Coal was first used 1,000 to 5,000 years ago!

Historical evidence indicates that coal was first used 3,000 to 4,000 years ago during the Bronze Age. in this time the people of southeastern Wales used coal for funeral pyres to burn their dead.
In terms of total energy consumption in the United States, coal accounts for approximately 32 percent. The vast majority of coal is used to generate electricity.
It is burned in coal-fired power plants to supply energy.

In coal burning plants, the first energy transformation that occurs is the combustion of coal to produce heat energy. This heat energy is then used to generate steam, which drives a turbine connected to a generator to produce electricity.
In a coal burning power plant, the first energy transformation that occurs is the chemical energy stored in the coal being converted into thermal energy through combustion. This thermal energy is then used to produce steam, which drives turbines to generate electricity.

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.
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.
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.
