How is California's aging power grid infrastructure contributing to wildfire disasters?

California's power grid infrastructure, originally built in the early 20th century, is fundamentally inadequate for modern demands and climate challenges. The system's aging components, including deteriorating hooks and power lines, create dangerous conditions where equipment failures can spark devastating wildfires, as demonstrated by PG&E's role in starting the Camp Fire when old equipment broke and showered sparks on the ground. The core problem lies in the utility company's approach of maintaining outdated equipment until it fails catastrophically, rather than proactively upgrading systems. This reactive maintenance strategy has proven disastrous in an era of increased climate stress and higher energy demands, highlighting the urgent need for comprehensive infrastructure modernization to prevent future fire-related disasters.
