I know I was not clear in what I wrote. I drive a hundred miles every work day. Fuel prices in NY are crazy so I always fill up at a station that is near to where I live who has the best prices anyway. So when my range shows that I have around 100 miles when I am home I have to fill up. It just happens that if I just drive to work and back I will have 150 or so miles left in the tank after 5 days. Of course it is impossible to only drive to work and back so I end up burning up that 50 mile cushion. If I start idling to warm it up at home and at work well I fuel up on the 5 day and not the 6th.
Not a big deal but when you go through as much fuel as I do, well you try to get the best MPG you can and the beauty of diesel is how long you can go between fill ups. Everyone can do what ever they want in terms of idling but for me it feels wasteful and probably a carry over from those days in the 60's and 70's where we were going to save the planet. It is still here by the way and doing much better that it was then.
When you consider the recycling of those garbage bags it probably is very similar. People do it because they feel they are saving the planet and not filling up landfills and some other such nonsense. We actually use more energy to recycle them than is used to just toss them out. And modern landfills are so secure anymore what goes in there stays there and I am sure at some point is going to one other source for energy and reuse of waste material for a new use.
Thanks for the data on idling because now when I am forced to idle I know that I am not burning all that much fuel and I think your math was a bit off because even at a high MPG I would have to idle closer to 12 hours to lose 100 miles off my range.
