https://science.feedback.org/what-caused-iberias-blackout/ After Spain and Portugal lost electricity on 28 April 2025, renewable energy opponents were quick to blame solar and wind for destabilizing the peninsula’s electric grid. But it’s too early to blame anything for the blackout. As of this writing, authorities are still investigating the blackout's cause. Electric grids are tremendously complex, and blackouts like this usually happen only when multiple things go wrong at once. Even experts may need a month or more to sort out what happened. What we do have is a preliminary sequence of events. There’s been a lot of speculation based on these events, and it may be the case that renewables have some relation to the blackout’s cause – but, as experts told Science Feedback, we can’t know for sure. We can say, however, 𝘁𝗵𝗮𝘁 𝗮𝗱𝗱𝗶𝗻𝗴 𝗿𝗲𝗻𝗲𝘄𝗮𝗯𝗹𝗲𝘀 𝘁𝗼 𝘁𝗵𝗲 𝗴𝗿𝗶𝗱 𝗱𝗼𝗲𝘀 𝗻𝗼𝘁 𝗮𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗰𝗮𝗹𝗹𝘆 𝗺𝗮𝗸𝗲 𝗶𝘁 𝗺𝗼𝗿𝗲 𝘃𝘂𝗹𝗻𝗲𝗿𝗮𝗯𝗹𝗲 𝘁𝗼 𝗯𝗹𝗮𝗰𝗸𝗼𝘂𝘁𝘀. Electric grid operators are well aware how to adapt grids for solar and wind. Fossil fuel defenders and other renewable energy opponents like to blame wind and solar for all sorts of problems – but, as in this case, their claims often mislead.
