Crude oil at below $30 per barrel has a negative impact on the profitability and investments in renewable energies, Total's Chief Executive Officer Patrick Pouyanne, told a forum in Davos in Thursday.
Oil prices have fallen to multi-years lows in due to a persistent global supply surplus.
"Today at $30 a barrel, I'm sorry," Pouyanne said.
"I'm a big investor in solar and I was advocating that we have 20 countries where we could make solar profitable. It is not true today. At $30 a barrel, there is not a single one," Pouyanne said.
