Introduction
The urgency for sustainable practices has never been more pressing in this century than at any other time in history. Otherwise referred to as clean technology, green technology is the application of science and technology to come up with green, environmentally friendly, and sustainable products and services. This blog addresses recent innovations within the preview of green technology from a global perspective and draws special attention to India and other countries.
Solar Energy Innovations
The solar energy industry has been at the very front when talking about green technology; however, the years of 2021 through 2024 were dramatic in terms of progress viewed in this area. In 2023, MIT researchers developed a new type of solar cell that manages to be more efficient and less expensive to make at the same time. In addition, perovskite materials in the solar cells are said to be fabricated at a lower temperature compared to traditional silicon cells. This has the potential to reduce the cost of solar power tremendously and thus enable more people around the world to afford it.
The Indian government has been endeavouring to make the use of solar energy a habit since 2019 through various policy initiatives, including the "PM-KUSUM" initiative. It targets the installation of about 30.8 GW solar power capacity by 2024, largely by providing solar pumps to farmers and encouraging the setting up of solar power plants on barren lands.
Electric Vehicles and Sustainable Mobility
Other high-growth, related areas of green technology innovation are in the area of electric vehicles. The entire world is doing its best towards EVs; countries like Norway are leading the charge. In 2021, Norway posted over 54% of all new cars sold that were electric. This does not appear to be a strictly developed-world phenomenon—India is on the move in this regard.
In 2022, one of India's biggest automobile makers, Tata Motors, pledged US$2 billion to EV technology. The commitment would further be interpreted to mean a product line of relatively cheap electric cars in a bid to target the Indian market. Not to be left behind, the Indian government rolled out a scheme called 'Faster Adoption and Manufacturing of Hybrid and Electric Vehicles' (FAME) to push the cause of electric mobility. By 2024, 30 percent of India's vehicles would run on electricity and thereby significantly reduce the carbon footprint of the nation.
Sustainable Agriculture
Agriculture forms one of the most important industries in any economy and hence requires sustainable agricultural practices to preserve food security and protection of the environment. One such innovation in this regard is precision agriculture, which involves using technology-based techniques to help maximize crop yields while reducing waste.
In 2023, an Israeli startup developed a drone-based system that began monitoring crop health using artificial intelligence in real-time. This system detects problems such as pest and nutrient deficiency issues early, hence giving farmers the chance to take action on time and prevent major damage. Similar technologies are being put into practice in India too. Cropin's use of AI and big data is meant to bring insights that will enable better crop management by farmers.
Waste Management and Recycling
Proper waste management definitely belongs to the key factors in the name of sustainability, and innovations make it easier to recycle and re-use different streams of waste nowadays. In 2022, scientists from Cambridge University prepared a new kind of plastic that is fully biodegradable. This plastic can decompose without residues harmful to the environment and, thus, gives an answer to the global plastic waste crisis.
It has not lagged behind in innovation related to solid waste management either. In 2023, the Government of India brought out Swachh Bharat Mission 2.0 for solid waste management, laying emphasis on encouraging recycling. It envisaged the set-up of waste-to-energy plants under this scheme that would convert the organic waste into biogas, a renewable source of energy.
Green Buildings and Sustainable Architecture
Other major contributors to carbon emissions come from the construction industry, which green buildings are now helping to cut. A green building is a structure that achieves energy efficiency by making use of sustainable materials and technologies that reduce their breaking and harmful impacts on the environment.
One example is the Al Bahar Towers in Abu Dhabi, innovatively designed in a way that its façade opens and closes as the sun moves to minimize the usage of air conditioners. In India, through the Indian Green Building Council, efforts have been put into the area of sustainable building practices. More than 7,000 projects for green buildings were registered in 2024.
Conclusion
Green technologies and innovations for sustainability will fundamentally change the way of life, work, and interaction with the environment in the future. Innovations in the fields of solar energy, electric vehicles, sustainable agriculture, waste management, and green buildings all show ways toward a far more sustainable future. Such innovations, therefore, will enable us to work towards reducing our ecological footprint and ensuring a healthy planet for future generations.
That small difference is going to make a gigantic impact. To do so, we believe in and campaign for green technologies that will be paramount in having a liveable and prosperous future.
