And it quickly turns that solar energy into hydrogen.

Much cooler than your garden-variety solar panels.

With calm seas and mild winds, some equatorial regions are prime candidates for massive floating solar arrays.

Generating electricity from the sun is getting cheaper...but is it right for your home?

He's had crazier ideas.

It's like using a magnifying glass to start a fire. Only much bigger.

This megastructure for gathering solar energy would fill any conceivable future energy desires. But can it ever truly exist?

Renewable options are slim on the Red Planet. So why not get weird?

It's too noisy, falling apart, and doesn't even collect enough solar energy.

No, they aren't magic. Here's how solar panels *actually* convert light into energy.

It uses silent electric propulsion to achieve virtually unlimited range.

See why people are stocking up on solar during the pandemic.

And they also save more money than single, stationary panels.

It can store 8 megawatt hours of thermal energy when full, and discharge about 200 kilowatts of power.

Featuring the largest geothermal installation in North America, the campus buildings have solar roofs with a unique textured coating that traps solar rays.

And it knows exactly when it’s going to happen.

Go camping—and save money—with clean, quiet, reliable solar energy.

Tough break for fossil fuels.

Why not return the favor?

We might have had it wrong this whole time.

Easy, actionable ways to reduce your resource consumption.

Insurgents are known to attack fuel tankers headed toward bases in conflict zones. This could be the solution.

It's a free fusion reactor in the sky. Now how do we catch it?

The reactor is ready for the big time.

For the first time since WWII, a renewable energy source has outpaced fossil fuels.

One plant could collect 100 MW of solar radiative power to produce about nine million gallons of kerosene per year.

Power your home, save money, and help the environment.

The megastructure could produce 1,000 times more energy than the Large Hadron Collider, allowing scientists to “rewind” the clock and study the origins of the cosmos.

This country could do it and supply energy to 136,000 homes per year.

The first one saved Australia tens of millions of dollars. The next one is bigger in every way.

Never underestimate the power of a pile of pebbles.

Wood and bacteria will help, too.

Using kinetic energy, it's got the potential to be more efficient than solar panels.

And it's only getting bigger.

This is some real sci-fi stuff.

It's a solar power breakthrough.

These scientists did it in under a half hour.

You might not see it again for years.

It's called "optically coupling with deep space."

Jessica Meir and Christina Koch conducted a seven hour and seventeen minute spacewalk.
