The benefits of having a common time such as CET/MEZ for most of continental Europe outweigh the nicety of having 12 noon correspond to the high point of the sun's arc in the sky.
(they stayed on CET/CEST after changing timezone during WWII)
UTC makes sense for Spain and maybe France, UTC+1 is a perfect fit for Germany and Poland could be UTC+2.
The vast support for permanent summer-time makes me think that either a lot of people are early birds or people just don't understand that DST is simply a way of forcing everyone to get up an hour earlier to "magically" get more sunlight in the evening.
If you don't like getting up early you should hate summer time.
Having grown in those hours I have to say it kind of sucks. You wake up in darkness most of the year. If you wake up at 7:00 local time, that means you wake up at 5:30 solar time.
There are loud voices (including psychologists and medical experts) that are advocating for moving Iceland back to Icelandic standard time (UTC-1). They claim the lack of sunshine can have detrimental effect on the sleeping cycle and therefor the general health of the population. Adding an extra hour of sun in the morning might be helpful for the general population.
Also smart: '“Member states should mull over together which time – summer or winter time – should be adopted on a permanent basis.”'
Let's keep it on summer time, having light at 4 pm is more valuable than at 4 am. (I know, exaggerating, but only a little)
