Our bodies are constantly bombarded by energy in the form of waves (radio, cellphone system, solar radiation, electromagnetic, etc.), I think all of them are doing something to us and thus we need ways to filter or channel them.

Wireless electricity, yes it needs a lot of energy, but then what we need is a type of "wireless conduit or guide". Think about a laser, it's concentraded light, which can be diverted using a magnetic field. Maybe we don't have to transmit electricity per se, it could be wireless energy in some other form and then convert it; I think how we direct it is key.

The future always holds interesting options, discoveries are coming by way of the Large Hadron Collider and there's still things to find out about electricity in it's purest form. Just take a look at some of those super slow-mo lighting videos... Before lighting happens, "streamers" come down looking to connect with "spikes" coming up from the earth and things, what the hell!? Hmmm...if we come up with a way of producing and directing our own streamers and then spikes that match those...
