Can the Digital Economy Enable Carbon Emission Reduction: Analysis of Mechanisms and China’s Experience

With the continuous advancement of global scientific and technological capabilities, the issue of global warming caused by greenhouse gas emissions has received widespread attention from countries worldwide. Promoting carbon reduction and curbing the trend of global warming have become urgent and significant challenges for China and the world. Therefore, it is of great practical significance to explore the impact and mechanism of the digital economy on carbon reduction. This paper empirically analyzes the impact and means of the digital economy on carbon emissions using panel regression models and mediation effect models. The research indicates that the digital economy significantly impacts carbon emissions, and the following main conclusions are drawn: (1) The influence of the digital economy on carbon intensity exhibits an inverted U-shaped curve, starting with promotion and then inhibition. (2) The digital economy can affect carbon emissions through industrial structural upgrading and technological innovation. (3) Regions with a relatively high level of digital economy development also tend to have higher energy utilization efficiency, leading to a more pronounced impact of the digital economy on carbon emissions levels.

The Development and Validation of Correlation Charts to Predict the Undisturbed Ground Temperature of Pakistan: A Step towards Potential Geothermal Energy Exploration

As a country, Pakistan is mostly dependent on fossil fuels for fulfilling its energy demand, which is expensive, as well as being environmentally unfriendly. It is high time that the country decides to shift from fossil fuels to renewable energy resources like geothermal, wind, solar, etc., to cater for global warming issues. Pakistan has a lot of potential geothermal sites, as the location of Pakistan lies on several fault lines and hot springs, thus making it very easy to extract the temperature from deep inside the earth and harness it for Geothermal Energy. Also, a sound knowledge of ground temperature is essential to use geothermal energy, which is obtained by drilling boreholes and putting in sensors. However it becomes a very expensive and labor intensive procedure. Therefore, to avoid the huge cost for drilling boreholes, particularly for ground temperature analysis, a numerical approach has been considered for determining ground temperature. Furthermore, correlation charts between air and ground temperatures have been developed, as there were no proper studies on the ground temperature of Pakistan. Then, with the help of a boreholes drilled in the National University of Sciences and Technology, Islamabad, Pakistan, the actual ground and numerically calculated temperatures have been compared. The results show a temperature error margin in the range between 0.27% for higher depths of about 5.6 m and 7.3% near the surface of about 2.7 m. Thus, it is shown that the proposed method is easy to implement and better than large scale testing methods for the depths at which geothermal energy is extracted.

Literature Study on Conditions of Sea Surface Temperature and Seawater Rise in Indonesia Detected by Remote Sensing

The Sea Surface Temperature (SST) is an important parameter for climate dynamic issues either globally or regionally as well as for global warming issues. In some condition the parameter can cause melting glaciers that will influence the rise of the sea levels. The further effect will be the climate change with the weather phenomena such as storms, hurricanes and heavy rains. As the result, the changes of the planting seasons occur and all of these will harm human life on earth. If there is no prevention with the condition of the parameter it is predicted that by 2040 the sea levels will rise highly because of the melting polar ice caps that will cause the sink of theislands. The SST has been detecting using remote sensing methods for 32 years in Indonesia. The trend has increased to reduce the damage of infrastructure and the activity disturbance of coastal communities. Indonesian country optimistically commits to achieve the target of net zero emission by 2060. The Indonesian government has stated nationally the climate target commitments determined for Indonesia and will strive to maintain the main target of reducing greenhouse gas emission into 41% by 2030.

Biochar: Pemanfaatan dan Aplikasi Praktis

Biochar is a carbon-rich solid produced from the pyrolysis of biomass such as wood, manure, and leaves under high temperature and low oxygen conditions which is used for agricultural applications as a soil amendment. This paper reviews the utilization and practical application of biochar. The application of biochar into the soil can improve the physical, chemical and biological properties of the soil, namely increasing porosity, water holding capacity, soil aggregation, increasing pH, cation exchange capacity, soil organic carbon, nutrient retention and availability, and increasing microbial life, meso and soil macrofauna. Aside from being a soil amendment, biochar has a function on issues of global warming, climate change, and the environment, namely its role in carbon sequestration and stabilization, greenhouse gas emissions, and soil pollutant remediation. If biochar is applied properly, namely using the right feedstock materials, method of manufacture, dosage, method of application, and place, it will affect agronomic performance and crop yields. Reduced yields are mostly occured in temperate climates as biochar significantly increases soil pH causing an effect of excessive liming resulting in immobilization of key nutrients such as Mg, Fe, B, and P. Biochar needs to be mixed or applied together with fertilizer ingredients such as chemical fertilizers, bio-fertilizers, compost, and manure. Another effort is to enrich biochar with those materials so that biochar is categorized as a biochar-based fertilizer that has a higher selling price.

Synergistic effect of silica aerogel and titanium dioxide in porous polyurethane composite coating with enhanced passive radiative cooling performance

Passive daytime radiative cooling is a promising technology that can mitigate the increasing issues of global warming and urban heat island effects. In this work, a series of porous polyurethane (PPU) composite coatings containing silica aerogel (SA) and/or titanium dioxide (T) were prepared though a wet phase inversion method. The effects of the filler types on relevant properties of composite coatings, such as pore microstructure, radiative cooling, mechanical, and hydrophobic performances, were systematically investigated. The typical PPU-SA10@T10 composite coating showed an interleaving porous structure, and the incorporated SA and T fillers were uniformly stacked in the pore cavities. Taking advantages of the strong light-back scattering and molecular oscillation functions, the solar reflectance, thermal emittance in the atmospheric transparency window, and the net cooling power of the PPU-SA10@T10 coating reached 0.917, 0.973, and 87.8 W/m2, respectively, which results in a sub-ambient cooling of 7.8 °C at midday under a solar irradiance of ∼640 W/m2. Moreover, the PPU-SA10@T10 coating possessed well balanced mechanical properties and superior hydrophobicity (water contact angle was 121.7°). The present work provides a viable way for developing radiative cooling coating with desirable mechanical properties and water-repellency.

Bibliometric analysis on hybrid renewable energy-driven desalination technologies

Throughout human history, water and energy have played pivotal roles in the expansion and progress of societies. However, the availability of fresh water on Earth is limited, constituting less than 3% of the global water resources. Moreover, the distribution of freshwater across countries is inequitable, with a considerable amount being returned to oceans and underground reservoirs. The escalating effects of global warming further disrupt the natural water cycle, posing a serious threat to numerous countries in the form of drought and famine. To meet the increasing demand for freshwater, desalination technologies have been widely employed worldwide. Nevertheless, most of the existing commercial desalination methods heavily rely on fossil fuels and contribute to significant greenhouse gas emissions, exacerbating the issue of global warming. Consequently, the integration of hybrid renewable energy sources into desalination processes emerges as a promising solution to simultaneously address the freshwater demand and combat global warming. So, utilizing hybrid renewable energy supply to drive various desalination technologies is a very promising solution to meet freshwater demands and help mitigating the global warming problem. Therefore, it is imperative to gain a comprehensive understanding of the latest advancements in hybrid renewable energy-driven desalination technologies to guide future research endeavors in this domain. The primary objective of this study is to perform a bibliometric analysis in order to identify the key sources, authors, countries, research institutions, and topics within the field of hybrid renewable energy-driven desalination technologies. By utilizing the R Bibliometrix library and the biblioshiny application, a dataset comprising 451 publications obtained from the Scopus database was analyzed. The results of the analysis reveal a substantial increase in the annual publication rate within this research field over the past five years. Notably, Iran, the United States, and China have emerged as leading contributors in terms of total publications. However, it is noteworthy that countries in the Middle East and the Mediterranean region, in addition to China and the USA, exhibit prominent involvement in various categories of research within this field.

Numerical study on the use of ammonia/hydrogen fuel blends for automotive spark-ignition engines

The importance of new alternative fuels has assumed great relevance in the last decades to face the issues of global warming and pollutant emissions from energy production. The scientific community is responsible for developing solutions to achieve the necessary environmental restriction policies. In this context, ammonia appears as a potential fuel candidate and energy vector that may solve the technological difficulties of using hydrogen (H2) directly in internal combustion engines. Its high hydrogen content per unit mass, higher energy density than liquid hydrogen, well-developed infrastructure and experience in handling and storage make it suitable to be implemented as a long-term solution. In this work, a virtual engine model was developed to perform prospective simulations of different operating conditions using ammonia and H2-enriched ammonia as fuel in a spark-ignition (SI) engine, integrating a chemical kinetics model and empirical correlations for combustion prediction. In addition, specific conditions were evaluated to consider and to understand the governing parameters of ammonia combustion using computational fluid dynamics (CFD) simulations. Results revealed similar thermal efficiency than methane fuel, with considerable improvements after appropriate H2-enrichment. Moreover, increasing the intake temperature and the turbulence intensity inside the cylinder evinced significant reductions in combustion duration. Finally, higher compression ratios ensure efficiency gains with no evidence of abnormal combustion (knocking), even at high compression ratios (above 16:1) and low engine speeds (800 rpm). Numerical simulations showed the direct influence of the flame front surface area and the turbulent combustion velocity on efficiency, reflecting the need for optimizing the SI engines design paradigm for ammonia applications.

Analysis of Climate Variability and Trends for Climate-Resilient Maize Farming System in Major Agroecology Zones of Ethiopia

Maize is one of the most important cereal food crops, and it can be grown all year in various agroecological zones. However, its vegetative growth and yield are susceptible to rainfall and temperature variability. As a result, the analysis of rainfall and temperature variability and trend was urgently needed in maize-growing agroecology zones to restructure the production system. The aim of the study was to examine rainfall and temperature variability and trends for developing a climate-resilient maize farming system in major agroecology zones in northwest Ethiopia. The study was implemented in low productive agroecology zones (LPZ), medium productive agroecology zones (MPZ), and high productive agroecology zones (HPZ) of northwest Ethiopia using daily time series climate data during the period 1987–2018. The coefficient of variation (CV), precipitation concentration index (PCI), rainfall anomaly index (RAI), and standardized precipitation (SPI) were applied to examine rainfall variability. Mann–Kendall’s and Sen’s slope estimator trend tests were used to detecting the statistical significance of changes in rainfall and temperature. Statistically significant increasing trends for annual maximum and minimum temperatures were recorded for all maize-producing agroecology zones. The mean annual temperature has exhibited a significant warming trend of 0.12 to 0.54°C per decade. The average annual rainfall has decreased by 38 to 67 mm per decade in all maize agroecology zones. Our research also showed that droughts now happen every one to three years; even consecutive droughts were seen in 2009, 2010, and 2011. For this reason, it could be required to develop a system of climate-resilient maize farming to address the issues of both global warming and the sub-Saharan countries that make up our study area. Climate-resilient maize agronomic activities have been determined by analyzing the onset, length of the growth period (LGP), and cessation date. Accordingly, the lower and upper quartiles of the date of onset of rainfall were in a range of May 9 to June 2, respectively; the length of the growth period (LGP) during the rainy season ranges from 97 to 232 days, and the cessation date of rainfall was November 1. Therefore, the short- to long-maturing maize varieties can be planted from May 9 to June 2 and can begin to be harvested in the first week of November under the current climatic circumstances.

Decarbonization through sustainable energy technologies: Asymmetric evidence from 20 most innovative nations across the globe

Since the discharge of carbon is one of the main causes for ongoing global warming issue and change in climate, most nations have committed to decarbonizing their economies at the COP26 summit. Thus, this investigation aims to explore the consequences of innovations in sustainable energy technologies on decarbonization in the 20 most innovative nations across the globe. In assessing the cause-and-effect relationship, we have used “Panel Non-linear Autoregressive Distributed Lag (P-NARDL)” technique. The findings demonstrated that the variables have a lasting relationship. The positive asymmetric shock in the innovations in sustainable energy technologies has a positive influence on the decarbonization of these nations, while the negative asymmetric effect is insignificant. According to the findings, clean energy negatively consequence on carbonization whereas growth in economy is favorably and considerably connected with it. The findings demonstrate that there is bidirectional causation between all variables under investigation, with the exception of the unidirectional causality flows from the usage of sustainable energy technology and emissions of CO2. In a global context, this research suggests that government should identify the roles of new sustainable energy technologies by reforming patenting regulations to rectify the environmental damages.

Urbanization Heat Flux Modeling Confirms It Is a Likely Cause of Significant Global Warming: Urbanization Mitigation Requirements

Recent ground-based measurements find the magnitude of the urbanization effect on the global average annual mean surface air temperature corresponds to an urbanization contribution of 12.7%. It is important to provide modeling to help understand these results as there are conflicting concerns. This study models the global warming contribution that urbanization heat fluxes (UHF) can make due to anthropogenic heat release (AHR), and solar heating of impermeable surface areas (ISAs), with additional secondary effects. Results help explain and support ground-based observations. Climate models typically omit anthropogenic heat release (AHR) as warming estimates are below 1%. In agreement, the baseline assessment in this paper has similar findings. However, in this study, the methods of climate amplification estimates (MCAE) with data-aided physics-based amplification models are used. When the MCAE are applied at the global and microclimate levels that consider greenhouse gases (GHGs), feedback, and other secondary effects; the results show that AHR fluxes can amplify, increasing to have an estimated global warming (GW) influence of 6.5% from 1950 to 2022 yielding a 0.9% decade−1 increase. This increasing rate due to energy consumption is found as anticipated to be reasonably correlated to the increasing population growth rate over this time. Furthermore, using the MCAEs, this paper studies heat fluxes assessment due to solar heating of unshaded impermeable surfaces including likely secondary amplification effects. Impermeable surface areas (ISAs) such as asphalt roads, roofs, and building sides have been reported with high land surface contact temperatures (LSCTs) relative to non-ISAs and significantly found to contribute to urbanization warming. Results indicate that high-temperature unshaded impermeable surfaces (including building sides) are estimated to average around 10–11 °C above the earth’s ambient temperature of 14.5 °C (showing albedo ISA estimates between 0.133 and 0.115 respectively); the ISA heat fluxes with secondary effects are estimated to have about a GW influence of 6.5%. This is broken down with average contributions of 4.0% from urban ISAs and 2.5% from rural ISA heat fluxes. Asphalt road ISA heat fluxes are estimated to have about a 1.1% global warming influence. Then the total UHF effect from ISAs and AHR with secondary effects is assessed in modeling to yield a combined average GW influence of 13% helping to confirm ground-based measurement results. Several key adjustment values were used for shading, cloud coverage, and rural-to-urban ISA ratios. Microclimate GHGs and related water vapor feedback (WVF) were assessed to increase urban warming by about 50%. As well an assessment of water vapor and radiation increases from UHF is provided. This study also shows the need to incorporate urbanization heat fluxes with secondary effects into climate models and indicates the necessity for Paris Agreement urban heat flux mitigation goals. Results also found that given average climate conditions, it is possible to mitigate much of the UHI effect with an albedo increase of 0.1 that is anticipated to lower the average impermeable surface temperatures by about 9 °C. Studies show this can be accomplished with cost-effective cool roads and roofs. Although roads are only estimated to occupy 14% of ISAs, changing roads from asphalt to concrete-type surfaces would improve reflectivity by about a factor of 5 and is estimated to mitigate about 5.5% of global warming. Unfortunately, the current overuse of black asphalt on pavements and roofs is highly dangerous to our environment causing UHI increases in heatwaves, excessive temperatures, and global warming issues and should be banned. Asphalt usage also reduces opportunities for solar geoengineering of urbanization.

Large Scale Cultivation and Pretreatment Optimization of Freshwater Microalgae Biomass for Bioethanol Production by Yeast Fermentation

The rapid depletion of the world’s fossil fuel reserves and global warming issues have promoted the search for sustainable alternative energy resources. In the present investigation, large-scale cultivation of naturally isolated freshwater microalgae Asterarcys quadricellulare strain was carried out using tertiary treated municipal wastewater as a growth medium in an open HRP pond for bioethanol production. A total of 12.091 kg of dry biomass was obtained at the end of the study. The lipid extracted carbohydrate rich spent microalgae biomass was converted to bioethanol by ethanolic fermentation. The biomass was first pre-treated with different concentrations of H2SO4 and HCL hydrolysis with different temperatures and reaction times. The biomass treated with a 2.0% concentration of H2SO4, showed maximum yields of glucose 308.38 mg.g-1 at 100°C with 180 min reaction time. The hydrolysates derived from the hydrolysis of microalgae biomass were used as a substrate for fermentation by using S. cerevisiae. The obtained bioethanol was analyzed using HPLC and the purity of ethanol was 90%.

Denunciation of Treaty in International Politics: A Critical Analysis of US’ Renunciation from the Paris Climate Change Agreement

Since the wake of the Westphalia Peace (or Treaty) in 1648, the idea of treaty has become handy and instrumental to the conditioning of the globe and maintenance of peace in the international arena. One of such treaties is the Paris Climate Agreement entered by states to forestall global warming and other climatic issues. It is however, problematic to note that states now willingly opt out of agreements entered in the international arena. This study sets out to interrogate why states denounce treaties, focusing on President Donald Trump’s choice to pull US out of Paris Climate Agreement. The study is anchored on the theory of Rational Actor Model, causal research design, documentary method of data collection, and content analytical method of data inquiry and analysis. The study argued that the concern of reduced economic competitiveness, conditional commitments, and nationalistic thinking are to be considered as US reasons for Paris Climate Treaty denunciation. The study deciphered that US’ choice to pull out of the Paris Climate agreement under Donald Trump’s presidency is not unconnected to Trump’s rationalistic choice or idea to put US first and make her great through nationalistic economic policies devoid of global influences, and global economic bazar, which he saw as wasteful venture. The study recommended that humanity needs all hands (states) on deck to combat the common enemy of global warming occasioned by climate change. Hence, the treaty through a more accommodating and friendly protocol should be sustained by all parties. 

Exergy analysis of reversible sofc coupled with organic Rankine cycle and hydrogen storage for renewable energy storage

Due to the ever-rising demand for energy and the need to address the critical issue of global warming, the focus on efficient energy systems driven by renewable energy has gained a lot of attention. Integrating fuel cells with renewable energy is a very attractive and promising solution to achieve this aim. In this study, a novel tri-generation system is presented and analysed for its exergetic performance. A Metal hydride hydrogen storage (MHHS) system is used in the study to supply hydrogen to the Solid oxide fuel cell (SOFC). In the ORC cycle, n-octane is selected as the working fluid due to its high critical temperature. Exergy analysis of the overall system helps in finding out the system components where the most energy is getting degraded. For the analysis, the exergy efficiency pertaining to net electrical power output, heating and cooling performance and tri-generation is considered as the basis of exergy assessment. MATLAB is used to develop a steady-state Parametric analysis is performed by varying the important parameters such as SOFC current density, SOFC temperature and pressure at the turbine inlet. As per the outcome of the present study, the maximum exergy efficiency was reported to be 46.5% at specific operating conditions. The ORC evaporator, heating application and fuel heat exchanger were the major sites for the exergy destruction with values of 258 kW, 175 kW and 91 kW respectively. Also, a maximum gain in exergy efficiency of around 17.4% was reported after incorporating a tri-generation system instead of power cycle alone.

Organic Farming in India and its Way Forward

India is home to 30% of the world’s organic growers and is likely to expand in the coming years. The solutionto the issues of sustainability, global warming, land degradation and food security is Organic Farming, which is seen as a sign of dynamic change for the agricultural industry. Organic Farming discards the use of synthetic fertilizers and promotes sustainable agricultural practices. Organic Farming holds immense potential to revive the degrading state of the agricultural sector in the world by offering environmental benefits, quality products and conserving non-renewable resources. It is a promising alternative to conventional farming and is expanding quickly. Organic Farming is gaining worldwide attention with 2.30 million hectares of land being used for the purpose. It helps to reduce greenhouse gas (GHG) emissions and improves soil fertility, boosting productivity and crop health. Organic Farming can also be used for land reclamation purposes. The aim of the present study is to examine the development of Organic Farming in India and globally, as well as identify any potential barriers to its implementation.

Resent Development of Binder-Free Electrodes of Transition Metal Oxides and Nanohybrids for High Performance Supercapacitors - A Review.

The entire world is aware of the serious issue of global warming and therefore utilizing renewable energy sources is the most encouraging steps toward solving energy crises, and as a result, energy storage solutions are necessary. The supercapacitors (SCs) have a high-power density and a long cycle life, they are promising as an electrochemical conversion and storage device. In order to achieve high electrochemical performance, electrode fabrication must be implemented properly. Electrochemically inactive and insulating binders are utilized in the conventional slurry coating method of making electrodes to provide adhesion between the electrode material and the substrate. This results in an undesirable "dead mass," which lowers the overall device performance. In this review, we focused on binder-free SCs electrodes based on transition metal oxides and composites. With the best examples providing the critical aspects, the benefits of binder-free electrodes over slurry-coated electrodes are addressed. Additionally, different metal-oxides used in the fabrication of binder-free electrodes are assessed, taking into account the various synthesis methods, giving an overall picture of the work done for binder-free electrodes. The future outlook is provided along with the benefits and drawbacks of binder-free electrodes based on transition metal oxides.

Benessere epistemico, mass media, disinformazione e cambiamento climatico

The article analyzes one of the crucial junctures in the fight against climate change, namely its relationship with the media and disinformation. A dense network of actors is involved in the creation and dissemination of disinformation that has long been supported by the economic interests of the oil and coal industries and is now fully embedded in the post-truth climate. The absence of direct experience and perception of the effects of climate change has emphasized the public’s cognitive dependence on the media, which, however, have lagged far behind and manifested inadequacy with respect to the emergence of the global warming issue. In dialogue with a vast scientific literature and Pew research data, the paper analyzes the widespread post-factual and social attitudes ranging from skepticism to outright militant denialism.In this context, the article proposes and signals the need for a healthy epistemic environment, understood as an indispensable index of the quality of democracy and of critical subjectivity as a preconditions for any positive action against countering climate change.

Second-Generation Bio-Fuels: Strategies for Employing Degraded Land for Climate Change Mitigation Meeting United Nation-Sustainable Development Goals

Increased Greenhouse Gas (GHG) emissions from both natural and man-made systems contribute to climate change. In addition to reducing the use of crude petroleum’s derived fuels, and increasing tree-planting efforts and sustainable practices, air pollution can be minimized through phytoremediation. Bio-fuel from crops grown on marginal land can sustainably address climate change, global warming, and geopolitical issues. There are numerous methods for producing renewable energy from both organic and inorganic environmental resources (sunlight, air, water, tides, waves, and convective energy), and numerous technologies for doing the same with biomass with different properties and derived from different sources (food industry, agriculture, forestry). However, the production of bio-fuels is challenging and contentious in many parts of the world since it competes for soil with the growth of crops and may be harmful to the environment. Therefore, it is necessary to use wildlife management techniques to provide sustainable bio-energy while maintaining or even improving essential ecosystem processes. The second generation of bio-fuels is viewed as a solution to the serious issue. Agricultural lignocellulosic waste is the primary source of second-generation bio-fuel, possibly the bio-fuel of the future. Sustainable practices to grow biomass, followed by their holistic conversion into ethanol with desired yield and productivity, are the key concerns for employing renewable energy mix successfully. In this paper, we analyze the various types of bio-fuels, their sources, and their production and impact on sustainability.

Numerical modelling of rotating packed beds used for CO2 capture processes: A review

AbstractOver the last decades, renewable and clean energy sources are being rigorously adopted along with carbon capture technologies to tackle the increasing carbon dioxide (CO2) concentration level in the environment. CO2 capture is a quintessential option for tackling global warming issues.
