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.

Capacity Structure

The purpose of the paper is to develop a methodology for multi-criteria selection of the capacity of a group of power plants included in the local power system which use local energy resources and renewable energy sources. To form alternative options for the structure of generating capacities, an approach is proposed. It suggests setting of a number of power levels of the base-load generating plant and power plants using renewable energy sources with subsequent determination of the capacity of the flexing generating plant to cover the remaining part of the load schedule. For multi - criteria comparison of the alternative options of the generating capacity structure, the TOPSIS method is used, which is modified to take into account the uncertainty of the decision-maker's preferences (the modification of the method consists in using fuzzy value functions at the stage of normalizing estimates by criteria). The application of this method is considered on the example of the Okhotsk district of the Khabarovsk territory. The estimated capacity of prospective consumers is 69 MW. Alternative options of the power generation structures include four types of power plants: local coal -fired thermal, solar, wind, and diesel. The multi-criteria comparison of generating capacity structure options is performed using the following criteria: normalized cost of electrical energy, estimation of environmental efficiency, and assessment of public opinion on the consequences of power plant construction. Some of the most promising options for the structure of generating capacities are presented, depending on the values of the weight coefficients of the criteria. If the criterion has the large weight reflecting economic efficiency, the structure with the predominance of thermal power plant energy generation is the best. If the criteria of environmental efficiency and public opinion feature large weight, the best structure is the one with significant generation from a renewable energy source (solar power plant). The coefficients of using the installed capacity of different types of power stations with different structures of generating capacities are determined. It is shown that the proposed methodology provides the obtaining of the options of the generating capacity structure that correspond to expressed preferences, taking into account the uncertainty of the initial information and development scenarios. Promising options for the structure of generating capacities are selected for more detailed further research.

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 Social

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.

Over 90% of Uganda's power is generated from renewable sources. Standardised Implementation Agreements and Power Purchase Agreements create a long-term relationship between Generating Companies and the state-owned off-taker guaranteed by Government. The COVID-19 pandemic and measures to curb the spread of the virus have triggered the scrutiny and application of force majeure (FM) clauses in these agreements. This article reviews the FM clauses and considers their relevance. The authors submit that FM clauses are a useful commercial tool for achieving energy justice by ensuring the continuity of the project, despite the dire effects of the pandemic. Proposals are made for practical considerations for a post-COVID-19 future which provides the continued pursuit of policy goals of promoting renewable energy sources and increasing access to clean energy, thus accelerating just energy transitions.
