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

“Resilient” homes to withstand natural disasters

Since 1970, catastrophic events have quadrupled (The Economist) and in the US alone, the damage caused by hurricanes and fires amounted to 306 billion dollars in 2017. It is estimated that there are approx. 20 million refugees per year as a result of natural disasters; their number exceeds that of refugees due to wars and

Seawater turns into freshwater through solar energy

According to FAO estimates, by 2025 nearly 2 billion people may not have enough drinking water to satisfy their daily needs. One of the possible solutions to this problem is desalination, namely treating seawater to make it drinkable. However, removing salt from seawater requires 10 to 1000 times more energy than traditional methods of freshwater

How African cities can harness green technologies for growth and jobs

In 1967 one gigabyte of hard drive storage space cost US$ 1m. Today it's around two US cents. Computer processing power has also increased exponentially: it doubles every two years. This is just the tip of the iceberg when it comes to technological progress in the 21st century. There have also been tremendous advances in

ING: Green technologies could cut global energy emissions by 64%

During a recent research project entitled “technology – the climate saviour?” the Dutch bank undertook analysis exploring the potential impact of green technologies being installed at scale across seven sectors between 2019 and 2050 – namely power, heavy industry, real estate, light-duty vehicles (LDVs), trucks, shipping and aviation. The scenario, which ING claims is “positive

Greener Days Ahead for Carbon Fuels

For decades, scientists have searched for effective ways to remove excess carbon dioxide emissions from the air, and recycle them into products such as renewable fuels. But the process of converting carbon dioxide into useful chemicals is tedious, expensive, and wasteful and thus not economically or environmentally viable. Now a discovery by researchers at the

‘By working together we can scale up action for a greener future’

The 2015 Paris Agreement made clear that governments, businesses and civil society need to act together to bring about positive and permanent change for a greener, more inclusive future. Since then, we’ve seen commitments, national development plans, and increased investment. We’ve seen promising investments in renewable energy infrastructure, electric vehicle deployments, and energy-efficient buildings. But

Cohousing is an inclusive approach to smart, sustainable cities

The idea that technology will fix complex and systemic problems like climate change, poverty, the housing crisis or health care is simplistic to say the least. We need a radical shift in how we live, and designing for environmental and social sustainability cannot simply be about applying new technologies to our existing models of living.

Tales of microgrid ingenuity (and community)

Perhaps it’s my inborn bias towards news about technology companies (in my former journalism life, I covered the high-tech industry), but my mind keeps wandering this week back to the revelation in early November that software company VMware not only plans to build a microgrid at its Palo Alto, California, headquarters, it also is teaming up

Nigeria: Achieving electrification with smart micro-grids

An exclusive interview with Professor Xiongwei Liu, from Entrust Microgrid of the Lancaster Environment Centre in the UK, explores smart micro-grids based on hybrid DC/AC networks, for environments with renewables.  What in your view are the challenges to the energy sector in Nigeria and the region? The challenges facing the energy sector in Nigeria and broad

Consumers willing to pay more for sustainably brewed beer

More and more breweries are investing in practices to save energy and reduce greenhouse gases. Will it pay off? A study by Indiana University researchers suggests it may. Drawing on survey research, they find that a majority of U.S. beer drinkers would be willing to pay more for beer produced with sustainable practices. On average,

A new way to remove ice buildup without power or chemicals

From airplane wings to overhead powerlines to the giant blades of wind turbines, a buildup of ice can cause problems ranging from impaired performance all the way to catastrophic failure. But preventing that buildup usually requires energy-intensive heating systems or chemical sprays that are environmentally harmful. Now, MIT researchers have developed a completely passive, solar-powered
