At the crossroad between green and thirsty: carbon emissions and water consumption of Spanish thermoelectricity generation, 1969–2019
(Elsevier, 2022) Cano-Rodríguez, Sara; Rubio Varas, María del Mar; Sesma Martín, Diego; Institute for Advanced Research in Business and Economics - INARBE
The energy sector is the main contributor to greenhouse gas emissions and one of the thirstiest sectors worldwide. Within the energy sector, thermoelectricity directly impacts on both emissions and water. This study assesses the evolution of the direct CO2 emissions and operational water consumption of the Spanish thermoelectricity generation from 1969 to 2019. Both carbon emissions and water consumption correlate over time, led by the trends in total thermal generation, although over the past half century, water requirements swelled far more than carbon emissions. This results in a long-term trade-off between carbon emissions and consumptive water use in relative terms: while the CO2 per thermal MWh generated halved since 1969 in Spain, the operational water consumption per MWh of thermoelectricity generated more than doubled due to switching from coal burning to nuclear and combined cycle technologies. We find no real trade-off in absolute levels. Although moving towards smaller environmental impacts since the mid-2000s, thermoelectricity remains one of the largest carbon emitters while becoming one of thirstiest energy technologies in Spain.

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.

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.

Nuclear engineering and technology transfer: the Spanish strategies to deal with US, French and German nuclear manufacturers, 1955–1985
(Routledge, 2020) Torre Campo, Joseba de la; Rubio Varas, María del Mar; Sánchez Sánchez, Esther M.; Sanz Lafuente, María Gloria; Ekonomia; Institute for Advanced Research in Business and Economics - INARBE; Economía
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.

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.

Energy as an indicator of modernization in Latin America, 1890-1925
(Wiley, 2010) Rubio Varas, María del Mar; Yáñez, César; Folchi, Mauricio; Carreras, Albert; Economía; Ekonomia
In the absence of comparable macroeconomic indicators for most of the Latin American economies before the 1930s, the apparent consumption of energy is used in this paper as a proxy of the degree of modernization of Latin America and the Caribbean. This paper presents an estimate of the apparent consumption per head of modern energies (coal, petroleum, and hydroelectricity) for 30 countries of the region, 1890 to 1925. As a result, it provides the basis for a quantitative comparative analysis of modernization performance beyond the few countries for which historical national accounts are available in Latin America.

The weak data on the water–energy nexus in Spain
(IWA Publishing, 2019) Sesma Martín, Diego; Rubio Varas, María del Mar; Ekonomia; Institute for Advanced Research in Business and Economics - INARBE; Economía
This paper focuses on the fact that the water–energy nexus remains an irrelevant issue on the energy policy agenda and on the priorities of the energy leaders in Spain. This is a striking fact given that this takes place in the most arid country in Europe, where almost two-thirds of electricity generation would have to be halted in the absence of an adequate water supply. We contend that part of the explanation may lie in the lack of official statistics and inconsistent sources of information on the water–energy nexus in Spain. To illustrate this point, we provide examples of the uneven data available for one of the most intensive freshwater users in the thermoelectric sector in Spain: nuclear power plants. Our research demonstrates the need for improved indicators as policy instruments in the water–energy nexus in Spain since it is impossible to improve what cannot be measured.

Freshwater for cooling needs: a long-run approach to the nuclear water footprint in Spain
(Elsevier, 2017) Sesma Martín, Diego; Rubio Varas, María del Mar; Ekonomia; Institute for Advanced Research in Business and Economics - INARBE; Economía
From the invention of the steam engine to the present, water has represented a significant input to the energy system, although this has been mostly ignored in the literature. In Spain, the most arid country in Europe, studies about water footprint typically just consider domestic, agricultural and industrial water uses, but water requirements for the electricity sector are omitted despite our dependence on thermal power. It has been demonstrated that for each available cooling technology, nuclear needs and consumption of water tend to be larger per MWh generated. We calculate a first approximation to the Spanish nuclear water footprint from 1969 to 2015. Our results show that while water consumed by Spanish nuclear power plants are around 3 m3 per capita/year, water withdrawals per capita/year are around 70 m3. Moreover, our analysis allows extracting conclusions focusing on a River Basins approach. What is the water impact of our nuclear power plants? Will water limit our energy future? These are some of the issues at stake.
