In this Q&A, Joseph S. Nye talks about his advice for the interim and future president of Harvard in the wake of Claudine Gay's resignation, which countries should be highest on our radar to prevent the threat of nuclear war, what role the U.S. should play in the Russia-Ukraine war, the significance of U.S. alliances in the Middle East, and more.

Oil prices have been persistently high over the past two years , at times breaking above $120 a barrel. According to economic theory, that should be good news for climate change. But the political reality is more complicated. Climate policies are increasingly the casualties of high oil prices.

At the foot of the Eqi Glacier in Greenland in June, I watched ice formed thousands of years ago drop into the warming ocean. With this vivid depiction of climate change in my mind, I was disappointed that neither of the conferences held last month to prepare for the UN’s upcoming COP28 summit had produced any real breakthroughs.

However, while the need for climate action is rising, the stakes for COP, perhaps counter-intuitively, look to be diminishing. An underwhelming COP28 would be a missed opportunity but it may not be a tragedy. Twenty or even 10 years ago, it was reasonable to hope a co-operative approach could address climate. But it is no longer a realistic expectation — nor the most promising route for progress.

The International Energy Agency predicted last month that demand for global oil for transport will peak around 2026, plateau for all uses by 2028, and possibly hit a zenith by the end of the decade. Harvard experts say the forecasts track with what’s going on in the developed world, but the energy needs of less-wealthy nations pressing to develop their economies could foil expectations for years to come.

The geopolitical implications of solar displacing oil as the world’s major source of energy are enormous. Why has the Middle East been a central arena in the “great game” for the past century? Because countries there have been the major suppliers of the oil and gas that powered 20th-century economies. If, over the next decade, photovoltaic cells that capture energy from the sun were to replace a substantial part of the demand for oil and gas, who will the biggest losers be? And even more consequentially: who will be the biggest winner?

As recently as 18 months ago, many policymakers, academics, and pundits in the United States and Europe were waxing lyrical about the geopolitical benefits of the coming transition to cleaner, greener energy. They understood that the move away from a carbon-intensive energy system that relied on fossil fuels was going to be difficult for some countries. But on the whole, the conventional wisdom held that the shift to new sources of energy would not only aid the fight against climate change but also put an end to the troublesome geopolitics of the old energy order.

Belfer Center experts on the U.S.-China relationship and Middle East issues shared thoughts on the significance of the unexpected Iran-Saudi Arabia agreement brokered by China. 

To keep oil flowing and diminish the U.S., Beijing brokers a deal between Iran and Saudi Arabia.

The economist and HKS professor is passionate about solving what may be humanity's most important and perplexing problem: How to untangle fossil fuels from the global economy.

On December 3, 2022, Nicola De Blasio, Senior Fellow with the Belfer Center’s Environment and Natural Resources Program (ENRP), chaired a panel discussion, “Is Hydrogen Our Future?,” at the Rome MED – Mediterranean Dialogue (Rome MED), an annual high-level conference on Mediterranean geopolitics. The panel discussion was part of ENRP’s Future of Hydrogen project’s ongoing engagement with global policymakers, who are increasingly viewing hydrogen as a solution to meeting their decarbonization and energy security goals.
