Energy Lab: "Energiaren Memoria” is a pioneering initiative designed to transform the historic industrial landscape of Gallarta into a benchmark for the energy transition in the Basque Country. Located at the Ekoetxea Meatzaldea, the project repurposes the post-industrial site of the Concha II Mine—once a symbol of environmental extraction—into a living laboratory for renewable energy and social awareness. The project integrates and monitors a hybrid system of four clean energy sources: geothermal and aerothermal systems already installed at the center, vertical axis wind energy (VAWT) via the Darwin rotor, and solar photovoltaics. By deploying an advanced IoT network using Hall effect sensors, shunts, and industrial PLCs, the laboratory captures high-fidelity data on energy flows. This infrastructure correlates generation with local meteorological variables, such as atmospheric pressure and humidity, to optimize performance and feed predictive models. 

The project expects to achieve significant results in energy sovereignty by demonstrating to Basque citizens that local resources can effectively replace fossil fuels. Scientifically, it will provide a detailed climatological study of the mine’s unique "inverse orography," where turbulent winds favor vertical turbines over conventional ones. Pedagogically, through interactive Grafana dashboards and dedicated educational units, the Ekoetxea will offer real-time visualization of energy generation and savings for schools and families. Ultimately, validated by the UPV/EHU, "Energiaren Memoria" aims to trigger a systemic change across Euskadi, positioning the region as a leader in decentralized, resilient energy production in harmony with its unique geology.
The concept for "Energiaren Memoria" was born from a personal and academic intersection during my fourth year of a Double Degree in Physics and Electronic Engineering at the University of the Basque Country (UPV/EHU). While exploring the historic Concha II mine in Gallarta, I realized the profound contrast between its extractivist past and the urgent need for a sustainable future. This reflection coincided with a call for projects on energy transition and social impact; although I did not submit to that specific call, it ignited a drive to develop a tangible solution that honors our industrial heritage while leading Euskadi toward energy sovereignty. 

The development of the concept is structured through a dual-scientific approach, integrating my two Final Degree Projects (TFG). From a Physics perspective, the project focuses on a climatological study of the mine’s unique "inverse orography," analyzing how its microclimate and turbulent winds interact with renewable technology. Simultaneously, the Electronic Engineering component involves designing and deploying a high-fidelity IoT architecture. This includes implementing a network of Hall effect sensors and split-core current transformers to monitor energy flows from a hybrid system of four sources: solar, vertical wind (Darwin rotor), geothermal, and aerothermal energy. 
The implementation strategy relies on transforming the Ekoetxea Meatzaldea into an active energy laboratory. Data collected by industrial PLCs is stored in a time-series database and translated into interactive Grafana dashboards for public visualization. This process ensures that complex technical data becomes a pedagogical tool for the community. By collaborating with academic advisors and the Ekoetxea network, the project moves from a solitary idea to a systemic change for the entire Basque Country.
