U.S. energy consumption plummeted to its lowest level in more than 30 years this spring as the nation’s economy largely shut down because of the coronavirus, federal officials reported Wednesday.

Those trends are expected to turn around as commercial activity resumes, but an annual decline in U.S. and global greenhouse gas emissions is expected and some energy companies already have fallen into bankruptcy.
