Man’s intelligence is immeasurable. This is a fact that is tested and proven by time. And with the help of Science and Technology, the improvements of things are never-ending. There’s a continuous development and discovery of a wide variety of stuff. Scientists keep on experimenting and discovering different things which can help man’s life become simpler and better.
Let’s take electricity as an example. Way back in history, our ancestors don’t have electricity. They only relay on what the nature can provide them. The sun is their source of light during the day and the moon during the night. The wind is their natural source of air unlike at the present time, where there are machines such as electric fan and the like that can produce air.
Electricity is the term used when there is an encompassing variety of phenomena resulting from the presence and flow of electric charge. It is an extremely flexible form of energy with a countless number of uses. Electricity is used in telecommunications, refrigeration and also in electric vehicles.
Each country has different companies that provide electricity. These companies have different matrix and rates on how they charge their customers in their electricity usage.
