Ten months after Hurricane Maria, Adjuntas still loses power any time a heavy rain or wind pounds the rickety power lines feeding this town high in the central mountains of Puerto Rico.

That leaves its 20,000 people once again in the dark, without light, fresh water or air conditioning—except for a handful of homes and businesses glowing in the night thanks to .

The people of Adjuntas call those places “cucubanos,” an indigenous Puerto Rican firefly. They’re part of a small but growing movement to provide the U.S. territory with sustainable, renewable energy independent of the decrepit grid.

You might never have heard of expanded polystyrene, but you’ve definitely used it. It’s the lightweight white foam used for everything from packing peanuts to holding boxes of veggies at the supermarket.

Expanded polystyrene (EPS) is versatile, waterproof, and surprisingly strong. Unfortunately, it’s also a nightmare to dispose of. It fragments easily into many small, light pieces which can be easily carried away by the wind, and is difficult to process.

Australia exports some EPS to be recycled overseas, but we have less than one collection point per state. All of this means that The NSW Evironmental Protection Agency estimates that some 12,000 tonnes of EPS is sent to landfill every year. According to the Australian Plastics Recycling survey, about 14% of EPS is recovered for recycling. Most of that is exported – only around 1.6% of all the EPS used in Australia is recycled here.

A fashion collection made from the remains of grapes from the wine industry and plastic made from chicken feathers are two new twists on the practice of making new products from waste, and a growing demand for sustainability from consumers mean there could be a ready market for this type of innovation.

Food waste isn’t just the result of groceries that have gone off or uneaten meals. As food is processed for consumption, huge amounts of waste are generated. The European poultry industry, for example, generated about 3.1 million tons of discarded feathers in 2014. And during , around 25% of the weight of grapes, such as the skins and seeds, are wasted.

These byproducts could soon be given a second life, as scientists work out how to transform them into new .

Oak Ridge National Laboratory scientists have developed a crucial component for a new kind of low-cost stationary battery system utilizing common materials and designed for grid-scale electricity storage.

Large, economical electricity storage systems can benefit the nation’s grid in numerous ways: balancing loads between peak and off-peak demand times; supplying energy during outages; storing electricity from fluctuating sources like wind and solar power; and accommodating extreme fast charging of electric vehicles.

The grid chiefly relies on hydropower facilities for , although stationary systems using lithium-ion batteries are increasing. However, lithium is expensive and mostly sourced from countries outside the United States.

Agriculture uses 70 percent of the water in the world, and this appears to be an upward trend regarding water needs. As the demand in other industry sectors is also increasing, and the effects of climate change exacerbate water shortages, water saving measures have become an unavoidable challenge for maintaining the sector and preserving life.

Agronomy researcher Rafael González has developed a model to predict in advance the that users will need each day. This tool came about from a drive to ally with water resource sustainability.

The model applies artificial intelligence techniques including fuzzy logic, a system used to explain the behavior of decision making. It also mixes variables that are easier to measure, like agroclimatic ones or the size of the plot of land to be watered, with other more complicated variables, like traditional methods in the area and holidays during watering season.

UNSW solar energy researcher and Scientia Fellow Dr. Xiaojing Hao and her team have achieved two energy efficiency world records for the solar cell material of the future, sulfide kesterite.

Dr. Hao and her team broke the 10 per cent barrier for not only sulfide kesterite but also for a standard sized kesterite solar cell, whether pure sulfide material or incorporating less-desirable selenium.

The result, which is published in a paper in Nature Energy today, is the fourth consecutive efficiency record achieved by the group led by Dr. Hao in two years.

The engineering firm Munro & Associates made waves recently when it tore the new Tesla Model 3 apart both literally and figuratively. The company dismantles and studies cars and other products, and CEO Sandy Munro was very vocal about his feelings regarding Tesla’s newest electric vehicle. He said the build quality was like a Kia from the 90s. Now, the company has completed its analysis. While Munro’s opinion on the fit and finish hasn’t changed, he has expressed downright shock that the Model 3 is highly profitable for Tesla.

The initial Munro & Associates analysis of the Model 3 called out issues like clunky door handles and windows that bounce around inside the door panels. The exterior panels of the Model 3 also drew Munro’s ire. The gaps are substantially larger than the more expensive Teslas — even conventional cars that cost thousands less look more polished on the outside, according to Munro.

To say Munro & Associates was skeptical of the Model 3 early on would be an understatement. Now, Sandy Munro says he’s “eating crow,” but not because the Model 3 has better polish than he initially thought. The company has determined that it’s very profitable for Tesla. It’s probably the most profitable electric vehicle on the road right now.

We’ve had autonomous cars, autonomous trucks, and autonomous buses, and now Osaka-based diesel engine manufacturer Yanmar is introducing a new line of robotic tractors. On October 1, 2018, the company is releasing its 2-series tractors equipped with the Smartpilot autonomous operating system and Information and Communications Technology (ICT) that allow them to operate in autonomous and semi-autonomous modes.

From liquid laundry detergent packaged in cardboard to compostable plastic cups, consumer products these days are increasingly touting their sustainable and renewable origins.

Now researchers at Georgia Institute of Technology have created a material derived from crab shells and tree fibers that has the potential to replace the flexible used to keep food fresh.

The new material, which is described July 23 in the journal ACS Sustainable Chemistry and Engineering, is made by spraying multiple layers of chitin from crab shells and cellulose from trees to form a flexible film similar to plastic packaging film.
