Which countries are leading the way in sustainable energy?

As the threat of global warming continues, countries around the world are working hard to build a more sustainable way of living. One way they are doing this is focusing on delivering more sustainable energy solutions. So, which countries are leading the way in sustainable energy and why are they doing better than some other

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
