We would need a quantum leap in battery technology (reduced cost and increased range) and the will to implement it. Battery production and disposal is a very nasty business and is loaded with environmental concerns.Electric is the only real current solution
There is also the problem of our rare earth supply, mining rare earths causes massive environmental issues. Sadly, many green technologies require them.
The range problem could be solved with swappable battery backs, like with the upcoming Tesla vehicle. But, gas stations would need to have them charged and ready to go. The battery packs are not cheap.
Then, we also have the problem of trains, trucks and ships running on fossil fuels. We could spend crap loads of money and electrify the tracks and replace the locomotives with electric locomotives that draw the power from the tracks, but I am not sure if we could afford that or if it would be practical for freight. Large container ships could be nuclear powered, but we cannot risk those ships falling into the hands of pirates. Not sure how we could power semis with battery power.
Finally, we burn a good but of fossil fuels to generate energy for our homes, with current wind and solar technology, we could not hope to meet our energy demands at a reasonable cost. Just the other week, nuclear was deemed too expensive even with government subsidies:

That leaves us with fossil fuels (minus special areas where geothermal or hydro might be profitable on its own).
Would be nice to see a world of electric vehicles with it all powered by nuclear plants, but that is a dream, unless we have a massive technological breakthrough.
