Nikola Tesla was a famous scientist who developed alternating current, the means of distribution for electricity for the vast majority of devices, appliances and machines in households and factories and just about every other electrified thing in the world today. 

But even as Tesla was inventing much of the technology used in the alternating current electricity supply system, another famous inventor, Thomas Edison argued that direct current was the best way to distribute electricity.

By the time Tesla tech came onstream, DC had already been in use for a decade, but within a relatively small area, and Edison lost that argument mostly because the components of an alternating current grid enabled electricity to be carried far and wide beyond the power generating facility.  [Read more…] about Electric power: Clean energy infrastructure driving switch from AC to DC
