Analysis of labour market needs for engineers with enhanced knowledge in renewable energy in some European and Latin-American Countries

One of the main challenges related to the renewable energy labour market is that of human capital and as a consequence the educational profile of future employees is of paramount importance. Unfortunately, the skill level gained at University does not always fit with the practical needs of industry thus reducing the benefit-cost ratio of new employees and slowing down the transition to a green economy. Within this context, ‘The Crux’ project co-funded by EU under the framework of the Erasmus + programme aims at improving the renewable energy engineering curriculum at different university levels in several Universities of Latin America and Europe. In order to better appreciate the potential impact of the project, a survey on the labour market need for specialists with enhanced knowledge and skills in renewable and sustainable energy technologies has been conducted in the related EU and Latin America countries. More precisely, 60 organizations have been interviewed and almost 70% of them are interested in employing engineers with enhanced knowledge on renewable energy in the next three years. The analysis has shown significant discrepancies between EU and Latin American organizations. In fact, while future employees in EU countries will be mainly related to solar energy and management, the former together with wind and biomass will represent the main renewable energy working sector in Latin American countries. Moreover, MSc level will be the most demanded in EU while bachelor education seems to satisfy the future industry requirements in Latin America. Despite each country having its own needs, the research carried out under this EU project confirms the potential of renewable energy education on the global labour market in the near future

Análisis sistémico de la selección de instalaciones de energías renovables en territorios aislados

The work presents research results obtained by the authors in the solution of optimal selection of renewable energy equipment task to meet the needs of a territory and each one of its parts from the offers available in the market and of the availability of energy resources in the territory. It is carried out a study of the existent research works, linked to the selection of energy installations, starting from those the antecedents settle down. A systemic analysis of the task is made, the conceptual mathematical model for the task, it complexity and the decomposition outline were determined for conditions close to the those that are present in the municipality of Ganda, Benguela province, Angola, taken as Study CaseEn el trabajo se presentan resultados investigativos obtenidos por los autores en la solución de la tarea de selección óptima del equipamiento en medios de energía renovable para satisfacer las necesidades de un territorio y de cada una de sus partes a partir de las ofertas disponibles en el mercado y de las disponibilidades de recursos energéticos en el territorio. Se realiza un estudio de los trabajos de investigación existentes, vinculados a la selección de instalaciones energéticas, a partir de los que se establecen los antecedentes, se hace un análisis sistémico de la tarea de selección de instalaciones energéticas, se determina el modelo matemático conceptual para la tarea, su complejidad y el esquema de su descomposición para las condiciones próximas a las del territorio del municipio Ganda, Benguela, Angola, tomado como caso de estudio del presente trabaj

Bioavailability and dosing strategies of mineral in anaerobic mono‐digestion of maize straw

The influence of the bonding form distribution of Fe, Ni, Co and Mn and their potential bioavailability during the anaerobic degradation of maize straw was investigated. Two reactors were operated over 117 days at 37°C and different dosage strategies of mineral were studied in reactor (R2). Control reactor (R1) was metal‐limited over time. mineral supplementation (1 g L−1) once a week reported the highest methane yield (257 mL g−1 VS) with 30% of increment. Ni and Co predominated in their oxidizable bonding forms and Fe mainly existed as residual and oxidizable fractions. The potential bioavailability (Mn ˃˃ Co ≈ Ni ˃ Fe) of R2 was higher comparing to R1. Metal deprivation in R1 led to depletion of both sequential extraction fractions and total metal concentrations until the end of the process. This study confirmed that the dosage strategy of mineral has a stimulatory effect on methane production from crop maize waste.18856256
