Meeting global climate targets will lead to 8 million more energy jobs worldw...
26 Jul 2021 at 7:21am
Researchers created a global dataset of job footprints in 50 countries and used a model to investigate how trying to meet the Paris Agreement global climate target of staying well below 2°C would affect energy sector jobs. They found that action to reach said target would increase net jobs by about 8 million by 2050, primarily due to gains in the solar and wind industries.

Renewable energies: No wind turbine disturbing the scenery
20 Jul 2021 at 8:44am
In the Alpine foothills, in low mountain ranges, or on the seacoast, expansion of wind energy use often meets popular resistance. Researchers have now studied what this means for the energy transition.
No excuse to continue reliance on fossil fuels, says leading nano-technologist
20 Jul 2021 at 8:44am
One of the leading thinkers in nano-science has called on the energy materials community to help finally put an end to the world's reliance on fossil fuels.
Data identifies turbine wake clustering, improves wind farm productivity via ...
20 Jul 2021 at 8:44am
Researchers describe a real-time method for potentially helping turbine farms realize additional power from the clustering of their turbines. Their method requires no new sensors to identify which turbines at any given time could increase power production if yaw control is applied, and validation studies showed an increase of 1%-3% in overall power gain.
Making clean hydrogen is hard, but researchers just solved a major hurdle
19 Jul 2021 at 11:34am
Researchers have found a low-cost way to solve one half of the water-splitting equation to produce hydrogen as clean energy -- using sunlight to efficiently split off oxygen molecules from water. The finding represents a step forward toward greater adoption of hydrogen as a key part of our energy infrastructure.
Renewable energy OK, but not too close to home
19 Jul 2021 at 9:03am
When it comes to transitioning from carbon-based to renewable source energy systems, Americans are on board. They're less keen, however, having these new energy infrastructures built close to their homes.
Researchers discover a new inorganic material with lowest thermal conductivit...
15 Jul 2021 at 11:23am
A collaborative research team has discovered a new inorganic material with the lowest thermal conductivity ever reported. This discovery paves the way for the development of new thermoelectric materials that will be critical for a sustainable society.
New method makes vital fertilizer element in a more sustainable way
14 Jul 2021 at 12:11pm
Scientists and engineers have devised a new method for making urea that is more environmentally friendly than today's process and produces enough to be competitive with energy-intensive industrial methods.
Study evaluates biodiversity impacts of alternative energy strategies
13 Jul 2021 at 3:44pm
Climate change mitigation efforts have led to shifts from fossil-fuel dependence to large-scale renewable energy. However, renewable energy sources require significant land and could come at a cost to ecosystems. A new study evaluates potential conflicts between alternative energy strategies and biodiversity conservation.
Collective battery storage beneficial for decarbonized world
8 Jul 2021 at 7:36am
Batteries are potentially a game-changing technology as we decarbonize our economy, and their benefits are even greater when shared across communities, a new study has found.
More EVs could reduce CO2 emissions in Hawaii by 93% in less than 30 years
7 Jul 2021 at 3:53pm
By 2050, faster adoption of electric vehicles (EVs) and faster generation of renewable energy will result in 99% less fossil fuel consumed and 93% less CO2 emissions from passenger and freight vehicles on Oahu.
What to do with food waste? Well, that depends
7 Jul 2021 at 1:05pm
The expected decline in the number of landfills across the United States coupled with bans on disposing large amounts of organic waste in landfills that have been enacted in multiple states has prompted researchers to examine other ways to grapple with the issue of food waste disposal.
Solar hydrogen for Antarctica: Advantages of thermally coupled approach
2 Jul 2021 at 12:43pm
Their conclusion: in extremely cold regions, it can be considerably more efficient to attach the PV modules directly to the electrolyser, i.e. to thermally couple them. This is because the waste heat from the PV modules increases the efficiency of electrolysis in this environment. The results of this study are also relevant for other cold regions on Earth, such as Alaska, Canada, and high mountain regions, for example. In these places, solar hydrogen could replace fossil fuels such as oil and petrol.
