Copper pots have been discovered in Egypt with an iron rod in the center that could have been used as a primitive galvanic battery, also there are theories that the Egyptians used electric lights somehow due to the lack of soot found in tombs from fires candles or lamps.
These are only theories and have no evidence to support them.
Answer
The Ancient Egyptians did not have electricity. They used oil lamps for light.
There is no soot found in tombs because people did not live in tombs! A tomb was basically their version of a grave. Nobody lives in a grave!
Recorded use for medicine goes as far back as ancient civilisations such as the ones in Egypt. However, these were largely limited to herbs and plants, where synthetic drugs were not available.
Although, electricity was not explicitly discovered, it was known that iodestone posessed magnetic properties, and when amber and jet were rubbed together, it attracted things (static electricity). In 1600 English scientist William Gilbert made a careful study of electricity and magnetism and coined the term electricus which further evolved in to electric and electricity. In June 1752 , Benjamin Franklin conducted first experiment in which he attached a metal key to the bottom of a dampened kite string and flown the kite in a storm-threatened sky. The ancient greeks knew of static electricity. Electricity as we know it was discovered and studied by various scientists in the 1700s.
Electricity production is the main use for coal around the world. Saving electricity means less coal will need to be mined, shipped and burned.
Safety precautions are neccessary. Incorrect use of electricity can cause electric shock and fire. Both are life threatening and a real risk.
An electric device does not "use up" electricity, but rather energy. And strictly speaking, it doesn't "use up" energy, but transforms it from one form to another. It is common to say that energy is used up when it is transformed to less concentrated forms--when it is degraded. Electrical energy ultimately becomes heat energy. In this sense it is used up. ------ I have a washing machine - I think it's a typical appliance - it uses electricity and water. But it does not "use up" any electricity or water - there is always more. Same for all of our other appliances. The clothes washer (above), dryer (gas and electricity), dish washer (water and electricity), microwave (only electricity). Popcorn maker (only electricity), toaster (only electricity), refrigerator (only electricity). Really, what these appliances "use up" is counter or floor space, especially the big ones.
