Combining Technology-Push and Demand-Pull Policies to Create More and Better Energy Jobs

| Sep. 15, 2022

Policymakers guiding their economies to a low-carbon, prosperous future must strike the right balance between technology-push and demand-pull. The rapid build-out of solar photovoltaics in recent years has revealed the benefits of generous demand-pull policies, but also their limits. In this policy brief, the authors show why combining robust demand-pull and technology-push policies results in more effective policy mixes that go beyond innovation and deployment to help competitive domestic industries create more and better jobs.

New Study Examines Drivers of Government Investment in Energy Innovation

New forms of international cooperation and technology competition with China are the main drivers of public investment in energy innovation, though it remains insufficient to help meet climate goals.

‘ColdHubs’ Enterprise Wins Harvard’s Roy Award for Environmental Partnership

| Sep. 12, 2022

The Environment and Natural Resources Program at Harvard Kennedy School’s Belfer Center for Science and International Affairs announced today that ColdHubs Limited is the winner of the 2022 Roy Family Award for Environmental Partnership. The company—born out of a partnership between the Smallholders Foundation, the Institute for Air Handling and Refrigeration (ILK Dresden), and the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ)—uses solar-powered walk-in cold rooms to reduce post-harvest losses for smallholder farmers across rural Nigeria.

California Dreaming? Nope.

In an interview with The Harvard Gazette, Henry Lee welcomes California's aggressive move toward electric vehicles, but sees one ‘huge mistake’ policymakers need to avoid and a surefire way to anger drivers.

We’ll Need Hundreds of New Critical Metals Mines to Decarbonize

| Aug. 24, 2022

Surging demand and dizzying price hikes have raised concerns that inadequate metal and mineral supplies may impede the clean energy transition. Given the urgency of reducing fossil fuel use, the science and policy worlds must solve two main challenges: how to ensure the availability and affordability of critical metals in the quantities needed, and how to manage the environmental impacts related to mining and processing them. The latter issue is likely to be much trickier than the former, argue Henry Lee and Xin Sun.

Policy Spillovers, Technological Lock-In, and Efficiency Gains from Regional Pollution Taxes in the U.S.

| December 2022

We used the US-TIMES energy-system model in conjunction with integrated assessment models for air pollution (AP3, EASIUR, InMAP) to estimate the consequences of local air pollutant (LAP) and carbon dioxide (CO2) policy on technology-choice, energy-system costs, emissions, and pollution damages in the United States. We report substantial policy spillover: Both LAP and CO2 taxes cause similar levels of decarbonization. Under LAP taxes, decarbonization was a result of an increase in natural gas generation and a near-complete phaseout of coal generation in the electric sector. Under a CO2 tax, the majority of simulated decarbonization was a result of increased electric generation from wind and solar. We also found that the timing of the CO2 and LAP taxes was important. When we simulated a LAP tax beginning in 2015 and waited until 2025 to introduce a CO2 tax, the electric sector was locked into higher levels of natural gas generation and cumulative 2010–2035 energy system CO2 emissions were 8.8 billion tons higher than when the taxes were implemented simultaneously. A scenario taxing CO2 and LAPs simultaneously beginning in 2015 produced the highest net benefits, as opposed to scenarios that target either CO2 or LAPs, or scenarios that delayed either LAP or CO2 taxes until 2025. Lastly, we found that net benefits compared to business as usual are higher under a regional versus a national LAP-tax regime, but that efficiency gains under the regional tax are not substantially higher than those under the national LAP-tax policy.

MIGHTY: Model of International Green Hydrogen Trade

| Aug. 03, 2022

The Model of International Green Hydrogen Trade (MIGHTY) is an optimization model to investigate renewable hydrogen production, consumption, and trade between countries. MIGHTY supports strategic analysis by policymakers and investors about the potential roles that countries and regions will play in future renewable hydrogen markets. This paper introduces the model and describes the model formulation.

Surging Lithium Price Will Not Impede the Electric Vehicle Boom

| July 30, 2022

The surging prices of materials, especially lithium, have stirred up wide concerns about future EV development. In this commentary, with a focus on lithium, Xin Sun and co-authors argue that although the current price spike gives the EV market a sharp short-term shock, it will not hinder transportation electrification in the long run.
