I usually ride almost flat terrain. When lookingbfor wheels I see that a 50mm wheelset is heavier then a 24mm set.
I now ride a 35mm ALU set with a weight of 1560g. Seems quiet weird to but a 50mm carbon set that 100g heavier, or am I wrong in this?

Why cant shimano make them lighter? Do they want riders to buy the more expensive tubulars? Are they afraid rims wont hold if they make em lighter? Once a wheel is rolling a heavier rim will continue rolling more easily so is it necesarry to make the rims a lot lighter?
It is natural for deeper wheels to be heavier, there is more material on the rim. Farsports rims have full carbon construction and thus lighter.
MisterNoChain, the tubular is easier to design by nature and does not need walls that need to resist the tire pressure. The tubulars are a closed profile and the braking surface is supported by the rim bed, unlike the clincher braking surfaces. Ergo tubular rims are lighter than clinchers, mostly.

My main use for the bike is my 3x times per week commute of 30k.
And at 6 o'clock in the morning, I want to spend a minimum of energy.

If it isn't the weight , could it simply be hub quality that is slowing me down? (Drag in bearings, ...)
To get the same speed, I notice that I need more power then on my previous bike.
Geo and weight of the bikes are about the same.

However, its more likely due to your position on the bike, if in fact you are going slower...It's hard to notice differences by feel, really. Barring a wind tunnerl, or properly calibrated power meter and riding a known course multiple times with comparable wind / weather its almost impossible to gauge accurately. Much like in a car, you can feel faster by being lower, which might not in fact be the case. Changing out the whole bike, and trying to attribute your perception of speed to the wheelset alone is going to be a futile exercise.
You can also look at tires/tubes, and tire pressures, which have some bearing on speed, though more so on your perception of speed. Often times, a faster tire/pressure combination will feel slower, as its smoother.
