How do you know? I actually don't see how even one milliwatt of it could be "wasted": Even if it arrives in the midst of the ocean, this milliwatt is still heating the water, which allows for clouds, which gives us rain, and life.
The only possibly wasted energy is the rays the Sun sends to the nil, and maybe artificial satellites could grad a piece of it.
