Previously chief of Shell, Voser said he believes the future of transportation over the next 40 to 60 years will be dominated by a mixture of self-driving vehicles, combustion engines and electric cars.

That should be an opportunity, not a worry, for energy players, he said.

While major companies like Shell still remain active in gas, “business models will evolve,” Voser said. Big energy firms are comfortable with technological developments, “and I think they will transform themselves as well.”

There are also enough incentives by regulators to increase corporate levels of energy efficiency, he added.
