Possibly 3,000 to 4,000 years ago. Wow. In funeral pyres. In the second century (100 AD) coal is mentioned as a heating source in England. See links.
Not sure if this will answer your question, but I'll give it a shot. It's less about the fact that is is coal and more about the fact that coal gives off heat. When coal was first being used as a heat source, it was cheaper than wood and there was a lot of it. So really the origin of the energy is in the heat that the coal generates when on fire and less about the coal itself.
The first power plants were installed by Edison in the 1880's, and were powered by coal, so that's the answer
Coal began to replace the wood in the 1800s because the wood became scarce in some places. in the 1900s coal replace wood as a chief energy source because of its many used such as the fuel for steam engines which powered the many railroad engines popular during the period, and fuel for the steam turbines used in the production for electricity.
how long has oil been used for
Coal was first used as a fuel in ancient China around 3,000 BC, where it was burned for heating and cooking. Its use spread to other parts of the world, including Europe, where it became increasingly important during the Industrial Revolution in the 18th and 19th centuries. By then, coal was a primary energy source, powering steam engines and factories, significantly impacting industrial growth.
Coal is used by communities by BBQ
The energy in coal is stored as potential energy during its formation over millions of years. This potential energy is released as heat when the coal is burned, which is then used to generate electricity through steam turbines.
The main types of energy in coal are chemical energy, which is released when coal is burned, and potential energy stored within the coal itself. When coal is burned, the chemical energy is converted into thermal energy, which can be used for generating electricity or heating.
Coal, wind, hydroelectricity, and solar. Coal is most used.
Coal has potential chemical energy which is released as heat when it is burned.
Coal is burned and the energy is created from the heat of the coal burning and is collected and used and it gives off more energy than other things like peanuts for example. And coal is used for electricity and also heating homes in some places.
"Create as much energy" is poorly defined. The amount of energy produced from solar energy will depend on the surface area used for solar panels, the weather, the efficiency of the panels, and for how long it is used. Similarly, the amount of energy produced by a coal power plant would depend on its size, its efficiency (which of course may also vary), and for how long it is used. Please think about what exactly you want to compare.
Its coal and hydrogen
No, burning coal does not involve mechanical energy. When coal is burned, it undergoes a chemical reaction to produce heat, which can then be used to generate mechanical energy through processes like steam turbine systems.
Coal was first used 1,000 to 5,000 years ago!
The energy in a lump of coal is primarily stored chemical energy that is released when the coal is burned. This energy is typically used for electricity generation or heating purposes. The amount of energy in coal can vary depending on factors such as its type and quality.
When coal is burned, chemical energy stored in the coal is converted into heat energy. This heat energy is then used to produce steam, which drives turbines to generate electricity.
