Franz Rottensteiner's View From Another Shore contains a story entitled "A Modest Genius" by Vadim Shefner , which does cause the whole world to grow dark. It is a collection of short stories which was published in 1973, which matches your timeframe.
Here's the opening to that story:
Sergei Kladesev was born on Vasilyevski Island, Leningrad. He was a strange boy. While other children were making sand pies and building castles, he was drawing sections of odd-looking machines on the sand. In the second grade he built a portable machine, powered by a pocket flashlight battery, which told each pupil how many good marks he would receive during the coming week. Grown-ups considered the machine uneducational and took it away from him.

Liussa went to the window and looked out. "Sergei, what's going on?"
she asked in astonishment. "It looks as though an eclipse is
beginning. The whole island is in dusk and it's getting dark in the
"It's now dark over the whole earth and even on Mars and Venus. The
machine uses a great deal of energy."
