    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.

    Current understanding is that electricity savings in green commercial buildings are low or even negligible. New research, based on a sophisticated analysis of detailed energy data, proves that they do save energy, decrease environmental damage and reduce peak electricity demand.

    Climate change mitigation scenarios are finding a wider set of users, including companies and financial institutions. Increased collaboration between scenario producers and these new communities will be mutually beneficial, educating companies and investors on climate risks while grounding climate science in real-world needs.

    Wind facilities have generally deployed turbines of the same power and height in regular uniform arrays. Now, the modern generation of turbines, with customer-selectable tower heights and larger rotors, can significantly increase wind energy’s economic potential using less land to generate cheaper electricity.

    Quantitative scenarios from energy–economic models inform decision-making about uncertain futures. Now, research shows the different ways these scenarios are subsequently used by users not involved in their initial development. In the absence of clear guidance from modellers, users may place too much or too little confidence in scenario assumptions and results.
