Cuba’s power grid failed late on Sunday, causing another nationwide blackout, a state utility said in a social media post. Cuba has been suffering rolling power cuts due to aging equipment and a US energy embargo that halted regular deliveries of fuel for power stations. This is just the latest in a series of total collapses of the electricity grid. Just 24 hours ago, the whole west of the country went dark. The power cuts have made normal life almost impossible, with each outage also meaning that water supplies trickle away and ceiling fans slow to a halt.
