2017-04-30，《纽约时报》在标题"How the Left Learned to Hate Like the Right" (by MICHELLE GOLDBERG)"之下的引文：
"Liberals are discovering what conservatives have known for years: Negative energy is a powerful force."

其实，"negative energy"是一物理概念，英文维基百科有此条目。

另外，英文里也有类似于中国“正能量”(positive energy)的用法。比如，Google "positive energy"，可见"How to Radiate Positive Energy - Spiritual Energy - Oprah.com", "A little science on positive energy | Psychology Today", "3 Ways to Transform Anxiety into Positive Energy - Tiny Buddha"，等等。
