AC or DC Power?
In the late 1800s, electricity as a public utility was available as direct current, or DC. Famous entrepreneur Thomas A. Edison held many DC patents. He desired to continue profiting from them. But that was later threatened—no overturned—by alternating current (AC) electricity.
The change has an element of justice about it, as Edison played the power game in unfair and cruel fashion. He publicly used AC to electrocute cats, dogs and other animals, such as horses. He wanted people to believe AC was too dangerous. He failed to mention DC was every bit as dangerous. Edison was a man of few scruples.
Alternating or Direct Current Power?
Today, many household appliances employ semiconductor devices. So they utilize direct current. Some household energy systems such as solar panels and wind turbines generate DC power. Could it be one day the world will convert to Edison’s DC power? The references below suggest it is a real possibility. But before you check those out, consider the video below.

NEXTEC is pretty innovative. I wonder why we don’t go to the direct current method sooner rather than later.
Granted, the video is primarily an advertisement. Still, it does raise some legitimate questions. DC power was pushed by Edison using less than reputable tactics. Did this mean that DC should never be considered at a future date, as needs change, simply because of those tactics?
It does seem odd that we need to convert a lot of the power coming into our houses into DC in order to use many of our devices!
