Transitioning to a world powered by renewable energy is key to tackling climate change. Here you can find the latest good news related to our clean energy transition, covering wind, solar, green hydrogen, hydropower, and more.

This bio-rover is essentially driven by a marimo ball

What is marimo? Marimo is arguably one of nature’s most bizarre creations. Commonly known as algae balls or moss balls, these algae bundles are typically found on lake floors in Japan and Northern Europe. Their fuzzy spherical shape is the result of gentle currents rolling the algae over and Read More...

Levitating ice leads to deeper understanding of energy

Believe it or not, scientists have been levitating water since the 18th century. The Leidenfrost effect was first described in 1751 by a German doctor and theologian, who named the phenomenon after himself. Using a high temperature plate of 150˚C, he observed that a water droplet could be made to Read More...

This discarded 1990s window design could help fight climate change

According to the United States Department of Energy, buildings use about 76 percent of electricity in the US and are responsible for about 40 percent of all direct and associated greenhouse gas (GHG) emissions in the country. This means that reducing energy consumption from buildings is an Read More...

South Australia ran on 100 percent renewable energy for almost a week

The last week of 2021 has been an exceptional one for South Australia. The state set an impressive renewable energy record, supplying an average of just over 100 percent of its electricity demand with solar and wind for a period of almost one week. The unprecedented clean energy run was recorded Read More...

Liquid metal turns CO2 emissions into solid carbon at the source

Capturing carbon dioxide before it reaches the atmosphere is a key part of our global strategy to combat climate change. In an effort to find ways that could help us do that efficiently, scientists at RMIT have developed a method that quickly converts carbon dioxide into solid carbon, which can Read More...

This solar panel covered building reflects Taiwan’s green energy transition

Most projects designed by the Dutch architecture firm MVRDV tend to leave a lasting impression on whoever lays their eyes on them. The company's upcoming project, Sun Rock, is no exception. Designed for Taiwan’s government-owned power company Taipower, the project takes the form of a building Read More...

Rapidly retrofitting old buildings is key for climate goals - Here's how to do it

Buildings account for about 40 percent of annual global carbon emissions. In order to meet our climate goals, every building on the planet will have to be net-zero by 2050. But since most of the current buildings will still exist then, a massive number of homes will have to undergo retrofits in Read More...

Windows giant Anderson gives solar window integration a $30M boost

Here at The Optimist Daily, we love sharing stories about the exciting advancements that we are making in terms of discovering and fashioning creative ways that we can harvest clean, green, and renewable energy. One of the threads of renewable energy we’ve been following closely is solar Read More...

‘Strange metal’ may be the future for a more energy efficient world

Strange metal behavior was first noticed around 30 years ago. These materials are composed of copper-oxides and carry the properties of being high-temperature superconductors. This means they can transfer electricity very efficiently, withstanding much higher temperatures with less energy loss than Read More...

China’s “artificial sun” fusion reactor breaks yet another record

The Chinese Academy of Sciences has exciting news about its fusion reactor that it recently shared in a release. The Experimental Advanced Superconducting Tokamak (EAST) fusion reactor successfully sustained a plasma temperature of 120 million degrees Celsius for 1,056 seconds, effectively Read More...
