Waste like this should meet all of a UK grocery store's electrical needs (Photo: Shutterst...

It's an unfortunate fact that every day around the world, supermarkets throw out tons of food that has spoiled before it could be purchased. While it would be best if that spoilage could be avoided in the first place, British grocery chain Sainsbury's is taking what might be the next-best approach – it's about to start using that unsellable food to power one of its stores.  Read More

Belize has begun using drones to monitor its coastline for illegal fishing operations

Unsustainable fishing in Belize has placed growing pressure on local anglers and the country's celebrated coral reef systems. Decades of decline has led to the introduction of catch limits and even the European Union blacklisting seafood imports from Belize for a perceived lack of action against illegal fishing. In an effort to better regulate the industry, the Belize Fisheries Department has begun using drones to monitor coastal areas for unlicensed and unlawful activity.  Read More

Generating renewable electricity at home or commercial buildings is becoming increasingly viable. WindStream Technologies has installed what it says is the world's largest wind-solar hybrid array on an office roof in Kingston, Jamaica. The array is expected to generate over 106,000 kWh annually.  Read More

A group of British artists have conceptualized a giant solar harvesting floating duck as part of the 2014 Land Art Generator Initiative Copenhagen design competition. Dubbed Energy Duck, the giant structure has been designed not only to generate clean electricity for the local residents of Copenhagen, but to also provide a unique visitor center.  Read More

Illustration of the 'moth eye' solar cell (Illustration: Empa)

As nocturnal creatures, moths need to maximize how well they can see in the dark whilst remaining less visible to avoid predators. This ability to collect as much of the available light as possible and at the same time reflect as little as possible, has inspired Researchers at the Swiss Federal Laboratories for Materials Science and Technology (Empa) to design a new type of photoelectrochemical cell using relatively low cost materials.  Read More

The net-zero test home at the National Institute of Standards and Technology (NIST)

Braving a harsh winter with snow-covered solar panels, the Net-Zero Energy Residential Test Facility (NZERTF) in Washington DC has come up trumps in a year-long study of its energy harvesting capabilities. Located on campus at the National Institute of Standards and Technology (NIST), researchers used computer simulation to replicate the energy consumption of a family of four. At the end of its first 12 months, there was a large enough surplus to power an electric car for 1,440 miles (2,317 km).  Read More

Along with a timely hit of caffeine, takeaway coffee can deliver its fair share of environmental angst as the office trash can begins to brim with empty paper cups. But what if, instead of being carted off to landfill, these cups could be recycled up to seven times, much like newspapers and regular cardboard? According to UK-based inventor Martin Myerscough, a small difference in the way these cups are produced could significantly reduce the monumental waste generated by today's coffee-crazed society.  Read More

A number of parks in the Boston area will soon receive solar-powered smart benches, courtesy of Changing Environments, an MIT Media Lab spin-off company. Dubbed Soofa, the benches sport a solar panel, a pair of charging points for smartphones (or similar devices), and they monitor environmental data such as local air quality and noise pollution.  Read More

Rising atmospheric CO2 levels can generally be tackled in three ways: developing alternative energy sources with lower emissions; carbon capture and storage (CCS); and capturing carbon and repurposing it. Researchers at Princeton University are claiming to have developed a technique that ticks two of these three boxes by using solar power to convert CO2 into formic acid.  Read More

It was seven years ago that Ecosphere Technologies revealed its first iteration of a self-contained relief unit to provide power, water and shelter to disaster-struck areas. The company has since been busy refining the system's form and function and now announces the completion of what it says to be the world's largest deployable solar power generator. Capable of generating 15 kW of electricity, PowerCube is transported as a standard shipping container and can morph into a shelter, water treatment plant and communications base all with a push of a button.  Read More
