Discovered in Spain: Mysterious Vortexes of Energy Vanishing Away
Spain, a country renowned for its abundance of renewable energy resources, is grappling with an unexpected challenge. Due to a phenomenon known as 'curtailment' or renewable energy cutback, a significant amount of clean energy generated in the country is going to waste.
The issue arises from a geographical mismatch. Most of the renewable energy is produced in rural areas, where population density is low, while consumption is concentrated in large cities. This discrepancy has led Spain to resort to emergency measures, as some of the energy generated is lost before it can reach homes and businesses.
The electric car paradox in Spain, while surprising, is a smaller issue compared to the paradox of clean energies. A prime example is the solar power plant in Arenas de San Juan, which loses 30.4% of the energy it generates, equivalent to more than 25 GWh. Other plants like Carroyuelas and Aceca also experience similar losses, with 28.89% and 26% energy loss respectively.
The problem is further compounded by a mismatch between the times of highest renewable energy generation (April) and the times of highest electricity consumption (winter). This discrepancy creates 'invisible black holes' that absorb the renewable energy generated by solar and wind parks in Spain.
However, Spain is not backing down. The country, which attracts attention from all over the world for its energy models, is taking urgent measures to address the energy loss issue. The goal is to bet on smart grids in the medium term, aiming to reduce energy loss by up to 30% through large-scale storage, batteries, and smart grids equipped with sensors and artificial intelligence.
EU-funded research projects such as MOST at the Universitat Politècnica de Catalunya are working on innovative hybrid energy systems to reduce losses and improve efficiency. Additionally, companies like AIKO and its partners, who developed Spain's largest solar community project in Almonte, are supplying renewable energy directly with high-efficiency solar modules.
Local solar power communities, energy storage optimization, and advanced system controls to smooth power output and reduce inverter demands are already underway. The ultimate aim is to ensure that every watt of renewable energy generated in Spain reaches the homes and businesses it was intended for.
Countries, including Spain, have set the goal of transitioning to renewable energies due to the high cost and environmental impact of traditional energy sources. By addressing the energy loss issue, Spain is not only ensuring a cleaner future but also paving the way for other nations to follow suit.
