Summary: An innovative hydraulic hybrid excavator with an electrical hydraulic continually variable powertrain and energy regeneration system is proposed to save energy. The equivalent consumption minimization strategy is formulated to calculate control commands and reduce energy consumption. Test bench experiments verify the system’s energy saving efficiency ranging from 36.69% to 45.16%, effectively reducing fuel consumption and emissions of the hydraulic excavator.

Summary: The objective of this study is to analyze the role of energy efficiency and curtailment behaviors and examine how these behaviors are mediated by annual household income to explain overall energy consumption dynamics in US households using a nationally representative dataset. Our findings suggest that efficiency behaviors are positively correlated with the household income, but the direction of relationship between income and curtailment behaviors appears to vary depending upon specific actions. Our study provides important insights for tailored, targeted, and effective policies in residential energy saving behaviors.

Summary: China aims to peak carbon emissions by 2030 and become a carbon-neutral society by 2060. The building sector, responsible for over one-third of total carbon emissions, faces a significant challenge in helping China achieve these goals. The study conducted in Shenzhen shows that there is room for improvement in the city's energy conservation and carbon emissions reduction efforts, with the potential to reach peak carbon emissions in the buildings sector by 2025, 5 years earlier than the national target.

Summary: Reducing household energy consumption is crucial for decreasing fossil fuel use and greenhouse gas emissions, but some technologies do not have the expected impact. Homes without improvements had lower electricity consumption as users were solely responsible for electronic device operations, while energy conservation strategies led to lower energy bills but higher overall energy consumption.

Summary: This paper proposes an innovative powertrain and energy management strategy for hydraulic excavators, aiming to reduce energy consumption and emissions. The novel powertrain includes an engine, motor/generator, planetary gear, gearbox, and variable hydraulic pump. An energy regeneration system is applied to regenerate potential energy and charge the battery. An improved equivalent consumption minimization strategy is proposed to control the engine, motor/generator, hydraulic pump, and gearbox. Experimental results show that the proposed system achieves significant energy savings compared to current hybrid and conventional systems.

Summary: This study aimed to investigate the impact of motorcycle tyre rolling resistance coefficient on fuel consumption. The results showed that higher rolling resistance coefficient tyres led to increased fuel consumption. By reducing the rolling resistance coefficient, significant fuel savings can be achieved, with a potential saving of 16.6 million litres per year in Thailand with a coefficient of 12.0.

Summary: Fleet managers find that fuel consumption constitutes a significant portion of operating costs for vehicle fleets, leading transport companies to employ telematics services to track units and monitor fuel usage. This information is utilized to identify events that contribute to excessive fuel consumption and inform managers of the need for maintenance. The research proposed the use of this data to determine fuel consumption on specific roads, considering factors such as altitude, road grade, and vehicle age. The study conducted in Colombia's main logistic corridor demonstrated a strong correlation between actual and estimated fuel consumption, highlighting the potential benefits of utilizing this information for cost estimation, emission control, and determining areas with high fuel consumption. Additionally, the analysis found that altitude has a negligible effect on fuel consumption.

Summary: Minimizing carbon pollution and fossil fuels is crucial for sustainable development, but India's refusal to sign the global coal pledge has raised global environmental concerns. It is uncertain how India will achieve the 2070 carbon-free target with increasing coal and oil usage. This study examines the impact of fossil fuel efficiency, structural change, renewable energy consumption, technological innovation, and urbanization on carbon efficiency in India. The findings suggest that improving fossil fuel efficiency, structural change, renewable energy, and technological innovation can enhance carbon efficiency, while urbanization worsens environmental quality. The Indian government should invest in and incentivize technological innovation to support fossil fuel efficiency and renewable energy deployment.

Summary: The response of clouds to aerosol perturbations varies in time scales, with instantaneous effects and longer-term adjustments. Ship emissions of aerosols can affect cloud properties within a few hours, while cloud adjustments can continue for more than 10 hours. The temporal evolution and background cloud field are crucial in understanding the aerosol impact on clouds.
