On average, coal has an energy content of about 24,000,000 joules per kilogram. This energy content can vary depending on the type and quality of the coal.
The energy content of coal can vary, but on average, one kilogram of coal contains around 24 megajoules (MJ) of energy.
The energy content of coal varies depending on its type and grade, but on average, coal contains about 24 megajoules (MJ) per kilogram. This means that 1 kilogram of coal can produce approximately 24,000 joules of energy when burned. Higher-grade coals, such as anthracite, can have energy contents exceeding 30 MJ/kg, while lower-grade coals may have less.

One ton of coal produces approximately 24 million joules of energy when burned.
It depends on the efficiency of the coal conversion process. If the process is 30% efficient, then 70 joules would be lost to the environment for every 100 joules of chemical energy stored in coal.
