this could then be labeled negajoules or negawatt-hours.

Tian is right. It must be "megajoule (兆焦耳)".

会不会是原文中有书写错误？科技用计量单位中有mega做词头的，表示兆或百万，但没见过nega。
