The way past your motion detector ...

The way past your motion detector.

It almost seems as if a motion detector has found its place in every house these days. He is also practical in his function. You can find the door lock better and prevent you from stumbling over a step when entering or exiting. But you can also scare away the unwelcome guests with it. A product with many faces. You can get simple models in hardware stores for as little as 10 euros. Installation is easy and comes in a wide variety of designs. A series can be found with a battery or controlled by smartphone, integrated into a Hue network from Philips or Bosch.

 

Do you go for a walk in the evening or just go out with the dog again to do something for your health after a long or boring day. Welcome to the club. This is what happens to many people day in and day out in Germany and elsewhere in the world. Now the following has struck me on my way. Although you are still far away from the entrances and on main roads or public roads, the lights go on permanently. On a distance of 200m there is an area where the motion detector hits 8x. But something like that too. Of course, if you want to do something good for your electricity seller, you don't have to change anything. This little story hides a little idea that enables motion detector owners to get an overview of how great the potential is if you pull the lever and extrapolate this problem to an entire country.

 

First of all, you have to ask yourself, was the motion detector installed by someone else, i.e. by an external service provider, or was the proud husband who works as a craftsman the superstar. How and who can only you know. If you have bought a motion detector that has a swivel head, then it is easy to fix the problem yourself. You can stand too far in front of the door and simulate the passing of others. The motion detector shouldn't go on just because someone is walking past on the sidewalk. That's why there is street light, also known as lantern light. After a few to and fro and toggle it on and off, the problem should be resolved.

 

If you don't have a motion detector yet, you can take care of it. A swivel head and a sensor that triggers the light of a better quality should be installed. A timer is also important. It can be set manually, usually with a coin, as the individual needs are. Should it be 1 min. to be 2 min. or better 3 min. when Aunt Trude comes home with the rollator.

So far so good. Tell your neighbors about this simple story, they will also have a motion detector that is set too generously.

 

After a few facts, here are a few figures and key data.

In Germany there are 1 million streets and around 40 million households.

My example is based on an estimate. In every street there are 100 motion detectors which are falsely triggered 3 times per night. Are triggered by passers-by. On average, a light is 2 minutes. on in my bill. A light consumes 1 watt. So that makes 3 watts per motion detector per night. Now we have 100 per street that is 300 watts. I only included 10% of all roads in my calculation. That means not 1 million streets but 100,000 streets (100K). There are also 100 motion detectors in 100,000 streets.

In numbers to make it short:

3 watts per light x 100 per street x 100,000 streets = 30,000 kw x € 0.30 = € 9,000 per day and per night. € 9,000 x 30 days makes € 270,000 per month x 12 months makes € 3.24 million. In the CO2 balance it looks like this:

 

This creates an additional burden of 1,082.7 tons of emissions per month.

Per year = 12,992.4 tons of emissions.

(The underlying resources that were used to produce the electricity are based on a third of the energy mix.)

If a third of all households have a pure green electricity seller, i.e. from water, wind or sun, then the balance is of course much better. Incidentally, it is also worth switching to green electricity here, so that coal-fired power plants, which are proven to be real climate killers, are promised an end. China in particular, but also neighboring countries such as Poland, have far too many of these power plants. After all, China has already written the plan to stop building new ones and closing others.

 

My bill is structured in such a way that it could only be half as high, but in return it could also be up to four times as high.

If you convert this to a citizen, i.e. to a household, then you only get 1-3 euros per year in additional costs. That sounds a lot more pleasant and so cheap that half of all households say, oh, at 1-3 euros it's not worth the effort. The electricity sellers are of course pleased.

From 3 million euros you can only pay 10x manager salaries. That doesn't matter that much. Did you know that Germany now produces so much surplus electricity that it has to be given away in large quantities on the electricity exchange! The surplus of electricity then also applies to other countries - not only does this country produce too much. This is how the drop in prices comes about. With the increase in real-time electricity production that can be optimized in real time, it is true that today can be better controlled so that electricity production is reduced at high load, but it still takes time.

 

While one is producing electricity

from 1-2 cents p.kw. Going out on good days, a small part of it gets stuck with electricity sellers, but that is more of an exception. On the other hand, one wonders why this surplus cannot simply be pumped into regions where electricity is hardly and not at all available. The cables that would have to transport it cost a lot of money and the loss of electricity over many thousands of kilometers is very high. It could also be distributed free of charge to the low-wage sector, but there are no storage modules there that could absorb excess. Surplus wherever you look. A phenomenon of this century.

 

Back to the core.

If the initial situation were different and the electricity sellers would tell you, do and do, that the motion detector only switches on when it is really supposed to and the money saved, if kindergartens and other facilities benefit then everyone would be there. In a society that doesn't behave socially among each other, it is still chic to support social projects, isn't it? But such an action would first have to be brought up with the available media and resources. You can deal with the matter once. Business-minded people could work out a working model that would adjust all motion detectors nationwide due to this fact. That would create new jobs in the short term. But to be honest, the "Do it Yourself method" is the smarter choice.

 

Now, of course, you can take even more time and extrapolate to Europe and the rest of the world. With a little research and the right data, you can definitely see how many units are sold per year and how many of them start up at night in heavily frequented regions.

But my job is done for now.

 

30,000 kilowatts fizzle out every day. This means that 1000-3000 households can be supplied with electricity per day.

If you were to do everything right during the installation in the future, you would not need any corrections afterwards.

 

In times of regenerative energy through sun and wind, such a small problem seems to have become much less important. In total, however, 11 million kilowatts have come together over the year.

The 11 here beautifully symbolic as the number of soccer players on a field. The sport that has captivated Germany for many decades.

There are definitely 100 other corners where more electricity is wasted, but still a badly adjusted motion detector is a component in the whole machinery of waste. You have to start with something, don't you?

 

Kind regards
