The movement of atoms within a substance generates thermal energy. Basically, this is the form of energy that comes as a result of heat. As atoms in an object move faster, temperature rises. As a result, thermal energy i... More »

Much of the world's energy supply is concentrated in the hands of a very small number of nations. Human energy consumption is increasing at a rate that some consider alarming, as of 2015. More »

In physics, energy is a system's capacity to perform work, which is force acting on an object. Energy has many forms, including kinetic or mechanical energy, potential energy, light energy and heat energy. The basic rule... More »

The formula for calculating thermal energy is Q = mcΔT, where "Q" represents the thermal energy, "m" indicates the substance's mass, "c" denotes the specific heat and "ΔT" signifies the temperature difference. Thermal en... More »

Heat differs from thermal energy in that heat is the transfer of thermal energy from one location, object or substance to another. Thus, heat is a process that happens to thermal energy and is meaningless without it. The... More »

Bioenergy is renewable energy made from renewable harvested material. Biomass is used to supply heat, generate power and fuel transportation. Bioenergy accounts for more than 10 percent of the world's energy consumption,... More »
