Small Effects Consistency

The crux of the global warming position is the assertion that the small amounts of human inputs into weather systems via pollution of various types are sufficient to measurably change the weather. It occurs to me that nobody ever really gives us the relevant % that human activity contributes to these systems. The reason to want to know that number is to examine proposed large human projects and see if their effects will trip the threshold. For instance, how much of the earth's surface can you cover with solar cells before you start affecting the weather? Will it be a warming or cooling effect? How much energy can you extract out of wind, tidal surge, or river current before you achieve the same altering effects?

Are renewable energy sources really the environmentalist free lunch that everybody makes them out to be. It would be painful to find out that we've ripped out our infrastructure to make room for vast "green" energy structures that had their own nasty climate forcing effects. It would not surprise me in the least to find near zero studies on the subject.
