Mukesh Ambani's Reliance Industries is pushing into the green energy sector with the Dhirubhai Ambani Green Energy Giga Complex in Jamnagar, Gujarat. Spanning over 5,000 acres, the complex will house five gigafactories for photovoltaic panels, energy storage, electrolysers, fuel cells, and power electronics. 

The company aims to be a leader in clean energy and has set a target of establishing 100 GW of solar energy capacity by 2030. 

The complex's sheer scale, reportedly four times that of Tesla's Gigafactory, underscores the company's ambition to create a fully integrated, global-scale clean energy ecosystem.
