Turns out the Department of Energy is just as sinister as Stranger Things made them out to be. Writer Lachlan Markay of the Washington Free Beaconunearthed pages and pages of email correspondence from within the Department that gives some backing to the show putting the DoE in a, let's say, negative light.
After Netflix released Stranger Things in July, the series was discussed heavily within the Department. These emails between Department members ultimately led to a blogpost, published by Paul Lester of the Office of Public Affairs on Energy.gov. It said decisively "the show's portrayal of the Energy Department was a little less than accurate."
Markay submitted a FOIA request for these discussions. He found that department members believed the show portrayed them as "sinister (but awesome)" and wasn't always too far from the truth.
In one heavily (and scarily) redacted email between Department members, human experiments and military weapons testing are discussed. In other emails, Markay found mention of scientists who are "almost certainly are doing a fair amount of research on parallel universes."
