thermal energyInternal energy of a system in thermodynamic equilibrium (see thermodynamics) by virtue of its temperature. A hot body has more thermal energy than a similar cold body, but a large tub of cold water may have more thermal energy than a cup of boiling water. Thermal energy can be transferred from one body, usually hotter, to a second body, usually colder, in three ways: conduction (see thermal conduction), convection, and radiation.

It is important that the thermal load profile closely follow the electric load profile so as to make maximum use of the waste heat energy from the cogenerator. For instance, Sussman explains mow heat energy from the sun is converted into the moving energy of the wind, how it evaporates water to power the water cycle, and how it's trapped on Earth by the greenhouse effect. Some of the heat energy radiates back toward Earth, and some radiates higher into the atmosphere, eventually escaping into space. |
