Why Arctic Nations Should Invest in a Network of Green Ports

Climate change is opening Arctic sea lanes. With timely investment in green infrastructure, that could mean fewer — not more — emissions. Electrified ports would catalyze the greening of global shipping by supporting electric ships, a technology already benefiting from innovation.

How to Globalize Clean Energy

| June 20, 2020

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.

Reflecting on Solar Geoengineering, with David Keith

| May 12, 2020

In this episode of Resources Radio, host Daniel Raimi talks with David Keith, a physics and public policy professor at Harvard University and one of the world's leading experts on solar geoengineering. Keith outlines prominent examples of solar geoengineering technologies in development—from ambitious ideas, such as sending aerosols to the stratosphere, to more operational solutions, like painting roofs white to reflect more sunlight into space. An advocate for research on solar geoengineering, Keith discusses how coalitions among like-minded nations and clearer guidance from policymakers could expand deployment of promising technologies.

Illuminating Homes with LEDs in India: Rapid Market Creation Towards Low-carbon Technology Transition in a Developing Country

| August 2020

This paper examines a recent, rapid, and ongoing transition of India's lighting market to light emitting diode (LED) technology, from a negligible market share to LEDs becoming the dominant lighting products within five years, despite the country's otherwise limited visibility in the global solid-state lighting industry.

The study of existential risk — the risk of human extinction or the collapse of human civilization — has only recently emerged as an integrated field of research, and yet an overwhelming volume of relevant research has already been published. To provide an evidence base for policy and risk analysis, this research should be systematically reviewed. In a systematic review, one of many time-consuming tasks is to read the titles and abstracts of research publications, to see if they meet the inclusion criteria. The authors show how this task can be shared between multiple people (using crowdsourcing) and partially automated (using machine learning), as methods of handling an overwhelming volume of research.

The Overwhelming Case for No First Use

| Jan. 13, 2020

The arguments in favor of the United States' declaring that the only purpose of its nuclear weapons is to deter others who possess them from using theirs — in other words, that in no circumstances will this country use nuclear weapons first — are far stronger than the arguments against this stance. It must be hoped that the next US administration will take this no-first-use step promptly.
