Summary: In Mediterranean climate, green roofs have great potential for evapotranspiration and cooling energy saving, but this potential is limited by low rainfall. This research aims to determine energy savings by increasing water availability through irrigation systems. Computer simulations of three construction systems were conducted, studying different irrigation rates and schedules. Results show that increasing water input in extensive green roofs does not lead to increased evapotranspiration heat losses, and daily irrigation during cooling periods achieves the greatest energy savings.

Summary: The research demonstrates that evapotranspiration and volumetric water content have a significant impact on the reduction of heat flux in eco-roofs. The irrigation strategy plays a key role in improving the performance of eco-roofs. Eco-roofs can significantly reduce the energy demand of buildings and can be used as an efficient passive system for the rehabilitation of old buildings.

Summary: Climate change has significant impacts on irrigated agriculture and global food security. A study conducted in southern New Jersey evaluated the effects of climate change on irrigation demand, green water scarcity, and crop yields. The results showed that increased temperature and precipitation led to increased surface runoff and total streamflow. The study also found that corn yield, irrigation demand, and ET varied in response to climate change, while soybean exhibited a declining trend in ET and irrigation demand with increasing yield.

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 study compares the total energy consumption of households living in green certified buildings with those living in conventional buildings, finding that households in green certified buildings can save about 25% of total energy. The results suggest that energy policy measures, such as public information campaigns or subsidies for green certified buildings, can benefit energy savings and reduce emissions. However, it is important to consider that predicted energy savings may be higher than actual savings, impacting policy scenarios and measures implemented.

Summary: Liquid hydrocarbons made from crude oil have various functions, including serving as an energy source that is dense, easy to store and transport, and as a means of energy storage. They can also be used as a chemical feedstock, reducing agent, and for enhancing heat transfer in industrial processes. The demand for liquid hydrocarbons is essential in assessing the feasibility of alternative options, and it is projected that the US demand could range from 10 to 20 million barrels per day. Meeting such demands with biofuels from cellulosic feedstocks would require significant external inputs of heat and hydrogen, but options based on more limited feedstocks are inadequate.

Summary: The article sheds light on the importance of green investments in solving ecological crises, while also analyzing the theoretical origins and pitfalls of the Green Investment Paradigm. It highlights the reductionist, normative, disembodied, ahistorical and depoliticizing vision of the paradigm, and discusses the need for serious interdisciplinary assessment of the socio-political causes of ecological crises.

Summary: With the drawbacks of non-renewable energy sources becoming more apparent, the world is shifting its focus towards renewable sources. Among them, agricultural biomass, such as rice husk, has demonstrated great potential as a non-renewable energy source, especially in the extraction and synthesis of value added products. The quick reaction time and high utilization of agricultural biomass and waste have captured the interest of researchers worldwide. This review explores the sustainable applications of rice husk and rice husk ash in various engineering, industrial, and renewable energy applications, as well as comparing the achievable silica content from rice husk and other agricultural waste sources.
