Biofuels and the Water-Energy Nexus: Perspectives for the United States

This paper provides an overview on the main impacts of biofuels production on water resources within the United States, with an emphasis on the corn-based ethanol market and the agricultural stage. The following issues are examined:

  • the relationship between biofuel production and water availability;
  • trends and policy options for future biofuel production and the tradeoffs for water scarcity;
  • technological changes in transportation fleet, with consequential effects on biofuels demand and water resources;
  • considerations for policy makers who seek to reduce the future impact of biofuels on water sustainability.

Geopolitical and Market Implications of Renewable Hydrogen: New Dependencies in a Low-Carbon Energy World

| March 2020

To accelerate the global transition to a low-carbon economy, all energy systems and sectors must be actively decarbonized. While hydrogen has been a staple in the energy and chemical industries for decades, renewable hydrogen is drawing increased attention today as a versatile and sustainable energy carrier with the potential to play an important piece in the carbon-free energy puzzle. Countries around the world are piloting new projects and policies, yet adopting hydrogen at scale will require innovating along the value chains; scaling technologies while significantly reducing costs; deploying enabling infrastructure; and defining appropriate national and international policies and market structures.

What are the general principles of how renewable hydrogen may reshape the structure of global energy markets? What are the likely geopolitical consequences such changes would cause? A deeper understanding of these nascent dynamics will allow policy makers and corporate investors to better navigate the challenges and maximize the opportunities that decarbonization will bring, without falling into the inefficient behaviors of the past.

Russia's Energy Foray into Asia: Implications for U.S. Interests

| Dec. 12, 2018

This essay examines Russia’s growing role in Asia’s energy markets, assesses the implications for the U.S., and examines the claim that closer Sino-Russian energy ties are adding new incentives for a broader strategic alignment.

American Nuclear Diplomacy

| August 4, 2016

In this report, American Nuclear Diplomacy: Forging a New Consensus to Fight Climate Change and Weapons Proliferation, Former Deputy Secretary of Energy and Belfer Center Senior Fellow Daniel Poneman writes that we face two existential threats: nuclear annihilation and catastrophic climate change. Each, he says, stems from human origins. Both must be fought aggressively.

"Multiple studies confirm the grim truth that, even if all nations fulfill their Paris Climate Agreement emissions pledges, the world will still far overshoot the 2°C warming limit scientists say we must not exceed to prevent devastating climate impacts. Carbon-free nuclear energy can help close the gap. But can we expand its environmental benefits without increasing the risks of nuclear terror?"

Poneman outlines a diplomatic strategy and tough-minded, bipartisan policies to get us there.

Crafting Usable Knowledge for Sustainable Development

| 2016

This paper distills core lessons about how researchers (scientists, engineers, planners, etc.) interested in promoting sustainable development can increase the likelihood of producing usable knowledge. We draw the lessons from both practical experience in diverse contexts around the world, and from scholarly advances in understanding the relationships between science and society.

A Spatiotemporal Exploration of Water Consumption Changes Resulting from the Coal-to-Gas Transition in Pennsylvania

| January 2016

During the early stages of Pennsylvania's coal-to-gas transition, extraction and generation of coal and natural gas contributed to a yearly 2.6–8.4% increase in the state's water consumption. Although some areas experienced no change in water consumption, others experienced large decreases or increases. Consumption variations depended on available natural gas resources and pre-existing power-generating infrastructure. This analysis estimates monthly water consumption associated with fuel extraction and power generation within Pennsylvania watersheds between 2009 and 2012. It also provides the first comprehensive representation of changing water consumption patterns associated with the state's coal-to-gas transition at the sub-basin level.

The Future of Low-Carbon Road Transport: What Role for Second-Generation Biofuels?

| June 2015

The promise, prospects, and public policy trade-offs related to second-generation biofuels in road transport were addressed in an executive session convened at The Henry Ford Museum in Dearborn, Michigan, on April 7 and 8, 2015. The workshop brought together twenty-eight of the world's leading experts from the fields of policy, science, and business for an intensive two-day session. This report is a summary of the main points and issues raised over the two days. It has been reviewed by all the participants. The summary is intended to reflect the breadth of the discussion, rather than to suggest any form of overall consensus among the participants.

Carbon Sequestration in the U.S. National Parks: A Value Beyond Visitation

| February 2015

This discussion paper examines the potential role U.S. National Parks play in curbing greenhouse-gas (GHG) emissions through carbon sequestration—the process of moderating global climate change by removing carbon dioxide from the atmosphere and storing it in long-term mineral, organic, and oceanic reservoirs.

Commercializing Second-Generation Biofuels: Scaling Up Sustainable Supply Chains and the Role of Public Policy

The promise, prospects, and public policy trade-offs related to the greater use and production of second-generation biofuels were addressed in an executive session convened by the Harvard Kennedy School on November 13 and 14, 2014. The session attracted more than 25 of the world's leading experts from the fields of policy, science, and business for an intensive two day session. The agenda consisted of three sessions focused on (i) the sustainability of cellulosic supply chains, (ii) government policy options to attract investment and (iii) government policy options to ensure that environmental objectives are met.
