SOME INFORMATION ABOUT THERMAL ENERGY

Heat (Thermal energy)

Thermal energy is what we call energy that comes from heat. For example, a cup of hot tea has thermal energy in the form of kinetic energy from its particles. When you pour some milk into your tea, some of this energy is transferred to the particles in cold milk. What happens next? The cup of tea is cooler because it lost thermal energy to the milk.

The atoms and molecules that make up a substance are in constant motion. This movement is what gives a material its temperature: the more the molecules are moving about, the higher the temperature. Thermal energy is simply the energy possessed by a substance due to the movement of its atoms or molecules. It is important not to confuse this with heat, which is energy that is transferred from one place to another. Thermal energy has long been exploited by humans for cooking, heating, power generation and industry.

Thermal energy facts.


- thermal energy is one of the oldest forms of energy that was harnessed by humans. It is widely believed that Archimedes' used this form of energy to burn invading Roman ships.
- thermal energy is one of the most affordable modes of energy. Is a renewable energy.
-It has been estimated that if used properly, businesses can save around 40% of their electricity bills by switching to solar thermal energy.
- thermal energy can be used in conjunction with other sources of energy, and can be used to lower the costs associated with fossil-fuels.
-It doesn't cause any pollution, and doesn't contribute to the greenhouse effect.
-According to research, one megawatt hour (MWh) of electricity produced due to thermal energy prevents the emission of a ton of carbon dioxide in the atmosphere.
