For transmitting information- pulse lasers and radio waves, antennas, that kind of stuff.
For transmitting power, there is no efficient way. Solar panels are pretty much the only way, and even then it's so inefficient they are only used to get solar power from the sun's EMR. No one blasts a laser at a solar panel to transmit power. We use cables. They work much better.
If we were able to efficiently transmit power wirelessly, we would probably have solar collection satellites beaming energy down to earth or recharge rovers on mars with beams or something.
