“One aspect to photovoltaic power generation that is NEVER discussed is: it is desperately vulnerable to terrorist or vandal attack. All you need to do is break a few panels- and major disruption of service can follow, as the system gets unbalanced. Can you buy or build a weapon that will break windows over a fence and 200 yards away? Oh, yeah, easy.”
Another issue re vulnerability of solar panels, PV or Thermal capture, is that of deterioration of output due to panel surface damage. I can remember my grandfather telling about seeing cars coming out of a Mexican desert road after a sand storm. All of the paint had been sand blasted off of one side of the cars and the window glass on that side was frosted by the force of the sand. Although it should be possible to protect the surface of solar panels by changing direction or covering the surface during inclement weather, I have not seen this discussed by solar energy advocates.
I just finished watching a film on the US dust bowl and it reminded me of this problem:

Didn’t find an appropriate category for this so I am putting it in the general dump category.
The world is full of plastic waste, much of which is non-biodegradable. Two young fellows have developed a substitute made from mushroom mycelium and grain waste such as rice hulls.
If there is a more appropriate section for this post, please point it out to me. A section called renewable resources might be useful for this.
Good post Ash, sensitive and timely.
The graphs speak for themselves. As prisons became privatized, the number of inmates went up. I highly recommend the video “Prison Valley” for an overview of the situation in US prisons. See: https://prisonvalley.arte.tv/?lang=en
You can sign in as a guest and need to “continue the journey” periodically or go back to video.
The top 1% are suggesting that they privatize state prisons as a means to solve State debt problems. This is pure evil. Already the US has one of if not the highest prison population in the world.
More on Greek possible default. https://hat4uk.wordpress.com/2012/02/16/greek-default-plan-jp-morgan-also-possesses-it/
“So what is the conclusion? I think there is a real chance now that Greece does suffer a hard and messy default and that financial markets could suffer a serious wobble if it occurs.”
Scuttlebutt on KD’s site suggests the same conclusion:
