Green Technology: Everything You Need To know

The global call for sustainability has never been more urgent. From climate change to the depletion of resources, the world has become acutely aware of natural crises that pose a threat to the very functioning of the ecosystem. As humankind grapples with the devastating impacts, the importance of green technology has escalated to the forefront of discussion.

What exactly is green technology? Here’s the breakdown—Green technology, often referred to as clean technology or environmental technology is a broad term that uses the advancements of science and innovation to reduce the negative human impact on the environment by conserving natural resources and mitigating resource degradation thereby maintaining ecological equilibrium.

The core purpose aims to create products and services that preserve natural resources, promote sustainable development, and renewable energy, and reduce emissions, and waste of resources. Covering a wide range of sectors like transportation, energy, waste management, agriculture, and even artificial intelligence, it is an integral component of human life.

This article will analyze the fundamental principles, applications, benefits, and challenges of green technology with an in-depth understanding of how it can foster a healthy habitat. 

Why green technology?

Green technology, abbreviated as green tech focuses on utilizing renewable energy, improving its efficiency, reducing pollution, and reusable or sustainable materials in production. Central to its philosophy is the thought that technological advancements should not be at the cost of ecological destruction rather, technology should be utilized to restore and revive ecological harmony. The exploitation is evidenced by alarming statistics.

For instance, deforestation accounts for more than 10% of greenhouse gas emissions. Reports also state that around 18 million acres of forest are lost each year due to industrial and agricultural expansions. According to the World Bank, around 3 billion people are frequently exposed to air pollution with an estimated premature death of 7 million annually. Technological advancements in the fishing sector resulted in the drastic depletion of stocks due to overfishing. Additionally, there is a staggering rise in e-waste with an estimate of nearly 53.6 million metric tons generated yearly.

The combustion of fossil fuels and natural gas for energy not only depletes the sources but also accounts for carbon emissions, which cause air pollution and warming. In light of carbon emissions and their catastrophic impacts, green technology is the need of the hour. Global carbon levels are reaching unusual heights– causing climate change, extreme weather conditions, rising sea levels, melting of polar ice sheets, and increased ecological disruption. This emphasizes the need for sustainable alternatives.

Green technology opens a viable future for innovations that harness renewable energy to preserve nature. The shift to cleaner energy sources like wind, solar, and hydropower can notably reduce carbon footprint and open windows for economic growth and occupation in this sector. It also promises to reduce waste and safeguard the pristine conditions for future generations. For the investors out there, investing in green tech is not a mere choice, it is a necessity with abundant benefits, government incentives, and long-term profits.

• Lifecycle assessment: From extraction of raw materials to production, manufacturing, use, reuse, and disposal, green tech covers the entirety. Minimizes environmental impacts at all stages.

Where can we use green technology?

As green tech is versatile, it can be incorporated across various sectors to improve sustainability and environmental impact. Switching to green technology allows individuals, communities, and businesses to include innovative technological solutions. Below are some key areas where green tech can be applied.

Renewable Energy

A major cornerstone of green technology involves utilizing energy from sources that are naturally refilled without causing severe damage to the natural environment. 

• Solar Energy: Sunlight captured by solar panels is converted into electricity using photovoltaic cells. It is cost-effective and ideal for producing energy for domestic and commercial purposes, especially in the tropic to sub-tropic areas.
• Wind Energy: Effective in coastal areas with high wind speed. The wind turbines convert kinetic energy to electricity. 
• Hydropower: The energy of flowing water is used to produce energy. Hydropower is one of the most used and oldest forms of renewable energy.

Transportation

A rapid increase in population led to a surge in transportation, a major contributor to greenhouse gas emissions. 

• Electric vehicles(EV): The adoption of electric bikes, cars, and buses reduces the reliance on fossil fuels. EVs produce zero emissions, as they run on electricity. 
• Hydrogen fuel cells: They only emit water vapor, making it a clean alternative to traditional engines.
• Public Transit: Incorporating electric or hybrid transportation options and micro-mobility reduces traffic congestion and pollution.

Agriculture

Even though agriculture sounds nature-friendly, it causes environmental harm in terms of deforestation, soil runoff, and usage of harsh chemicals. Green tech offers solutions to make agriculture more sustainable.

• precision farming: Uses technology to minimize waste and environmental impacts. Using GPS, drones, data analytics, and weather forecasts to optimize the use of fertilizers, water, and pesticides and increase the crop yield.
• Vertical farming: indoor farming practices using hydroponics or aeroponics reduce the need for large agricultural areas. It uses less water and fertilizers and even reduces transportation as the farm can be located closer to customers. 
• Organic Farming: avoids the use of chemicals and synthetic fertilizers reducing the harmful impacts by reducing chemical alteration in the soil and runoff into water bodies. 

Waste Management

Traditional waste disposal methods like landfills, incineration, and open dumping contribute to pollution and emissions. Technological advances have reduced this to a certain extent
