Sources of thermal energy can serve as substances, energy potential which is sufficient for the subsequent transformation of their energy into other kinds of the purpose of the subsequent purposeful use. The energy potential of substances is a parameter which allows to estimate the fundamental possibility and expediency of their use as sources of energy, and is expressed in units of energy: joules (j) or kilowatt (thermal) - hours (kW(th)•h). All energy sources are divided into primary and secondary. The primary source of energy called matter, energy potential which is the result of natural processes and does not depend on human activity. The primary sources of energy include fossil fuel and fissile substances, heated to a high temperature water of the Earth (thermal water), Sun, wind, rivers, seas, oceans, etc. Secondary sources of energy are substances that have a certain energy potential and which are by-products of human activity; for example, the spent combustible organic matter, municipal waste, hot exhaust fluid industrial wastes (gas, water, steam) heated air emissions, agricultural wastes, etc.
