Unveiling his infrastructure conglomerate’s green vision, billionaire Gautam Adani on Tuesday said his group will invest USD 20 billion over the next 10 years in renewable energy generation and component manufacturing and will produce the world’s cheapest green electron. The port-to-energy conglomerate plans to triple its renewable power generation capacity over the next four years, foray into green hydrogen production, power all data centres with renewable energy, turn its ports into net carbon zero by 2025, and plans to spend over 75 per cent of capital expenditure until 2025 in green technologies, he said.
