Spain's strong commitment to renewable energy is facing scrutiny after a widespread blackout and growing calls for a more diversified energy mix. While a massive new electric vehicle battery factory near Figueruelas symbolizes the country's green transition, recent events have sparked debate about the reliability of an overwhelmingly renewable grid.

• Renewables accounted for 57% of Spain’s electricity production last year, up from one-third in 2017.
• A €4bn ($4.7bn; £3.5bn) investment by CATL (Chinese firm) and Stellantis (Netherlands-based) for a new battery factory in Figueruelas, Aragón, is one of the largest Chinese investments in Europe.
• The April 28 blackout, which affected Spain and Portugal, has led to conservative opposition leaders, like Alberto Núñez Feijóo, questioning the government's "fanaticism" in pursuing its green agenda.
• The government plans to close Spain's five nuclear plants between 2027 and 2035, despite calls from the nuclear industry and political opposition for their continued operation to ensure grid stability.
• Spain's head of operations for Red Eléctrica, Concha Sánchez, denies the blackout was due to renewables, citing "an unknown event" and anomalous voltage oscillations.
