I think its mostly going to be a mixture of different systems, like natural gas, methane from biomass, various green power etc. One thing no one has mentioned is hydro power. Greenhouse gas emissions are very low, - even those 2 or 3 studies that have claimed that hydroelectric dams create greenhouse gases used 2 examples of very poorly done dams in Brazil.
Years ago I used to live in a rebuilt mill from the 1840's. The water was still dammed in a retaining pond, and went over a sluiceway. For this sort of system it should be relatively easy to put in a turbine system to generate power. Since all throughout the eastern US there are old dams left over from the old milling days, it may be a good alternative method of generating electricity. Even more so if the land (and dam) owners have incentives to install these turbine systems. That ought to go a long way towards reducing our dependence on oil and reducing greenhouse gas emissions.
