Summary: Meeting energy needs and ensuring ecological sustainability are important tasks. This study investigates the influence of nuclear power and renewables on achieving carbon neutrality in major nuclear power countries. The findings show that nuclear energy reduces carbon emissions in Russia, while solar and wind power contribute to emission reduction in the U.S., Russia, and France. However, China's use of nuclear and renewables for carbon neutrality is inefficient.

Summary: To address climate change and achieve sustainable development, decarbonizing China's electric power system is crucial. This study examines the low-carbon transition and sustainable development of China's power system through 2035. The analysis suggests that rapid electrification will lead to a significant increase in electricity demand, requiring the replacement of coal-fired power generation with renewable energy. Incorporating electricity demand-side management is essential for an effective decarbonization pathway. The results of this study can provide guidance for policy makers in China and other emerging economies.

Summary: This paper provides estimates of marginal CO2 emissions from US electricity generation using the most comprehensive data, showing that while average emissions have decreased, marginal emissions have increased due to a shift toward greater reliance on coal. The research also highlights that the increase in electric vehicles may be offset by the emissions from the electricity sector if not significantly transformed.

Summary: This paper develops sustainability indicators for sixty alternative energy pathways and identifies the most sustainable pathways based on the quantitative impacts of power generation on water, air, land, and levelized cost of electricity (LCOE). The power generation stage of hydroelectricity has the most negative impact on water consumption and land use indicators, while having the lowest GHG emissions indicator. Geothermal flash technology with cooling tower and bio-oil with dry cooling are identified as the most sustainable pathways.

Summary: Households adopt solar panels mainly to reduce electricity bills, but the near zero marginal cost of solar power may lead to rebound effects that alter households' demand curve and distort the net effects of solar PV investments. Our analysis of high frequency data on household electricity consumption and production reveals a robust solar PV rebound effect of 7.7%, which is consistent across different sample and model specifications. We also observe that households shift their consumption to periods of higher solar electricity production. The solar PV rebound effect varies with time and production level, with larger rebound effects during seasons with higher solar irradiance.

Summary: This study investigates the effects of economic growth, health expenditure, and renewable and non-renewable energy consumption on CO2 emissions in Turkey. The findings suggest that GDP and non-renewable energy consumption are correlated with an increase in CO2 emissions, while health expenditure and renewable energy consumption are correlated with a reduction in CO2 emissions. The study recommends that Turkish policymakers promote economic growth through the use of renewable resources and invest more in health and renewable energy projects to combat environmental pollution.

Summary: In general, certified pathways for sustainable aviation fuels are not yet competitive with fossil kerosene, but certain options such as hydrotreatment of soybean oil, palm oil, used cooking oil, and beef tallow show potential. Among the pathways evaluated, residue-based options have lower mitigation costs, especially compared to 1G ethanol options like sugarcane ethanol. Mitigation costs of SAFs are currently much higher than carbon market prices, but SAFs could still play an important role in achieving aviation sector emissions goals.

Summary: The potential of Alternative Jet Fuels (AJF) to reduce greenhouse gases (GHG) emissions has discrepancies due to different accounting methods and Low-Carbon Policies (LCPs). Among food-based pathways, sugarcane-based AJF performs best, while soybean-based may have lower GHG reduction potential due to land use change. Residues-based pathways, particularly Fischer-Tropsch of lignocellulosic residues, show the highest potential for GHG reduction.

Summary: Biobased production is promoted as an alternative to fossil-based production to combat climate change, but concerns over sustainability have emerged. The OSiD framework aims to integrate context-sensitive sustainability analysis in the conceptual design of biobased processes, addressing tensions between different objectives and local concerns. This study illustrates a novel approach to integrating methods from various scientific disciplines to support sustainability analysis and identify tensions between different aspects early in the development of biobased production, with the goal of making them more responsive to emerging sustainability concerns in a global context.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
