Compared to this, extremely small, but compared to the overall economics, quite significant. Here is a chart of transmission losses from the source to the end

  End to end efficiency is absolutely critical for making any wireless power endeavour viable. Beyond delivery loss, don't forget that there are other CAPEX/OPEX considerations. For example, an underwater cable from an offshore wind-farm might be a more efficient means of energy delivery but it's installation and maintenance cost would be much much higher and require more time to deploy than a wireless solution. That is inevitably a significant part of any economic benchmarking.
