A huge amount of the losses are waste heat from generation, be it turbines or reciprocating engines. Perhaps this argues for more use of the waste-heat.
I would also think that in some industrial locations, local Combined Heat and Power (CHP) Co-Generation plants might be very useful to utilize the waste heat, though this can have it shortcomings and is not applicable everywhere. A common problem being having non-correlated need for heat versus electricity. I have personally seen a shared residential location with a natural-gas fired generator and several natural-gas fired boilers. It had been thought that the waste-heat from both the jacket-water and exhaust system could be reclaimed to reduce the use of the boilers.
However, the costs of locally generating the electricity with nat gas outweighed the electric costs from the local utility even when the heat was needed. The generator is now used for power outages and some summer peak-shaving. This was a single 1500kW generator, so very small-scale. This is not an easy solution.
The most interesting setup I've seen is a food production facility with a waste digester feeding a CoGen engine with a Natural-Gas and Digester-Gas blend up to 50%. Perhaps better urban/suburban planning could result in centralised Sewage Digester waste-gas Co-Gen plants?
