History of Electricity - The oldest civilization known to understand electricity was the ancient Greeks because of the electric fish in the Nile River. In the 1600’s William Gilbert an English Physician studied electricity and magnetism; studies were continued by other researchers such as Robert Boyle and Benjamin Franklin. Then by the 1800’s scientist Allesandro Volta had identified a way to harness electricity in a battery format and he had also discovered the chemical reactions that electricity could produce. Volta also invented the first device with a steady current known as the electric battery, and he also created the first transmission of electricity by linking positively-charged and negatively-charged connec...   [tags: electricity, science]

Sources of Electricity - In order to explain what is electricity, first we must start off with talking about an atom. An atom is made up of protons neutrons, and electrons. The protons (positive charge) and neutrons (neutral charge) form the nucleus, while the electrons (negative charge) orbit around the nucleus. The atom is considered balanced if the protons and electrons are the same. But, if the atom loses or gains an electron it becomes an unbalanced atom. Losing electrons makes the atom have a positive charge because there are more positively charged protons than electrons....   [tags: Energy, Electrons, Protons]

The Use of Wind Power in Denmark and Japan - ... In contrast, Japan struggles to use wind power energy. In 2012, Japan had 1,855 wind turbines and produced 2,556.8 MW (Komatsubara, 2012). Even though the number of wind turbines increased, and the amount of energy which is created by wind turbines improved, the amount of energy was only 0.40% of total energy demand in Japan (“Renewables 2013 Japan Status Report,” 2013). According to Main(e) International Consulting LLC (Bossler, 2012), many Japanese companies were likely to be reluctant to spend much money on wind power like foreign companies such as Vestas+NEG-Micon in Denmark and GE Wind Energy+TACKE in Germany....   [tags: electricity, james blyth, wind engines]
