But do you know when I was first discovered, many believe the electricity was first discovered by the ancient greeks more than two thousand, five hundred years ago. They produced electricity by rubbing fur against smooth stone. Next, do you know how fast electricity travels? The answer is the speed of light. That is about three hundred million meters per second. Another interesting fact is about electric cars. They are very popular now. But the idea is not new. British vendor Robert Anderson invented the first electric car around eighteen thirty two. However, this car was not very useful. IT wasn't possible to drive electric cause until the second half of the nineteen century. Finally, we are always trying our best to make good use of this energy. But according to a report, billions of pounds of electricity is wasted every single year in the U. K. And another report shows that in the U. S. A about thirty percent of the electricity used in offices each year is wasted. This just shows how important IT is to save the electricity in our daily lives. That's all for me today. I hope you enjoyed learning a bit more about electricity.
