An environmental dispatch examines sustainable energy transitions in the Canary Islands:
On the remote volcanic island of El Hierro in Spain's Canary archipelago, municipal engineers have addressed the structural vulnerabilities of isolated island grids through an innovative hybrid infrastructure known as Gorona del Viento. By pairing a five-turbine wind farm directly with a pumped-storage hydroelectric facility installed inside a natural volcanic crater, the project resolves the core challenge of renewable intermittency. During periods of surplus wind generation, excess electrical power pumps desalinated water up to the elevated volcanic reservoir. When wind speeds subside, water descends through hydraulic turbines to generate electricity instantaneously, stabilizing the municipal grid without burning imported diesel. Although ongoing maintenance of the upper reservoir and ecological monitoring demand specialized technical oversight, the system has successfully supplied up to eighty percent of the island's annual electricity demand. Rather than treating clean generation as isolated technologies, the island's model demonstrates that pairing complementary production and storage systems is essential to securing reliable energy self-sufficiency in remote regions.
Which of the following best expresses the primary main idea of the passage?
- APumped-storage hydroelectric reservoirs built in volcanic craters require costly technical maintenance and environmental oversight to remain functional.
- Integrating complementary renewable generation with dynamic storage mechanisms enables remote regions to achieve dependable energy autonomy.Cevap
- CThe Gorona del Viento installation has completely eliminated all fossil fuel consumption across the entire Canary archipelago.
- DStandalone wind turbine farms are fundamentally incapable of providing clean electricity to municipal power networks.
