f you were running a race, and you passed the person in 2nd place, what place would you be in now?

Pronounced as one letter,
And written with three,
Two letters there are,
And two only in me.
I am double, I am single,
I am black blue and grey,

I vanish faster when I am thin
and slower when I am thick
The wind is my energy
What am I?
