Study finds reduction of low-frequency noise from transition to electric buses improved residents’ health

Green Car Congress

Accompanying the lower noise levels from bus traffic was a reduction of fatigue, day time sleepiness and low mood, a study at the University of Gothenburg shows. Previous noise-level measurements had indicated that disturbance from low-frequency noise in indoor environments was present in the residential area.

Study: Energy sorghum may combine best of annual, perennial bioenergy crops

Green Car Congress

Maize and other annual crops are easier to manage with traditional farming, but they are tougher on the environment. The question, before this study, was whether energy sorghum behaved more like miscanthus or maize, and what that meant for the ecosystem.

Baker Institute report: China has positioned itself as a gatekeeper to the energy transition; nickel case study

Green Car Congress

The LME events were a consequence of positions taken by Tsingshan based on expectations of falling prices. Batteries currently comprise about 7% of nickel demand, but this could increase to one-third of nickel consumption by 2040, which could create a disruptive supply chain environment for the US, according to the report.

Study using satellite data finds rate of urban growth much greater than previously thought

Green Car Congress

Each image captured 900 square meters of ground, a level of detail that allowed the scientists to study land-use change over time. An international team of researchers has used satellite images to map urban growth between 1985 and 2015. In a paper in Nature Sustainability , they report that global urban extent has expanded by 9,687?km
