ABSTRACT

According to the European Parliament, the EU is facing a major energy crisis, triggered on the one hand by natural gas shortages and on the other by the explosive rise in energy prices. In this context, the aim of this paper is to identify the requirements of the final energy consumer and the opinions on energy produced from renewable sources (E-RES) and to analyze the factors influencing investments in E-RES. In order to achieve the proposed goal, the following objectives were formulated: objective 1 - review of the literature on investments in renewable energy;objective 2 - to establish the implications generated by the Russian-Ukrainian conflict on the activity of the energy sector;objective 3 - evaluation of the contribution of green certificates (CV) in stimulating the production of green energy;objective 4 - identify the end consumer's perspective on the transition from conventional to renewable energy sources.

ABSTRACT

With rising electricity demand, heavy reliance on imports, and recent economic downturns due to the negative impact of the COVID-19 pandemic, supply chain bottlenecks, and the Russian invasion of Ukraine, Thailand is suffering severely from energy resilience risks. The government has therefore set a goal of decentralizing energy production through small-scale distributed renewable energy systems. To support their design and the planning process, we simulate multiple scenarios with wind turbines, photovoltaic systems, and battery storage for a model community in rural Nakhon Phanom, Thailand. Using the software NESSI4D, we evaluate and discuss their impact on energy resilience by considering environmental sustainability, economic attractiveness, and independence from the central power grid. To fill the gap of missing data on energy demand, we synthesize high-resolution load profiles from the Thailand Vietnam Socio-Economic Panel. We conclude that distributed photovoltaic systems with additional battery storage are only suitable to promote energy resilience if the government provides appropriate financial incentives. Considering temporal variations and local conditions, as well as a participatory decision-making process, are crucial for the long-term success of energy projects. Our advice to decision-makers is to design policies and regulatory support that are aligned with the preferences and needs of target communities.

ABSTRACT

The aim of this article is to show the impact of the COVID-19 pandemic on electricity consumption and, consequently, on decisions regarding the installation of photovoltaic panels using the example of a selected local authority in Poland—the Szemud Municipality. The analysis was conducted in 2022 and covered the years 2019–2021. An attempt was made to explore the factors that may have triggered an increase in the use of solar energy in households and identify the determinants of installing photovoltaic panels in the period under analysis. Previous analyses of the PV market (and the impact of the pandemic on it) have so far focused on the market as a whole, either in macro or global terms, while studies on smaller municipalities have been limited to examining changes in electricity consumption levels during the COVID-19 pandemic and during lockdown. Therefore, a research gap was identified in that there are no studies analyzing the reasons for the shift from conventional to PV-assisted energy in households, with the COVID-19 pandemic as the background of these changes. The literature research showed that there are currently no studies attempting to establish a link between the increased interest in this type of energy by local authorities and the COVID-19 pandemic. The research confirmed the hypothesis of increased interest in household PV during the pandemic. The main conclusions of the study boil down to the need for further support as well as promotion of the use of solar energy. In addition, the results derived from the empirical research indicate the need to take action at a policy level to counter adverse trends regarding undesirable social behavior.

ABSTRACT

Since the emergence of the COVID-19 pandemic, people all around the globe have seen its effects, including city closures, travel restrictions, and stringent security measures. However, the effects of the COVID-19 pandemic extend beyond people’s everyday lives. It impacts the air, water, soil, and carbon emissions as well. This article examines the effect of energy and the COVID-19 pandemic on China’s carbon dioxide emissions in light of the aforementioned context, using the daily data from 20 January 2020 and ending on 20 April 2022. Using the nonlinear autoregressive distributed lag model for empirical analysis, the findings indicate that COVID-19 pandemic confirmed cases and renewable energy advance environmental sustainability due to their negative effects on carbon dioxide emissions, whereas fossil fuel energy hinders environmental sustainability due to its positive effect on carbon dioxide emissions. Moreover, these results are also supported by the results of the frequency domain causality test and the Markow switching regression. In light of these results, there are several policy implications, such as vaccination, renewable energy utilization, and non-renewable energy alternative policies, which have been proposed in this paper.

ABSTRACT

The devastating social, economic and mental disruption caused due to pandemic has forced the decisionmakers to rewrite the script and opens up a way for transformative resilience, green and more digitally enabled strategies and recovery leading to a next wave of economic prosperity. Prior to the pandemic, many recognized the need for a new economic model that is less environmentally damaging, not much dependent on the globalized linear supply chain, cheap raw material and is less wasteful. Post pandemic crisis calls for a need to transition to a new thinking, resilience, and sustainable and circular way of doing business in alignment with other global challenges. In this reference, this study provides an insight into what resilient circular economy strategies looks like post Covid-19. Also, the study highlights the Challenges and opportunities created by resilient circular economy (CE) towards a sustainable business model. For this purpose, a semi- structured interviews are conducted with 23 executives across industries on resilience and CE. The study concludes that the transition from old linear model to a new closed loop model is not as easy as it looks like, it requires a thoughtful collaboration, creating synergies between the systems, participation, resilience mindset (which involves rethinking, redefining, and reinventing our priorities, resources, skills), political momentum, connectivity, diversity and most importantly systems thinking. Study is conceptual and qualitative in nature. Analysis of interviews together with the literature forms the basis of the research study. The study suggest that the circular economy must embed a strong sociological basis to manage both slow social variables such as company culture, employee’s mindset, human capital, worker habit and feedbacks.

ABSTRACT

In this study, the use of Twitter for public relations purposes of the Lahti municipality was analysed. The study aims to reveal the public relations focus of the ecological municipality approach. In this context, Tweets shared on the Twitter account of the municipality between November 1 and November 30, 2021, were analysed by discourse and content analysis method in the 2020.2.2 version of the Maxqda program. The findings obtained from the analysis are: In the process that Lahti was elected as an ecological municipality, it shared the most on municipal services and ecological city. The main topics shared by the municipality were identified as Covid-19, Lahti activism, ecological city, and municipal services. The main headings of the macro discourse of this process, which covers municipal services;Lahti City is urban transportation, openings, tender announcements, meetings, cooperation, and events. When these discourse titles are analysed at the micro-level, it is seen that a simple, active, and everyday language is used. When the shares are examined in rhetoric, reference representation is quite intense in persuasiveness. As a result;It is seen that the municipality of Lahti fulfills the principles of corporate citizenship on Twitter, which it uses for recognition and promotion purposes.

ABSTRACT

For many decades, the Region of Western Macedonia has been Greece’s energy hub, contributing significantly to electricity supply and national growth with the exploitation of lignite deposits for power generation. Lignite, though, has been banned from EU energy source policies towards achieving CO2 emissions reduction, with profound implications on the economy of the region. Despite the importance of this energy transition, a combinatorial analysis for the area in the coal phase-out regime is missing. Therefore, a combined analysis is performed here, and more specifically, a strengths, weaknesses, opportunities, and threats (SWOT) analysis in all the affected sectors, in combination with the examination of the degree of satisfaction with the EU’s energy priorities. The results of the study show that the Region of Western Macedonia has profound strengths and offers many new opportunities during its transition to a new production model. On the other hand, it has high unemployment rates and low rates of competitiveness and innovation. The main threat is the Region’s desertification due to the inability to find sufficient jobs. Considering the Energy Union’s priorities, the Region of Western Macedonia satisfactorily follows the priorities of Europe in its transition to the new production model, with plenty of room for improvement. The analysis performed allows for a just transition strategic planning to minimize social, economic and energy challenges while maximizing sustainable power generation and has implications for all relevant stakeholders, contributing to the implementation of Energy Union governance and climate actions.

ABSTRACT

The recent inclusion of shipping in the Fit for 55 legislation package will have large knock-on effects on the industry and consequently on end consumers. The present paper presents an innovative top-down methodology, the MSF455 model, which estimates the new vessel Operational Expenditure (OPEX) as per the provisions of the Fit for 55 package and various scenarios based on carbon tax, penalty allowances, maritime fuel tax and effect. The methodology is presented and tested against six scenarios that are based on Det Norske Veritas’s (DNV) fuel maritime projections. The model illustrates that the distinction between intra-EU and extra-EU penalty allowance creates a large disparity and thus reduction in the competitiveness of goods (produced and transported).

ABSTRACT

In recent years, one of the key postulates in the European Union’s policy has become the development of renewable energy sources. In order to achieve the desired synergy effect, the idea of combining two selected sources of energy appeared. This article presents a technical and economic analysis of a hybrid connection of a ground source heat pump with a photovoltaic installation. Taking into account the heat demand of the building, a ground heat pump with a catalog nominal heating power of 25 kW was selected. This article presents the problem of the economic profitability of using a hybrid combination of a heat pump and photovoltaic panels in domestic hot water and central heating systems. The justification for the use of such heat sources in these installations is due to global trends and the gradual departure from conventional energy sources such as oil or gas boilers. This paper presents the economic and ecological results of using the pump heat connected together with photovoltaic panels. In the economic analysis, with the assumed installation costs related to the use of the considered heat pump and PV, two parameters commonly used in the investment analysis (static and dynamic) were used, namely, the simple payback period and the net present value of the investment. For the adopted assumptions, the usable area of the facility and the number of years of use were indicated, at which the investment in question is competitive with other alternative investment interest methods and will start to bring tangible benefits. The performed analysis also has measurable environmental benefits in the form of a reduction in carbon dioxide emissions at the level of 2893 kg/year into the atmosphere. The presented solution will help future investors understand the investment profitability mechanism for their households.

ABSTRACT

Solar and wind power systems have been prime solutions to the challenges centered on reliable power supply, sustainability, and energy costs for several years. However, there are still various challenges in these renewable industries, especially regarding limited peak periods. Solar–wind hybrid technology introduced to mitigate these setbacks has significant drawbacks and suffers from low adoption rates in many geographies. Hence, it is essential to investigate the challenges faced with these technologies and analyze the viable solutions proposed. This work examined solar–wind hybrid plants’ economic and technical opportunities and challenges. In the present work, the pressing challenges solar–wind hybrids face were detailed through extensive case studies, the case study of enabling policies in India, and overproduction in Germany. Presently, the principal challenges of solar–wind hybrids are overproduction, enabling policies, and electricity storage. This review highlights specific, viable, proposed solutions to these problems. As already recorded in the literature, it was discovered that academic research in this space focuses majorly on the techno-economic and seemingly theoretical aspects of these hybrid systems. In contrast, reports and publications from original equipment manufacturers (OEMs) and engineering, procurement, and construction engineers (EPCs) are more rounded, featuring real-life application and implementation.

ABSTRACT

If global energy consumption returns to its pre-pandemic growth rate, it will be almost impossible to transition to a zero-emission or net-zero-emission energy system by 2050 in the absence of large-scale CO2 removal. Since relying on unproven technologies for CO2 removal is speculative and risky, this paper considers an energy descent scenario for reaching zero greenhouse gas emissions from energy by 2050. To drive the rapid transition from fossil fuels to carbon-free energy sources and ensure demand reduction, funding is needed urgently in order to implement four strategies: (i) technology change, i.e., implementing the growth of zero-carbon energy production, end-use energy efficiency and ‘green’ energy carriers, together with ongoing R&D on CO2 removal;(ii) reducing climate impacts;(iii) reducing energy consumption by social and behavioural changes;and (iv) improving human wellbeing while increasing social justice. Modern monetary theory explains how monetary sovereign governments, with their own fiat currencies, can create the necessary funding without financial constraints, although constraints do result from the productive capacities of their economies. The energy transition could be part-funded by a significant transfer of resources from monetary sovereign countries of the global North to the global South, financed by currency issuance.

ABSTRACT

The study concerns the preparation of post-consumer food packaging for selective collection that takes place in households. The previously reported results suggested that the economic cost of washing the packaging exceeded the value of recyclable materials. A shortage of up-to-date papers on the economic balance of packaging washing, taking into account current trends in the increase of prices of materials and energy carriers, has been identified. The main objective of this study was to determine the effect of the application of particular heat sources on the total cost of preparing the glass and plastic packaging for selective collection, as well as to compare the cost with the economic value of recyclables. Over the last ten years, a drop in the purchase price of glass cullet and post-consumer plastic, as well as an increase in the cost of cold and hot water, have been reported. Accordingly, the profit of packaging cleaning, defined as the difference between the value of recyclable materials and the cost of washing them, has decreased. The energy consumed for water heating was identified as the most relevant factor affecting the entire economic balance. Even assuming the most efficient water heating solutions, the pre-treatment of the post-consumer food packaging turned out to be unprofitable. The conclusion reached in the previously published study has been confirmed.

ABSTRACT

Natural gas is acting as a transitional fuel source as the world shifts toward fully renewable energy. Recently, Europe has confirmed this continued usage of natural gas, with the European Union voting in favor of calling natural gas a "green" or "sustainable" source of energy despite some pushback. However, there is one caveat: a further transition toward biogas or green hydrogen and other renewable gases by 2035. This is a good sign that natural gas power generation units will have a solid future in the energy mix of tomorrow.

ABSTRACT

[...]building operators follow the guidelines recommended by ASHRAE and the CDC to reduce infection risk from airborne viruses and improve cognitive function for building occupants by increasing the percentage of fresh air the ventilation system is circulating throughout the building. Sensors in lighting, HVAC equipment and managing temperature controls, and occupancy sensors that determine the demand for space and utilization provide actionable insights to offset energy cost increases by automation and improving the efficiency of managing space and energy consumption. Some of the practical consequences of what building owners and business owners are facing and need to consider in their business continuity and resiliency planning include: * Property & Casualty insurance costs will rise quickly, according to multiple studies;2 * Increased needs for energy resilience on-site (cleaner backup power, co-gen/battery) to ensure critical building functions continue to run and the business owner's critical operations are not impacted when the grid is down (sump pumps, elevators for evacuations, emergency lighting, HVAC);* An increased number of people working from home also increases demand for an unplanned increase in the residential demand for constant power and uptime.

ABSTRACT

Climate change is taking place on a global scale and it is substantially affected by human activity, including increasing greenhouse gas emissions. One of the thematic objectives of EU’s new financial objective is a more environmentally friendly low-emission Europe that promotes clean and fair energy transformation, green investments, and a circular economy, among others. The Polish economy is mainly based on energy production from conventional sources (fossil fuels). Considering that the demand for electricity in Poland is predicted to increase by as much as 50% until 2040, it is necessary to take action aimed at increasing the share of renewable energy sources. The subject of analysis is the Opolskie Voivodeship (a NUTS 2 type region), the capital of which features the biggest Polish coal power plant. In 2014–2019, it was expanded by two units with 1800 MW in total capacity, thereby indicating that investments in energy obtained from conventional sources are still implemented and to a large extent at that (the expansion has been the biggest infrastructural investment in Poland since 1989). The Opolskie region is characterised by substantial excess in acceptable environmental burden (dust pollution, among others). The aim of the paper is to evaluate the key environmental conditions for the Opolskie region’s development in terms of the assumptions of the domestic and EU energy policies. The Opolskie region’s developmental challenges in the environmental area were determined on the basis of selected indicator estimations up to 2030. The research hypothesis assumes that the environmental conditions for the Opolskie region’s development are unfavourable. The methodological part features an analysis of the cause and effect dependencies in the “environment” area, which enabled an assessment of the Opolskie Voivodeship’s current situation as well as an analysis of the dependencies relevant to the region’s development. This was followed by an estimation of selected indicators in the “environment” area until 2030, which allowed for an assessment of their probable levels and thereby a specification of the region’s development conditions. The estimation was conducted using the data available in public statistics, i.e., Statistics Poland’s data. The indicators estimated for 2030 were presented using three forecasting methods: (a) the monotonic trend, (b) the yearly average change rate, and (c) the logarithmic trend.
