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.

Why it’s time the U.S. creat

Why it’s time the U.S. creates a national energy grid

If there is one thing almost every clean energy analyst agrees on, it’s that, when it comes to grids, bigger is better. Sharing energy over a wider geographic area improves efficiency, smooths out peaks and troughs in demands, reduces the use of duplicative backup sources, allows for the Read More...

Goodbye coal: England and Germ

Goodbye coal: England and Germany keep setting new EU clean energy records

The UK’s electrical grid has not burned any coal for about 1,000 hours so far this year. That figure for the whole of 2016 was 210. Last year it was 624. Germany is more dependent on coal. But the trend away from coal pollution is clear there too. So far, this year coal generated about 35.1 Read More...

A ‘flow battery’ powers a home when there’s no sun or wind

The quickly growing solar and wind energy capacity requires vast and cheap battery storage. Regular lithium-ion batteries cannot be scaled enough to provide the necessary capacity. Researchers are working on “flow batteries” that can soak up enough excess wind and solar power to fuel whole Read More...

Steep decline in price of sola

Steep decline in price of solar energy offsets Trump tariffs

The tariffs of the Trump administration are not stopping the advance of solar energy. A steep global decline in the price of solar panels in recent weeks is nearly offsetting the effect of the Trump administration's 30 percent tariff on imported panels, says the CEO of SunPower, a U.S. solar energy Read More...

The world’s largest sola

The world's largest solar farm opens in the Egyptian desert next year

Lack of sun has never been the problem for Egypt. However, the country gets more than 90 percent of its electricity from oil and natural gas. But that’s going to change. Next year, Egypt will open the world’s largest solar park. It’s a major step in a government strategy that by 2025 Egypt Read More...

These windows block the sun an

These windows block the sun and produce power at the same time

There are windows in buildings and card that shut out light to lower heating and cooling costs. There are also windows that feature a coating of see-through solar cells that produce electricity. But, so far, there are no windows that do both. But Chinese scientists have now developed a new material Read More...

Battery innovation: your coffe

Battery innovation: your coffee waste can power your phone

The lithium-ion batteries that power your phone, your laptop as well as electric vehicles, use natural and artificial graphite. Graphite—a kind of carbon—is not cheap. That’s why researchers in Taiwan were searching for a replacement substance. They started experimenting with another source Read More...

The story of the battery that can change everything for renewable energy

Bill Joy is a legendary computer scientist—a co-founder of Sun, a co-inventor of Java, and a visionary who was working on the Internet of Things two decades ago. Today, he’s the driving force behind a new battery technology that could revolutionize the renewable energy economy. The new battery Read More...
