Al-Juaied and Whitmore examine the costs and prospects for direct air carbon capture and storage (DACCS), and identify types of funding needed for early deployment for DACCS and building momentum for later widespread deployment. The challenges of implementing DACCS at very large scale further emphasize the need for urgent and widespread action to reduce emissions, which should continue to be the main priority for meeting climate goals.

Joel Clement describes the influence of U.S. Senators Lisa Murkowski and Joe Manchin over the Department of the Interior and advises that a forward-looking legislator in a fossil-fuel state would be wise to fight aggressively for financial commitments to make the people in their state part of the vanguard of the new clean energy economy, rather than set back the U.S. economy by fighting the inevitable energy transition itself.

Joel Clement describes some immediate opportunities—and emphasize specific recommendations—to establish the Interior Department as a purposeful catalyst for a fair and just transition to clean energy, healthy ecosystems, and thriving communities.

A history of colonialism means the nation will need to carefully integrating newcomers in ways that preserve its cultural heritage.

Arctic Innovator Samuel Gant writes that by adopting world-class environmental and safety standards and creating a sovereign wealth fund, Greenland can ensure mining serves its best interests.

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.

The COVID-19 recovery response from the UK government should include increased and well-targeted R&D investments to foster the energy transition and a more sustainable economy.

The authors recount the history of ARPA-E and describe how it has supported clean energy innovation in the United States. They argue that ARPA-E needs two things in the short term in order to increase its chances of success in the long term: resources and a leader who can channel the country's top science and engineering talent toward particularly tough technical challenges.

After many years of productive service, industrial plants reach the end of their useful life and must be dismantled. This complex and costly process, know as decommissioning (commissioning refers to the beginning of a plant useful life), is a confluence of economic, environmental, physical, and regulatory challenges.
