Emission-free hydrogen could, one day, entirely replace fossil fuels - and a start up believes it has the key ingredient to make it work.

Most solar cells are currently silicon based; however, their efficiency is limited. This has prompted researchers to examine new materials.

power beaming could offer the world huge potential to tap into renewable energy sources and contribute to carbon-neutrality by 2050.

Can we survive three minutes without air or three days without water? How about without batteries? Imagine not having a battery for 3 hours.

Physicists successfully developed a circuit capable of capturing graphene's thermal motion and converting it into an electrical current.

Novel engine converts heat to electricity with over 40 percent efficiency — a performance better than that of traditional steam turbines.

Radioactive diamond batteries were immediately acclaimed because they promised a new, cost-effective way of recycling nuclear waste.

Solar panels often get a bad rap for spoiling the appearance of homes and businesses. Yet, this may be about to change.

Enapter says its electrolyser uses about 2.4 litres of water to generate enough hydrogen for a couple's home for several days.

A teen genius at a U.S. middle school has built a working, tiny nuclear fusion reactor—and made it into Guinness World Records.

Researchers develop a scalable fabrication technique to produce ultrathin, lightweight solar cells that can be added to any surface.

A new type of solar energy harvesting system breaks the efficiency record of all existing technologies collecting solar power 24/7.

Health benefits of using wind energy instead of fossil fuels could quadruple if the most polluting power plants are selected to dial down.

Their new demonstrations show that it converts heat to electricity with over 40 percent efficiency a performance better than steam turbines.

Solar panels often get a bad rap for spoiling the appearance of homes and businesses. Yet, this may be about to change.

Pacemakers and other medical devices, as well as long-distance drones and remote sensors, would require fewer battery replacements.

How can we remove carbon dioxide, a greenhouse gas, from fossil-fuel power plant exhaust before it ever reaches the atmosphere?

The great inventor Thomas Edison once said, “So long as the sun shines, man will be able to develop power in abundance."
