We see that happening now with a species that we inherently think we understand. You throw tools at aliens, who likely do not think the way we do, and the results would be even more unpredictable.
Ah but, if an alien race had given us energy alternatives, none of the climate damage would have happened. We see in TNG they can actually control weather to a large degree. We are stuck continuing to pollute because our lives are based around it. The average person doesn't really want to pollute, but we really have no choice unless we "go green" and ride the bus. The average person has to wait for better technologies to be invented.
I disagree that species have to be enlightened someway to deal with advanced technology. It's not like the Federation would have to just drop off the tech and leave, they could stay as friendly advisors.
From the movie First Contact it really didn't seem like humans were all that enlightened when Cochrane invented warp drive. They just stumbled upon it and then learned to adapt. Their first action when seeing new life (data) was to shoot him with a machine gun.
