After unveiling its plans to harness wind energy, ONGC, the country's leading crude and gas producer, now plans to foray into solar and geothermal energy.

The company is in talks with four companies, including a US-based firm, for setting up a photovoltaic (PV) cells unit.

The oil and gas major is also exploring geothermal energy for which it is in talks with Iceland government. All these projects will be carried out under its ONGC Energy Centre housed at Rajiv Gandhi Urja Bhavan, New Delhi.
