"In its most recent forecast, the International Energy Agency said growth in demand for all forms of energy will grow 37 per cent by 2040, with oil demand rising by 15 per cent. Meeting that demand will require companies to invest, and the IEA cautioned against complacency in the current oversupply situation, pegging the amount that needs to be invested for future demand at $900 billion per year between now and 2030. The current environment is unlikely to encourage that activity.
Without that level of investment, the world risks an oil price spike, which is usually a one-way ticket to economic recession."
