There are various sources that can produce heat energy. The source of heat energy and their uses are quite diverse. The presence of heat energy has an important role in various daily activities.
Of course, with this heat energy, it will make everything that humans do in their daily lives easier. Therefore, humans will certainly depend on the heat energy on this earth.
In this explanation, several examples of existing heat energy will be given. Apart from that, the uses of this heat energy will also be given. The following include:
1. Sun
The sun, as the primary source of heat energy in the solar system, produces a flow of energy that is vital for the survival of life on Earth every second.
Even though it is not visible to the human eye, its real impact is felt through various life processes.
This heat energy is a force that is locked in the atomic structure of an object, such as the heart that circulates blood throughout the body.
This analogy describes the essential activity of heat energy that supports the existence of the object.
The role of this energy is very important in maintaining the survival of living things.
Whether in everyday activities such as dropping objects, or larger phenomena such as explosions, everything requires energy as a trigger.
2. Air
Thermal energy produced by air is an important aspect of energy resources. The use of heat energy from air has become widespread, used in various sectors such as industry and household needs.
The use of air as a source of heat energy is generally not direct.
As one example, heat energy and its uses are usually used to produce other types of energy first, such as electrical or mechanical energy, before finally being converted into heat energy.
3. Geothermal
The Earth has the potential to provide heat energy, although the amount is not as much as that received from the sun. This phenomenon is known as geothermal energy.
Geothermal energy sources are found in hot springs and rocks hidden in the ground.
Apart from that, geothermal heat can also be accessed in liquid form in magma found in deeper layers of the earth’s crust.
4. Electricity
Electrical energy has high flexibility in its use. For example, electrical energy can be converted into heat energy, as happens in irons, water heaters and rice cookers.
On the other hand, electricity generation can be carried out by utilizing available resources, which are in accordance with its geographical characteristics.
In areas with many rivers, electricity can be generated through the use of water turbines.
Meanwhile, in areas that have strong winds, wind turbines can be used to produce electrical energy with the same efficiency.
5. Fuel
Electrical energy has extraordinary flexibility, it can be converted into other forms of energy such as heat.
For example, heat energy and its use in activities such as ironing clothes, heating water, or cooking rice uses electrical energy to produce the required heat.
The electricity generation process varies depending on the natural resources available in a region.
In areas that have many rivers with curved topography, electrical energy can be generated through the use of water turbines.
Meanwhile, in areas that have strong winds, the use of wind turbines is an effective way to produce the same amount of electrical energy.
6. Friction of Two Objects
The heat energy produced from the friction of two objects is also called thermal kinetic energy.
This occurs when two objects rub against each other, converting the energy of motion into heat energy.
Its uses are wide-ranging, such as in generating electricity through friction generators, heating materials in industrial processes, and driving machines in various technological applications.
Another use is when we are cold, rub our palms together to keep them warm.
7. Fire
Thermal energy produced from fire is a form of heat energy that arises from burning fuel such as wood, coal, natural gas or oil.
This energy has a variety of uses, from cooking food, heating rooms, generating electricity through thermal power plants, to being used in industrial processes such as metal smelting and glass making.
That is a description related to examples of heat energy and its uses. These various examples will certainly have quite an influence on human life.
