Climate change impacts on future residential electricity consumption and energy burden: A case study in Phoenix, Arizona

Constantine (Costa) Samaras is the Director of the Carnegie Mellon University Scott Institute for Energy Innovation, the Trustee Professor of Civil and Environmental Engineering, and an Affiliated Faculty Member in the Department of Engineering and Public Policy. His research focuses on the pathways to clean, climate-safe, equitable, and secure energy and infrastructure systems. Costa analyzes how technologies and policies affect energy use and national security, resilience to climate change impacts, economic and equity outcomes, and life cycle environmental emissions and other externalities. He is a Founder and Director of both the Center for Engineering and Resilience for Climate Adaptation and the Power Sector Carbon Index. He is by courtesy, a faculty member in CMU's H. John Heinz III College of Information Systems and Public Policy. From 2021-2024, he served in the White House Office of Science and Technology Policy (OSTP) as the Principal Assistant Director for Energy, OSTP Chief Advisor for Energy Policy, and then OSTP Chief Advisor for the Clean Energy Transition, where he worked with the OSTP Director, Deputy Director for Industrial Innovation, and senior governmental leaders in coordinating Federal activities on U.S. energy policy, assessing energy technologies for meeting U.S. climate, resilience, equity, and security objectives, and aligning energy innovation systems to achieve U.S. climate commitments.

With more than two decades of experience in energy, transportation, and climate change, he has served on three National Academies Committees evaluating emerging energy technologies and earth systems research, served as the Chair of the ASCE Committee on Adaptation to a Changing Climate, and served on the Alternative Transportation Fuels and Technologies Committee the Energy Committee of the Transportation Research Board. He has published numerous studies examining electric and automated vehicles, renewable electricity, life cycle assessment, clean energy transitions and decarbonization policy, AI ethics, and climate resilience, in journals such as Nature, Proceedings of the National Academies of Sciences, Nature Climate Change, Environmental Research Letters, Climatic Change, and others. He was also a contributor to the 4th National Climate Assessment, and was one of the Lead Author contributors to the Global Energy Assessment.

Power Trip: The Story of Energy

artificial-intelligence-makes-energy-demand-more-complex-and-more-achievable

Artificial intelligence, a field known for its expanding uses across society, is also increasingly notorious for the massive amount of energy it needs to function.

Trustee Professor of Civil and Environmental Engineering

  In a 2024 paper, researchers from Carnegie Mellon University and machine learning development corporation Hugging Face found that generative AI systems could use as much as 33 times more energy to complete a task than task-specific software would.

“The climate and sustainability challenge can be overwhelming in the amount of new clean technology that we have to deploy and develop, and the ways that the energy system has to evolve,” said Costa Samaras, head of the university-wide Wilton E. Scott Institute for Energy Innovation. “The scale of the challenge alone can be overwhelming to folks.”

However, Carnegie Mellon University’s standing commitment to the United Nations' Sustainable Development Goals and its position as a nationally recognized leader in technologies like artificial intelligence mean that it is uniquely positioned to address growing concerns around energy demand, climate resilience and social good.
