The term electricity (English: electricity ) comes from the word electron which in Greek means amber. Electricity can be defined as electrons flowing in a conductor (conductor) in a circuit.
Electricity = the flow or movement of electrons

ELECTRICAL HISTORY
The discovery of amber stone by an ancient Greek mathematician, Thales of Miletus (625-547 BC), became the initial discovery of electricity. At that time, Thales took a yellow amber stone formed from a lump of hardened resin. Then he rubbed the stone with wool cloth. Unexpectedly, the feathers around him were attracted to and attached to the amber stone. Thales put forward the phenomenon as a symptom of electricity.
Remember yes, electricity is meant here is one object that can attract other objects.
After years since Thales’s observation, in 1600 William Gilbert (1544-1603), English physician and physicist, published ” De Magnete, Magneticisque Corporibus, et de Magno Magnete Tellure ” in Latin. In it contains a full report about his research in the field of magnetism and electrical attraction. In this work, Gilbert argues that electricity and magnetism are not the same thing.
However, in 1820, Hans Christian Oersted (1777-1851), a Danish physicist and chemist, discovered the connection between electricity and magnetism. Through experiments, Oersted managed to prove that the conductor with electric current can produce a magnetic field.
And vice versa, electricity can be generated from magnets. This has been proven by a British physicist and chemist, Michael Faraday (1791-1867). In 1831, Faraday conducted an experiment about the interaction between magnets and the coil of conductive wire. A magnet that was pushed back and forth between a coil of electric currentless wire turns out to be able to induce an electric current to flow in the coil of wire.
The event is known as electromagnetic induction, a principle behind electricity generation whose main component is the generator. For this discovery, Faraday earned the nickname “Father of Electricity”.
WHY MUST SAVE ELECTRICITY?
The electricity we currently use comes from power plants. Power plant is a device that can produce electrical energy from a particular source, one of which is fossil fuels such as coal, oil, and gas.
Quoting from wwf.or.id , more than one third of the world’s electricity is generated from coal, including Indonesia. Deputy Minister of Energy and Mineral Resources (ESDM), Arcandra Tahar, stated that coal will still be the main energy source for electricity generation in Indonesia until 2050. This is because coal is still a very cheap energy compared to new energy sources and renewable (EBT).
Despite its low price, coal-fired steam power plants (PLTU) —and other fossil-fueled power plants — produce carbon dioxide (CO2) gas which is released into the atmosphere as combustion. This means that the electricity sector also contributes to greenhouse gases (CO2) as a cause of global warming.
By saving electricity and using it wisely, we can reduce CO2 emissions from this sector.
In addition, a change in policy to switch to more environmentally friendly power plants will help reduce the percentage of CO2 emissions from this sector.
Recently, the latest global electricity data revealed a surprising finding in 2019 when CO2 emissions from this sector fell by 2%.
A study published by the ROUTERS website (London) on Monday, March 8, 2020, released that the cause of the reduction in CO2 emissions was due to the reduced use of coal energy as a power plant in the United States and Europe. Coal power plant in the US fell because of the transition to gas. Whereas in the European Union it happened because of the transition from coal to the wind and the sun.
HOW ABOUT INDONESIA?
Power plants in Indonesia are still dominated by coal-fired power plants, which is 48% of the total domestic generating capacity. Then followed by gas and steam power plants (22%), diesel (11%), gas, and machinery and gas (8%). While renewable energy power plants, such as hydropower, PLTS, PLTMH, PLTBio, and PLTP hold a figure of around 12%.
A small percentage of renewable energy is due to the high cost of generating energy. The government still cannot switch from cheap energy to relatively more expensive EBT.
Well, let’s support the Government to immediately switch to more environmentally friendly energy. By saving electricity consumption, we will reduce the increasing electricity demand. Now, from here we can reduce CO2 emissions from the electricity sector. It could be that with electricity demand that is not so surging, the Government will immediately switch to renewable energy.
THINK – ACT —SAVE
By thinking and acting wisely, we can help protect the Earth from global warming.
That’s all, hopefully the article MAINTAINING THE EARTH WITH ELECTRICAL SAVE is useful for you guys, thank you.
