The U.S. indictment of Gautam Adani has thrown a spotlight onto the rolling risks of India’s solar industry. Last week, prosecutors in New York charged the billionaire and several others of securities and wire fraud by agreeing to bribe government officials to secure solar power contracts for the Adani Group’s $19 billion renewable energy unit.

U.S. prosecutors allege that Gautam Adani, the second most-wealthy Indian man, personally met with Indian government officials to further their “bribery scheme.”
