Electricity demand is a crucial factor in energy system planning. Understanding future electricity demand is vital for developing effective energy and climate policies, as well as establishing a resilient and sustainable energy system. In light of these considerations, the escalating challenges posed by climate change are anticipated to have a substantial impact on electricity demand. This study, therefore, provides a comprehensive analysis delving into the dynamic nature of Temperature Response Functions (TRFs) of electricity demand across Europe. By examining various factors influencing electricity demand in residential buildings, such as thermal insulation, heating electrification, space cooling, and passive cooling, we aim to understand their collective impact on shaping future Temperature Response Functions. To project electricity demand, our study incorporates these factors into our scenario assumptions. Through a comprehensive investigation of these scenarios, our findings reveal distinctive regional influences of these factors. In regions where heating demand prevails, an initial increase in electricity demand is anticipated due to increased electrification rates. However, improved building thermal insulation is expected to substantially reduce winter electricity demand in the long run. Conversely, in regions with pronounced cooling demand, a notable escalation in electricity demand is foreseen due to increased space cooling penetration rate. Nevertheless, the application of effective passive cooling measurements is expected to mitigate and markedly diminish this increase. By highlighting the differential influences of these factors on electricity demand across Europe, our findings can offer valuable insights and guidelines first for energy system modelers for considering the change in Temperature Response Functions and second for policymakers to develop effective climate change adaptation and mitigation strategies. • Examination of the dynamic characteristics of Temperature Response Functions (TRFs). • Space and passive cooling, electric heating, insulation effects on electricity demand. • Projection of TRFs and electricity demand for 36 European countries until 2100. • Thermal insulation and passive cooling are essential for reducing electricity demand.

Healthcare organisations have a significant carbon footprint due to their substantial energy consumption and waste generation. The existing literature has mostly focused on examining the isolated impact of specific green organisational practices on individual dimensions of environmental performance. Hence, policy makers and practitioners still lack a holistic view of how combinations of green organisational practices can mitigate the impact on climate change of healthcare organisations. Drawing on the practice-based view (PBV) of strategy, the study first examines the extent to which the adoption of imitable, individual green organisational practices impacts on the whole climate change mitigation performance of publicly owned hospitals. Second, it explores possible combinations of green organisational practices that can lead to high levels of climate change mitigation performance. Focusing on the illustrative case of publicly owned acute care hospitals in the English National Health Service and employing a two-stage Data Envelopment Analysis and a fuzzy set Qualitative Comparative Analysis (fsQCA), the analysis shows that the adoption of the practice of green energy procurement can, in isolation, positively lead to high climate change mitigation outcomes. Moreover, high performance levels can be achieved through multiple configurations of green organisational practices. Therefore, the findings suggest that the effectiveness of green organisational practices on climate change mitigation performance of hospitals depends on how practices are combined, rather than on their single effects, and indicate the presence of a complementary as well as a substitution effect between practices.

• Extreme event experience links with greater willingness to pay for climate policy. • Wildfires and hurricanes have the strongest correlation with WTP. • WTP increases by $71-$106 for those who have experienced extreme events. • Extreme event experience could lead to $12 billion support/year for climate policy. We explore how extreme event experience relates to climate policy support in the U.S. We add three important yet uncommon elements to this field: we verify self-reports of extreme event experience with actual weather data; we use a willingness-to-pay measure to assess behavioral intention; and we analyze which types of extreme events have stronger impacts on WTP. People who self-report extreme weather events are willing to pay approximately $112/year more for climate mitigation policy than those who do not; people for whom those self-reports match recorded data are willing to pay $106 or $71 more (controlling for climate beliefs and political ideology and depending on how unverified reporters are treated). Wildfires have the strongest influence on WTP. Though our results show that political ideology correlates more strongly with policy support than does extreme event experience, extreme event experience exhibits a robust correlation with policy support, and could result in a minimum of billions of dollars of support annually for clean-energy policy alone.

The sustainability paradigm has gained global attention, and the same has been expected from the economies having increasing levels of environmental footprints over the past couple of decades. This research aims to investigate the nexus between clean energy technologies and climate change mitigation among the top ecologically pollutant (TEP) economies during 1996–2020. The research incorporated other drivers of climate change, including energy efficiency, industrialization, and sustainable policies through environmental regulations. The methodological context covers the necessary preliminary tests and the Method of Moment Quantile Regression (MMQR). The preliminary results indicate that TEP economies are interdependent with the heterogenous slope coefficients, stationarity data trends, and cointegrated relationships. The findings from the MMQR unveiled that clean energy technologies tend to mitigate climate change from 0.10th to 0.70th quantiles. Relatedly, energy efficiency reduces the environmental burden across all the quantiles except for the 0.10th one. Conversely, industrialization and economic growth cause an upward shift in climate change among TEP economies across all the quantiles, suggesting a need to shift production-based economies to more service-intensive ones. However, the study found no significant evidence for the nexus between sustainable environmental policies and climate change. The robustness checks also validate the MMQR estimations; however, their parameters' magnitude substantially varied. These outcomes encourage policymakers to implement holistic strategies supporting energy innovation, technologies, and efficiency improvements while controlling the adverse effects of industrialization and traditional growth models. [Display omitted] • Mitigating climate change needs a universal call. • A novel approach, MMQR, has been applied. • Both clean energy technologies and energy efficiency reduce ecological footprints. • Industrialization and economic growth disturb the sustainability paradigm.

The energy transition is at the core of sustainable development as it helps to combat global warming and climate change. Similarly, carbon markets also support the climate change mitigation. Therefore, by realizing the potential role of clean energy and carbon markets in ensuring environmental sustainability, this study analyzes the spillovers and connectedness between the environment (global carbon) and renewable energy sources (wind, solar, geothermal, biofuel, and fuel cell). The empirical analysis is conducted by applying the novel "TVP-VAR" connectedness framework of Balcilar et al. (2021) on the daily data over the period from August 1, 2014, to February 4, 2022. The findings show that solar and biofuel appear as the highest net shock transmitter among alternative renewable sources while global carbon is shown as the net receiver of shocks. The largest transmission of shocks to global carbon is observed from wind followed by solar. Although these findings support the connectedness between renewable energy and the environment, however this connectedness is influenced by economic crises such as the oil crisis and pandemic crisis. During COVID-19, the fuel cell was the highest transmitter of shocks. The results are important for policy formulation, investment, and portfolio management as they provide insights into the interconnectedness and help in boosting climate actions.

Reducing fossil fuels use while promoting the adoption of clean and renewable energy sources is crucial for mitigating climate change and attaining the sustainable development goals. This study investigates the driving forces of the share of non-hydroelectricity sources in total electricity generation. Using panel data of forty-six developed and developing countries over 1980–2011 and employing panel cointegration estimation techniques, we examine the key factors that influence the share of non-hydro renewable energy sources in the short and long run. The results of the study show that the driving factors have different impacts on the size and share of non-hydro renewable energy; and these impacts are mostly in the long run. Oil price increase and financial development has a significant positive effect on the amount and share of non-hydro renewable electricity generation. The impact of trade openness is ambiguous. Economic development enhances the size of non-hydro renewables but undermines its share in total electricity. Foreign direct investments, ratification of the Kyoto protocol, gross fixed capital formation and resource rent have no significant impact on non-hydro renewable electricity generation. Based on the results, appropriate policy recommendations are proffered. [ABSTRACT FROM AUTHOR]

[Display omitted] • Climate impacts of e-fuels can vary, depending on the source of electricity, CO 2 and H 2 , and their production technologies. • Today, e-fuels have smaller climate impacts than fossil fuels only if produced with a clean electricity source. • By 2050, stricter climate policies can decarbonize average European electric grid and cut climate impacts of e-fuels by 84%. • Climate change impacts of future e-fuels can be up to 58% lower than those of fossil fuels. • A clean electricity for H 2 production and the use of non-fossil CO 2 are key determinants of the climate benefits of e-fuels. 'E-fuels' or 'synthetic fuels' are hydrocarbon fuels synthesized from hydrogen (H 2) and carbon dioxide (CO 2), where H 2 can be produced via electrolysis of water or steam reforming of natural gas, and CO 2 is captured from the combustion of a fossil or biogenic source or directly from the atmosphere. E-fuels are drop-in substitutes for fossil fuels, but their climate change mitigation benefits are largely unclear. This study evaluates the climate change impacts of e-fuels for aviation by combining different sources of CO 2 and H 2 up to 2050 under two contrasting policy scenarios. The analysis includes different climate metrics and the effects of near-term climate forcers, which are particularly relevant for the aviation sector. Results are produced for European average conditions and for Poland and Norway, two countries with high and low emission intensity from their electricity production mix. E-fuels can either have higher or lower climate change impacts than fossil fuels, depending on multiple factors such as, in order of importance, the electricity mix, the origin of CO 2 , the technology for H 2 production, and the electrolyzer efficiency. The climate benefits are generally higher for e-fuels produced from CO 2 of biogenic origin, while e-fuels produced from CO 2 from direct air capture or fossil fuel combustion require countries with clean electricity to outperform fossil fuels. Synthetic fuels produced from H 2 derived from natural gas have higher impacts than fossil fuels even when coupled with carbon capture and storage, if CO 2 is sourced from fossil fuels or the atmosphere. Climate change impacts of e-fuels improve in the future, and they can all achieve considerable climate change mitigation in 2050 relative to fossil jet fuel, provided that strict climate policy measures are implemented to decarbonize the electricity sector. Under reduced policy efforts, future climate impacts in 2050 of e-fuels from atmospheric or fossil CO 2 are still higher than those of fossil jet fuels with an average European electricity mix. This study shows the conditions to maximize the climate change mitigation benefits of e-fuels, which essentially depend on progressive decarbonization of the electricity sector and on reduced use of CO 2 sourced from fossil fuels.

International political negotiations and national policy for climate change mitigation are increasingly focussed on the mobilisation and scale up of investments in clean energy infrastructure. This paper aims to develop the understanding of how institutional investors in the private sector perceive barriers to scaling up investment into clean energy infrastructure and what policy solutions to those barriers they advocate. This paper adds to existing scientific knowledge through a clear focus on private sector perceptions. Through the analysis of previous public statements from organisations and coalitions in the finance sector a number of investment barriers were identified. These initial barriers fed into a Delphi process. The outputs of the Delphi process were categorized into five sets of barriers and a number of policy solutions associated with investing into clean energy solutions. We conclude that there is a need for better engagement with the institutional investment community to ensure further effort on policy development that underpins investments at scale is effective and efficient.

In this study, we examine whether Willingness To Pay (WTP) for green energy is related to hope and several attitudes towards climate change, namely, denial, worry and level of understanding. Using cross-sectional data comprising answers from 905 respondents from the Netherlands, we find that people who are more generally hopeful are willing to pay more for green energy, but only if this hope is not based on denial of the severity of the issue. In addition, we find that WTP is associated with understanding and worry, and that these attitudes are even more closely related to WTP if they are accompanied by hope. Hope based on denial however strengthens the negative relation of a lack of worry and understanding with WTP. These findings highlight the importance of fostering realistic hopes regarding climate change to encourage sustainable behaviour, and could help to frame sustainability policies and measures in a way that maximizes people's willingness to support and contribute to investments in climate change mitigation.
