How abuot we decenterise the power system so the power does not have to be moved as far. This would reduce the need for power mains except for industry. I think for many homes a solar/wind system could provide much of the needed power and that would also help reduce the load on the gird system. Keeping the power line right of ways clear seems to help as far as damage to the lines. Iknow it has helped around here. Putting as much as possiable underground would help but it is harder to service and so if your power does go out it will be out longer. Just a thought.
