Renewable Energy

Using electrical storms as a jumping off point, scientists at Israel’s Tel Aviv University believe they may have uncovered a new source of renewable energy, generating a small voltage using only water and metal.

Wind turbine towers have become a familiar sight in many parts of the world, but if Ampyx Power has its way, they could be replaced with fleets of tethered drones that harness the energy of high-altitude winds to run generators on the ground.

Researchers at the University of Southern California looking to crack the renewable energy storage problem have developed a new version of a redox flow battery from inexpensive and readily-available materials.

The Sun is a great source of energy, but of course those rays can be damaging as well. Engineers in Korea have now developed a new way to make perovskite solar cells to protect them from the elements without reducing their efficiency.

Stacking perovskite solar cells on top of silicon ones is one way to increase the amount of sunlight harnessed. Now researchers at Australian National University (ANU) have broken a new efficiency record for these tandem solar cells.

The waters surrounding the UK have long played home to some of the world's most ambitious renewable energy projects, and they are set to welcome another with construction now underway at Dogger Bank, the world's largest off-shore wind farm to be.

The biggest battery in the world is set to soon grow even bigger. The Hornsdale Power Reserve in South Australia, built by Tesla and managed by renewable energy company Neoen, will be expanded by an extra 50 percent early next year.

As reported by Tokyo-based newspaper Nikkei Asian Review, plans are afoot to transform Fukushima into a renewable energy hub, with 21 wind and solar plants to be built and the power to be fed into the national grid for use in the country’s capital.

A new report declaring a climate emergency has been signed by thousands of scientists. But it remains hopeful, outlining six steps we can take to mitigate the worst effects of climate change – provided we act sooner rather than later.

Holland’s Nuna solar car appeared all set to claim another crown at this year’s World Solar Challenge, until disaster struck within a couple of hundred miles of the finish line, clearing the way for Belgium’s Agoria Solar Team to take the title.

Following a second grid-connected project at Jaffa Port in Israel, Eco Wave Power is looking to get more from its energy harvesters by adding solar.

A new prototype device works like a kind of reverse solar panel, harvesting energy from the cold night sky to passively power an LED.
