A Review on Solar Energy Policy and Current Status: Top 5 Countries and Kazakhstan

The article describes the world's experience in developing the solar industry. It discusses the mechanisms of state support for developing renewable energy sources in the cases of five countries that are the most successful in this area—China, the United States, Japan, India, and Germany. Furthermore, it contains a brief review of state policy in producing electricity by renewable energy facilities in Kazakhstan. This paper uses statistical information from the International Renewable Energy Agency (IRENA), the International Energy Agency (IEA), British Petroleum (BP), and the Renewable Energy Network (REN21), and peer-reviewed sources. The research methodology includes analytical research and evaluation methods to examine the current state of solar energy policy, its motivators and incentives, as well as the prospects for its development in Kazakhstan and in the world. Research shows that solar energy has a huge development potential worldwide and is sure to take its place in gross electricity production. This paper focuses on the selected economic policies of the top five countries and Kazakhstan, in what may be considered a specific research limitation. Future research suggestions for the expansion of Renewable Energy (RE) in Kazakhstan could include analysing the impact of introducing dedicated policies and incentives for solar systems and exploring the benefits and challenges of implementing large RE zones with government–business collaboration.

Green growth, sustainability, and decoupling carbon emissions from industrial activities in emerging economies: A focus on Zambia's energy sector

This paper quantified carbon emissions to create a credible post-COVID-19 baseline specific to the energy sector in Zambia. The approach was drawn from the IPCC – 2006 Guidelines for Tier 1. Using the IPCC Inventory Software V2.69, and focussing on specific sectors for which data were available, CO2 emissions were estimated from both petroleum-based fuel consumption, and electricity generation and consumption for the period 2019–2020. The spatial emissions consumption pattern for petroleum-derived fuels were also ascertained. From petroleum-based consumption, results show that the transport sector contributed 49% of the total CO2e emissions in the period examined, followed by mining at 28%, and power generation at 23%. Similarly, the spatial consumption emission-pattern revealed that Lusaka and Copperbelt Provinces were the highest emitters at 33 and 32%, respectively. It was concluded that CO2 emissions from petroleum-derived fuel consumption vary across the country and sectors. Results also showed that electricity generation and consumption contributed emissions 3-times more than petroleum-derived fuels with discounted importation of electricity, but 5-times more when importation of electricity was accounted. The mining sector was the highest emitter in the electricity consumption category.

Building a green future: Examining the job creation potential of electricity, heating, and storage in low-carbon buildings

Job creation is paramount when considering global transitions to low-carbon, clean-energy solutions. The building sector, critical to reducing greenhouse gas emissions on a global scale, has technologies available that rely on electricity rather than fossil fuels for energy and indoor heating and cooling. Solar photovoltaic, energy storage in the form of prosumer batteries, and heat pumps represent three readily deployable solutions to reduce carbon emissions in both new and retrofitted buildings. This study investigates the creation of jobs for each solution and then for all three combined across key countries in North America, Europe, and Asia. While other studies have explored aggregated job creation within nations, regions or globally, this first-of-a-kind study employs a micro-level approach examining six individual building archetypes: residential, hospital, hotel, office, retail, and education. Using the best available data as of 2022, the first-order assessment finds that more than 2 million new jobs and more than 141 million job years can be generated in Europe and the United States alone during the transition to net zero living.

Valorization of hazardous plastic wastes into value-added resources by catalytic pyrolysis-gasification: A review of techno-economic analysis

Plastic waste pollution has grown exponentially since the 1950s. This situation was exacerbated when the volume of personal protective equipment (PPE)-based plastic waste surged after the COVID-19 pandemic. Plastic waste management such as landfills and incineration have adverse effects on the environment and human health due to the leaching of hazardous chemicals and the emission of toxic gases. Modern solutions such as biodegradable plastics and green brick technology are expensive and not well developed to valorize the current accumulation of plastic waste. This has led to the emergence of thermal degradation processes, which is faster and more realistic to solve the PPE-based plastic waste buildup. Pyrolysis and gasification systems to valorize plastic waste into hydrocarbons and fuels are discussed and compared with examples respectively. Scoping review approach is employed to conduct this study. To further increase the value of the final product of plastic waste management, the integrated pyrolysis system to upcycle plastic waste to carbon nanomaterials (CNMs) and the factors affecting the production of non-condensable gases are critically reviewed. The importance of feedstock composition, catalyst type, pyrolysis operating condition (including gas condition and temperature profiles) based on various studies is discussed. The potential and limitation of an integrated pyrolysis system are assessed from kinetic analysis, economic analysis and life-cycle assessment. This review is expected to contribute to the industrial-scale development of sustainable upcycling of plastic waste and enhance the production of desirable gas components for CNM synthesis for environmental sustainability.

Health gains from home energy efficiency measures: The missing evidence in the UK net-zero policy debate.

Objectives: This study examined the health gains from a programme of external wall insulation works to homes in south-west Scotland, and in particular the impact upon hospitalisations for respiratory and cardiovascular conditions. Furthermore, to consider how evidence on health outcomes could form part of the debate around actions to meet net-zero goals in the UK. Study design: This was a two-part study. Part one involved before-and-after interviews with 229 recipient households. The second part comprised an observational study of hospital admissions in 184 postcode areas. Methods: Across three years, interviews collected thermal comfort and self-reported health data(Sf-36) in the winter months prior to installation, and again in follow-up interviews the next winter. Standarised monthly data on non-elective admissions for each set of conditions were compared between the intervention postcodes and the wider health board area over a ten year period. Results: Following receipt of wall insulation, inability to achieve thermal comfort in winter reduced by two-thirds. Improvements in thermal comfort were associated with gains in physical health scores. Relative standardised admissions fell in the treatment areas, remaining lower than the district-wide standardised rate for the majority of a five year period, this effect ending during the Covid-19 pandemic. The impact on admissions was greater for respiratory conditions than for cardiovascular conditions. Conclusion: A weak policy commitment to energy efficiency could be strengthened with further evidence of the cost-savings and reduced hospital bed demand resulting from insulations works. The potential health gain may also encourage more home owners to participate.

Solar Energy in Jordan: Investigating Challenges and Opportunities of Using Domestic Solar Energy Systems

With the recent global increase in fossil energy prices post Covid-19 and the drive to enhance sustainability towards NetZero, renewable energy is becoming one of the key global technologies to power societies at an affordable cost. This paper presents a novel study in relation to solar energy use in residential dwellings in Jordan, to discuss the benefits and challenges of using domestic solar energy systems within the current context of increasing energy prices. The Self-Determination Theory and Maslow's Hierarchical Theory are discussed in-line with the findings. This study, in addition to literature review, has utilised qualitative and quantitative data collected from an on-line survey with 366 participants to investigate Jordanian consumers' energy consumption behaviour, perception of renewables, and major factors influencing solar energy adoption. The novelty of this study that it provides a bench mark of affordability for future initiatives. The Jordan Renewable Energy & Energy Efficiency Fund is currently creating several initiatives to drive the society to adopt renewable energy. The results of this study will help to identify the crucial factors that could be hindering the adoption and expansion of renewables, particularly solar energy. This work has investigated awareness, motivation, difficulties, affordability and level of satisfaction in relation to solar energy in domestic dwellings. The results of this study have shown that Jordanians believe that financial affordability and awareness are both crucial for utilising renewables. For current users of solar systems, there is an increased satisfaction in their performance levels. However, energy storage is critical for enhancing the implementation of solar energy due to the complexity of grid-connected systems and the need for off-grid installations. Therefore, if renewable energy providers and governmental bodies aim to expand the implementation of solar energy technology and enhance public engagement, then it can be suggested that they should expand the promotion process of solar energy through platforms and further initiatives that engage with the public and subsidise the cost to provide more affordable solar energy systems for residential dwellings. The aim is to decrease carbon emission, reduce energy cost and enhance sustainability towards Net Zero Carbon emission.

Sustainability in orthodontics: Challenges and opportunities for improving our environmental impact.

OBJECTIVE: To highlight the potential environmental impact of different aspects of orthodontic care in the United Kingdom, outline the major barriers and challenges to reducing this impact, and summarise the possible action that could help the orthodontic community to tackle the climate change crisis. IMPACT: Travel, procurement and supply, material use, waste management, energy use and water consumption within dentistry have a considerable effect on the environment. There are, however, marked knowledge gaps pertaining to the impact of orthodontic treatment. CHALLENGES: The lack of awareness of the NHS contribution to the carbon footprint and net-zero goals among healthcare workers, the NHS backlogs and budget cuts, and cross-infection control requirements particularly following the COVID-19 pandemic are some of the many challenges to making healthcare delivery more sustainable. OPPORTUNITIES: By considering the triple bottom line (social, environmental and economic), incorporating the four Rs (Reduce, Reuse, Recycle, Rethink), taking practical action, including steps to educate ourselves and the wider team, and to promote research on environmental sustainability, we can get one step closer to reaching the NHS net-zero goals. CONCLUSION: Climate change is a global health threat with multiple contributors associated with orthodontic treatment delivery, which can be tackled on an individual, organisational and system level.

Predicting Energy Consumption in Residential Buildings Using Advanced Machine Learning Algorithms

The share of residential building energy consumption in global energy consumption has rapidly increased after the COVID-19 crisis. The accurate prediction of energy consumption under different indoor and outdoor conditions is an essential step towards improving energy efficiency and reducing carbon footprints in the residential building sector. In this paper, a PSO-optimized random forest classification algorithm is proposed to identify the most important factors contributing to residential heating energy consumption. A self-organizing map (SOM) approach is applied for feature dimensionality reduction, and an ensemble classification model based on the stacking method is trained on the dimensionality-reduced data. The results show that the stacking model outperforms the other models with an accuracy of 95.4% in energy consumption prediction. Finally, a causal inference method is introduced in addition to Shapley Additive Explanation (SHAP) to explore and analyze the factors influencing energy consumption. A clear causal relationship between water pipe temperature changes, air temperature, and building energy consumption is found, compensating for the neglect of temperature in the SHAP analysis. The findings of this research can help residential building owners/managers make more informed decisions around the selection of efficient heating management systems to save on energy bills.

DESIGN OF A NET ZERO HOUSE AT 100-YEAR FLOOD ZONE IN A HISTORIC DISTRICT: A CASE OF SOLAR DECATHLON DESIGN CHALLENGE ENTRY

This paper discusses the design of a net-zero single-family house in Chattanooga, Tennessee, which was proposed for the 2022 Solar Decathlon Design Challenge entry. The site was in a 100-year flood zone and registered as a national and local historic district. The interdisciplinary team consisted of University of Tennessee Chattanooga (UTC) students from the interior architecture and engineering departments who embraced the challenges of the local climate and the restrictions of the historic district guidelines. This entry, Moc House, focused on the integration of passive design and active HVAC systems including photovoltaic systems in the process. In responding to recent housing market changes in Chattanooga due to the COVID-19 pandemic, a young professional couple in their 30s who have two children was identified as the target market which guided the space planning. Market analysis, including ROI, was conducted in addition to construction cost calculations. Building materials were selected to enhance the durability and resilience of the house structure. Finally, energy analysis was conducted to check the project's Home Energy Rating using Ekotrope and found it less than zero. © 2023, College Publishing. All rights reserved.

An Evaluation of ASEAN Renewable Energy Path to Carbon Neutrality

Maintaining our standard of living and keeping the economy running smoothly is heavily reliant on a consistent supply of energy. Renewable energy systems create abundant energy by utilizing resources such as the sun, wind, earth, and plants. The demand for renewable energy is increasing, despite power scarcity, pollution, and climate change posing challenges to long-term development in the Association of Southeast Asian Nations (ASEAN), which has seen significant social and economic growth in recent years. To achieve its 23% renewable energy (RE) target, ASEAN can develop solar photovoltaic (PV) electricity. Members of the ASEAN have established regulations and incentives to encourage individuals and businesses to use renewable energy in the future. This paper explores Southeast Asian countries' comprehensive fossil-free energy options, the region's renewable energy potential, current capacity, goals, and energy needs. Through the ASEAN Plan of Action for Energy Cooperation (APAEC) 2016–2025 and the ASEAN Declaration on Renewable Energy, ASEAN is committed to reducing its greenhouse gas emissions and promoting sustainable development aligning with the Paris Agreement's aim to limit global warming to well below 2 degrees Celsius above pre-industrial levels. Results show that decarbonizing the region's energy system is possible, but current policies and actions must be altered to reach that target level. Further research is necessary to optimize the ASEAN region's renewable resource technical potential and commercial viability with available technology.

A critique on the UK's net zero strategy

Before the Covid-19 pandemic UK passed net-zero emission law legislation to become the first major economy in the world to end its contribution to global warming by 2050. Following the UK's legislation to reach net-zero emissions, a long-term strategy for transition to a net-zero target was published in 2021. The strategy is a technology-led and with a top-down approach. The intention is to reach the target over the next three decades. The document targets seven sectors to reduce emissions and include a wide range of policies and innovations for decarbonization. This paper aims to accomplish a much needed review of the strategy in heat and buildings part and cover the key related areas in future buildings standard, heat pumps and use of hydrogen as elaborated in the strategy. For that purpose, this research reviews key themes in the policy, challenges, recent advancement and future possibilities. It provides an insight on the overall development toward sustainability and decarbonization of built environment in the UK by 2050. A foresight model, Future Wheels is also used to visualize the findings from the review and provide a clear picture of the potential impact of the policy. © 2023

'Building back better' or sustaining the unsustainable? The climate impacts of Bank of England QE in the Covid-19 pandemic.

The environmental impacts of monetary policy received academic attention after the 2008 financial crisis and the 'market neutral' quantitative easing policies that followed. This article examines the Bank of England's Corporate Covid Financing Facility (CCFF) and the Asset Purchasing Facility (APF) between June 2020 and June 2021 to assess whether the Bank's response to the COVID-19 pandemic was aligned with the transition to sustainability. The data indicates that the Bank of England's monetary allocation schemes again served as a panacea for businesses with ecologically intensive business models and a Treasury committed to restoring the pre-existing growth model. Indeed, the Bank's QE schemes now represents an element of the crisis management governance that repeatedly 'locks in' the ecologically-calamitous economic trajectory at potential critical junctures. The Bank's shielding of its technocratic and depoliticised status has thus far inhibited any leadership role in tackling the climate crisis, despite its growing power as an actor of economic governance at times of crisis and purported enthusiasm to 'build back better'.

Typology-wise Residential Energy Benchmarking and Net ZEB Potential: A Case Study of Residential Complexes inside IIT Kharagpur, India

Rapid urbanization in developing countries has come at great costs in terms of the increasing energy demand. As India is a developing nation, the rising per capita income, and increasing purchasing power of domestic alliances by households, are pushing the household energy demand to rise sharply. Thus, there is a need to move towards the implementation of Net-Zero buildings in the residential sector in India to curb the escalating trend of energy demand. Although Rooftop Solar Photovoltaic has gained attention as a sustainable energy alternative to conventional sources, the potential of façade solar PV for harnessing alternative energy sources remains unexplored. This study aims to design and assess the feasibility of a grid-connected façade solar PV to meet the energy demand of residential complexes in a residential academic campus in India. Three groups of residential complexes based on energy-related user behaviour and built area have been identified in the study. Further, the maximum energy demand recorded in CoVID-affected years has been considered for designing the PV system. The study demonstrates that Façade Solar PV can solely meet 77-82% of the maximum energy demand of each group, and meets the Net-Zero potential for the studied residential typologies. Furthermore, it has been found, that the current residential benchmarking and labeling by the Bureau of Energy Efficiency (BEE), are largely climate-based and do not correspond with housing typology and built area. Thus, this study proposes a novel energy benchmarking and labelling system, based on the studied housing typology and corresponding energy usage, expressed in terms of the Energy Performance Index (EPI). It is found that the proposed energy efficiency labels for different typologies vary from the existing BEE residential benchmarking labels in terms of the calculated EPI and corresponding star rating when considered for Warm and Humid climatic zone. © 2022 ACM.

Virtual Arthroplasty Follow-Up: Better for the Trust, Patients, and the Planet.

Background The Virtual Arthroplasty Follow-Up (VARF) Quality Improvement Project was initiated in March 2020 with the aim of improving patient experience while reducing costs to the trust, the patient, and the planet. Methodology This retrospective study was conducted in a district general hospital. Patients were assessed based on their Oxford Hip Score (OHS), University of California, Los Angeles (UCLA) activity score, and an X-ray. A patient satisfaction survey was undertaken via phone call using a 10-point questionnaire. These responses were then correlated to age, distance travelled, and OHS/UCLA scores. The environmental impact was estimated using CO2 emissions for driving and outpatient clinics taken from relevant literature. Results A total of 132 patients were enrolled in the project. Overall, 75% demonstrated a good outcome from both their X-ray and OHS/UCLA scores. Further, 23% of patients required an additional phone call, of which a further 77% were re-enrolled in the VARF pathway. Only five of 132 (3.8%) patients required a face-to-face review. The patient satisfaction survey enrolled 52 patients, 90% of whom were satisfied with the service. Only one patient stated being dissatisfied with the service. Overall, 77% of patients felt that the service saved them time, money, or both. The strongest predictor of patient satisfaction was the OHS (r = 0.52) where a score of <35 was associated with a nine-fold increase in either responding neutral or dissatisfied with the service. Accounting for both travel and clinic space, approximately 8 tonnes of CO2 equivalent were saved. Once time and cost-saving from virtual clinics were included, this project saved the trust £21,408 and patients £948. Conclusions VARF has been shown to be an appropriate way to follow up arthroplasty patients which maintains high patient satisfaction while reducing the environmental impact, saving patients' time and money, and freeing up clinic space for other uses. A potential improvement of the process would be to triage those with low OHS to a more intensive follow-up.

Exploring IoT Applications for Vertical Transportation (VT) to Tackle Challenges in a Modern World

This paper investigates and proposes applications for emerging, off-the-shelf technologies for vertical transportation (VT) equipment, with a view to tackling some of the changes in social, economic, and environmental requirements of key stakeholders for buildings. Covid-19 has presented opportunities for IoT technologies to be used within VT systems, to measure air quality and maintain the peace of mind of tenants returning to the office. Sensors have been used to measure a range of in-car, air quality metrics, the analysis of which will be used to recognise how devices can provide stakeholders with accessible, transparent information of the environment in their lifts. With a drive for energy efficiency, and clients striving to meet their net-zero targets, IoT devices can also be used to monitor energy usage of VT equipment and make strategic decisions to save energy and reduce carbon emissions. This paper also looks to understand if, and how we can measure power used by VT systems with these devices. This, coupled with understanding the changing habits of the average office worker, can be used to think out of the box regarding efficient operation of buildings. The author's previous research investigated the use of IoT technology to monitor the condition of lifts. Analysis of breakdown data and interviews with key stakeholders were used to demonstrate how this technology could be used for earlier fault diagnosis. Since the original study, the industry has moved forwards with off-the-shelf and third party IoT systems being trialled by clients and independent suppliers, to support maintenance and repair strategies. Previously, this was only possible with major lift maintenance companies. © 2022, Lift and Escalator Symposium Educational Trust. All rights reserved.

Economic and Environmental Impact of Digital Health App Video Consultations in Follow-up Care for Patients in Orthopedic and Trauma Surgery in Germany: Randomized Controlled Trial.

BACKGROUND: Following the Riyadh Declaration, digital health technologies were prioritized in many countries to address the challenges of the COVID-19 pandemic. Digital health apps for telemedicine and video consultations help reduce potential disease spread in routine health care, including follow-up care in orthopedic and trauma surgery. In addition to the satisfaction, efficiency, and safety of telemedicine, its economic and environmental effects are highly relevant to decision makers, particularly for the goal of reaching carbon neutrality of health care systems. OBJECTIVE: This study aims to provide the first comprehensive health economic and environmental analysis of video consultations in follow-up care after knee and shoulder interventions in an orthopedic and trauma surgery department of a German university hospital. The analysis is conducted from a societal perspective. We analyze both economic and environmental impacts of video consultations, taking into account the goal of carbon neutrality for the German health care system by 2030. METHODS: We conducted a prospective randomized controlled trial comparing follow-up care with digital health app video consultations (intervention group) to conventional face-to-face consultations in the clinic (control group). Economic impact included the analysis of travel and time costs and production losses. Examination of the environmental impact comprised the emissions of greenhouse gases, carbon monoxide, volatile hydrocarbons, nitrogen oxides, and particulates, and the calculation of environmental costs. Sensitivity analysis included calculations with a higher cost per ton of carbon dioxide equivalent, which gives equal weight to the welfare of present and future generations. RESULTS: Data from 52 patients indicated that, from the patients' point of view, telemedicine helped reduce travel costs, time costs, and production losses, resulting in mean cost savings of €76.52 per video consultation. In addition, emissions of 11.248 kg of greenhouse gases, 0.070 kg of carbon monoxide, 0.011 kg of volatile hydrocarbons, 0.028 kg of nitrogen oxides, and 0.0004 kg of particulates could be saved per patient through avoided travel. This resulted in savings of environmental costs between €3.73 and €9.53 per patient. CONCLUSIONS: We presented the first comprehensive analysis of economic and environmental effects of telemedicine in the follow-up care of patients in orthopedic and trauma surgery in Germany. Video consultations were found to reduce the environmental footprint of follow-up care; saved travel costs, travel time, and time costs for patients; and helped to lower production losses. Our findings can support the decision-making on the use of digital health during and beyond the COVID-19 pandemic, providing decision makers with data for both economic and environmental effects. Thanks to the pragmatic design of our study, our findings can be applied to a wide range of clinical contexts and potential digital health applications that substitute outpatient hospital visits with video consultations.

Greening aviation in era of COVID-19: Towards conceptualizing and operationalizing decarbonization.

Although net-zero greenhouse gas emission targets continue to gather burgeoning streams of research, there is a lacuna in current literature on the pathway challenges towards operationalizing decarbonization. The study advanced 2 × 2 matrix of an organizing framework of challenges in accomplishing net-zero emissions targets. Using the global airline industry as an illustrative context, the study provided deep insights on the pivotal industry, institutional, and organizational challenges in the era of COVID-19 such as fleet modernization, over-reliance on fossil fuel, slow progress in the development of hydrogen and electric aircraft, risk of corporate greenwashing, and divergent approaches adopted by airlines. The challenges can be classified into policy-oriented, organization-specific, and external/macro-environment factors. The contributions to theory and practices were identified and examined.

On the Road to Net Zero Health Care Systems: Governance for Sustainable Health Care in the United Kingdom and Germany.

Health care lies at the forefront of the impacts of climate change. Since the health sector is a major polluting and emission intensive sector, it remains a crucial challenge to address sustainability. The English National Health System (NHS) aims to be the first in the world to achieve net zero in all emission classes (Scope 1-3). In Germany, sustainability in health care is being driven bottom-up, while the Federal Ministry of Health at the time of the research in early 2021 takes no active stance on a net zero health care system. This article analyses the approaches to sustainability in the two different health care systems, explores common challenges, and draws recommendations to support the transition of the sector to a net zero future. An exploratory mixed method approach was taken applying qualitative and quantitative methods. This includes high-level expert interviews and an online survey from the United Kingdom (UK) and Germany. Results reveal the complex nature of health care systems and the need for engraining a systems-thinking approach. The findings call for the legal embedding of sustainability into the key principles of health care in Germany, endorses the ambition of the national health care systems in the UK, recommends collaborative cross-sector approaches for sustainability, and highlights the need for increased public awareness on the interrelation between human and planetary health to enable governance for sustainable health care.

Financial firm’s performance: a comparative analysis based on ESG metrics and net zero legislation

For stock market investors, it is difficult to choose where to allocate their financial resources;furthermore, sustainable investment has become a choice to ensure better financial performance (FP). This research proves that countries and companies lined up with climate change laws are better options for investing and mitigating risks. The sample of the study is based on a net zero emission criteria, so six countries were identified with approved legislation, and a comparison between the largest market cap firms of these countries and the largest market cap of the world (Benchmark) is made to analyze their FP during the COVID-19 first year. Furthermore, regression models were run to review which ESG factor is the most related to predicting the ESG combined score for the firms. The results show that the firms had a better performance than the Benchmark and that the social factor 'S' is the most correlated to the ESG combined score. The relevance of this article lies with the relevance of investing in companies aligned with net zero emissions laws since they contribute to improving the expected return even in a volatile era.
