You’ve heard of water droughts. Could ’energy’ droughts be next ?

Titre : You’ve heard of water droughts. Could ’energy’ droughts be next ?

Renewable energy prices have fallen by more than 70 percent in the last decade, driving more Americans to abandon fossil fuels for greener, less-polluting energy sources. But as wind and solar power continue to make inroads, grid operators may have to plan for large swings in availability.

Résumé
Drawing on 70 years of historic wind and solar-power data, researchers built an AI model to predict the probability of a network-scale ’drought,’ when daily production of renewables fell below a target threshold. Under a threshold set at the 30th percentile, when roughly a third of all days are low-production days, the researchers found that Texas could face a daily energy drought for up to four months straight. Batteries would be unable to compensate for a drought of this length, and if the system relied on solar energy alone, the drought could be expected to last twice as long — for eight months.
