PASADENA: California's largest energy utility firm will bury 10,000 miles of power lines in a massive bid to prevent its equipment from igniting more deadly wildfires, its chief executive officer said on Wednesday (Thursday in Manila). Pacific Gas and Electric's (PG&E) faulty power lines sparked the deadliest blaze in the state's modern history, which swept through the northern Californian town of Paradise in 2018, killing 86 people. PG&E's equipment was again blamed this week for one of the largest fires now blazing in California - the Dixie Fire - after a tree fell on a power conductor on the day the blaze began.
