Benjamin Franklin was the founder of electricity. The term 'electricity' is derived from a term used by William Gilbert in 1600 to describe static electricity. The discovery that lightning is electrical was made by Benjamin Franklin in 1759.

There are many reasons why electricity is important but one of the main reasons is, electricity is obtained in different ways and is used as a power source of the machines and gadgets that makes the activities in our daily lives easier and faster.

William Gilbert is credited as one of the originators of the term "electricity" and also remembered largely for his book De Magnete (1600). He is regarded by some as the father of electrical engineering or electricity and magnetism. But, Michale Faraday was also one one the great contributors in field of electricity.

William Gilbert (also Gilberd) was born on 24 May 1544 into a prosperous family in Colchester, Essex. He was educated at Cambridge University, where he received a BA, MA and MD, after which he became a senior fellow. He practised as a doctor in London for many years and in 1600 became president of the Royal College of Physicians. He served as physician to Elizabeth I in the last few years of her reign.'De Magnete' was published in 1600 and was quickly accepted as the standard work on electrical and magnetic phenomena throughout Europe. In it, Gilbert distinguished between magnetism and static (known as the amber effect). He also compared the magnet's polarity to the polarity of the Earth, and developed an entire magnetic philosophy on this analogy.Gilbert's findings suggested that magnetism was the soul of the Earth, and that a perfectly spherical lodestone, when aligned with the Earth's poles, would spin on its axis, just as the Earth spins on its axis over a period of 24 hours. Gilbert was in fact debunking the traditional cosmologists' belief that the Earth was fixed at the centre of the universe, and he provided food for thought for Galileo, who eventually came up with the proposition that the Earth revolves around the Sun.Gilbert died on 30 November 1602, probably of the plague.

Franklin as Printer and Publisher. He returned to Philadelphia in 1726, and two years later opened a printing shop. The business became highly successful producing a range of materials, including government pamphlets, books and currency. In 1729, Franklin became the owner and publisher of a colonial newspaper, the Pennsylvania Gazette, which proved popular–and to which he contributed much of the content, often using pseudonyms. Franklin achieved fame and further financial success with “Poor Richard’s Almanack,” which he published every year from 1733 to 1758. The almanac became known for its witty sayings, which often had to do with the importance of diligence and frugality,” such as “Early to bed and early to rise, makes a man healthy, wealthy and wise.”In 1730, Franklin began living with Deborah Read (c. 1705-74), the daughter of his former Philadelphia landlady, as his common-law wife. Read’s first husband had abandoned her; however, due to bigamy laws, she and Franklin could not have an official wedding ceremony. Franklin and Read had a son, Francis (1732-36), who died of smallpox at age 4, and a daughter, Sarah (1743-1808). Franklin had another son, William (c. 1730-1813), who was born out of wedlock. William Franklin served as the last colonial governor of New Jersey, from 1763 to 1776, and remained loyal to the British during the American Revolution. He died in exile in England.

Electricity for powering our homes, schools and businesses is made in power stations. Spinning turbines turn large magnets within wire coils - this causes electrons to move, which results in electricity. Turbine generators turn, spinning giant magnets within copper coils to create energy.

Italian physicist Alessandro Volta discovered that particular chemical reactions could produce electricity, and in 1800 he constructed the voltaic pile (an early electric battery) that produced a steady electric current, and so he was the first person to create a steady flow of electrical charge.

Alessandro Volta, in full Conte Alessandro Giuseppe Antonio Anastasio Volta, (born February 18, 1745, Como, Lombardy [Italy]—died March 5, 1827, Como), Italian physicist whose invention of the electric battery provided the first source of continuous current.Volta became professor of physics at the Royal School of Como in 1774. In 1775 his interest in electricity led him to improve the electrophorus, a device used to generate static electricity. He discovered and isolated methane gas in 1776. Three years later he was appointed to the chair of physics at the University of Pavia.In 1791 Volta’s friend Luigi Galvani announced that the contact of two different metals with the muscle of a frog resulted in the generation of an electric current. Galvani interpreted that as a new form of electricity found in living tissue, which he called “animal electricity.” Volta felt that the frog merely conducted a current that flowed between the two metals, which he called “metallic electricity.” He began experimenting in 1792 with metals alone. (He would detect the weak flow of electricity between disks of different metals by placing them on his tongue.) Volta found that animal tissue was not needed to produce a current. That provoked much controversy between the animal-electricity adherents and the metallic-electricity advocates, but, with his announcement of the first electric battery in 1800, victory was assured for Volta.Known as the voltaic pile or the voltaic column, Volta’s battery consisted of alternating disks of zinc and silver (or copper and pewter) separated by paper or cloth soaked either in salt water or sodium hydroxide. A simple and reliable source of electric current that did not need to be recharged like the Leyden jar, his invention quickly led to a new wave of electrical experiments. Within six weeks of Volta’s announcement, English scientists William Nicholson and Anthony Carlisle used a voltaic pile to decompose water into hydrogen and oxygen, thus discovering electrolysis (how an electric current leads to a chemical reaction) and creating the field of electrochemistry.

Chemical energy. This is stored, or “potential,” energy. Releasing chemical energy from carbon-based fuels generally requires combustion like the burning of coal, oil, natural gas, or a biomass such as wood.
Thermal energy. Typical sources of thermal energy include heat from underground hot springs, combustion of fossil fuels and biomass (as noted above) or industrial processes.
Kinetic energy. Kinetic energy is movement, which occurs when water moves with tides or flows downstream, or when air moves wind turbines in the wind.
Nuclear energy. This is the energy stored in the bonds inside of atoms and molecules. When nuclear energy is released, it can emit radioactivity and heat (thermal energy) as well.
Solar energy. Energy radiates from the sun and the light rays can be captured with photovoltaics and semiconductors. Mirrors can be used to concentrate the power. The sun’s heat is also a thermal source.

It has now become a part of our daily life and one cannot think of a world without electricity. Electricity is now an important part of homes & industries. Almost whole the devices at homes, businesses and industries are running because of electricity.

Thomas Alva Edison (February 11, 1847 to October 18, 1931) was an American inventor who is considered one of America's leading businessmen. Edison rose from humble beginnings to work as an inventor of major technology, including the first commercially viable incandescent light bulb. He is credited today for helping to build America's economy during the nation's vulnerable early years. Thomas Edison’s inventions included the telegraph, the universal stock ticker, the phonograph, the first commercially practical incandescent electric light bulb, alkaline storage batteries and the Kinetograph (a camera for motion pictures). Thomas Edison was the youngest of seven children of Samuel and Nancy Edison. His father was an exiled political activist from Canada, while his mother was an accomplished school teacher and a major influence in Thomas’ early life.

He invented an object that uses power but I don't think he invented power.
