    Residuos de las aspas de los aerogeneradores ¿un problema futuro?
    (Gerencia Ambiental, 2023-06) Di Nanno, María Pía; Barisone, Manuela Alejandra; Menéndez, Gustavo
    Ya sea porque se produce la necesidad de reemplazar algún componente durante la construcción, operación y mantenimiento o en la etapa de desmantelamiento del parque, eventualmente surgirá la necesidad de evaluar cómo y dónde disponer los residuos generados por las aspas de los aerogeneradores. Cuál es la estimación de la generación prevista para la Argentina.

    Initial estimate of kinetic energy of tidal currents in the province of Chubut, Argentina
    (European Wave and Tidal Energy Conference, 2022-04-30) Lifschitz, Ana Julia; Coiro, Domenico P.; Troise, Giancarlo; Giaquinta, Horacio; Lazcano, Fabio Miguel; De Cristófaro, Norma
    This work is a preliminary study to find some sites for the potential use of tidal stream energy and their associated currents in the Chubut coast. In addition, an evaluation of the energy resource of the Chubut Gulfs is made. Among other possible technical solutions, in this work the exploitation of tidal energy is based on the use of hydrokinetic turbines, which transform the stream translational kinetic energy into rotational kinetic energy available to feed an electrical generator. The energy can be extracted analogously to that of wind energy; therefore, it is not necessary to build a dam, avoiding the environmental and economic disadvantages it represents. The total annual theoretically exploitable kinetic energy of the whole cross section at San José Gulf was estimated as 1,006 GWh/year, but assuming a device conversion efficiency of about 45%, this lowered to 453 GWh/year. Considering also some practical limitations due to the installation of multiple devices in a hypothetical farm layout, the annual available energy production for three turbines rows in the inlet of San José Gulf was 61 GWh/year. Such results were based on a preliminary analysis using a relatively small amount of data, which can give an initial estimate of the expected available resource in the area of interest. Future experimental investigations may improve the accuracy of the resource evaluation. Lower tidal kinetic energy was found in the Nuevo Gulf and at the Chubut River mouth, thus, a system to increase the flow should be considered.

    Which cooking and heating fuels are more likely to be used in energy-poor households? Exploring energy and fuel poverty in Argentina
    (Elsevier, 2021-12-29) Burguillo Cuesta, María Mercedes; Barisone, Manuela Alejandra; Juez-Martel, Pedro
    Energy poverty in emerging countries has mainly been analysed in the literature as a problem of energy supply accessibility. However, this analysis is too simple, as in many of these countries there can be a problem of energy accessibility that is not necessarily linked to an insufficiency of energy supply but is related to the use of certain types of fuels or facilities to meet the energy needs of the household. Moreover, what can explain the choice of these fuels can also be an affordability energy problem, and this has been scarcely treated on energy poverty papers focused on developing countries. This work aims to shed light on this literature, analysing both the affordability and the accessibility energy problem of Argentine households. To do so, we use micro-data from an expenditure-survey. First, we measure the energy affordability problem by calculating the Boardman indicator. Second, we estimate two logit models to show how likely it is that the affordability energy problem explains the choice of facilities for cooking and heating that can indicate an energy accessibility problem. Third, to refine the results of our estimations, we calculate the ROC curves to measure the levels in which energy-poor and non-energy-poor household are better identified than with the standard identification of logit models. The results show that it is more probable that households characterized by monetary energy poverty use facilities that indicate an energy accessibility problem than households that are not energy poor.
