Electricity has huge and growing uses as a form of energy; this is due to its flexibility and reliability.

Electricity has several resources that are used to produce it namely, the fossil fuels, water, solar, wind, hydrogen and many others.

Invention of electricity does not have a specific inventor but instead has a chain of inventors.

However, Benjamin franklin is credited for discovering electricity in the 18 century.

So science has much improved the means of transport and conveyance.

In pre-science times, books could be purchased only by the rich people, as on account of their being written by hand, they were very costly. After tungsten replaced carbon in its filament, the lightbulb was considered “perfected.” As of 2013 they are being phased out worldwide in favor of compact fluorescent bulbs, which are four times as efficient. Bartlet, who each had a milestone on the road (pun intended) to successful automobile and bicycle tires. The bottleneck in the chain of production was composing the printing plates. Not yet in wide use as transportation in 1913, but “To [Samuel] Langley and to the Wright brothers must be awarded the chief honors in the attainment of mechanical flight.” In 2013 the annoying aspects of commercial airline flying make transportation by horse and buggy seem a viable alternative.

The “aeroplane” came in second, although it was considered important because of its potential, not because there were so many airplanes in the sky. By adding tungsten to steel, “tools so made were able to cut at such a speed that they became almost red hot without losing either their temper or their cutting edge” The increase in the efficiency of cutting machines was “nothing short of revolutionary.” 4. The Linotype and the Monotype dispensed with that bottleneck.In history, many people have come up with several inventions in the aim of making the lives of human beings better and comfortable.As life continues, different inventions are changing at the same rate as the changing world.A century from now they might be curious as to what all the fuss was about. C., and was thus well informed on the progress of inventions. The electric furnace (1889) It was “the only means for commercially producing Carborundum (the hardest of all manufactured substances).” The electric furnace also converted aluminum “from a merely precious to very useful metal” (by reducing it’s price 98 percent), and was “radically transforming the steel industry.” 2. The answers from 1913 thus provide a snapshot of the perceptions of the time. The steam turbine, invented by Charles Parsons in 1884 and commercially introduced over the next 10 years. Many inventors worked toward the goal of a “self-propelled” vehicle in the 19th century. For “the Realization of an age-long dream” he gave the laurels of success to the Wright brothers, but apart from its military use reserved judgment on the utility of the invention: “It presents the least commercial utility of all the inventions considered.” 6. Systems for transmitting information between people have been around for centuries, perhaps millennia. A single machine is capable of doing more work than a thousand men.An electric crane can easily lift a load of a thousand kilograms.
