Science of the Electric Grid – Switch On Shorts – Video

Summary

This video examines how electricity reaches people in the developing world, covering centralized grid expansion, solar microgrids, and small off-grid systems. Students see why the grid looks different depending on geography, population density, and economics, and how rural communities are accessing power without waiting for the grid to arrive. Appropriate for high school Earth science, environmental science, or an introductory energy unit.


Expanding the electric grid can bring electricity to people that don’t have access to it. This requires generators, power lines, and payment systems. Most of the rapidly growing urban centers around the world will receive energy from the electric grid.

It could take years for grid electricity to reach millions of people living in rural areas, so small solar panels, batteries, and efficient electronics are becoming a solution that is affordable and available to people living off the grid.
