Mining is used for ALL energy technologies. Thats a given - if you want electricity you need mining and space. This is why I think we need to radically reduce energy demand.
But about solar energy - I made a calculation here a while ago about solar power space needs and came to about a 3-4m diameter circle for each person including industrial energy needs (in Europe weather conditions). Here is now a study showing how it is for New York. It seems that by using just the rooftops, they could fill 1/6 to 1/2 their energy needs. And that is of course a city with plenty of skyscrapers - cities with lower population density could have 100%. http://www.nytimes.com/2011/06/16/sc..._r=1&ref=earth One constant is always that people put these megaprojects somewhere distant - on someone elses ground - where the lives of those who profit will not be impacted directly.
