Fusion energy still has a long way to go.

Elon Musk: fusion will probably be more expensive than wind, solar

Game of Renewable Thrones

In a recent tweet, Elon Musk argued that fusion energy will probably be more expensive than wind and solar. Experts are divided.

Elon Musk: Fusion Will Probably Be More Expensive Than Wind, Solar

Elon Musk says he's impressed by the research — with one major catch.

The team is expecting to generate ten times the heat than what has to be put in.

Scientists start construction of world's largest fusion reactor

30 Years Away

Engineers have begun construction of the world's largest nuclear fusion project today in southern France, with operations planned to begin in late 2025.

Scientists Start Construction of World’s Largest Fusion Reactor

"Enabling the exclusive use of clean energy will be a miracle for our planet."

At the very least, it's a fascinating example of squeezing interesting research out of dated equipment.

Scientists just got amazing results from an old fusion reactor

Earth & Energy

A team of scientists found they achieved high pressure plasma and energy — in theory enough to achieve fusion power — at an old fusion reactor in San Diego.

We could be seeing a fusion power plant go online in just 15 years.

MIT is taking on fusion power. Could this be the time it actually works?

Hard Science

An international collaboration, including researchers from MIT, is harnessing a new type of superconducting magnet to herald a fusion-powered future.

MIT Is Taking on Fusion Power. Could This Be the Time It Actually Works?

"We think we have the science, speed and scale to put carbon-free fusion power on the grid in 15 years."

Nuclear fusion can produce essentially limitless supplies of power without creating excess radioactive waste.

The long wait for fusion power may be coming to an end

Fusion power has the potential to provide limitless energy with little waste. There are many challenges still ahead, but we may have less time to wait.

The Long Wait for Fusion Power May Be Coming to an End

"We know the science is absolutely real because we can see it happening in the sun every day."

An unlimited source of clean energy is on the horizon, but just how far away is the horizon?

Watch: How Far Away is Fusion Power?

The small, spherical Tokamak ST40 reactor is on track to reach its next goal of hitting the 15,000,000 °C (27,000,000 °F) mark this autumn.

Mini Reactors Could Make Affordable Fusion Power a Reality by 2030

Limitless, clean energy is possible.

Tokamak Energy's fusion reactor has achieved first plasma and is on track to produce temperatures of 100 million degrees Celsius by 2018.

A “World First” Fusion Reactor Just Created Its First Plasma

“This will allow fusion power to be achieved in years, not decades.”

Cleaner energy sources are becoming cheaper too.
