Centralized power generation has a 7 ¢/kWh cost disadvantage compared to distributed generation. In other words, if your solar rooftop can generate energy at 10 ¢/kWh, your centralized utility power plant, to offer you a better deal, would have to generate power at 2 ¢/kWh. No resource-based centralized power producer can generate at that cost, no matter how subsidized it is. Not gas, not coal, and certainly not nuclear or diesel.
