I have heard many times about supergrids and distributed generations (small scales generation connected close to the loads). In a supergrid scenario, a efficient and clean production of electricity (for instance wind farm plants) can travel long distances and be consumed even in a far different country. However, the distributed generation approach suggests that the generation shall be produced near it is consumed.
Both concept seem to be trendy for future electric systems, but, is not there a contradiction between the two approaches because while one is encouraging to export energy long distances the other one suggests to minimize the "travel" of the electricity from the generation to the consumers? is my understanding mistaken and there is not such contradiction?, and if not, which of them is more sensible for future grids?
