In George Orwell's novel, 1984, a totalitarian regime now rules the homeland and operates by three slogans: 1) War is peace, 2) freedom is slavery and 3) ignorance is strength. In 1984 the term "Newspeak" refers to what is essentially a mandatory style guide for using the English language under that regime by substituting Newspeak formulations for common words and phrases so as to make public discourse conform to the ruling party's orthodoxy. (For a list Newspeak words and phrases, check here.)
Not surprisingly, failure to conform to this style in written and oral communications is considered a crime. In fact, to think thoughts contrary to those expressed in Newspeak terms is considered a "thoughtcrime" because it implies one's personal values are not in harmony with official party dogma. Even having a facial expression that appears to imply disagreement with that dogma is a "facecrime."
Every modern regime tries to regulate the language used by its citizens (or subjects, as the case may be). As I have written previously, "If you want to corrupt a people, corrupt the language." So, it's not particularly surprising that the U.S. Department of Energy (DOE), now controlled by an oil industry insider, has put out its own Newspeak-like manual in the form of an email to department employees which is focused on subtracting words and phrases according to Politico. In the email the DOE is doing to the vocabulary of its personnel what the Trump administration is doing to the government, namely, cutting it.
