I'm sure PG&E, for example, would be willing to clear-cut forests near power lines to avoid shutdowns, but their operations are heavily restricted by people trying to be "green".

When they don't shut down power to bone dry regions with wind blowing trees into the lines, they face billions in costs when massive fires result. Instead of protecting their homes from wildfires, they expect PG&E to somehow prevent fires in the first place. But there are other sources of fires.
