Transportation accounts for approximately 25% of European greenhouse-gas emissions. Of this, road transportation represents by far the largest percentage. While the COVID-19 epidemic briefly interrupted the rise in emissions, they've since resumed their upward climb.…

Sunday's protest was organized by a coalition of environmental protection groups including Extinction Rebellion, Nabu and Robin Hood. Several hundred people demonstrated Sunday against plans by Tesla to expand its electric car factory near Berlin, citing environmental concerns.…

Electric distribution infrastructure, shown from supply to end use, would likely require upgrades to facilitate new eVTOL charging sites. Credit: NREL Electric vertical take-off and landing (eVTOL) aircraft might quickly move passengers over mountains or float them across urbanscapes. But first, an important consideration for these flying batteries is where they will charge and whether the existing power grid infrastructure…

Credit: Chalmers University of Technology | Hanna Magnusson What we colloquially refer to as "e-scooters" can differ greatly when it comes to steering and braking capabilities, wheel size, and suspension systems; something that can have harmful consequences in the event of a crash. And it is the small, lighter e-scooters made for private use that are often more unsafe than the larger rental ones.…

Some studies estimate that 25% to 40% of traffic congestion in city centers is caused by people looking for parking spots. Not only does the quest for parking waste time and fuel, it also causes delays for other drivers and contributes to greenhouse gas emissions.…

Recommendations for action have been derived from the research results available to date that contain important findings for a nationwide expansion of…

Swirling flows, initiated when the tangential port opening exceeds 25%, have the potential to enhance the mixing of air and fuel. This can result in a more homogeneous mixture, leading to improved combustion efficiency and reduced emissions.
