Why Cleantech Is The Future?


Clean technology is the technology of the future. The demand for clean and sustainable practices across industries is vital. Embracing change for a better tomorrow requires more attention than ever before.

India, as it makes its way into the market, is slowly and steadily adapting to this shift and has recently seen a tremendous increase in the number of green-tech start-ups.

Several Indian clean technology startups are working on developing amazing solutions to help construct a sustainable energy future. This, in turn, is creating a buzz across the entire ecosystem among investors and entrepreneurs looking to invest in this field.

Indeed, India today offers a very profitable commercial sector for the Cleantech industry, with countless enterprises and FDI inflows being sucked into the field.

This article discusses the current challenges affecting India's Cleantech sector, as well as the opportunities for this industry's future development, as well as its possible direction.

The Term 'Greentech':

Given the imminent consequences of global warming and increased fossil fuel combustion, as several nations declare a climate emergency and take moves toward feasible options for preserving the climate and biodiversity, clean (and green) technology has risen to the top of the public agenda.

This area, often known as 'Cleantech,' is attracting a lot of attention from researchers, academics, technologists, industry specialists, and other stakeholders.

Due to the rapid depletion of natural resources, increasing population, and urbanization, the globe is rapidly shifting towards renewable energy. Sustainable products and solutions are in high demand as a result of this circumstance.

How Does It Work?

As we know or even if you don't know allow me to explain Clean technology also synonymous with "Greentech" is any technology that is used to reduce negative effects and helps in improving environmental sustainability.

Cleantech acts like an umbrella that covers investment, technology, and business sectors which include clean energy, environmental, and sustainable or green, products and services.

The size of the Indian clean-tech market was nailed down to be at more than $25 billion in 2017, and by the end of 2030, India plans to meet 40% of its total energy needs using renewable resources, compared to 22% currently.

So how does cleantech works earlier cleantech was used to refer to a wide range of technologies and practices, such as solar and wind energy. 

Production to process improvements that can increase efficiencies in supply chains and production lines helps cleantech to remain popular in the financial, VC, and business communities.

The term cleantech has its origins in the venture capital (VC) investment community, which began using the term in the late 1990s and early 2000s.

The devastation caused by unsustainable growth, the depletion of fossil fuels, and the increase of global warming have pushed us to the brink of disaster. Moving towards a more sustainable way of life is our only option, and as a result, individuals, corporations, and governments alike have begun to adopt a cleaner and greener approach.

This plan is referred to as Cleantech, which encompasses a wide range of technologies and companies such as recycling, renewable energies (solar, hydropower, wind energy, biofuels), green construction, electric vehicles, lighting, and so on.

India is also working hard to adopt clean technology solutions. Though the business is still in its infancy, we are confident that it will help our country thrive in ways we could never have imagined, leading us to a green and clean country.

The concept of cleantech is still new to Indians it's still an emerging idea but it's quickly developing in India and it's being noticed by the govt as well. The Government of India is additionally boosting this area by proposing different approaches and rules.

If India's wind, solar, biomass and hydro resources are appropriately channeled, this region could change the country's electricity generation. Clean advancements can eliminate the issue of natural contamination brought about by non-sustainable wellsprings of energy.

Additionally, it can likewise address the dire need for energy for all. These improvements ultimately led to an expansion of the cleantech market.
