Summary: This paper examines the impact of EU energy policies on European natural gas security of supply. It finds that the REPowerEU plan can significantly reduce gas demand and make Europe independent from Russian gas, but requires faster deployment of clean technology. On the other hand, the NECP19 plan maintains high gas demand and potentially exacerbates import dependence. Additionally, NECP19 introduces substantial inter-annual variation in gas demand, which is not fully addressed by the REPowerEU plan.

Summary: Given the significant number of existing buildings, achieving decarbonization of the building stock requires the development of new buildings designed to achieve optimal performance. Rather than simply aiming for nearly-Zero Energy Buildings (nZEB), the focus should be on Plus Energy Buildings (PEB) that have the potential to generate more energy than they consume over a specific time period. While several studies have investigated the potential for achieving a plus energy balance in buildings, there is still a lack of a comprehensive and widely accepted framework for designing and assessing the performance of PEBs. In order to address this issue, the authors have identified a series of key aspects that should be included in a consistent framework for PEBs, including factors such as balance contributions, physical boundaries, time span for balance assessment, metrics for evaluating PEBs, approaches for evaluating load matching and grid interaction, as well as the importance of Indoor Environmental Quality and user satisfaction as additional values of PEBs. By conducting a thorough review of existing literature on PEBs, the authors have laid the groundwork for proposing an approach to define PEBs and introduce an operational assessment focused on evaluating PEB performance during both the design and operational phases.

Summary: This study evaluates the natural resource use of gasoline vehicles, electric vehicles, hybrid electric vehicles, and fuel cell vehicles, finding that NGV production uses more than twice the resources required for GV production. The production of traction Li-ion batteries in EV production and fuel cells in FCV production accounts for a significant portion of total resource exploitation. The inverse trend between lifecycle TMR and CO2 emissions suggests that current transportation policies may be overlooking the environmental implications of resource exploitation.

Summary: The utilization of life cycle assessments in estimating the environmental impact of nuclear power generation has increased. However, the extraction of resources in the lithosphere has been insufficiently considered. This study uses total material requirement (TMR) as an indicator to analyze the resource use of nuclear power generation, accounting for the uncertainty associated with uranium ore grade. The research demonstrates that closed cycle reprocessing with MOX fuel has approximately a 26% lower resource use compared to the open cycle. The TMR of nuclear power generation varies depending on mining methods, with in-situ leaching having the lowest TMR and the greenhouse gas emissions are less affected by mining than resource use.
