No, even if it was possible to beam energy with 100% efficiency...
it's still energy. It comes down, it must get out. If not, Earth gets
cooked.

Hell on Earth, the nightmare of science fiction, brought to us by
those that try to save the planet. Isn't this the scenario of some
cheap sci-fi, where the Mad Scientist tries to destroy the Earth by
placing an enormous mirror or lens in orbit, concentrating solar
energy?

Just we don't need mirror or lens, place a lot of death ray
satellites. Sorry, power satellites.
