Is it possible for a space city to exist in and draw power from a nebula? Any side effects?

For context, this takes place about 300 years in the future. The space city in question is located in a nebula, completely man-made (not build upon any preexisting foundations like an asteroid etc.), densely populated and continually expanding, and possesses a surrounding force-field in order to create a habitable environment within. It is isolated from the control of any sole government and is established as a hub for interplanetary diplomacy. Thus, it needs to be mostly or completely self sufficient, but does receive shipments of outside goods.

What I would like to know is:

• would drawing and converting power from developing stars within the nebula be a feasible way to power the city

• are there any dangers presented by this location either to the city or the ships traveling back and forth

• what steps could be taken to minimize or protect against such dangers
