The concept of environmentally friendly or eco friendly technology has a specific purpose where the main factor of its application is to preserve the environment. Especially in the digital era, which increasingly supports the rapid advancement of existing technologies, from agriculture, large industry, to household-scale industries.
The method of using environmentally friendly technology in everyday life arises because environmental conditions are getting worse due to selfish human activities in using and exploiting nature to meet their needs.
Quoting from the website of the Ministry of Environment and Forestry (Kemenlhk), the application of environmentally friendly technology is technology in the manufacture and application of the use of raw materials that are more environmentally friendly.
In the process of its use, various types of environmentally friendly technologies must meet special requirements and regulations. In terms of using resources, be it energy, raw materials, water, air, and chemicals more efficiently.
Applications and Examples of Environmentally Friendly Technologies in Energy and Industry
In its application, environmentally friendly technologies are now being applied in various fields, including industry, environment, transportation, and other energy fields. Here are some examples of the application of environmentally friendly technology in various resources for daily needs.
Biogas is a type of alternative fuel which is currently widely used as fuel to meet household needs. As reported by the Kompas.com website citing news from the Ministry of Education and Culture, biogas is obtained from the fermentation process of anaerobic bacteria organic matter (a type of bacteria that can live without oxygen).
These anaerobic bacteria is able to convert organic substances into methane gas and other types of gases such as carbon dioxide, hydrogen and hydrogen sulfide up to 75 percent. An example of biogas that is close to our daily lives is the use of gas for cooking.
Biofuel is the result of alternative energy supply technology using natural resources and can be renewed. The process of forming biofuels comes from organic materials such as plants.
Currently, there are two types of biofuels that can be used, namely in the form of biodiesel and ethanol. Ethanol is a type of alcohol that can be made from the fermentation process of carbohydrates. Meanwhile, biodiesel is a natural fuel obtained from vegetable fats.
3. Electric Car
Electric cars are the result of the application of environmentally friendly technology that minimizes the use of other fuels that can run out and damage nature. As the name implies, with this electric car, users can move a motorbike or car with electric energy as the driving force.
There are three types of electric car vehicles that have been developed and started to be used, namely HEV (Hybrid Electric Vehicle) which is a car that is driven from electricity, PHEV (Plug - in Hybrid) which is driven from a combination of electric motors and gasoline engines.
For more, a BEV (Battery Electric Vehicle) that can move using a battery source without a gasoline engine and can be recharged from an external power source. This type of electric car uses a combustion engine or ICE where electric power is stored in a battery pack.
One of the automotive brands that actively plays a role in environmental conservation is Hyundai. With the issuance of an electric car, the Hyundai Ioniq 5, users can still use electric cars while preserving the environment.
4. Solar Panels
Just how it’s called, solar cells are the result of a concept that converts sunlight energy into electricity through a man-made panel. When sunlight is absorbed by the solar panel, the light will produce an emission of electrons in the panel components.
Then, the electrons will be connected through a system to produce electric water. That electrical energy is flowed and can be stored in a battery and can be used at certain times of need, such as when the lights go out, cloudy or at night.
The use of solar panels certainly has various advantages, including being able to produce large amounts of energy, easy to install and move, and can be developed. However, this system of using solar panels also has a drawback, which is that it requires electricity storage.
Windmills are often heard and used as a source of energy. One of the countries that intensively uses windmills is the Netherlands. This windmill is an environmentally friendly energy source that is capable of producing electrical energy for various purposes and other fuel needs.
6. Electricity Generating Floor
Another technology that is proven to be environmentally friendly is the production of electricity-generating floors. One of these environmentally friendly stations was initiated by the Japanese state and has been running since 2008. In the area of this station, ceramic plates are affixed that are able to convert pressure into electric voltage.
With the use of this electricity-producing ceramic plate, all station visitors who step on this plate will generate electricity that can be used as an energy source. The more people passing by, the more electricity sources are saved.
Main Functions and Effects of Using Eco-Friendly Technology
The main function in using environmentally friendly technology is to facilitate and fulfill daily human needs. In addition, this environmentally friendly technology also functions to convert useless items into useful products for humans. The final effect of using this environmentally friendly technology is the preservation of nature from damage.
