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.

How to win Google’s Million-

How to win Google’s Million-dollar electricity challenge

Google has announced the Little Box challenge: a contest that will pay you $1 million if you build a 95% energy efficient power inverter, no bigger than a tablet, that’s capable of powering a house. A power inverter is a box that turns direct current that flows from solar panels or batteries, to Read More...

A company that greens your building with no upfront costs

Buildings are one of the largest consumers of energy, and the worst of the worst are commercial offices. Unnecessary heating and cooling of conference rooms and spare offices eat up large amounts of energy and contribute to the overall problem of greenhouse gas emissions. Enlighted is a new Read More...

Innovation makes biofuel compe

Innovation makes biofuel competitive energy source

Biofuel crops can reduce or offset greenhouse gas emissions by directly removing carbon dioxide from the air as they grow and store it in crop biomass and soil. Fuels from bioenergy crops are thus considered emission-neutral when burnt. The challenge is to get a good energy yield from the crops. Read More...

Perovskite: paint that turns any surface into a solar panel

The sun shines everywhere. So how can we easily capture the energy the rays of sun bring wherever they hit the earth? The answer is perovskite. What? Perovskite is a mineral composed of calcium titanium oxide that scientists at the University of Sheffield have now turned into a “spray on solar Read More...

Solar sponge turns suns energy

Solar sponge turns suns energy into steam

A sponge designed at Massachusetts Institute of Technology converts water into steam by using the sun’s rays. The sponge is made up of a layer of graphite flakes on top and porous carbon foam underneath that acts as an insulator. The sponge floats on top of water and when sun hits the graphite a Read More...

Wind cheaper than oil, coal or natural gas in Denmark in 2016

Investments in wind power that Denmark started making over 40 years ago are now starting to pay dividends—and large ones at that. Analysts at the Danish Energy Association predict that by 2016 wind power will overtake coal and natural gas as the country’s cheapest source of energy. Two new Read More...

California could be powered by 100% clean energy by 2050

There are plenty ambitious renewable energy projects and studies. But this new one by Stanford University is particularly interesting as it's about the 8th largest economy in the world—California—becoming totally clean energy based 35 years from now. The study, published in Energy, concludes Read More...

Self-cooling solar cells incre

Self-cooling solar cells increase efficiency and lifespan

The biggest hurdle solar cells have to overcome is overheating because converting sunrays to electricity—unsurprisingly—is a very hot process. When solar panels get hot their efficiency dramatically decreases. Engineers from Stanford University have found a solution to this problem by adding a Read More...

New GE startup shows that the time of clean energy fuel cells has come

Fuel cells where invented over a century ago. But apart from the use in space shuttles and space labs, the clean energy technology still awaits a real breakthrough. But the age of the fuel cell may finally be dawning. On Tuesday General Electric launched a startup to bring clean, reliable, Read More...

American cars are finally becoming more fuel-efficient

American cars guzzle some 9 million barrels of oil per day. And the American car industry has been notoriously late with implementing fuel-efficiency standards. But faced with a US EPA and Department of Transportation mandate that cars must have an average fuel–efficiency of 54.5 MPG by 2025 the Read More...
