Except for a sprinkling of off-gridders, we are completely dependent on networked energy and data.
If you wonder what the typical personal experience of the end-of-this-world will be like, it may well be this:
One ordinary day at no particular time, the power goes off, cellular service and Internet both vanish.
Most vehicles won’t start because their PCM is fried.
The interstates and many urban roads are blocked with dead vehicles.
Gas pumps won’t work.
The entire country is blanketed with full spectrum jamming from nuclear-powered satellites, meaning not even HAM operators can connect over distance.
There is no information available, there is no one coming to help or advise.
All utilities are down, nothing is moving, cities become death camps.
Most people die without ever finding out why.
That is the end of the world.
I forgot mention every plane in the air either crashes or crash-lands.
A few quick thoughts…
In this scenario (I’ll limit to the USA), 10-20% of the population is dead inside of 14 days . Those critically dependent on powered med equipment and/or meds to live. The initial (14 day time period still) pandemonium and associated violence get you to the rest of the my hypothesized %. The initial lack of water will be highly contributory to the violence, and the time of year is very important too in determining initial losses due to weather and other factors. Cities and parts of the ‘burbs will burn very quickly and become totally uninhabitable at the outset.
Bugging in won’t be plausible for ~60% of the population and you’ll have an initial 150mm+ wandering around with massive death occurring due to starvation, infection, medical emergencies, violence and suicide.
Dammit… I could go on and on, I’m getting called to dinner. The irony 😂😂
I know the answer but I know I wouldn't be one of them.
