Except for the fact that you actually don't need any sort of energy infrastructure whatsoever with electricity. All you need will be a solar panel in the near future, resulting in more homes with heat and lights, more people with access to inexpensive transportation, and a more equitable share of well being. Third world countries stand to benefit the most from electrification.

Using photovoltaics for electric heat is a lot more costly than solar-thermal water heating, so you'll likely see a mixture of those two.
