Energy
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.
Ocean energy is on the horizon following successful test on floating turbine
You may not have heard much about ocean energy before, but the European Commission believes it could supply 10 percent of the EU’s power by 2050. That looks ever more likely after a single floating turbine off the coast of Scotland generated 3-gigawatt hours of renewable electricity from the Read More...
This Greek island will be first in the Mediterranean powered only by renewables
The small Greek island of Tilos has long had a costly power system that gets its energy from a diesel power station 42 miles away. Now Tilos has constructed a new system powered entirely by wind and solar, making it the first island in the Mediterranean to power itself entirely with renewable Read More...
A startup is stacking concrete blocks with cranes in order to store energy
Electrical grids only function when electricity is being generated in the same amounts as it is consumed. About 96 percent of the world’s energy-storage capacity comes in the form of one technology: pumped hydro, which uses water and dams to generate energy on demand. A startup from Switzerland Read More...
Renewables are set to leapfrog natural gas faster than anyone predicted
Natural gas was meant to be the bridge that helps the energy sector shift from coal to renewables. But now, just years into gas’s rise to power, renewables are already getting set to cross the bridge and become the dominant source of energy. While the price of natural gas is inherently volatile, Read More...
The lithium-metal battery may solve our energy storage woes
While lithium-ion batteries are currently our most effective batteries, they’re still not powerful enough to full displace gasoline-powered cars or cheap enough to solve the big energy-storage problem of solar and wind power. A Massachusetts-based startup believes they have the solution: a Read More...
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...
This utility helps you cut your energy and carbon usages in real time
Energy conservation can make the biggest contribution to prevent further global warming. Technology can help with that. This New Zealand utility company helps customers in real-time to change their energy use. Knowledge is Read More...
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...
Tesla solar roof owner explains costs and savings (video)
In this video, one of the first owners of a Tesla Solar Roof talks about his very positive 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...
