Introducing to green technology

     The term technology usually refers to the application of various techniques, skills, methods and processes for any and all practical purposes or to achieve certain objectives such as scientific investigation or research. A technology that is environmentally friendly in its production, supply chain or usage is referred to as Green Technology or Green Tech for short. Green tech is an umbrella term that continuously develops products, system or equipments which are less taxing to the natural environment and its resources which limit and diminishes the negative effect of human exercises. The world we live in has a limited amount of natural resources which are referred as Non-Renewable resources or the resources which can be depleted during the course of time. Human activities caused many to already perish from the face of the Earth. According to the estimate Global Footprint Network in 2018, humans are consuming natural resources 1.7% faster than the Earth can replenish. Therefore, the need of the hour is that we as a society should invest in Green Tech as they are:

1) Less taxing to the natural environment thus reduces the resources depletion.

2) Emission of greenhouse gases (GHG) (CO2, CH4, N2O) is considerably less or zero.

3) Usage of renewable resources (wind, solar) is encouraged.

 

 

 

 

 

 

 

 

 

 

 

Advantages of Green Tech and Hurdles to Cross

  • ●  Helps in recycling and managing waste materials.

    ●  It is environmentally friendly as a result emit zero or less harmful materials in the environment

    ●  Maintaining the Green Tech is very cost efficient.

    ●  Green Tech helps conserve energy

    ●  It is also helping in rejuvenating the health of our ecosystem.

 

 

 

 

Sectors Using Green Tech

a) Energy Sector: Right now, this is the fact that the majority of the world’s energy
is being produced by burning fossil fuels. Green tech can be used to build alternative,
more environmentally sustainable fuel sources than fossil fuels. Usually fossil fuels
produce waste as a by-product of their production. Instead of fossil fuels; solar, wind,
and hydroelectric dams can be used, since they are environmentally cleaner and do not
produce any harmful by-products.

b) Transportation Sector: One of the biggest contributors of global GHG emission
are conventional fuel based vehicles. Therefore, many companies are incorporating
Green Tech in transportation infrastructure and vehicles in the form of electric vehicles
and compressed natural gas (CNG) buses.

c) Waste Management Sector: Green Tech is also being used in waste management
sector for transporting, storing and recycling of wastes.

d) WaterFiltration:Aroundtheworld,greentechisbeingwidelyusedforwaterpurification.
Countries around the world where water supply is limited, green tech may be used for
purifying polluted water or extracting salt from seawater to improve the supply of safe
drinking water.

e) Air Purification: Green tech is also being used to clean the polluted air by decreasing
the carbon emissions and gases released from the industrial sectors.

 

Why Is Green Technology Necessary

Green technology 's primary aim is to control global warming and reduce the greenhouse effect. The principal concept is to develop innovative inventions that do not affect the natural resources. It will result in less damage to humans, animals and our planet's overall health. Now it is obvious that our world is beginning to suffocate from all the waste that we produce. But if there's a will, then there's a way to make this problem much smaller. The successful use of green technologies will make a major contribution towards reducing emissions. This is why many developed and some developing countries are now transitioning towards this form of technology to help protect them from harmful impacts on the climate.

The Case of Electric Vehicles

Electric vehicles (Evs) are proving to be a more viable option over conventional vehicles. Electric cars and trucks are proving to be even cleaner than the most efficient traditional vehicles, in terms of air pollution and greenhouse gas emissions. Charging EVs exclusively from renewable electricity can be proven to be completely emission free. While it is true that no GHG emissions come directly from EVs but they run on electricity which is still predominantly derived from fossil fuels in most parts of the world. Energy is also used to manufacture the vehicle-and the battery in particular. There are many studies being published showing that the carbon footprint of an EV is the same as conventional vehicles but the problem with that data is it includes the carbon emissions of power plants that produce the electricity using fossil fuels. That same argument, however, can be applied for conventional cars, taking into account the amount of carbon emissions produced during the drilling and refining of crude oil.
