In the modern era, the use of technology exists in almost all business fields, from agriculture, micro industry to large scale industry. However, the use of inappropriate technology actually has a negative impact on the health of the environment and also the surrounding community, therefore green technology or environmentally friendly technology is needed to prevent these negative impacts from occurring.
This environmentally friendly technology is a technological breakthrough specifically designed to minimize negative impacts on the natural environment. This can include technology used to reduce air, water and land pollution, and can manage resources efficiently and minimize waste. Therefore, it is very important to implement environmentally friendly technology in order to promote the sustainability of our nature so that its sustainability is maintained and also so that we can avoid negative impacts due to natural damage in the future. The following are several examples of environmentally friendly technology.
1. Renewable Energy
Renewable Energy is an energy source that can be renewed continuously, such as sunlight, wind, water, geothermal heat and biomass. Renewable energy does not produce greenhouse gas emissions such as carbon dioxide or methane, so it is a more environmentally friendly and safe choice to use compared to non-renewable energy sources, for example oil, coal and natural gas. Renewable energy can also reduce dependency on limited energy sources, such as petroleum and coal, which can run out if used continuously and can become increasingly expensive over time. Some examples of renewable energy.
Wind energy: Wind energy can be taken from windmills which consist of a rotor that can rotate by the wind. Wind energy can be used to produce electricity. Water energy: This water energy can be taken from water sources that flow in rivers with fast currents or from waves in the sea. Water energy can be used to produce electricity through a water turbine.
Geothermal energy: Geothermal energy can be extracted from the heat contained beneath the earth's surface. Geothermal energy can be used to produce electricity.
Biomass energy: Biomass energy is energy produced from biodegradable organic materials, such as wood, garbage and also agricultural waste. Biomass energy can be used to convert biomass into electrical energy.
Energy recovery: energy recovery is the process of converting energy that can no longer be used into energy that can be reused. Here are some examples of energy recovery:
Thermal energy recovery: Thermal energy recovery is the process of taking waste heat from machines or industrial processes and reusing it to heat space or water.
Electrical energy recovery: Electrical energy recovery is the process of taking wasted electrical energy from electronic equipment and reusing it.
Mechanical energy recovery: Mechanical energy recovery is the process of taking wasted energy from the movement or change in position of an object and reusing it. For example, mechanical energy recovery can be carried out in the braking system which converts the car's kinetic energy into heat, which can then be reused to heat the car's brakes.
Shock energy recovery: Shock energy recovery is the process of taking wasted energy from changes in pressure or temperature and reusing it. For example, shock energy recovery can be carried out in an air compressor system that converts wasted air pressure energy into electrical energy.
2. Environmentally Friendly Technology
Environmentally friendly technology in transportation is technology used in transportation systems that functions to reduce greenhouse gas emissions and air pollution. The following are several examples of environmentally friendly technology in transportation, including the following.
Electric vehicles: Electric vehicles are vehicles that use batteries as their main energy source. Electric vehicles do not produce greenhouse gas emissions or carbon dioxide so they are more environmentally friendly compared to vehicles that use fossil fuels such as petrol or diesel.
Hybrid vehicles: Hybrid vehicles are vehicles that use a combination of electrical energy sources and fossil fuels as their main source of propulsion energy. It is believed that hybrid vehicles can reduce greenhouse gas emissions and air pollution because they use more efficient energy sources.
Electric buses: Electric buses are buses that use batteries as their main energy source. Electric buses do not produce greenhouse gas emissions, so they are more environmentally friendly compared to buses that use fossil fuels such as petrol or diesel.
