A massive nuclear fusion experiment just hit a major milestone, potentially putting us a little closer to a future of limitless clean energy.

Around the world, biofuels, so-called green energy sources, are waving major red flags.

For well over a century, engineers have proposed harnessing the ocean’s tides for energy. But the idea hasn’t seemed to register in many places.

Ironically, the company did so using technology perfected by the oil industry.

Decades ago, a disaster left three million acres of land uninhabitable and killed between 85,600 and 240,000 people. Chernobyl? No. Banqiao dam in China.

Explore data on electric car sales and stocks worldwide.

Australia’s AAPowerLink boasts three global superlatives: largest solar farm, largest battery, and longest power cable.

The race to find dark matter could grow more complex with high-energy neutrino interference.

The term “zero-point energy” has at least two meanings, one that is innocuous and one that is a great deal sexier (and scammier).

Experiments on suborbital rockets are revealing how to make a better iron furnace.

From a hot, dense, uniform state in its earliest moments, our entire known Universe arose. These unavoidable steps made it all possible.

Two parts of our Universe that seem to be unavoidable are dark matter and dark energy. Could they really be two aspects of the same thing?

A new hypothesis accuses the simple sugar of wrecking energy metabolism.

When leaders embrace positive personal energy, everyone feels the benefits — in trust, innovation and creativity.

More than any other equation in physics, E = mc² is recognizable and profound. But what do we actually learn about reality from it?

Dark energy is one of the biggest mysteries in all the Universe. Is there any way to avoid “having to live with it?”

Figuring out the answer involved a prism, a pail of water, and a 50 year effort by the most famous father-son astronomer duo ever.

The galactic center is home to the most powerful engine in the Milky Way: a supermassive black hole. How does its energy ultimately escape?

A recent paper in the journal Physical Review Letters claims to prove that a “kugelblitz” is not possible.

It’s possible to remove all forms of matter, radiation, and curvature from space. When you do, dark energy still remains. Is this mandatory?

Electric vehicle sales are rising but public charging in cities is still lacking.

The material is both stronger and lighter than those used to make conventional power plant turbines.

The standard picture of our Universe is that it’s dominated by dark matter and dark energy. But this alternative is also worth considering.

The futuristic weapon could be ready for the battlefield in 5 years.

“A person’s mass is made not of ‘stuff’ in the way we normally think about it, but rather our mass is made of energy.”

Einstein’s most famous equation is E = mc², which describes the rest mass energy inherent to particles. But motion matters for energy, too.

Apart from the energy needed to flip the switch, no other energy is needed to transmit the information.

Humans, when we consider space travel, recognize the need for gravity. Without our planet, is artificial or antigravity even possible?

In all the Universe, only a few particles are eternally stable. The photon, the quantum of light, has an infinite lifetime. Or does it?

The largest particle accelerator and collider ever built is the Large Hadron Collider at CERN. Why not go much, much bigger?
