How is the energy used in everyday life?
Explanation:
The process of converting one type of energy into another is known as energy conversion or energy transformation. Every minute of every day, energy is converted somewhere. There are many different types of energy, including thermal, electrical, nuclear, electromagnetic, mechanical, chemical, and sound energy.
Energy comes in a variety of shapes and forms. Below are some illustrations of typical energy conversions.
Scenario | Energy conversions involved |
Warming up by rubbing both hands together | Kinetic Energy to Thermal Energy |
An object falling quickly | Gravitational Potential Energy to Kinetic Energy |
Using a torch powered by batteries | In the battery: Chemical to Electrical Energy In the bulb: Electrical to Radiant Energy |
Regarding Geothermal Power Plant | Heat Energy to Electrical Energy |
In Hydroelectric Dams | Gravitational potential energy to Electric Energy |
In Electric Generator | Kinetic energy / Mechanical work to Electric Energy |
In Windmills | Wind Energy to Mechanical Energy or Electric Energy |
In OTEC | Heat Energy to Electric Energy or Mechanical Energy |
Using Microphone | Sound Energy to Electric Energy |
Photosynthesis in Plants | Solar Energy to Chemical Energy |
In Piezoelectrics | Strain to Electric Energy |
In Electric lamp | Electric Energy to Heat and Light Energy |
Burning of wood | Chemical energy to Heat and Light Energy |
In Fuel cells | Chemical Energy to Electric Energy |
In steam engine | The heat energy to Mechanical Energy |
In Electric heater | Electric Energy to Heat |
