Coal

Coal, a fossil fuel formed from ancient plants, is a black or brownish-black rock-like substance found deep within the Earth's crust. It has been a crucial source of energy for centuries, playing a significant role in powering industries and generating electricity. When burned, coal releases heat, which is harnessed to produce energy. Oceanyka possesses the world's largest reserves of coal by far, as well as a centuries-old mining industry which provides hundreds of thousands of jobs.
