...and one less hour of morning light. It all balances out. I use the same light in the early morning as I do in the late evening... where's the "savings"?

You wanted to know the reason, this is it.

4 o clock in the morning I sleep. I do not use light when I sleep. When I wake up the sun is up. I really don't see if it is up for three hours or just two hours, but it is light then. I do save one hour of bulb light in the evening.

 

get them some hi vis jackets, you can't miss running one over then twisted:

 

I'll try to do it in a graph.

0---3---6---9--12--15--18--21--24
+---+---+---+---+---+---+---+---+
------+------------------------+---
------------+-------------------+--
----------+-------------------+----
Legend:
0 to 24 is the hours in one day.
Black: hour timeline.
Red: sun is down.
Green: sun is up
Blue: people sleep
Yellow: people are awake
Orange: people sleep (summertime)
light green: people awake (summertime)
You can see clearly that in the normal time schema, you need some electric light in de evening.
With summertime the wake wakingperiod falls in the light periode, so you save two hours.

For clearity I set sunrise to 4, wake up to 8, sleep at 23 and a shift of two hours.

During the winter the periode of daylight is far shorter than the number of hours people are awake. Shifting back or foreward does not have that big amount of effect

 

But you assume that people sleep/wake during those hours. That is flawed. Most people don't get up or go to sleep based on the sun anymore. They wake before they have to go to work, and they get to sleep in time to get up the next day. This might have worked back when more than 1% of the population were farmers, but it is no longer applicable today.

And again, studies show that there was absolutely NO energy savings with the switch last year, savings that they were hoping would happen... and some indicate that it actually causes energy usage to increase, such as in the state of Indiana: link 1, link 2, link 3

That third link gives good reasoning why energy use can actually increase with the implementation of DST... people are getting home during the hottest part of the day and using the air conditioner more.

 

You sleep at 4am, yes. But you are one person. Many others are awake before the sun comes up, and they're using electricity until then. Similarly, those who are up at night use electricity after the sun goes down. No savings.

You cannot overlook the fact that there was no energy saved when DST moved, neither here nor in Australia.

 

So, when did this light-hearted pool take a left-hand turn into the Twilight Zone?

 

Couldn't wait coud ya' ?
Who needs tomorrow when you can get their today

 

I'll bring it back down to Earth - 20th June for Mike

 

Wrong. I assume people get up at 7 or 8 in the morning. In my graph I used 8. But 8 in the winter is 7 in the summer (in real time, the clock still says 8 ).

I do not argue that it saved in reallity, I only gave the reason why they invented this phenomena in the first place.

Good point.

 

This...

and this...

contradicts in my opinion

 

Around the time that Tinus started about the pull of gravity and Jupiter, oh and the mere fact that we are in the off topic forum helps.

 

Hey, I had no choice! The threads were sitting there, waiting to be answered!

 

How does saying that people who are awake before the sun comes up and sleep after the sun goes down contradict the statement that people don't wake up and fall asleep based on the rising and setting of the sun? The statements support one another. If people got up and slept based on the rising and setting of the sun, they'd be up around sunrise and down around sunset. But that doesn't happen.

So, again, I ask: why do DST? It creates no energy savings.

 

Might be different in the Netherlands, but people in the US don't get up at 7 or 8 in the morning. Most have to be at work or school by 7 or 8 in the morning. I don't get up until 7:30, but I stay awake until the early-morning hours, so I'm burning the light that I "saved" by getting up late.

I already know why they invented the phenomena. What I'm saying is that their reasoning is flawed.

 

Funny, sounds like an addiction to me

I'm still sticking with the earlier prediction:

 

I quit this discussion. It wil be a repetition of moves.

 

It won't be repetition if you can show me what the justification is for keeping it (not what the reason was for instituting it in the first place). ;)
