The Energy Mix Concentration Index (EMCI): methodological considerations for implementation
(Elsevier B.V., 2019) Rubio Varas, María del Mar; Muñoz Delgado, Beatriz; Institute for Advanced Research in Business and Economics - INARBE
The Energy Mix Concentration Index (EMCI)is a quantitative indicator of concentration of the energy mix based upon the Herfindahl-Hirschman Index. We use the EMCI to compare the evolution of the diversification (versus concentration)of energy mixes in the long-term in order to reveal the transformations of the energy structures which determine energy transitions. In this methodological paper we make explicit how to aggregate the energy sources in order to calculate the EMCI, including questions of detail such us the level of aggregation and the transformation of primary electricity to add it up to total consumption. We present alternative figures that illustrate some additional aspects of the relation of the EMCI to total consumption, consumption per capita and energy annual growth. We also show the sensitivity of the indicator to alternative specifications (with and without pre-modern energy sources)and alternative data sets, proving its robustness. Indicate how to aggregate energy carriers in the calculation of a quantitative index of concentration of the energy mix. Compare alternative specifications (with or without pre-modern energy carriers). EMCI focus on the major energy sources in the energy systems.

España y Euratom
(Sociedad Nuclear Española (SNE), 2024) Rubio Varas, María del Mar; Torre Campo, Joseba de la; Economía; Ekonomia
Mientras que las Agencias nucleares de la ONU y la OECE/OCDE nacieron a posteriori de la organización matriz, la Comunidad Europea de la Energía Atómica (Euratom) nació ya como parte de los Tratados de Roma en 1957 que dieron luz a las Comunidades Europeas, y con sus mismos miembros originales (Bélgica, Francia, Alemania Occidental, Italia, Luxemburgo y los Países Bajos). A diferencia del Organismo Internacional de la Energía Atómica (OIEA) y de la Agencia Europea de la Energía Nuclear (AEN), en cuyas discusiones nucleares intervendría España como uno más antes de 1959, la participación formal en Euratom hubo de esperar hasta la integración en la Comunidad Económica Europea en 1986. Ello no quiere decir que no existieran otro tipo de vínculos y de acceso desde Madrid a lo que ocurría en Euratom antes de esa fecha. En su devenir histórico, Euratom se verá afectada por las crisis y ampliaciones de su organización matriz con mucha más virulencia que los otros organismos internacionales dedicados a la energía atómica. En este capítulo presentamos primero la constitución de Euratom y sus dificultades internas anteriores a la adhesión española, para después adentrarnos en las relaciones de Euratom con España.

Indicators and recommendations for assessing sustainable healthy diets
(MDPI, 2021) Martínez Aldaya, Maite; Ibáñez Moya, Francisco C.; Domínguez-Lacueva, Paula; Murillo Arbizu, María Teresa; Rubio Varas, María del Mar; Soret Lafraya, Beatriz; Beriain Apesteguía, María José; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD; Institute for Advanced Research in Business and Economics - INARBE
Research coupling human nutrition and sustainability concerns is a rapidly developing field, which is essential to guide governments' policies. This critical and comprehensive review analyzes indicators and approaches to 'sustainable healthy diets' published in the literature since this discipline's emergence a few years ago, identifying robust gauges and highlighting the flaws of the most commonly used models. The reviewed studies largely focus on one or two domains such as greenhouse gas emissions or water use, while overlooking potential impact shifts to other sectors or resources. The present study covers a comprehensive set of indicators from the health, environmental and socio-economic viewpoints. This assessment concludes that in order to identify the best food option in sustainability assessments and nutrition analysis of diets, some aspects such as the classification and disaggregation of food groups, the impacts of the rates of local food consumption and seasonality, preservation methods, agrobiodiversity and organic food and different production systems, together with consequences for low-income countries, require further analysis and consideration.

Water policy requires well established metrics for success. Precise metrics allow for quantifying progress and adjusting processes to produce the desired outcomes. We analyze the different schools of thought, nomenclatures and indicators developed for tracking water for human activities. After comparing a variety of terms related to water accounting used to serve the different purposes (environmental vs. ecological economics), we found that the different approaches to water tracking utilize identical terms to refer to distinctive concepts. The characterization of widely used terms such as 'water use' varies across different branches of literature. Different approaches to water measurement and its efficiency have an impact on water allocation. Our paper points out that the current definitions and methods for tracking water for human activities may offer contradictory advice over whether progress is being made towards desirable objectives, which may differ across stakeholders. This review aims at helping the transfer of academic results to empirical decision-making by discerning the differences among the variety of indicators available in the literature and their empirical implications. The ambiguity in the water terminology should be clarified before policy decisions can be useful in practice for guiding actions.

Agua dulce para refrigeración: una visión a largo plazo de la huella hídrica de las centrales nucleares en España
(2016) Sesma Martín, Diego; Rubio Varas, María del Mar; Ekonomia; Institute for Advanced Research in Business and Economics - INARBE; Economía
Objectives: our research pioneers a first approximation to the water footprint of the Spanish nuclear power plants operating with freshwater from 1969 to the present. Our aim is to calculate the consumptive use of water (i.e. the amount of water evaporated, transpired, or incorporated in energy production) for Spanish nuclear power plants, and the amounts of water withdrawals required for running nuclear power plants. To sum up, what is the water impact of our nuclear power plants? Will water limit our energy future? Should water be considered when planning the electricity mix in the future? These are some of the questions to solve.

Learning by doing: the first Spanish nuclear power plant
(Cambridge University Press, 2018) Torre Campo, Joseba de la; Rubio Varas, María del Mar; Economía; Ekonomia
In the nuclear sector, turnkey projects can be considered an investment in obtaining information through “learning by doing” to capture rents from the next generation of reactors. As the first U.S. turnkey export project, the first Spanish nuclear power plant served that purpose and paved the way to the subsequent growth of the nuclear sector, for both Spanish and U.S. firms. Making use of archival material, we analyse the networks created by the government, experts, and business leaders, which sought to obtain, accumulate, and learn from the scarce and conflicting information about atomic technology that was available at the time. We also discern how firms on both sides of the Atlantic acquired and perfected the specific capabilities required to build a commercial nuclear reactor.

The power of persuasion: exploring the relationship between advertising and nuclear energy in Spain
(Emerald, 2024-12-09) Aramendia Muneta, María Elena; Rubio Varas, María del Mar; Torre Campo, Joseba de la; Economía; Ekonomia; Gestión de Empresas; Enpresen Kudeaketa; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, PJUPNA2023–11931
Purpose: this study aims to examine how the nuclear energy issue was used for advertising purposes at the dawn of the atomic era in Spain. Design/methodology/approach: newspapers and magazines from the atomic era were reviewed to assess the impact of nuclear energy on advertising campaigns for all kinds of unrelated products. This study interprets the message and information contained in several marketing campaigns from the detonation of the first nuclear bomb in 1945 until the inauguration of the first nuclear facility in Spain in 1968. Findings: private companies leapt at the chance to use the new technology, with its promises of a brighter future, to promote their products, including watches, Venetian blinds, anisette, chocolates, pencils and fountain pens, spa resorts, books and encyclopaedias, laundry detergents, pressure cookers, concentrate feeds and hair restorers. This study makes a major contribution to the history of marketing literature, focusing on nuclear energy as an influential agent in industry, advertising agencies and popular culture. It shows how advertising campaigns used terms such as 'nuclear', 'atomic' and 'atomic bomb' and images of mushroom clouds or atom symbols to denote modernity and allure and explores how government policies - in this case, concerning nuclear energy - can influence marketers and advertisers. Originality/value: the paper's originality stems from its analysis of Spanish advertisements to explore marketing history through the terms and imagery associated with nuclear energy and its industry. It further contributes to the understanding of how nuclear energy is represented and conceptualised for various purposes in popular culture.

Nuclear engineering and technology transfer: the Spanish strategies to deal with US, French and German nuclear manufacturers, 1955–1985

We analysed the process of construction and connection to the electrical grid of four Spanish nuclear power plants with different financial and technological foreign partners: those of Zorita (PWR by Westinghouse), Garoña (BWR by General Electric) and Vandellós I (GCR by EDF) (belonging to the first generation of atomic plants and producing electricity from 1969–72) and that of Trillo I (PWR by KWU, connected in 1988). These four examples allow us to observe how the learning curve of nuclear engineering and the acquisition of skills by Spanish companies evolved. Progressively the domestic industry achieved higher levels of participation, fostered by the Ministry of Industry and Energy. When the atomic plants under construction were paralysed by the nuclear moratorium of 1984, and several other projects were abandoned by the utilities along the way, Spain had developed an industrial sector around the fabrication of service components and engineering for nuclear power plants to compete internationally.
