Summary: This paper presents an analysis of energy and exergy for a thermochemical hydrogen production facility based on solar power. Different thermochemical cycles are compared, and the use of a recompression S-CO2 Brayton power cycle is found to enhance system performance. The maximum achieved efficiency is 27%, and the energy and exergy efficiencies vary with solar radiation and concentration ratio. The solar energy unit is identified as the main source of exergy destruction.

Summary: Energy efficiency is crucial in addressing climate change, and different countries use various methods to estimate energy savings. Improved measurement methods are adopted in countries with mandatory energy efficiency targets, using bottom-up and top-down approaches. India has implemented energy efficiency measures, estimating the impact through a simplified bottom-up approach. The use of Index Decomposition Analysis is limited due to data constraints. This study uses India's energy balance data to estimate energy efficiency savings, finding differences with government estimates. Improved methods and data reliability are important for accurate energy savings measurement, with national targets promoting advancements in measurement techniques and addressing market barriers.

Summary: The increase in consumption and resource use linked to human activity poses risks to energy security and sustainability, leading to a global restructuring of policy agendas to integrate environmental well-being through channels such as energy efficiency (EE). This study aims to analyze the relationship between energy efficiency, renewable energy, and financial development. Using a spatial econometrics model, the research finds spatial autocorrelation of EE among European countries and observes that the use of renewable energies promotes EE in neighboring economies. On the other hand, financial development has both positive and negative effects on EE, with the institutional component showing a positive impact and the stock market component showing a negative impact. The findings highlight the importance of renewable energy use in improving EE and the need for policy makers to develop mechanisms for greener and more sustainable development while encouraging efficient energy use.

Summary: Energy conservation policies of buildings (ECPB) involve national plans, laws, and regulations to improve energy efficiency and reduce carbon emissions. However, increasing the effectiveness of national policy is challenging due to historical, social, economic, and environmental complexities. Future policy designs should be careful and scientific, building on past achievements and addressing existing problems.

Summary: A working mechanism of air energy-assisted solar drying was developed to overcome discontinuities caused by weather conditions and daylight. By using an air-energy assisted solar dryer, timber was dried from a green moisture content of 183% to 11.3% in 161.5 hours, with a moisture diffusion coefficient ranging from 1.28 x10-10 m2/s to 6.41 x10-9 m2/s. The effective solar radiation intensity during drying ranged from 221.3 to 750.3 W/m2. The energy-assisted solar dryer showed suitability for low radiation and various weather conditions.
