“You can't not like everything,” Tinker said, noting renewables like wind or solar do not produce enough power to meet the world's needs.
Tinker said world leaders must have some difficult discussions about how to balance its energy mix, a situation made tougher by the differing resources available around the world.
“I think that's a fascinating global conversation,” he said.
Tinker predicts fossil fuels will provide less of the world's energy by 2080, dropping from 70 percent in 1980 to 60 percent in the future, but consumption will rise because of growing global demand.
He said the U.S. shale boom likely will spread to other parts of the globe, making it even more difficult to replace fossil fuels from the world's energy mix.
He said energy efficiency efforts can ease the transition, making him optimistic the change can be made.
“I think we can do it,” he said.
