The correct answer is 2022.

The Energy Conservation (Amendment) Bill, 2022, was passed in India. This landmark legislation aims to significantly reduce India's carbon footprint and transition towards a cleaner energy future. A key aspect of the bill is the mandate to utilize non-fossil fuel-based energy sources, promoting renewable energy adoption at a national level. Furthermore, the bill establishes a domestic carbon market, a crucial mechanism for incentivizing emissions reduction and facilitating the trade of carbon credits. This market-based approach is expected to drive investments in clean technologies and sustainable practices. The act empowers the central government with regulatory powers to enforce and monitor compliance with these objectives, which includes the ability to levy penalties for non-compliance.

The bill's passage marks a pivotal moment in India's commitment to tackling climate change and achieving its ambitious renewable energy targets. It represents a significant shift towards a more sustainable and environmentally conscious energy landscape.
