You can’t really give many more examples than wireless. There is no way to make concrete that uses much less energy. No way to make steel. No way to heat or cool your home without using a lot of energy. No way to move yourself around to more than bicycle distance without expending vast amounts of energy on building infrastructure, vehicles (cars or trains), and powering them.

If the poor billions are to have any chance to live in any kind of comfort resembling what wealthy westerners or Asians do, they need to massively increase their energy consumption. There is no wireless way around it.
