This research was conducted to estimate the economic feasibility of establishing biogas plant from dairy farms manure in Al-Dlail district (Zarqa governorate). Biogas is a mixture of gas consisting of 50-70% of methane and carbon dioxide 30-45%, and other gases and water that resulted from the digestion of the biomass process with the absence of oxygen. It is used as a fuel source in many countries for the purposes of lighting and cooking. Biogas is a clean and renewable form of energy that can be sustainable solutions of large organic waste produced in animal farms and reduces the harmful environmental pollution. Also, it can be an opportunity to invest and make profits. Data for this research was collected by desk research, survey and interviews. The respondents were 31 dairy farmers; the interview included the Jordan Biogas plant manager, owners of manure plants, heads of cattle breeders associations and stakeholders in government organization. The collected data were analyzed by using SPSS, 5P's analysis, PESTEC Analysis and Canvas model to come up with a clear picture about the feasibility of biogas utilization in Zarqa governorate. The study showed the tremendous environmental pollution that happened in Al-Dlail and Al-Khaldiah areas due to the poor management of cattle farms manure, causing air, soil ground and surface water pollution. As a solution to this problem, the study showed that the most appropriate solution to this problem is to exploit these manure in the production of energy from biogas as a sustainable, and environment-friendly project. The research also included the size of the feedstock of the manure produced from cattle farms, the availability of the necessary technology to build a project of this plant, the availability of markets for its products and the legislative framework governing the renewable energy projects represented by the Ministry of Energy. The study concluded that it is possible to establish a medium-sized biogas plant. The recommendation is to facilitate government procedures for investors in renewable energy and the promotion of environmental awareness between farmers and pay more attention to the management of livestock waste by creation waste management departments in government institutions.

Indonesia policy in Presidential Regulation No. 5 of 2006 on National Energy Management 2006-2025 states that one of its tasks is the ethical and sustainable management of energy, including the maintenance of environmental functions and increasing the role of new and renewable energy to 5% by 2025. In response to this problem, an effort is needed to meet the Indonesian people's energy needs. One of the programs of the Indonesian government is the implementation of an energy-independent village program. Jimbaran Village is one of the villages that have the potential to develop into an Energy Independent Village. The majority of Jimbaran Village residents work as cattle breeders, i.e., 1,663 families. The average farmer in Jimbaran Village has 3-4 cows/family heads with a total of 5,976 dairy cows. However, of the many existing breeders, no one has processed cow waste into biogas, which is a source of renewable energy. Animal waste may also be used to develop the clove and coffee plantation sector when processed into compost. Livestock waste is only dumped into sewers or human yards, so the environment is very polluting. It is, therefore, necessary to process livestock waste into biogas or compost. The analysis technique used in calculating the plan for the production of communal biogas is the analysis of supply, demand, and energy performance. Based on the calculation of the energy performance, it can be seen that the energy performance is more than 100 percent, which means that there is an excess of energy generated by existing biogas. Excessive energy can be allocated to other energy needs, such as electricity so that people can convert their current source of electrical energy from PLN to biogas.

Renewable energy (RE) sources are often locally available and have the potential to lessen the rural dependence on the national power grid, reducing disruptions in power supplies and the heavy dependence on coal combustion. Poland faces an EU mandate of a 15% share of renewables in energy generation by 2020. However, the installations intended to supply several types of RE encountered local opposition, forcing a cancellation of the planned investments and stressing a need for understanding rural residents’ attitudes towards RE in general. Using survey data, this paper examines the perception of RE importance among rural residents in eastern Poland. The specified empirical relationship includes the sociodemographic and economic characteristics of residents. Perceptions of the links between health and specific sources of environmental pollution and actions demonstrating energy-saving behavior serve as explanatory variables. The performance of the estimated logit equation was rigorously tested. The probability of attaching importance to RE by rural residents increases most if a respondent displayed an energy-saving behavior, has certain demographic characteristics, and links health to environmental pollution caused by coal combustion. The graphic depiction of the effects of selected variables succinctly communicates possible future programs aimed at strengthening the rural population support of RE.

Sustainability has been greatly impacted by the reality of budgets and available resources as a targeted range of carbon emission reduction greatly increases due to climate change. This study analyses the technical and economic feasibility for three types of solar photovoltaic (PV) renewable energy (RE) systems; (i) solar stand-alone, a non-grid-connected building rooftop-mounted structure, (ii) solar rooftop, a grid-connected building rooftop-mounted structure, (iii) solar farm, a grid-connected land-mounted structure in three tropical climate regions. Technical scientific and economic tools, including life cycle assessment (LCA) and life cycle cost assessment (LCCA) with an integrated framework from a Malaysian case study were applied to similar climatic regions, Thailand, and Indonesia. The short-term, future scaled-up scenario was defined using a proxy technology and estimated data. Environmental locations for this scenario were identified, the environmental impacts were compared, and the techno-economic output were analysed. The scope of this study is cradle-to-grave. Levelised cost of energy (LCOE) was greatly affected due to PV performance degradation rate, especially the critical shading issues for large-scale installations. Despite the land use impact, increased CO2 emissions accumulate over time with regard to energy mix of the country, which requires the need for long-term procurement of both carbon and investment return. With regards to profitably, grid-connected roof-mounted systems achieve the lowest LCOE as compared to other types of installation, ranging from 0.0491 USD/kWh to 0.0605 USD/kWh under a 6% discounted rate. A simple payback (SPB) time between 7–10 years on average depends on annual power generated by the system with estimated energy payback of 0.40–0.55 years for common polycrystalline photovoltaic technology. Thus, maintaining the whole system by ensuring a low degradation rate of 0.2% over a long period of time is essential to generate benefits for both investors and the environment. Emerging technologies are progressing at an exponential rate in order to fill the gap of establishing renewable energy as an attractive business plan. Life cycle assessment is considered an excellent tool to assess the environmental impact of renewable energy.

Agriculture Development

This article proposes a systematic engineering for sustainable economic and ecologic development. This system is deemed to be applicable in any country of the world. The system aims to realize five important objectives: water source clearance, energy saving and emission reduction, renewable energy and organic fertilizer production, and ecological agriculture development, all in large scale and at low cost. The main conception of the new system to reach these goals is the replacement of the conventional sewage treatment approach with more efficient and more ecological process – the natural fermentation of the mixture of the urban sewage and agrarian wastes, such that water body clearance, including water de-eutrophication, green algae prevention and siltation dredging will all be accomplished at virtually a zero cost. Along with this process, the system can produce a vast amount of renewable energy and organic fertilizers, consequently ecological agriculture development in large scale can be realized. As a result, this system will greatly reduce the use of chemical fertilizers thus largely reduce the consumption of fossil energy and the related polluting emissions. This system is thus fully a circular economy model through full west-reuse processes, which ultimately will enhance our life quality with healthier food and living environment. The system is flexible and adaptable to be implemented in either small towns or megacities. The implementation and operation of this system will also benefits employment growth. Lastly, in terms of economic feasibility and profitability, millions to billions of dollars of annual revenue can be generated from the running of this system in a country.

Microgrids are among the promising green transition technologies that will provide enormous benefits to the seaports to manage major concerns over energy crises, environmental challenges, and economic issues. However, creating a good design for the seaport microgrid is a challenging task, considering different objectives, constraints, and uncertainties involved. To ensure the optimal operation of the system, determining the right microgrid configuration and component size at minimum cost is a vital decision at the design stage. This paper aims to design a hybrid system for a seaport microgrid with optimally sized components. The selected case study is the Port of Aalborg, Denmark. The proposed grid-connected structure consists of renewable energy sources (photovoltaic system and wind turbines), an energy storage system, and cold ironing facilities. The seaport architecture is then optimized by utilizing HOMER to meet the maximum load demand by considering important parameters such as solar global horizontal irradiance, temperature, and wind resources. Finally, the best configuration is analyzed in terms of economic feasibility, energy reliability, and environmental impacts.

The Impact

Introduction. The topic of renewable energy today is one of the most relevant and requires consideration from the point of view of all components of this process, namely economic, financial, environmental, technological, and others. The transition to renewable energy is already irreversible today since natural resources are depleted, fuel prices are the subject to significant fluctuations, and the stable growth of the national economy is ensured by energy security. The purpose. The purpose of the article is to analyze the volume of global energy consumption, to analyze the impact of the introduction of renewable energy sources on the development of the national economy, to ensure energy security with the depletion of hydrocarbon resources and a slight diversification of their suppliers. Results. Today the Ukrainian economy is the most energy-intensive. Unstable energy prices are a threat both to the global economy and to each country separately. Therefore, in the event of a decrease in the supply of traditional energy resources, the importing countries experience the greatest difficulties. The existing tendency in Ukraine to increase the consumption of traditional energy sources, combined with the absence of a targeted policy aimed at reducing the volume of environmental pollution, will lead to an increase in negative economic consequences. The advantage of renewable energy sources is their equal distribution throughout the country (with the exception of water resources). This feature leads to the formation of one of the main characteristics of power systems based on renewable energy sources, namely, their decentralization. It should be borne in mind that the world energy market is made up of state and non-state participants. Non-state participants are showing an upward trend. However, the state should have the greatest influence on the national energy sector. Renewable energy is an area that, in the Ukrainian context, depends on state support, namely economic and administrative incentives. The dynamics of the development of renewable energy should be combined with the balanced development of the fuel and energy sector in Ukraine. Conclusions. The process of development and transition to renewable energy needs a systematic approach. Both qualitative and quantitative approaches are needed to assess the transition to renewable energy. An effective strategy for the transition to the introduction of renewable energy technologies should be justified by economic feasibility. The transition from traditional energy to renewable sources should lead to energy security, which contributes to stable economic growth, political independence, and improving the quality of the environmental component.

Abstract Industrial parks may be high pollutants of the local environment, but also engines of regional development, employment, and economic value added. To make them more sustainable, regional planning often purports to promote a transition to a greener approach, but in reality, many green measures oppose business logic and profitability, while those companies that do invest in sustainable solutions do so without having a clear strategy. This complicated setup is to be explored and modelled in this article which is focused on a remarkable area, the urban region of Székesfehérvár, an industrial city in Hungary having an impressive economic development and hosting significant domestic and international companies. The disharmony between greening policies, intentions and actions is observable in Székesfehérvár, despite the considerable local and regional potentials of renewable energy resources. Findings indicate that systemic thinking and future-oriented decision making will be necessary to achieve true sustainability, which also requires a mutually proactive attitude and the cooperation of different sectors. A legitimate strategy aiming at greening the local and regional economy (with renewable energy concerns), implemented by both public and business actors can be the key element of a successful transition. This strategy needs to be stimulated by local governance.
