Enel X is leading the transition toward a sustainable business model, with the circular economy as an important pillar. Using renewable energy sources and materials, extending product life cycles, creating sharing platforms, reuse and regeneration, rethinking products as services. The principles of the circular economy have become essential, considering the paradigm shift overturning the traditional linear economic model. Enel X was one of the first businesses to offer products on the market that concretely apply the five business models of the circular economy and reconsider the entire value chain from a sustainability perspective. This approach is characterized by two core principles: 1.  the first, addressed internally, focuses on the business’s product portfolio, which ranges from “measuring” circularity to identifying solutions for improvement; 2.  the second is directed toward the outside, and especially toward industrial customers and public administrations or end customers, with the goal of evaluating their level of “circularity” and helping them outline a roadmap to circularity.

Support Functions

The gradual displacement of synchronous generators driven by conventional power plants, due to the increasing penetration of distributed renewable energy sources (DRES) in distribution grids, is creating a shortage of crucial ancillary services (AS) which are vital for the frequency and voltage stability of the grid. These AS, and some new ones, could now be offered by the DRES, particularly those that are converter interfaced, in a coordinated way in order to preserve the grid stability and resilience. Although recent standards and grid codes specify that the DRES exhibit some system support functions, there are no specifications on how to measure and quantify (M & Q) them both at DRES level and in aggregated form. The M & Q of AS is crucial, since it would allow the AS to be treated as tradable AS in the current and future AS markets. This paper attempts to define a number of AS that can be offered by converter-interfaced DRES and suggests methods for their M & Q. The new AS addressed are: (1) inertial response; (2) primary frequency response; (3) active power smoothing (ramp-rate limitation); (4) exchange of reactive power for voltage regulation; (5) fault-ride-through (FRT) and contribution to fault clearing; (6) voltage harmonic mitigation. Additionally, a rough estimation of the additional investment and operational cost, as well as the financial benefits associated with each AS is provided in order to form the basis for the development of business models around each AS in the near future.

The Subject

The subject matter addressed in the paper concerns digital technology platforms in the context of renewable energy sources. The main goal is to check whether digital technology platforms can be effective factors in implementing innovative business models in the RES sector. The study was based on empirical research using Computer-Assisted Telephone Interview (CATI) and Computer-Assisted Web Interview (CAWI) methods, as well as on a model of attitudes towards digital technology platforms (DTPs) built using CATREG (categorical regression) analysis. As a result of the research, it was found that digital technology platforms contribute to building innovative business models. The decisive influence on this is a number of benefits for enterprises and consumers (and the related factor is the most important when it comes to attitudes towards DTP), as well as the high interest in digital RES platforms.

The Impact

The life cycle of renewable energy sources has been analyzed in the research paper. The differences and specific features of life cycles of traditional and renewable energy sources have been identified. A proprietary scheme of the life cycle of renewable energy sources has been proposed, which takes into account the identified features compare to traditional energy sources. The renewable energy life cycle consists of three stages and ten phases. The eco-destructive impact of renewable energy sources at each stage of the life cycle has been investigated and presented, which makes it possible to assess objectively and take into account the complex eco-destructive impact of the use of a specific object that uses renewable energy sources. The studies of Al-Mulali, Apergis, and Payne, Dogan and Turkekul, Menegaki, confirming the relationship between growth indicators (Gross Domestic Product) and the growth of energy produced by renewable energy sources were examined. The total electricity consumption in the world for the period 1973–2016 was considered. Comparisons of traditional and renewable energy sources by service life and life cycle are given, and the main stages and phases of the life cycle of renewable energy sources are examined in detail. The stages of development and creation of renewable energy technology, namely the stages of development and creation of renewable energy technology, the operation of renewable energy facilities and the utilization and recycling of renewable energy components were considered. The impact of renewable energy on the environment from reservoirs and the specific effects of the use of renewable energy facilities has been studied. To identify adverse factors of influence, from eco-destructive impact, the stages of the structural composition of the renewable energy life cycle were examined to find possible ways to eliminate them at each stage. Key words: renewable energy sources, life cycle, energy, energy production, management of natural resources.

The Impact

This article aims to examine the impact of corporate social responsibility, trust, and sustainable business strategies on the diffusion of innovative solutions in renewable energy sources. In this context, the material from the edition of the reports of the Polish Agency for Enterprise Development on innovation in the renewable energy industry was analyzed. A survey was also conducted among enterprises from the SME sector on the creation of a business model taking into account the diffusion of innovation in the field of renewable energy sources. The SME sector consists of entities that usually do not have an extensive organizational structure or research and development teams. Nevertheless, in the current economic situation, it is required that they are highly competitive, including through implemented innovations. Conscious participation of SME entities in the process of diffusion of innovation may be a solution that brings innovative solutions closer. The author stated that social responsibility had a moderate impact on the diffusion of innovation in the field of renewable energy in the SME sector, as it contributed the most to building trust in uncertain energy sources. On the other hand, the study conducted by the author showed that greater experience in the field of social responsibility (the company has a CSR department, there is a person responsible for CSR in the company, the company has a CSR policy, the company has a Code of Ethics, social reports are prepared in the company) had a positive relationship with building trust and commitment to innovative activities related to renewable energy sources. Conscious participation of SME entities in the process of diffusion of innovation may be a solution that approximates innovative solutions.

Bayesian Network Classifier

Willingness to invest in renewable energy sources (RES) is predictable under data mining classification methods. Data was collected from the area of Evia in Greece via a questionnaire survey by using a sample of 360 respondents. The questions focused on the respondents’ perceptions and offered benefits for wind energy, solar photovoltaics (PVs), small hydro parks and biomass investments. The classification algorithms of Bayesian Network classifier, Logistic Regression, Support Vector Machine (SVM), C4.5, k-Nearest Neighbors (k-NN) and Long Short Term Memory (LSTM) were used. The Bayesian Network classifier was the best method, with a prediction accuracy of 0.7942. The most important variables for the prediction of willingness to invest were the level of information, the level of acceptance and the contribution to sustainable development. Future studies should include data on state incentives and their impact on willingness to invest.

India’s energy needs are in demand with the increase in energy and other electric uses which is highest among the world. There are sectors which heavily rely on energy generated by fossil fuels but there is also seen a paradigm shift towards renewable energy sources. If India continues to rely on the former then they end up blocking development in energy system meeting uncertainties and face difficulties in supply of fossil fuels. To meet the fast-growing economy, India needs to supply the energy 3-4 times more of what they are supplying now. Government of India has become aware of the situation and has started facilitating polices in action towards a sustainable energy. As of 2019, India’s on grid renewable energy capacity is 85.9 GW. Government is working to establish 500 GW of renewable energy source by 2030.

Structured Questionnaire

The limits of the present take-make-waste business model are extremely visible when examining the textile and clothing industry. The concept of circular economy gained traction, which has led to the creation of policy actions throughout the life cycle of a product and at disposal. Transitioning from linear to circular economy business models requires significant value-chain changes in both production and consumption patterns. Existing circular business models are paving the way towards a paradigm shift. However, the literature has not retained much empirical evidence about these sustainabilityoriented innovators which are invisible and work in anonymity. This study provides a simple, yet rich and unique overview of the characteristics of circular economy business models in the textile and clothing sector in Romania, identified through qualitative analysis performed on the entire population of sustainability-oriented innovators identified in Romania in the textile and clothing sector in a previous study done by the same author. The data was collected using a structured questionnaire with 37 questions connected to four areas: human resources, legal and fiscal framework, customers and communication, and materials, tools or technology employed. With a 100% response rate, the real significance of this paper is that it may have discovered the real contribution of these agents of change in the circular economy, functional circular business models which have never been studied before as a population.

In The Beginning

Energy transition from a carbon energy driven world to a decarbonized world (H2) is essential for the living for our next generations. Our existing energy source with contents in the beginning (1850) nearly only the element C are used with all their consequences for the burning process and environmental impact. Nowadays the C element in our present energy sources are getting less and less. The environmental impact using fossil energy is huge and with the climate change more and more deadly for the inhabitants on the earth. Producing H2 as a sustainable and renewable energy is only possible using renewable energy sources like PV, Wind, Hydro, Biomass. With today's technology and the constant falling energy prices since the last 20 years H2 is now an alternative secondary energy source for a substitute for fossil sources. Using H2 will give new and unique business advantages. With these business advantages, new and innovative business models can be designed and developed. These novel approaches can be very sensitive to external influences. This destructives situations are making these BM very fragile. Finding ways to stabilize these on a long term without aid from the outside the key for success are new innovative technologies and new innovative BM.

Comprehensive environmental impact assessments of buildings and construction as a whole consider the preparation of construction and finishing materials, their transportation, the process of erecting buildings, long-term operations—including the consumption of electricity, water, and fuels—and the management of the waste generated during the demolition of facilities. In terms of the above-mentioned elements, the most negative environmental impact on a building’s life cycle is in its exploitation stage. In order to reduce this impact, modern sustainable construction uses renewable energy sources. In the area of the Polish building market, analyses of CO2 emissions, the application of LCAs for building materials, and assessments of the social impacts of modern buildings are still very limited. The aim of this study is to evaluate the environmental life cycles and social costs of the CO2 emissions of single-family residential buildings, in which four different systems providing energy (heat and electricity) from renewable and nonrenewable sources are used. In this research, it was found that the annual CO2 emissions per square meter of building surface area in the analyzed objects were in the range of 30 to 176 kg CO2. The greatest contributor to the environmental effects was energy consumption (58% to 90%). The CO2 analysis conducted showed that facilities that use a heat pump are characterized by an environmental effect that is six times lower than that of facilities that are powered by coal combustion and electricity from the network. Similarly, the social costs associated with CO2 emissions were significantly lower in the case of the use of renewable energy sources.
