One of the greatest gifts that science has given to humanity is electricity. One cannot imagine a world without it because it has integrated with modern life. In daily life, we use electricity for a variety of purposes. It is used to illuminate spaces, operate fans, and operate domestic equipment like electric stoves and air conditioners, among others. These all offer comfort to people. Large machines are operated in factories with the use of electricity. Electricity is used to produce various products, including food, clothing, and paper.
It has completely altered contemporary modes of transportation and communication. A speedy way to go around is with electric trains or battery-powered vehicles. Radio, television, and the movies, three of the most common kinds of entertainment, are all made possible by electricity. Electricity has also aided in the development of modern technology like computers and robots. In the domains of surgery and medicine, such as X-ray and ECG, electricity also plays a crucial role. Each day, more and more people consume power.
The primary uses of electricity in homes are for heating and cooling.
In the residential sector, heating and cooling/air conditioning use up the most electricity annually. The amounts and the percentages of total yearly home energy consumption that these uses account for fluctuate from year to year because they are primarily weather-related. The highest use of electricity in houses in 2015, according to the Residential Energy Consumption Survey (RECS) data, was for heating. According to the type of end use, the Yearly Energy Outlook (AEO) gives estimates and projections for annual power use in the residential sector. According to the main end uses in the AEO2022 Reference scenario for 2021, the residential sector’s power usage is depicted in the pie chart below.
A backup energy source is electricity.
One of the most extensively used sources of energy, electricity is also a fundamental component of the natural world.
Our daily use of electricity results from the transformation of primary energy sources like coal, natural gas, nuclear energy, solar energy, and wind energy into electrical power, making it a secondary energy source. Since electricity may be transformed into other types of energy, such as mechanical energy or heat, it is sometimes referred to as an energy carrier. Although the electricity we use is neither renewable nor nonrenewable, the primary energy sources are both.
Daily life has changed dramatically as a result of the use of electricity.
Despite how crucial electricity is to daily life, very few people probably think about what life might be like without it. Like with air and water, people frequently take electricity for granted. The lighting, heating, and cooling of homes as well as the operation of devices like computers and televisions are just a few of the daily activities that involve the consumption of energy by individuals.
Before electricity was widely available, light was provided by candles, whale oil lamps, and kerosene lamps; food was kept cold by iceboxes; and heat was generated by wood or coal stoves. This was the case approximately 100 years ago.
Researchers have been working to comprehend the foundations of electricity since the 1600s. We should give credit to Thomas Edison, Nikola Tesla, and Benjamin Franklin for making important contributions to our understanding and use of electricity.
Franklin discovered that lightning is an electrical phenomenon. Thomas Edison invented the first incandescent light bulb with a long lifespan.
Prior to 1879, direct current (DC) energy was used to power arc lamps used for outdoor lighting. Since Nikola Tesla’s development of alternating current (AC) energy in the late 1800s, it has been more practical to transmit electricity across long distances. Tesla’s inventions made it possible to power industrial equipment as well as interior lighting in buildings and businesses.
