As urban growth increases stress on global systems, researchers are working to develop solutions that contribute to the livability of future cities. When it comes to urban energy - and its ever-increasing consumption - they believe resiliency, reliability and accessibility will be critical factors in ensuring a sustainable supply.
In the future more and more cars will fill up with electricity instead of petrol - ideally, electricity from wind, water or solar energy. A prerequisite for the energy turnaround is the availability of efficient storage media. Scientists at the Technische Universität München are working on the optimal battery cell.
The work will focus on developing 'sustainable catalysis', finding ways to increase the energy efficiency of the manufacture of important chemicals used in huge quantities to produce products that are part of our everyday life, and use renewable materials to make those chemicals, ideally having them begin their lives as biomass, rather than as petrochemicals.
Addressing climate change will require substantial new investment in low-carbon energy and energy efficiency - but no more than what is currently spent on today's fossil-dominated energy system, according to new research.
Wind and solar together account for just under half of the total 2.7TW of net new power capacity in the region, driven by improving cost-competitiveness, and renewables in total account for 63% (1.7TW).
The net-zero energy test house at the National Institute of Standards and Technology (NIST) in suburban Washington, D.C., not only absorbed winter's best shot, it came out on top, reaching its one-year anniversary on July 1 with enough surplus energy to power an electric car for about 1,440 miles.
Could playing video games help people understand and address global sustainability issues such as pollution, drought or climate change? At least two researchers believe so, outlining their argument in a concept paper.
The SOPCAWIND project has developed new software to optimize wind farm placement in Europe, taking into account criteria as varied as wind power, local environment characteristics, potential interference with communication systems, noise, nearby housing exposure to the sun, visual impact or even the existence of archaeological artifacts on site.
