Chemical energy

Chemical energy is energy stored in the bonds of chemical compounds (atoms and molecules). Chemical energy is released in a chemical reaction, often in the form of heat. For example, we use chemical energy in fuels like wood, and coal by burning them.

Mechanical Energy

Mechanical energy is the energy a substance or system has because of its motion. For example, machines use mechanical energy to do work.

Electrical Energy

Electrical energy is the energy carried by moving electrons in an electric conductor. It is one of the most common and useful forms of energy. Example – Lightening. Other forms of energy are also converted to electrical energy. For example, power plants convert chemical energy stored in fuels like coal into electricity through various changes in its form.

Thermal energy

Thermal energy is the energy a substance or system has related to its temperature, i.e., the energy of moving or vibrating molecules. For example, we use solar radiation to cook food.
