LED bulbs often cost more in poor neighborhoods

In many low-income neighborhoods, upgrading to energy-efficient lightbulbs costs more than twice what it does in higher-income areas. Tony Reames of the University of Michigan led a research team that surveyed 130 stores across Wayne County, which includes Detroit. Reames: “Fewer stores in higher poverty areas even carried LED bulbs, but when they did, they

Crowd Oil – Fuels From Air-conditioning Systems

Researchers at the Karlsruhe Institute of Technology (KIT) and the University of Toronto have proposed a method enabling air conditioning and ventilation systems to produce synthetic fuels from carbon dioxide (CO2) and water from the ambient air. Compact plants are to separate CO2 from the ambient air directly in buildings and produce synthetic hydrocarbons which

Scientists 3D-print all-liquid ‘lab on a chip’

Researchers at DOE's Lawrence Berkeley National Laboratory (Berkeley Lab) have 3D-printed an all-liquid device that, with the click of a button, can be repeatedly reconfigured on demand to serve a wide range of applications -- from making battery materials to screening drug candidates. "What we demonstrated is remarkable. Our 3D-printed device can be programmed to

The shockingly simple way to make packaging more sustainable

If you quickly scan through the products under your sink–counter spray, window cleaner, dish soap–they all have one thing in common: Water is their main ingredient. Until now, few consumers thought this was a problem. But as a growing number of people become increasingly aware of both climate change and plastic pollution, the outsize environmental impact

Thermodynamic magic enables cooling without energy consumption

Physicists at the University of Zurich have developed an amazingly simple device that allows heat to flow temporarily from a cold to a warm object without an external power supply. Intriguingly, the process initially appears to contradict the fundamental laws of physics. If you put a teapot of boiling water on the kitchen table, it

Scientists turn carbon dioxide back into coal

Researchers have used liquid metals to turn carbon dioxide back into solid coal, in a world-first breakthrough that could transform our approach to carbon capture and storage. The research team led by RMIT University in Melbourne, Australia, have developed a new technique that can efficiently convert CO2 from a gas into solid particles of carbon.

Will Malaysia become Southeast Asia’s clean energy leader?

A silver lining of global warming is that it is forcing every nation to rethink its future, to open its mind to new possibilities. The latest IPCC report gives the world only 12 years to radically cut greenhouse gas emissions or condemn future generations to climate change catastrophe. There is no choice but to act.

New 2019 Factbook identifies key sustainable energy trends

The electricity sector continued to improve its carbon intensity in 2018 due to increased renewable energy and natural gas power generation and investments in energy efficiency, even as a stronger economy and volatile weather boosted energy demand and contributed to a rise in economy-wide carbon dioxide (CO₂) emissions. Consumers experienced near record low energy costs

Sweden Expands Support For Off-Grid Renewable Energy

SIDA, the Swedish International Development Cooperation Agency, is halfway through a 5-year commitment to bringing off-grid solar power to Zambia, one of the many countries that make up sub-Saharan Africa, where 70% of the people have no access to a functioning electrical grid. Those that do are often bedeviled with frequent interruptions of service and

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.
