India will introduce new rules to encourage companies to shift towards low-carbon energy sources, Raj Kumar Singh, Minister of State for Power, New and Renewable Energy said.

India's two richest men are vying to be at the forefront of Prime Minister Narendra Modi's ambition to ramp up green energy capacity in the world's second-most populous country more than four-fold to 450 gigawatts (GW) by 2030. They have mostly avoided operating in each other's space and the renewable energy push by Ambani's flagship Reliance Industries and the Adani group of companies will be the highest profile faceoff between them.

Global regulators published a blueprint on Wednesday to give a "sense of direction" to proliferating initiatives for tackling climate-related financial risks before they fragment markets. The roadmap attempts to align rules still in the planning stage between now and 2023 to avoid more divergences between various measures for the same activity.

State-owned power giant NTPC on Sunday said it has set a target to install 60 gigawatts (GW) of renewable energy (RE) capacity by 2032. NTPC has become India's first energy company to declare its energy compact goals as part of the UN High-level Dialogue on Energy (HLDE), according to a statement.
