Top 10 Best Cleantech Companies in India 2023
Cleantech, short for “clean technology,” refers to products, services, or processes that use renewable materials and energy, emit fewer emissions, and have a minimal impact on the environment. Cleantech companies are therefore those that are involved in developing and implementing such technologies.
Cleantech encompasses a diverse range of innovative products and services in various sectors such as:
Energy generation: Companies in this sector develop and operate renewable energy sources like wind, solar, hydroelectric, tidal, and geothermal power. Examples include companies like First Solar and Vestas.
Energy storage: These companies focus on technologies that store energy for later use, like advanced batteries and fuel cells. An example of this would be Tesla with its Powerwall product.
Energy efficiency: These companies make energy use more efficient. This can involve technologies to improve building efficiency, smart grid technologies, or more efficient industrial processes. Examples include companies like Johnson Controls and Cree Inc.
Waste management: Companies that use technology to manage waste more effectively, either by reducing waste, converting waste into energy, or recycling, fall under this category. An example would be Covanta Holding Corporation.
Water and wastewater: This sector includes companies that are involved in treating water and wastewater, monitoring water quality, and improving water efficiency. Companies such as Danaher and Xylem Inc. operate in this space.
Sustainable transportation: Companies that provide technologies for more sustainable transportation options, such as electric cars, electric bikes, and car-sharing services. Tesla and BYD are known for their electric vehicles.
Agriculture: Companies that make farming and food production more sustainable through precision farming, bio-based materials, and other techniques. Companies such as AeroFarms and Impossible Foods would fall into this category.
Why Cleantech Companies are important
Cleantech companies are critical for several reasons:
Environmental Impact: First and foremost, cleantech companies are designed to be environmentally friendly, using renewable resources, producing less waste, and emitting fewer pollutants. This helps to combat environmental degradation and climate change.
Sustainability: Cleantech companies are a key component of creating a sustainable economy, one that can continue to thrive without depleting our planet’s resources. Traditional industries often rely heavily on non-renewable resources, whereas cleantech industries seek to use renewable and sustainable resources.
Innovation: Cleantech companies are at the forefront of technological innovation. They are developing the next generation of technologies that will power our world, from energy generation and storage to sustainable agriculture and transportation.
Economic Growth: Cleantech is a rapidly growing sector that is creating jobs and stimulating economic growth. Investments in cleantech also create a ripple effect across the economy, stimulating growth in other sectors as well.
Energy Security: By developing domestic sources of clean energy, cleantech companies reduce a country’s reliance on foreign sources of energy, thereby increasing energy security.
Health Benefits: By reducing pollution, cleantech companies improve air and water quality, which leads to health benefits. For example, reducing air pollution can decrease the incidence of respiratory diseases.
Addressing Climate Change: Finally, and perhaps most importantly, cleantech companies are a critical part of the global response to climate change. By developing and implementing technologies that reduce greenhouse gas emissions, these companies are helping to mitigate the effects of climate change.
History of Cleantech Companies in India
India’s journey towards clean technology has its roots in the late 20th century, but it has grown significantly in the 21st century due to various factors like environmental concerns, government policies, and international collaborations.
Early Stage: The early cleantech movement in India started in the late 1980s and early 1990s with a focus on renewable energy, mainly wind and small hydro projects. Suzlon Energy, established in 1995, became a significant player in the wind energy sector.
Shift Towards Solar Energy: The Indian government announced the Jawaharlal Nehru National Solar Mission in 2010 under the National Action Plan on Climate Change, with the aim of making India a global leader in solar energy. The target was to deploy 20GW of grid-connected solar power by 2022, but this was later increased to 100 GW in 2015 considering the potential of solar power in India.
Electric Vehicles (EVs): In recent years, India has made substantial strides in promoting electric mobility. The government launched the National Electric Mobility Mission Plan (NEMMP) 2020 and the Faster Adoption and Manufacturing of (Hybrid &) Electric Vehicles (FAME) schemes, which aim to promote the manufacturing of electric and hybrid vehicles and to ensure sustainable growth of the same.
Start-Up Boom: Since the mid-2010s, India has seen a surge in cleantech start-ups thanks to supportive government policies, increasing environmental awareness among the population, and an influx of domestic and foreign investment. Companies like ReNew Power (renewable energy), Ather Energy (electric scooters), and ZunRoof (solar solutions for homes) have emerged as significant players.
International Collaboration: International collaboration and foreign investment have also played a major role in the cleantech movement in India. India, along with France, launched the International Solar Alliance (ISA) in 2015 at the Paris COP21 climate summit. The ISA aims to promote solar energy in 121 solar resource-rich countries.
Continued Progress: As of 2023, India continues to be a significant player in the cleantech space. The country is not only focusing on renewable energy but also on other areas like waste management, water treatment, green buildings, and sustainable agriculture.
Benefits of Cleantech Companies
Cleantech companies provide numerous benefits, both economically and environmentally. They help to address some of the most pressing issues of our time, including climate change, environmental degradation, and energy scarcity. Here are some of the primary benefits of cleantech companies:
Reduced Environmental Impact: Cleantech companies aim to deliver products and services that have a smaller environmental footprint compared to traditional technologies. This includes lower greenhouse gas emissions, reduced water usage, less waste, and lower levels of pollution.
Energy Efficiency: Many cleantech companies focus on improving energy efficiency, whether it’s in buildings, transportation, industrial processes, or energy generation and distribution. Greater energy efficiency not only reduces environmental impact but can also result in substantial cost savings.
Job Creation: The cleantech sector is a significant source of job creation. These jobs range from high-tech positions in research and development to manufacturing, installation, and maintenance roles.
Economic Growth: Cleantech industries can stimulate economic growth. In addition to creating jobs, they can attract investment and spur the development of new industries.
Energy Security: By increasing the supply of renewable energy, cleantech companies can reduce reliance on fossil fuels, which are often imported from other countries. This can increase energy security and stability.
Health and Safety: Cleantech solutions often result in improved air and water quality, which can have substantial health benefits. For example, reducing air pollution can decrease the incidence of respiratory diseases.
Innovation: Cleantech companies are often at the cutting edge of technology and innovation. They contribute to the development of new technologies and solutions that can have far-reaching impacts across various sectors of the economy.
Sustainability: Perhaps most importantly, cleantech companies contribute to the transition towards a more sustainable economy. They play a critical role in ensuring that our economic development does not come at the expense of our planet’s health and future generations.
