Yes, in fact, the coal we burn for energy is mostly made of the element carbon. Sixty percent of lignite is carbon, while it makes up eighty percent of anthracite. This is how coal emits heat and why it creates carbon dioxide when burnt.
Yes, burning carbon for energy is what produces carbon dioxide, the greenhouse gas we’re having trouble with. In the carbon cycle, plants then absorb that carbon dioxide and can make it into materials like cellulose. When we burn wood we are releasing the energy stored in the carbon-based molecules and turning the carbn back to carbon dioxide.
