INTRODUCTION: Electricity is one of the most important blessings that science has given to mankind. It has also become a part of every person’s life and one cannot think of a world without electricity. We utilize electricity in our day to day life, in enormous ways. It is used for lighting, fans, electronic gadgets and domestic appliances like using electric heaters, A/C, refrigerator and many other appliances. All these provide comfort in life. In factories, large machines are running because of electricity. Essential items like food, cloth, paper and many other things are the product of the factories who runs on electricity. Modern means of transportation and communication have been revolutionised by electricity. Electric trains and battery cars are quick means of transportation. Electricity also provides means of entertainment like radio, television and cinema, cell phones which are the most common and popular forms of entertainment are the result of electricity. Modern equipment like computers and robots have also been developed because of electricity. Electricity plays a pivotal role in the fields of medicines and surgery too. The use of electricity is increasing day by day. As, the demand and the consumption of the electricity is increasing we must explore option for the generation of the electricity. Now in a modern world we cannot rely on sources as coal and oil. If we keep on relying on these sources we will not only run out of these natural sources but also, we
One of the most important discoveries made in science was the invention of electricity. Can you imagine going through a day without the use of electricity? The discovery of electricity had changed how this planet functions .Electricity was first discovered around 600 B.C by the ancient Greece by rubbing amber and fur to create static electricity. A lot of people contributed to the discover of electricity including William Gilbert, Benjamin Franklin, and many more. Benjamin Franklin conducted an experiment to show that lighting was electricity. He experimented with a kite, key, and a storm in which he proved that lightening are tiny electric sparks. Electricity is used in our daily lives, led to new discoveries in science, made easier for
Energy is an important part of life producing the power of movement, heat, and production of electricity in many different ways. Therefore, choosing the correct source of energy is important for the environment and humans. Renewable energy that produces electricity never runs out, causing a lower environmental impact. Solar, Biomass, Wind, Geothermal, and Hydropower energy should be used globally to produce electricity. On the other hand, producing electricity from nonrenewable energy sources can be very harmful to humans and the environment. Humans can easily be dependent on it, which may not be the best option when it comes to finance, efficiency, sustainability and more. Approximately 52% of the US electricity comes from polluting sources like natural gas, oil, nuclear, and hydropower that have a lot of disadvantages effecting the environment in a negative way.
As the global population increases exponentially, having passed six billion in 1999, the world population is expected to be 8.9 billion by the year 2050. The worlds energy consumption will increase by an estimated 54 percent by 2025. Energy demand in the industrialized world is projected to grow 1.2 percent per year. Energy is a critical component of sustained economic growth and improved standards of living. One of the major requirements for sustaining human progress is an adequate source of energy. As the world’s technological enhancements and standards of living improve, so too does their appetite for electricity.
Fossil fuels and other power generates are slowly changing the world. Alternative power sources are slowly becoming more popular in everyday life while the technology progresses. Using these power sources that don’t pollute the atmosphere could be the change in the world that completely changes the way the world uses energy. Engineers and technicians have been producing these alternative ways for years and years. A few, but not limited to consist of: Solar panels, Wind turbines, Wave tech and much more.
This article explained how electricity was generated in the early 1900s. Burning coal in the city centers produced electricity and also helped to heat buildings. Only people near from the city were able to use electricity because there was not way to transmit the electricity to rural areas. After a long time coal plants started to grew and people were facing difficulties because the coal plants occupied space and they also produced pollution to the city. People decided to move coal plants to the outside of the city in that way people would not be affected, they started to use transmission wires to carry electricity. Even though they did not have the same efficacy to obtain electricity they were finding a way to improve it. At the beginning of 1970 technology began to improve, so many mass-produce engines were produce and they can be located in the middle of the population, also decentralized plants were used to recycle the wasted heat. After all these benefits of the new technology, industry decided to make some changes. Electric monopolies started to charge people for the use of electricity. Later on, congress tried to open competition in 1978 and some independent power companies started to develop one site generation. This article was focused in a research on how to build new power generation providing technology, capital costs and fuel prices. After all of this significant and dramatic changes in electricity, United States was facing problems because the power industry
Relevance Statement: Electricity is the heart of our current civilization. Without electricity we would regress into a feudal like stage which will slow down our evolution as a society
Nowadays, coal is still one of the greatest used energy to generate power in so many countries. Using coal in electricity generation is 93% in South African, 87% in Poland, 79% in China, 78% in Australia, 45% in USA, 41% in Germany, 58% in Israel etc. (Coal & Electricity) From the data above, even the developed countries use coal to generate power as the main source. In many developed countries, energy generation is still based on coal as a long-term source. In recent years, although there is an increasing number of equipment using gas and wind to generate the power, it is still lower than the proportion of coal-fired power generation. The reason why most countries choose coal as a main source to generate electricity, is that there are many advantages in using coal to generate electricity. First of all, coal is the
Energy Story, Hands-On Science with Squishy Circuits, and Conducting Solutions all have one important similarity: they all explain how electricity works!
From the time when man invented fire, he has put his faith in one energy source or another. Energy plays a significant factor in our lives, providing luxury, swelling productivity and letting us to live the way we want too. Our lives are exactly surrounded by energy, but we do not habitually stop to think about why those energy sources are significant. Energy is the most discussed subject and has become a basic requirement for the societies. It is an important factor on to which economies depend and prevail. Independence in energy leads to prosperity and economic progress in the country. The significance of energy generation cannot be unrecognized due to its crucial share in the industrial practice and growth of the
Obviously without electricity, you wouldn't be able to enjoy your daily explorations of the Day! What a horrible thought! But don't worry. Electricity does exist and it allows us to enjoy life in so many ways. Since electricity is a natural force that exists in our world, it didn't have to be invented. It did, however, have to be discovered and understood. Most people give credit to Benjamin Franklin for discovering electricity. Benjamin Franklin had one of the greatest scientific minds of his time. He was interested in many areas of science, made many discoveries, and invented many things, including bifocal glasses. In the mid-1700s, he became interested in electricity. Up until that time, scientists had mainly known about and experimented with static
