NepaliBudho jyu,

I would rather worry about generating sufficient electrical energy, providing enough poles with lightning arrestors, properly sized fuse cut-outs and insulators and carrying adequately sized overhead lines at places. Distributing enough power to every house has already become a big of a deal. So, wireless energy transfer in a country like Nepal is out of the question.

Like bittertruth had mentioned, it can be done in future. It is way too early to think of that now.
