Global oil demand is likely to keep rising for at least another 15 years before Asia’s fast growing economies catch up to the shift from hydrocarbons to electric power, a leading consultancy said on Monday.

“At some point in the next 20 years, it’s likely we’re going to see oil demand peak. Our own view at Wood Mackenzie, is around 2035, 2036,” Wood Mackenzie chairman Simon Flowers said in an interview with CNN Business.
