    Modelling the network of power plants that supply a given city, and the amount of energy drawn from each plant, shows a city’s energy mix and demonstrates which other cities it shares most energy suppliers with.

    Vertical takeoff and landing aircraft (VTOLs), or “flying cars” can shorten commute time and could play a niche role in sustainable mobility. The authors estimate that over long distances, fully-loaded electric VTOL taxis could result in fewer GHG emissions than average occupancy ground-based cars.

    Carbon capture and storage can help reduce fossil-fuel power-plant emissions. Here the authors show that the energy return on input of thermal plants with carbon capture is in general lower than the energy return of most types of renewable energy even when combined with energy storage.

    The technical and economic viability of renewable energy (RE) based energy system is understudied. Here the authors utilized a LUT Energy System Transition Model to indicate that a carbon neutral electricity system can be built in all global regions in an economically feasible way but requires evolutionary changes for the following 35 years.

    Water constraints can affect plans to expand electricity capacity. This study shows that in the United States such constraints can increase the cost of electricity generation with slightly reduced electrification of end-use sectors, and can incentivize early retirement of water-intensive technologies.

    There has been a divide between scientists making recommendations for sustainable natural resource development and the community living around those resources. Masami Nakagawa argues that the community should be considered first, as the successful development of sustainable natural resources requires their cooperation and trust.

    To meet the Paris Agreement goals, CO2 emissions in industrial countries must decrease over the long term. Now research shows that an increase in the share of renewable energy and a decrease in energy use have contributed to emissions reductions in industrial countries, but enhanced policies are needed to decouple economic growth from emissions.

    Global emissions rose in 2018 with the USA increasing its emissions after three years of decline. Understanding the contributing factors is not enough — action at all scales is needed.
