Australia faces at least another year of policy uncertainty and stagnation in the renewables sector, Brazil has attracted a huge amount of interest from the developers of wind farms and solar farms for a government auction in November.

According to PV Magazine, 313 MW was added in July. This year alone 2,110 MW of new solar capacity have gone up in the European country.

New York State’s Governor Cuomo has launched a U$1 billion Green Bank initiative to mobilize private sector financing for clean energy projects, which will help generate jobs and boost the state’s economy.

Solar panels, when mounted on a building roof, not only generate electricity, but they also create a cooling effect, according to researchers from University of California, San Diego.

The public authorities in Japan are putting all their efforts into establishing a new industry based on floating offshore wind turbines.

The clock may tick a little slower on the remote, windswept German island of Pellworm, but when it comes to renewable energy, it has long been ahead of its time.

Americans are increasingly installing wind turbines near their homes, farms and businesses to generate their own energy, concludes a new report released today.

Australian soils are losing about 1.6 million tonnes of carbon per year from wind erosion and dust storms affecting agricultural productivity, our economy and carbon accounts, according to new research.

Modern water purification methods exist that can easily get rid of water contaminants, even salt and bacteria, but some organic toxins and toxic metals, such as arsenic and hexavalent chromium need special processing to be removed.

Scientists at Heliotrope Technologies, in conjunction with Lawrence Berkeley National Laboratory, have developed an inexpensive, energy-efficient glass composite.

Scientists believe it’s still possible to reduce CO2 emissions by a whopping 50% globally by 2050, but only if countries take drastic measures – like the ones taken by France.

Appearing at IFA, Panasonic has unveiled a brand new refrigerator which the company states is the first-ever A+++rated two-door refrigerator – making it the most energy-efficient two-door fridge, worldwide.
