Your question assumes that all energy is 'created equal'. Nuclear Power is sufficient for generating electricity, but does little for transportation. How do you run cars, boats, truck, trains, planes, tractors, etc?
As far as electrical power goes, Nuclear Power would be sufficient for 100's of years.
