Power lines can pose a big problem when it comes to wildfires. The northern California town of Paradise was obliterated in 2018 by a fire sparked by a power line. Now electricity company PG&E says it will bury 10,000 miles worth of their lines underground. But that only accounts for about 10% of their total lines. The project is expected to cost between $15 and $30 billion.
