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 »

Solar energy has been used by humans for 2,700 years. Originally, glass lenses were used to make fire with the sun's rays. According to the U.S. Energy Information Administration, the first recorded use of a solar therma... 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 »
