Exactly.

This is good for PG&E because it can't be blamed for wild fires. The wild fires will still continue to happen only now it will be the set remaining causes:

(lightning, car exhaust systems, campers' fires, arsonists, ...)

It's NOT primarily or even remotely Global Warming however. California has a fundamentally dry climate the intrinsically assures wild fires will occur. Expanding in wild fire prone areas is a direct result of real estate booms and costs, which are primarily high for artificial human reasons such as NIMBYism, greed, real estate as investment, etc.
