For example at the end of the mission Citadel: Volus Ambassador, if you choose the renegade option, you will gain the Volus Bombing Fleet with a war assets value of 75 and lose 10 points in Turian Sixth Flee but if you choose the paragon one of saving the colony, you will gain nothing.
During the Grissom Academy mission choosing to use the students as Artillery instead of Support gives you 75 instead of 50 TMS, for a gain of 25.
After the Quarian/Geth war, if the Quarians are still alive, Tali and Xen argue about whether to prioritize ships for rescuing survivors or salvaging Reaper tech. The latter grants you Advanced AI Relays for 45 TMS, and seems like a "Renegade" option.
Just about everything else I can think of can be resolved with charm/intimidate or is better off with the paragon choice.
