Macbook Pro and iSight makes me paranoid

no, what would it be doing, and what resources is it using?

anytime i've ever come across a website that wants to use it it asks me it doesn't just turn on.

There's also a nice little light that comes on when it's in use.

 

Yes it is possible, but unlikely.

If you really want to disable it, a cleverly applied screwdriver or awl will do the trick.

 

The camera is not in use when no application that needs access to it is accessing it, for instance iChat, Photo Booth, Skype, QT Player X, iMovie and some other. But as the iSight has a green LED besides it, you know, when it is running.
I have had iSight cameras since 2007 and I never got spied upon by any of them, thus there is not really a need to be paranoid.
Maybe have a look here to learn more about how to secure Mac OS X:

There are currently no viruses for Mac OS X in public circulation, only a handful of trojans and other malware, which have to be installed manually via entering the administrator password.
The only anti-virus you need to protect your Mac is education and common sense.​

 

If it's not on, it's not using any resources. It's only on if you launch an app that uses it. When it's on, there's always a light to indicate that it's on. If the light is off, the camera is off. There's no way for the cam to be on but the light off.

If you're concerned primarily about battery life, this should answer most, if not all, of your battery questions:
