Energy Supply, Delivery, and Demand

The Nation’s economic security is increasingly dependent on an affordable and reliable supply of energy. Every sector of the economy depends on energy, from manufacturing to agriculture, banking, healthcare, telecommunications, and transportation.2 Increasingly, climate change and extreme weather events are affecting the energy system (including all components related to the production, conversion, delivery, and use of energy), threatening more frequent and longer-lasting power outages and fuel shortages.3 Such events can have cascading impacts on other critical sectors43,44 and potentially affect the Nation’s economic and national security (see Ch. 17: Complex Systems). At the same time, the energy sector is undergoing substantial policy-, market-, and technology-driven changes.2,31 Natural gas and renewable resources are moving to the forefront as energy sources and energy efficiency efforts continue to expand, forcing changes to the design and operation of the Nation’s gas infrastructure and electrical grid. Beyond these changes, deliberate actions are being taken to enhance energy security, reliability, and resilience with respect to the effects of climate change through integrated planning, innovative energy technologies, and public–private partnerships;1,2,31,45 however, much work remains to establish a climate-ready energy system that addresses present and future risks.
