Hi Judy.
Thank you for your very thought-provoking post. Sorry it has taken a little while to get back to you, but I wanted to be sure of my facts before replying.
It's going to be a long one, folks. There are a lot of complex issues here.
So here goes.
Everyone, please stay with me. Fasten your seatbelts. It's going to be a bumpy ride.

First let me disclose that I don't own any PG&E stock, and don't have any interest in siding with PG&E in the current situation. At all. None.
Secondly, I will be using "you" in my response. Please understand that "you" is not directed at you, Judy,
at all, but it is just easier to use this term in a longer post, like this one.
I do not intend any negativity towards you, personally, at all. NONE. I do apologize in advance if I somehow offend.
I am just using "you" in the collective sense: all of "you" out there reading this post.
Having said that, so far as I know (and I did a bit of research on this - just to be sure - but as of today, January 6, 2019) the cause of the Camp Fire is still under investigation. This can, of course, change - but as of today, this is how it currently stands: the exact cause of the fire, and the (perhaps) responsible party, is still unknown as the investigation continues.
At the present moment in time, so far as I can determine, the only people blaming PG&E for the fire are media folks (hoping you will tune in to the 11 o'clock news) and hungry attorneys. Do a Google search on "Camp Fire Attorney" and you will see what I mean (
"PG&E May Have Caused the Camp Fire. We Can Help You File a Lawsuit") There are many
pages of links posted by hungry attorneys to be found with a simple Google search using this query.
To fully blame PG&E for this incident, is to not take into account - at all - the, um, shall I say "weather change" that has taken place, and continues to take place, in not just California, but most of the western states: significantly shorter rainy season (see my previous posts on this thread), with significantly less rain, significantly longer summer with significantly higher temperatures. Call it what you will, a name for it doesn't matter. What really matters is that this change is real, and it IS happening.
With this weather change in mind, it might be helpful to remember the cause of the Carr fire, of earlier this summer (August, barely more than two months before the Camp Fire), which burned parts of the Redding, California, area. The Carr Fire was responsible for three fatalities.
This from Wikipedia:
https://en.wikipedia.org/wiki/Carr_Fire"The Carr Fire was a large wildfire that burned in Shasta and Trinity Counties in California, United States. The fire burned 229,651 acres (92,936 ha; 359 sq mi), before it was 100% contained late on August 30, 2018. The Carr Fire destroyed at least 1,604 structures (at least 1,077 were homes) while damaging 277 others,[1] becoming the sixth-most destructive fire in California history. The fire was started when a flat tire on a vehicle caused the wheel's rim to scrape against the asphalt, creating sparks that set off the fire."So far as I know, there are no plans to sue the owner of this vehicle for starting this fire.
Then there was another incident, in Dobbins, California, closer to where I used to live. I remember this fire well, it was close enough to me that had the winds changed, I would have been toast. Fortunately, they blew away from me and the fire only came to within about five miles of me.
Dobbins/Oregon House Fire Protection District
http://dohfd.com/Dobbins%20OH%20History2.html"Yuba Fire August 14, 2009. This fire was started by a Red Tail Hawk flying into a powerline. The fire burned for 9 days eventually consuming 3,891 acres and two structures. Forty-one people were injured as a result of this fire and hundreds were forced to evacuate their homes or recreation areas." The hawk was never considered to be a plaintiff in this fire. The hawk was dead.
The point I am trying to make here is that fires in the West, and in California specifically, can be started for any number of reasons, both known and unknown. Had they not found the toasted hawk below the power lines after the fire was over, the cause in this incident probably would never have been known.
The other point is that PG&E has deep pockets. When a possible deep pockets plaintiff is considered, the attorneys come out of the woodwork.
Hawks don't get sued. Hawks don't have any pockets at all.

First, let me state unequivocally that I am not aware of any urban-interface wildfires that have
ever been started accidentally by a "power company worker". None. Never. There is, of course, the possibility that one has been so started that I am not aware of. But I am not aware of even one.
Hrm. I have lived in California most of my life (since I was three years old). Nearly seven decades. During my lifetime I have watched urban-interface wildfires without number scorch my state. As I have stated in earlier posts on this thread, urban-interface wildfire is a fact of life in California. As are hurricanes in the south east United States. As are tornadoes in the midwest.
During recent years it is impossible not to notice that the number and severity of these wildfires seem to be increasing. There is persistent drought here in California, and in the west. I'll call it "changing weather patterns" for the time being.
Fires start here in our western wildlands for reasons both known and unknown. Arcing on high-tension wires can - and do - cause fires when no one is around.
Here are a few examples:
This is a high-tension power line. Notice the large sparks falling into the underbrush. I don't think this one is in California, but if in ultra-dry California, the ground under the line would have needed to have been scraped down to bare dirt to prevent a fire in dry underbrush.
https://www.youtube.com/watch?v=nTWc45JRQGsIt's not clear from this video what cause the arcing. It could have been high winds in the area, causing the extremely heavy electrical lines to sway, maybe coming just close enough to cause an arc. Some of the wind gusts in the Feather River Canyon on the day of the Camp Fire were in excess of fifty miles per hour.
Note the size of the sparks, raining down onto the ground.
Here's one where a tree is brushing against a power line. Imagine if this had happened in the dry Sierras:
https://www.youtube.com/watch?v=HvRWTGqQAoAHere is another. Although it is difficult to tell, it appears that something very briefly flew across two lines, causing an arc.
https://www.youtube.com/watch?v=q1wsAd9q_4wNot too difficult to imagine, perhaps, a small tree branch hurled by 50 mph winds across two power lines in the Feather River canyon, causing those lines to arc.
Here's one of a couple of vandals intentionally causing a short in overhead power lines - and a fire below these lines.
https://www.youtube.com/watch?v=-4faw3xBgG4If a major conflagration had been caused by this "bit of fun", the cause likely would never have been known. The evidence would all have been burned, and the perpetrators long gone. Probably still laughing.
Whether by errant car rims, hawks, arcing or intentional vandalism (or any number of other reasons): fires in California happen. And they have been happening for hundreds of years.
JudyJB wrote:In Michigan where I am from, most residential power lines are buried underground, so I was surprised to see so many above ground in California and the west. Putting wires underground at least reduces lines being knocked down in storms.
Most, if not all, of electricity in Michigan is generated by coal, nuclear fission, and natural gas.
https://www.sciencemi.org/energy/alternating-currents-how-michigan-electricity-is-made/Although the largest proportion of electric generation in California is by natural gas, a significant portion is also generated by water being run downhill through hydro-electric plants.
In order to run hydro plants, water must run downhill in order to turn the turbines that generate the electricity.
I'm speaking here specifically about the hydro-electric "Stairway of Power" in my area of Northern California that is based on the Feather River and it's tributaries. The Camp Fire started in the canyon carved by the Feather River.
Here is the long version:
https://www.wplives.com/frc/stairway_of_power.phpHere is a schematic of the "Stairway of Power"
https://www.researchgate.net/figure/Schematic-of-the-Upper-North-Fork-Feather-River-Project-and-other-PG-E-projects-on-the_fig2_327253918showing how the water source originates at the Mountain Meadows Reservoir (at about 5,000 feet above sea level) and runs downhill (the same water powering many different powerplants) as it flows all the way down to Lake Oroville (at about 900 feet above sea level - a four-thousand foot drop in elevation from the top of the "stairway" to the bottom).
"Pacific Gas and Electric Company operates in the famous scenic Feather River Canyon a descending "stairway" of powerhouses which utilize the water over and over for power before it flows on undiminished to other uses."Here is a really cool graphical map that you can use your mouse to enlarge, which really brings into focus this "Stairway of Power".
https://www.arcgis.com/apps/MapJournal/index.html?appid=99455176635b43138f40d66ca21ff87aThis is the short version:
First, take note of the fact that this hydro system is located in a fairly remote, fairly rugged area of the Sierra Nevada mountain range, from the upper elevations to the lower elevations.
Secondly, the Sierra Nevada is mostly composed of solid granite, with a few odd bits here and there of ancient volcanic rock.
There are mostly no roads into this area, except for Hwy 70, mostly a narrow, two-lane road that was carved into the side of the canyon for much of it's length. Steep cliffs down to the river on one side, steep cliffs up to the tops of the ridges on the other. Very few places to pull over and stop, very few places to turn around.
I know Hwy. 70, I have driven it in the Feather River Canyon more than once. It is not uncommon for transmission towers to be brought as close to a site as possible, with the remainder of the distance transversed by helicopter to the top of a ridge.
The only way power lines - and these are not "residential power lines", but are rather many-armed steel towers, maybe fifty feet high (or more), that are transporting mega-watts of electricity from the canyon power plants in the Sierra down to the valley.
It is thought, perhaps (and only perhaps - the investigation is not yet done) that a tiny insulating ring on one of these towers might have failed in the 50+ mph winds that were blowing through the canyon on that day.
I'm not an engineer, so I don't know what all would be involved in attempting the probably impossible task of burying these lines. Think steep-sided ridges of solid granite, these towers linked together along the top of these ridges.
A backhoe couldn't do it. A jackhammer might. But a jackhammer is not practical for burying mega-watt capacity power lines that extend for hundreds of miles.
Sorry this is so long. I welcome everyone's comments.
Thanks for reading all the way to the end. I know it must have been quite a slog.
