Put aside hydro power generation. Focus on electricity made from non-hydro renewable projects: wind, solar, geothermal, biomass.
The USA is number 1 in the world in the total amount of electricity generated from non-hydro renewables. The US generates 70% more electricity from such sources than the globe's number 2, non-hydro renewable power country--Germany. All data at: www.eia.gov/energy_in_brief/renewable_electricity.cfm.
Though Germany trails the USA in total power produced from non-hydro renewables, Germany does get a higher percentage of its power from such sources--approximately 20%.
Including hydro, the USA gets 13% of its electricity from renewable energy. But non-hydro renewables provide a bit more than 5% of the USA's total electricity.
Now bring back hydro into the analysis. Where does the USA rank in renewable electricity production, when hydro is included? Number 2.
With hydro included, as a result of massive hydro projects, China leads the world in producing the most electricity from renewable energy resources.
