From the real science behind the Upside Down in Netflix's "Stranger Things" to the mysterious death of a U.S. president, Direct Current is pulling back the curtain on some of our deepest, darkest #EnergySecrets.

SHORT CIRCUIT | Energy @ 40

Energy is 40 and we're celebrating with a look back at four decades of #ScienceForThePeople. We talk to the Department's longest-serving employee (53 years!), revisit the agency's origins, and look to the future with the help of our official historians.

S2 E6: A Shot in the Dark

Earth, the cosmos, everything we can see with our eyes and our instruments is made up of normal matter. But all that doesn’t add up to a whole lot. It's just 15% of the mass of the universe. The rest is an unknown, invisible… something…

SHORT CIRCUIT | Solar, Meet Eclipse

Solar power is booming in the U.S. So what happens when the sun disappears during the total solar eclipse on August 21, 2017? We talk to the energy experts.

S2 E5: Hyper Drive Time

And now, for something completely different… Take a drive with Direct Current as we mash up three slightly off-kilter energy stories. It might get weird, but it won’t be boring. It’s Hyper Drive Time!
