Coal National Geographic Society
Coal is an important part of the world energy budget. It is relatively inexpensive to lo e and extract and can be found all over the world. Unlike many renewable resources such as solar or wind coal production is not dependent on the weather. It is a baseload fuel meaning it can be produced 24 hours a day 7 days a week 365 days a year.

What is coal? World Coal Association
Coal formation. All living plants store solar energy through a process known as photosynthesis. When plants die this energy is usually released as the plants decay. Under conditions favourable to coal formation the decaying process is interrupted preventing the release of the stored solar energy. The energy is locked into the coal.
