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.

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.

El Estado y el desarrollo de la energía nuclear en España, c. 1950-1985
(Asociación Española de Historia Económica (AEHE), 2014) Torre Campo, Joseba de la; Rubio Varas, María del Mar; Economía; Ekonomia
Tres décadas después de la decisión gubernamental de paralizar y replantear el programa atómico español que se había diseñado en los años del desarrollismo, la controversia permanece abierta. Pese a su relevancia, la historiografía económica de la energía nuclear está tan sólo en sus inicios. Este trabajo analiza el papel que el Estado jugó para conseguir que uno de los países más pobres de Europa occidental entrara en el exclusivo club de países productores de esa energía. Proponemos una nueva periodización del avance de la energía nuclear en España basada en la evolución político‐económica del sector que va más allá de los estadios tecnológicos que se describen en la literatura.

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.

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.

Las dimensiones sociales de la percepción de la energía nuclear. Un análisis del caso español (1960-2015)
(CSIC, 2017) Espluga Trenc, Josep; Medina, Beatriz; Presas, Albert; Rubio Varas, María del Mar; Torre Campo, Joseba de la; Economía; Ekonomia
La energía nuclear es una tecnología compleja, que requiere un uso muy intensivo de recursos y una toma de decisiones muy centralizada, cuya gobernanza supone un auténtico reto para las sociedades democráticas. En el presente artículo se exploran las percepciones sociales sobre la energía nuclear en España a partir de un análisis de encuestas de opinión y de los argumentos de actores de tres estudios de caso (Vandellós I, Valdecaballeros y ATC). Los resultados muestran cómo las argumentaciones de unos y otros actores se basan en diferentes dimensiones del riesgo, a menudo ignoradas en las encuestas y por varios de los actores, lo cual supone una seria dificultad para superar las controversias suscitadas por este tipo de energía.

200 years diversifying the energy mix? Diversification paths of the energy baskets of European early comers vs. latecomers
(Universidad Autónoma de Madrid, 2017) Rubio Varas, María del Mar; Muñoz Delgado, Beatriz; Economía; Ekonomia
The changes in the composition of the energy basket in the long run lead to energy transitions. Primary energy substitution models allow addressing these phenomena. However, the diversification paths of the energy mix of different countries in a long term compared perspective have not been studied yet. This paper proposes an indicator, based on the Herfindahl‐Hirschman Index, the Energy Mix Concentration Index (EMCI), to quantify the degree of diversification of the primary energy basket of eight European countries over the last two centuries. The results reveal that early comers, which are large energy consumers, required a huge concentration of their energy basket in the 19th century; however, the observed countries had converged to similar levels of diversification of their energy mixes from the second half of the 20th century, and more crucially after the oil crises. For some countries, today’s degree of diversification is the largest in their energy histories, but it is not the case for all of them. Our results suggest that small energy consuming countries would be able to achieve higher diversification, and therefore to do a faster transition to a low carbón economy, than large energy consumers.

"Spain-Eximbank's billion dollar client": the role of the us financing the Spanish nuclear program
(Asociación Española de Historia Económica (AEHE), 2016) Rubio Varas, María del Mar; Torre Campo, Joseba de la; Economía; Ekonomia
En 1972, Henry Kearns, presidente y director del Export-Import Bank de los Estados Unidos (Eximbank), visitó la Cámara Oficial de Comercio e Industria de Madrid. El título de su discurso'España – el cliente del billón de dólares del Eximbank' daba cuenta del importante papel que el banco público estadounidense jugaba en la financiación de las compras españolas de bienes de equipo, como aviones, fábricas de acero, estaciones satelitales y plantas eléctricas, entre otros. La concentración en nuevas instalaciones de generación eléctrica convertía a España en aquel momento en el país con el más rápido desarrollo de energía nuclear de Europa, y el mayor comprador de tecnología nuclear de los EE.UU. mano a mano con Japón. Ninguna otra nación se acercó a estos dos en ese sentido. Utilizando materiales de archivo del Eximbank y la Administración Nacional de Archivos y Registro de los Estados Unidos (NARA), exploramos las facilidades financieras que los EE.UU. proporcionaron al programa nuclear español, el tamaño de los créditos autorizados y su evolución en el tiempo. Se hace evidente que el bombeo de dinero público norteamericano para la exportación de las instalaciones nucleares en el mundo explica en gran medida el cuasimonopolio del mercado nuclear mundial que los EE.UU. tuvieron antes de la década de 1980, y en particular su importancia para convertir a España en uno de los pioneros y líder en la adopción de la tecnología nuclear.

Machines and energy. Energy capital ratios in Europe and Latin America 1875 - 1970'
(Taylor & Francis, 2018) Ducoing Ruiz, Cristián; Gales, Ben; Hölsgens, Rick; Rubio Varas, María del Mar; Ekonomia; Institute for Advanced Research in Business and Economics - INARBE; Economía
The relationship between energy and capital is one of the most important aspects of modern economic growth. Machines need energy to produce all the goods we enjoy; energy would be far less useful for humankind in absence of machines. However, the great majority of the economic models do not take into account the elasticities of substitution (or complementaries) between these two main variables. Actually, energy is absent in many growth models and discussions on diverging economic development paths. We approach this relevant issue from a new perspective: energy and capital relations during 100 years. We use the latest estimations of capital stock (machinery and equipment) and energy consumption for Latin America and compare them with those of Western Europe. The energy–capital ratio (how much energy is used per unit of capital) could be a predictor of economic growth, thus providing stylised facts about the timing and causes of the different modernisation patterns of these regions and showing us some answers on the long-run relationship between energy consumption and capital accumulation.
