How small farmers could be leading the way towards sustainable agriculture

Agriculture is a leading cause of climate change, but it is also undeniably affected by it. Farming must therefore change in order to keep up with global demands, while reducing its environmental impact. Without these necessary changes, it’s estimated that by 2030, the impacts of climate change will be even worse, causing yields to decline

Artificial leaves convert carbon with 10x efficiency of nature

Artificial leaves mimic photosynthesis -- the process whereby plants use water and carbon dioxide from the air to produce carbohydrates using energy from the sun. But even state-of-the-art artificial leaves, which hold promise in reducing carbon dioxide from the atmosphere, only work in the laboratory because they use pure, pressurized carbon dioxide from tanks. But

Collaboration sparks sustainable electronics manufacturing breakthrough

Simon Fraser University and Swiss researchers are developing an eco-friendly, 3D printable solution for producing wireless Internet-of-Things (IoT) sensors that can be used and disposed of without contaminating the environment. Their research has been published as the cover story in the February issue of the journal Advanced Electronic Materials. Additionally, 3D printing can give flexibility to add or embed functions onto

100% Renewable Energy Across Europe Is More Cost-Effective

No pun intended here, but in this climate of scientific denial, it’s time to listen to independent research again! Energy Watch Group and LUT University combined their resources to work on a new research that proves the feasibility of a European energy transition to 100% renewable sources. The study has simulated a full energy transition

Manchester scientists have clean energy breakthrough

Scientists have used a Nobel-prize winning Chemistry technique on a mixture of metals to potentially reduce the cost of fuel cells used in electric cars and reduce harmful emissions from conventional vehicles. The researchers have translated a biological technique, which won the 2017 Nobel Chemistry Prize, to reveal atomic scale chemistry in metal nanoparticles. These

New technology to protect drinking water from Lake Erie algal toxins

Before the 2014 Toledo Water Crisis left half a million residents without safe drinking water for three days, Dr. Jason Huntley's research at The University of Toledo focused on bacteria that cause pneumonia. After the harmful algal bloom prompted the city of Toledo's "Do Not Drink" advisory, the microbiologist expanded his research projects to target

How sustainable are bioplastics?

At face value, taxing consumption of materials derived from petrochemicals and subsidizing production of bioplastics both sound like they’d encourage sustainable consumption. But applying these policies to meet a hypothetical 5% target for bioplastics use reveals a different story, according to scientists in Germany. Today, bioplastics have a market share of around 1%, but as

Lettuce show you how to restore oil-soaked soil

Rice University engineers have figured out how soil contaminated by heavy oil can not only be cleaned but made fertile again. How do they know it works? They grew lettuce. Rice engineers Kyriacos Zygourakis and Pedro Alvarez and their colleagues have fine-tuned their method to remove petroleum contaminants from soil through the age-old process of

Heart’s energy to power life-saving devices

The heart's motion is so powerful that it can recharge devices that save our lives, according to new research from Dartmouth College. Using a dime-sized invention developed by engineers at the Thayer School of Engineering at Dartmouth, the kinetic energy of the heart can be converted into electricity to power a wide-range of implantable devices,

Renewable electricity accounted for 32pc of Ireland’s energy

Ireland is on its way to meeting the 2020 goal of having 40pc of electricity coming from renewable sources. According to new analysis from EirGrid, 32pc of electricity demand in Ireland during 2018 was met by renewable electricity sources; in Northern Ireland, the figure was even higher at 36pc. The figures in 2017 were 30pc

UMN collaborates with Puerto Rico to explore sustainable energy

After Hurricane Maria hit Puerto Rico in 2017, many went without electricity for months. Now, students and faculty from the University of Minnesota are working with partners on the island to explore different energy platforms that could withstand future natural disasters. University students went to Puerto Rico this month through the University’s Global Convergence Lab.

Overcoming the colonial development model of resource extraction

The end of the last commodity boom from 2000-2014 and recent swings in world oil prices have once again brought to the fore one of the most important binding constraints to long-term growth and economic development in Africa—the lingering effects of colonialism on Africa’s patterns of trade and the dynamics of world markets. Several decades

An air conditioner powered by outer space

A team of Stanford University electrical engineers has developed a new device that could cool buildings while simultaneously generating electricity. If the prototype proves scalable, the technology could represent another possible pathway for reducing the footprint of the built environment, which accounts for almost 40 percent (PDF) of the carbon emissions of the United States alone.

Editors’ Picks 2018: Sustainability and the Environment

The year 2018 wasn’t an easy one for the planet. Throughout the year we worried about how soon we may have to say good-bye to the Mediterranean region, what mysterious blight is killing European trees and whether a freshly calved Manhattan-sized iceberg would flood Manhattan. But there was also good news. We learned that our

A landscape unseen in over 40,000 years

Glacial retreat in the Canadian Arctic has uncovered landscapes that haven't been ice-free in more than 40,000 years and the region may be experiencing its warmest century in 115,000 years, new University of Colorado Boulder research finds. The study, published today in the journal Nature Communications, uses radiocarbon dating to determine the ages of plants

Major northeastern U.S. snowstorms expected to continue with climate change

Even though climate change is expected to reduce the total amount of U.S. snowfall this century, it's unlikely to significantly rein in the most powerful nor'easters that pummel the East Coast, new research indicates. The study finds that smaller snowstorms that drop a few inches will diminish greatly in number by late century. But the
