The legacy of hydraulic engineering: hidden treasures of Asturias

Hydroelectric energy will play a transcendental role in the ecological transition to green energy. Although the power of water has been harnessed by human beings since time immemorial, it was not until the Industrial Revolution that the first hydroelectric power plant was built. Electrical infrastructures of this kind were also built in Spain and Asturias during the 20th century, successfully contributing to the development of the region. This article takes a journey through the most unique hydroelectric infrastructures in the Asturian hinterland, describing their technical characteristics and historical context. It concludes with an analysis of the impact caused on society, the economy and environment of the region.
