Is there any sense in that if i put on some more muscle size that muscle needs more energy to work thus taking some fat to burn that need. or iam i just wrong.
No, you're correct. That's why strength training is more important, expecially for someone who is just starting out. Unfortunatly it takes longer to increase muscle mass than it does to drop bodyfat. Which makes alot of people just starting out think cardio is more important than weight training.
Cardio is good because it helps keep motivation high by seeing fairly quick results, but that's only good for someone who realizes that fitness is a longterm goal(I know that sounds like a contradiction, but it just sounds that way
). It's bad because it'll make achiving their goals(which is almost always leaner and more muscular) take longer. Aswell as being more likely to give up before coming close to reaching their goals. Most of the best forms of cardio suck, and are just plain boring, even with a friend. Lifting can be far more enjoyable. You simply need to find how each persons` training routine should be tailored.
Do both cardio and strength training. split it into 2 routines if you can. I personally lift during my lunch break(I'm in the Marines, so there's always a gym nearby), and run about 3-6 hours later(usually finish off my earlier workout before I start running).
If you can't hit the gym twice a day, or have a time issue, lift first, do cardio with your remaning time/energy (Another advantage of splitting your workout is that you hit each one with more energy). For the most part, I don't spend longer than ~40 minutes lifting at a time, and it's usually closer to 30. I do this because I do alot of super setting or running super circuits on my routines, which wears me out pretty quickly.
That's me though, I train very focused, and don't talk to people when I'm working out. For you, that might make lifting too much of a chore. Alot of people need someone to workout with for conversation between sets, motivating eachother, spotting, form tips, or just plain company to make it more enjoyable.
