Japan is going to transfer energy from space to Earth as early as 2025. We are talking about the transfer of energy received from solar panels placed in space. Of course, without any cables.
There are few details about the project yet. It is known that it will be implemented by private companies with the support of the state. It is also reported that the project will involve small orbiting satellites, which will transmit energy in the microwave range to Earth.

In itself, the technology of energy transmission over the air is not at all new, but in the case of such a project, we are talking about distances of hundreds of kilometers. The Japanese space agency JAXA made a breakthrough in this area back in 2015, when scientists managed to transfer 1.8 kW of power, but then the distance was only 50 meters.
At the same time, even if Japanese scientists succeed, the technology of transmitting solar energy directly from space is unlikely to become widespread in the foreseeable future, since now calculations show that about 7 billion dollars need to be spent on generating only 1 GW of power in orbit, and how much of them will be able to deliver to Earth, and it is not yet clear at all.
