Critical Infrastructure News

Taiwanese officials are fretting about whether a severe outbreak of Covid-19 could jeopardize the island's critical role in the global semiconductor supply chain. But there's another threat to the industry that experts worry may have even more drastic consequences: the climate crisis.

Taiwan — which accounts for more than half of the world's output of chips — has been grappling for months with its worst drought in more than 50 years, an event experts say could become more frequent due to the effects of climate change.

"There is clearly pressure in the semiconductor industry," wrote Mark Williams, chief Asia economist at Capital Economics, on Thursday in a note that referenced the water shortages and coronavirus cases, along with rolling power outages.

Manufacturers around the world have already had trouble securing supplies of semiconductors, delaying the production and delivery of goods. If Taiwan is hit hard, the situation could become much worse, given the island's importance in contributing to global chips supply.

A fire at an electrical substation in Puerto Rico has knocked out power to hundreds of thousands throughout the island, utility company LUMA Energy said Thursday.

"The fire caused major blackouts across the entire island. The situation is under assessment and work is being done to restore the system," LUMA Energy tweeted, stating that restoration efforts will continue overnight.

About 400,000 customers in Puerto Rico were without power as of late Thursday, LUMA Energy said, which is more than 1 in 10 residents on the island.

The fire broke out in a transformer at LUMA's Monacillos substation, the company said. Personnel from the Puerto Rico Police, Fire Department and Medical Emergencies are at the scene and no injuries have been reported.

Calling it an explosion, Gov. Pedro Pierluisi said that both state and federal law enforcement authorities are investigating the cause.
