Fuel from bogs is a type of renewable energy source that is derived from PEAT, which is a type of organic matter found in wetlands. PEAT is formed over thousands of years from the accumulation of partially decayed plant material and is harvested for use as fuel. It is an important source of energy in many parts of the world, particularly in areas with limited access to other forms of energy. PEAT is also used in horticulture and gardening as a soil conditioner.
