A step in the right direction, but not the ultimate destination:
Natural gas tops coal as top source of electricity in US

A further step would be the long-term implementation of a mico-grid power structure in the U.S. -- which would use small gas plants for additional power and "green" sources (solar, wind, water turbine, etc.) for primary power. The "smart-grid" concept pushed by power technologists was not originally designed so power companies could bill your residential meter in 15 minute increments and screw you each billing cycle; originally "smart-grid" was focused on improving core power infrastructure and distribution. However power companies found there was more money in deploying smart meters than fixing their infrastructure.
At this point power companies are fighting tooth & nail against core smart-power grid proposals since they have a deep financial vested interest in protecting their existing large power plants and ancient distribution infrastructure. Any liberalization of the power market opens the door to new competitors deploying a smarter, more local grid with green roots which in time will likely be very price competitive. Of course large electric utilities are piling on political donations to stop any competitive power market proposal in the U.S. -- however the reality is that the long term future will be a more dynamic electric market and the big utilities are already dying dinosaurs - the vestiges of which will litter the landscape five decades from now.
