MADRID — FOR FRIDAY 0500GMT
The massive power outage that hit the Iberian peninsula on April 28 has reignited a debate in Spain over the country’s plan to phase out its nuclear reactors as it generates more power with renewable energy.
As people wait for answers about what caused the historic power cut, which abruptly disrupted tens of millions of lives, some are questioning the wisdom of decommissioning nuclear reactors that provide a stable, if controversial, form of energy compared to renewables, whose output can be intermittent.
Spanish Prime Minister Pedro Sánchez has rejected such criticism, asking for patience while the government investigates what caused the grid’s disconnection. He said that his government would not ”deviate a single millimeter” from its energy transition plans.
Here’s what to know about the energy debate:
What is nuclear power and why is it controversial?
Nuclear power is a zero-carbon energy source formed from nuclear fission, when the nuclei of atoms are split into two or several parts, releasing energy.
It accounts for about 10% of electricity generation worldwide, according to the International Energy Association.
