Reducing energy poverty through education

Because energy reaches into every facet of our lives, it is highly political. Biases and emotions run deep, and facts and data are often distorted, or worse.

It is a complex scenario and one that needs broad strategies to address globally. This is a problematic challenge when it crosses so many borders, philosophes, and differing political

Choosing a Low-Energy Sustainable Router

Many of the appliances, devices, and gadgets in our home drain energy when they are in use. For example, the fridge cycles on and off, and laptops only use power when charging the battery. The router you use to connect to the internet and read this article is an energy vampire you can tame. But

Aging population increases energy use

New research links two of the biggest drivers of global change today: the population’s rapid aging and the planet’s rising heat.

The research, among the first to explore how residential energy use changes over the human lifespan, finds that we use more energy as we age, that local climate changes energy-demand patterns, and that demand due

Wearable Patch: Personal Thermostat

Engineers at the University of California San Diego have developed a wearable patch that could provide personalized cooling and heating at home, work, or on the go. The soft, stretchy patch cools or warms a user’s skin to a comfortable temperature and keeps it there as the ambient temperature changes. It is powered by a

AI is on its way to becoming the brain of the grid

In May 2017, Bill Gates wrote an open letter to college graduates offering some career advice. In it, he said if he was starting out today, he’d consider entering one of these three fields: artificial intelligence, energy or bioscience. On artificial intelligence (AI), he said, “We have only begun to tap into all the ways

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 carry

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.

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 on

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 now,

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

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 materials

“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
