More frequent and graver extreme events continue to remind us of the perils of climate change, but systematic consideration of these extremes in energy systems studies and full accounting of their impacts remains a challenge.

Climate change entails an intensification of extreme weather events that can potentially trigger socioeconomic and energy system disruptions. As we approach 1 °C of global warming we should start learning from historical extremes and explicitly incorporate such events in integrated climate–economy and energy systems models.

Non-market effects, such as strategic decisions by the Organization of the Petroleum Exporting Countries, energy legislation and speculative bubbles, move crude oil prices away from the level implied by supply and demand for extended periods.
