Imagine you take a turbine in the Funny Game Family Game Style Gamer T Shirt , and give it some rpm (rotations per minute) via some motor or something. Now if we consider space as a perfect vacuum (although it is not, it contains roughly 3 atoms per cubic meter, but for the question purpose let’s assume), the turbine will keep on rotating even if we disconnect the motor (this is what newton’s first law of motion says). Now once you have disconnected the motor, again imagine(we have a lot to imagine, lol) that the shaft of the turbine is connected to some dynamo (in space) so that the rotational energy is converted to electrical energy. Imagine again that you have a wire /cable of infinite length and you use this cable to power you house, that is connecting you house with the dynamo by mean of this infinitely long wire to transmit power. Considering that the power produced by the turbine, even after the frictional and other losses, is still enough to power your house.
