"A week after Hurricane Maria ravaged Puerto Rico, the US commonwealth's residents are struggling to survive without basic necessities as federal officials say aid is still on the way."

"A dam in Puerto Rico weakened by heavy rains from Hurricane Maria was in danger of failing on Sunday, posing a flood threat to thousands of homes downstream as the storm-battered U.S. island territory struggled through a fifth day with virtually no electricity."

"Environmental groups say they will sue Duke Energy for not telling the public what would happen if any of its dozens of coal ash dams fail."

"Hurricane Maria has dealt a new blow to Puerto Rico’s bankrupt electric company — knocking out power for the entire island and imposing costly repair burdens on a utility that was already struggling with more than $9 billion in debt, poor service and sky-high rates."

"As residents of the Southeast are returning home and assessing the damage left by Hurricane Irma, Florida scientists are anxiously waiting to evaluate the storm’s impact on one of the state’s most valuable — and vulnerable — ecosystems: the Everglades."

"As if loss of air conditioning and refrigeration weren’t bad enough, widespread power outages in hurricane-battered Florida are teaming with structural failures to cause another headache: sewage overflows."

"Utilities in the U.S. Southeast returned power to almost half of the homes and businesses knocked out by Hurricane Irma, leaving about 4.3 million customers in the dark as of midday Wednesday, in one of the biggest restoration efforts in U.S. history."

"As Hurricane Irma rampaged through Florida, snapping power lines and damaging vital equipment, it left as many as 15 million people in the state without electricity, the Department of Homeland Security said on Tuesday. While some homes may see power restored within days, utilities said that other customers may have to wait weeks."
