French oil giant Total said on Monday that it would pay $2.5 billion (€2bn) for a 20 per cent stake in India’s Adani Green Energy Ltd (AGEL), a major solar energy producer, as it diversifies away from fossil fuels into renewables. Along with the 20 per cent direct stake comes a 50 per cent holding in a portfolio of solar energy assets operated by AGEL, part of the Adani group, Total said in a statement.
