The resurgence in oil and gas production from the United States, deep declines in the cost of renewables and growing electrification are changing the face of the global energy system and upending traditional ways of meeting energy demand, according to the World Energy Outlook 2017. A cleaner and more diversified energy mix in China is another major driver of this transformation.
Over the next 25 years, the world’s growing energy needs are met first by renewables and natural gas, as fast-declining costs turn solar power into the cheapest source of new electricity generation. Global energy demand is 30% higher by 2040 – but still half as much as it would have been without efficiency improvements. The boom years for coal are over — in the absence of large-scale carbon capture, utilization and storage — and rising oil demand slows down but is not reversed before 2040 even as electric-car sales rise steeply.
