Your contribution points can be found in the top-left corner of the screen. It is the little medal where it says 3/380 in the screenshot. The left is the points you have left to invest and to the right is the total. In my picture you can see that I have 380 contribution points in total, all except for 3 of my points are invested.
To the left of your contribution point is your energy, the icon is a flexing arm. As you can see, I have 322 energy, of which 322 energy is available to spend.
