The goal of achieving a zero-emission energy system by 2050 requires accurate planning to minimise the overall cost transition. Long-term models based on cost-optimal solutions are extremely dependent forecasts different technologies. However, such inherently uncertain. aim present work is identify pathway for Italian decarbonisation and assess how renewable scenarios can affect optimal solution. analysis has been carried out with H2RES model, single-objective optimisation algorithm Linear Programming. Different photovoltaics, on-shore off-shore wind power, lithium-ion batteries simulated. Results indicate that 100% in Italy technically feasible. Power-to-X technologies crucial balancing purposes, enabling share non-dispatchable generation higher than 90%. Renewable mix, however, both saturate maximum capacity potential almost all scenarios. Cost have significant impact their role hydrogen. Indeed, as battery costs rise, fuel cells emerge main solution services. This study emphasises importance conducting sensitivity analyses long-term planning. Such help determine changes may strategies decarbonising national systems.

Recent global events emphasize the importance of a reliable energy supply. One way to increase supply security is through decentralized off-grid renewable systems, for which growing number case studies are researched. This review gives overview levelized cost electricity (LCOE) these autonomous range from 0.03 $2021/kWh over 1.00 worldwide. The average LCOEs 100% systems have decreased by 9% annually between 2016 and 2021 0.54 0.29 $2021/kWh, most likely due reductions in storage technologies. identifies discusses seven key reasons why frequently overestimated or underestimated research, how this can be prevented future. employed verify findings on assess where might deployed costs evolve.

The energy transition is driving the adoption of local renewable production. Decentralised plants enable citizens to play an active role in generating and managing supplies. In Europe, recent policies are promoting Renewable Energy Communities (RECs), which consist aggregations end-users aiming produce share energy, cost-effective supply chains autonomously. A comprehensive analysis REC potential requires tools that integrate socio-economic, environmental, spatial evaluations for assessment. objective this study present current status capabilities modelling. This paper reviews twelve modelling have evaluation RECs. review structure follows steps a assessment process, structured background, inputs, simulation or optimisation outputs. Technical, economic, environmental aspects projects should be included without leaving behind spatialisation geographical planning new systems. Findings reveal co-existence multiple criteria not satisfied any tools, as most them mainly analyse few areas interest partially consider other aspects. comparison reveals financial outputs deepened. Meanwhile, marginal among both inputs Finally, software marginally spatializes workflow except CEA URBANopt, revealed complete options design.

Urban energy efficiency and sustainability are critical challenges, as cities worldwide attempt to balance economic growth, environmental sustainability, consumption. This systematic review examines the dynamics of urban management, focusing on how local authorities navigate transitions through measures, renewable adoption, policy interventions. Specifically, it seeks answer following research question: do implement energy-efficient practices adopt technologies reduce emissions, optimize cost-effectiveness, influence policy-making? The goal this study is assess effectiveness these approaches in different contexts. By reviewing 47 articles, identifies unique characteristics management highlights need for tailored, context-specific solutions, such integrating decentralized systems, optimizing building performance, developing incentives that consider socio-economic conditions. findings reveal varying degrees success among cities, with particular challenges lower-income municipalities, where financial institutional barriers hinder implementation sustainable projects. concludes localized long-term strategies essential achieving transitions, offering a comprehensive perspective complexities systems their evolving landscape. Future should focus assessing impact municipal policies, exploring innovative financing mechanisms integration, examining role digital management.

Energy system modelling may support policymakers in their energy planning efforts. modellers usually identify the optimal configuration based on an economic objective function, or multi-objective optimization, a combination of multiple objectives such as greenhouse gas emissions and total cost. However, there could be political, socio-economic, environmental reasons justifying policymaker's selection solution that is slightly more costly polluting than uniquely solution. Solely focusing disregards potentially diverse alternatives, which different evaluation metrics even preferable. In response to this challenge, near-optimal solutions gaining attention field extension traditional optimization studies way bridge gap between simulation approaches. study, we explore solutions, outline diversity evaluate relevance these context planning. The proposed methodology applied Italian case determine its potential tool evaluating scenarios from solutions.

In the field of energy system modelling, increasing complexity and optimization analysis are essential for understanding most effective decarbonization options. However, growing need intricate models leads to increased computational time, which can hinder progress in research policy-making. This study aims address this issue by integrating machine learning algorithms with EnergyPLAN EPLANopt, a coupling software multi-objective evolutionary algorithm, expedite process while maintaining accuracy. By saving we increase number evaluations, thereby enabling deeper exploration uncertainty modelling. Although have been widely employed as surrogate accelerate problems, their application modeling at national scale, preserving high temporal resolution extensive sector-coupling, remains scarce. Several were evaluated, an artificial neural network was selected model. The findings demonstrate that incorporating model within reduces time 64 % compared conventional EPLANopt approach, accuracy level close obtained running without
