Puerto Rico is getting its first off-grid, 100% solar-powered EV chargers as the rising number of natural disasters pose a threat to the territory’s vulnerable grid. [pdf]

At least 1.2 million power customers in Puerto Rico remain without electricity on Thursday afternoon after an overnight fire at a main power plant caused the biggest blackout so far this year acros. . At least 1.2 million power customers in Puerto Rico remain without electricity on Thursday afternoon after an overnight fire at a main power plant caused the biggest blackout so far this year acros. . A large fire at an electrical substation for Puerto Rico's new electricity provider, Luma Energy, knocked out power for hundreds of thousands of the island's residents Thursday. [pdf]
Puerto Rico faces a critical time to determine its energy future “Our power goes out in the afternoon, at night, sometimes various times a week,” said a resident. “Our patience is running out.” Víctor Santana installed rooftop solar panels on his home in San Juan, Puerto Rico.

They have respectively taken over the island's power transmission and distribution system and its power generation units, which have been owned by the Puerto Rico Electric Power Authority, the bankrupt public corporation that was solely in charge of generating energy on the U.S. territory.
Luma is expected to submit a proposal about how it plans to permanently rebuild Puerto Rico's power system which will go through a public comments period, hearings and approval by the island's Energy Bureau. "Realistically, our system can be rebuilt one more time within our lifetime," Velázquez said.
Puerto Rico should prioritize rooftop solar systems and microgrids to reach its renewable energy goals instead of building large-scale solar farms that might put agricultural and protected lands at risk, according to the study.
Meanwhile, Rojas and other power customers in Puerto Rico have been subjected to seven electric rate increases over the last year, even though people in Puerto Rico already pay about twice as much as mainland U.S. customers.
Even before Hurricane Maria, Puerto Rico’s electric grid was well below utility reliability standardswas also allowed to deteriorate due to financial mismanagement, eventually resulting in a 10-billion-dollar bankruptcy in 2017, which today remains unresolved in arbitration.

The reef systems of New Caledonia are considered to be the second largest in the world after the Great Barrier Reef of Australia, the longest continuous barrier reef in the world with a length of 1,600 km and its lagoon, the largest in the world with an area of 24,000 square kilometers. This ecosystem hosts along with , the world's most diverse concentration of reef structures, 146 types based on a global classification system, and they equal or even surpass the much larger. [pdf]
