Who invented light bulbs ?

Throughout the next hundred years, many inventors and scientists tried to find a way to use electrical power to make light. In 1879, the American inventor Thomas Edison was finally able to produce a reliable, long-lasting electric light-bulb in his laboratory.
By the end of the 1880s, small electrical stations based on Edison's designs were in a number of cities, but each station was able to power only a few city blocks.
By 1930, the majority of people living in larger towns and cities had electricity, but only 10 percent of Americans who lived on farms and in rural areas had electric power.
In 1935, the Rural Electric Administration was created to bring electricity to rural areas.By 1939, the percentage of rural homes with electricity had risen to 25%.

Today, nearly everyone is fortunate enough to have electric power at home, school, and at work. In order to maintain this constant and reliable resource, it is important that we use it wisely every day.
