2-Minute Revision
Clean Technology encompasses innovations that minimize environmental harm and maximize resource efficiency, crucial for India's sustainable development and climate goals. Constitutionally supported by Articles 48A and 51A(g), and legally by the Environment Protection Act, 1986, it forms the backbone of India's green transition.
Key technologies include solar, wind, and green hydrogen for energy, electric vehicles for transport, and waste-to-energy for waste management. Government initiatives like the National Solar Mission, PM-KUSUM, FAME India, and the National Green Hydrogen Mission are driving rapid adoption.
Internationally, platforms like the International Solar Alliance and frameworks under the Paris Agreement facilitate technology transfer and climate finance. While offering immense benefits in energy security, climate change mitigation, and economic growth, clean technology faces challenges such as high upfront costs, technology transfer barriers, critical mineral dependencies, and grid integration issues.
A holistic approach combining policy support, financial incentives, R&D, and international cooperation is essential for its widespread success.
5-Minute Revision
Clean Technology, a vital subset of Green Technology, focuses on processes and products that significantly reduce negative environmental impacts through enhanced energy efficiency, sustainable resource utilization, and pollution prevention.
Its importance for India stems from the need to achieve energy security, mitigate climate change, and foster sustainable economic growth. The constitutional mandate for environmental protection (Articles 48A, 51A(g)) and comprehensive legislation like the Environment Protection Act, 1986, provide a strong legal foundation.
India's clean technology landscape is diverse, featuring large-scale deployment of solar and wind energy, the burgeoning electric vehicle sector, and strategic investments in green hydrogen. Waste-to-energy solutions address the dual challenge of waste management and power generation, while carbon capture technologies aim to decarbonize heavy industries.
Government initiatives are pivotal: the National Solar Mission has propelled India to a global leadership position in solar, PM-KUSUM empowers farmers with solar energy, FAME India accelerates EV adoption, and the National Green Hydrogen Mission aims to establish India as a global hub.
International cooperation, exemplified by the International Solar Alliance and commitments under the Paris Agreement, is crucial for technology transfer and climate finance. However, significant challenges persist, including high capital expenditure, ensuring effective technology transfer, developing robust charging and grid infrastructure, managing the intermittency of renewables, and securing critical minerals for manufacturing.
Addressing these requires a multi-pronged strategy involving innovative green finance mechanisms, robust domestic R&D, strategic international partnerships, and streamlined regulatory frameworks. From a UPSC perspective, understanding these interconnections and the policy-implementation gap is key for comprehensive answers.
