The Global Energy Challenge: A Moral Imperative for the University Featuring: Dr. Daniel G. Nocera, Patterson Rockwood Professor of Energy Harvard University Climate change is an existential threat to society as we continue to meet energy demand with carbon-based fuels. Energy demand is set to grow in the coming decades, mostly driven by 3 billion people currently without access to reliable energy and an anticipated 3 billion new inhabitants of our planet by mid-century. Increasing global living standards, expanding access to education, and improving health outcomes are all inextricably linked to a need for greatly increasing access to affordable, reliable energy. Meeting this future global energy need for 6 billion new energy consumers, together with current energy users, with the expanded use of fossil fuels is inconsistent with a low-risk climate pathway; and yet, those fuels often remain the most affordable and widely available despite continued declines in the costs for zero-carbon energy technologies.
