熄燈:我們當前電網時代的漏洞和脆弱性再次在不利的情況展示
Lights Out: The Vulnerability And Fragility Of Our Current Electric Grid Time And Again Is Showcased In An Unfavorable Light
July 26, 2018
We are too much dependent on tools that can multiply our strengths while covering up our weaknesses. When technology fails, those strengths disappear and our weaknesses are laid bare before us. When this happens we must cope with it one way or another. Society has become so fragile today that the coping mechanism of most people is a distant memory relegated to our forefathers who could convert a four legged creature into their next meal.
Coping is a matter of knowledge and equipment. The more of both that you have in a situation, the more coping ability you will have. Ever wonder why a soldier heading off to war is so cocky? Knowledge and equipment. If you have good equipment and know how to use it your confidence is through the roof when something happens. It gives you the sense of control you need to overcome obstacles. Of the two, knowledge is by far the most important item to have. You may not have any equipment but if you need to start a fire and know 10 ways to do it without matches, you will eventually find what you need to make it happen. Knowing what to look for is the key to overcoming that obstacle.
When the power disappears and you are left with a room full of electronic paperweights, you need to have the knowledge and equipment to move to the next level of sustainability to cope with the problem. On one end of the spectrum you have full service, full bore idiot proof electrification to do most of your thinking for you. On the other end of the spectrum you have the clothes on your back and the mush between your ears with the power of a small appliance bulb. Knowledge turns that small appliance bulb into a finely tuned laser capable of destroying any obstacle. With the proper knowledge and equipment you can maintain your sustainability near the upper end of the spectrum no matter how bad it gets.

There are different levels to preparing for loss of power. It can go from a temporary loss for a few hours to total loss of all electrical equipment for years. The greater the problem is the lower down the levels you will go making sustainability more challenging. The following levels will deal mainly with power concerns so only brief mention will be given to food, water, sanitation and security concerns.

Level one – normal operations with full access to electrical devices and power

Level two- disruption of power systems for less than 24 hours

Level three- loss of power systems up to two weeks

Level four- loss of power systems for two weeks or longer

Level five- catastrophic destruction of power systems and some electrical devices

Level six- catastrophic destruction of power systems globally along with most or all electrical devices

Level one- All systems are functional and nothing out of the ordinary is experienced. All creature comforts are available and accessible.
