Joseph Nye writes that the world is increasingly obsessed with the ongoing power struggle between the United States and China. But the technology-driven shift of power away from states to transnational actors and global forces brings a new and unfamiliar complexity to global affairs.

The authors argue that more determined efforts to globalize renewable energy transmission can confer significantly higher economic and environmental benefits from renewables on billions of people. This can be done by exploiting spatial differences between electricity loads and net renewable generation across time zones (temporal arbitrage) and latitude (seasonal arbitrage). Using very long distance, ultra-high voltage (UHV) transmission infrastructure, temporal and spatial arbitrage can move low-cost clean electricity from areas with excess capacity to high demand zones in other countries and even continents.

Harvard University has created a Presidential Committee on Sustainability (PCS) to advise President Larry Bacow and the University's leadership on sustainability vision, goals, strategy, and partnerships. The Harvard Gazette spoke with committee chairs Rebecca Henderson, the John and Natty McArthur University Professor; John Holdren, the Teresa and John Heinz Professor of Environmental Policy at Harvard Kennedy School; and Katie Lapp, executive vice president, about why it is so important to act now; the role of the PCS in developing collaborative and innovative projects; and how the campus community can get involved.

The Policy and Action on Plastic in the Arctic Ocean workshop was held at the Harvard Kennedy School on 30–31 October 2019. The speakers' bios and presentations are now available.
