• Cuba's national electricity grid collapsed, causing a nationwide blackout.
• The outage is part of a series of blackouts exacerbated by aging infrastructure and U.S. sanctions.
• Residents express frustration as everyday life becomes increasingly difficult.

The national electricity grid in Cuba collapsed on Sunday, leading to widespread outages across the island and plunging around 10 million residents into darkness. The state-owned Electric Union (UNE) reported the failure on social media but did not specify the exact cause, the extent of the blackout, or when power would be restored, according to Reuters and Al Jazeera.

This collapse is part of a troubling trend, as Cuba experienced three nationwide blackouts within the month of July alone. Previous outages were attributed to problems such as damaged transformers and inadequate generating capacity, with authorities struggling to provide timely electricity, according to South China Morning Post and Al Jazeera.

Fuel shortages and an aging energy infrastructure have compounded the issues, with many power plants over 30 years old and receiving limited maintenance. The U.S. oil blockade, which severely restricts fuel imports to Cuba, has left the country struggling to meet its energy demands, as reported by Reuters and South China Morning Post.

The ongoing energy crisis has disrupted essential services such as water supply and medical care, straining daily life for Cubans. Residents have expressed their frustrations through protests, showcasing the severity of the ongoing crisis, according to South China Morning Post and Reuters.
