The D4 RIN is the tradable compliance certificate for the biomass-based diesel mandate in the Renewable Fuel Standard (RFS). Understanding the price dynamics of the D4 RIN is important for understanding the RFS because its price sets a ceiling on the ethanol RIN (D6) and because some observers...

Our new analytical general equilibrium model is used to study effects of tightening state Renewable Portfolio Standards (RPS) on electricity price, CO2 emissions, fossil fuel electricity generation, and two kinds of renewable generation. We show how those outcomes depend on key state...

We develop a dynamic competitive equilibrium model of battery adoption and operations to evaluate the social value and adoption trajectory of utility-scale batteries and examine policy counterfactuals. The first battery unit breaks even in 2027 when renewable energy share reaches 52% and...

Green energy is produced by relationship-specific assets that are vulnerable to hold-up if contracts are not strictly enforced. I study the role of counterparty risk in the procurement of green energy using data on the universe of solar procurement auctions in India. The Indian context allows...

Growing amounts of intermittent renewable generation capacity substantially increases the complexity of determining whether sufficient energy will be available to meet hourly demands throughout the year. As the events of August 2020 in California and February 2021 in Texas demonstrate, supply...

Electric vehicles (EVs) powered by renewable electricity are a centerpiece of efforts to decarbonize transportation. EV advocates also claim benefits from local pollution reductions, lower life-cycle costs to consumers, and improved energy security. We examine the theory and evidence behind...

Effective and economical expansion of renewable energy is one of the most urgent and important challenges of addressing climate change. However, many countries are facing a problem because existing network infrastructures (i.e., transmission networks) were not originally built to accommodate...

Decarbonization and electrification will require a transformed electricity grid. Our long-run model of entry and exit of generation and storage capacity captures crucial aspects of the electricity industry such as time-varying demand for electricity, intermittency of renewables, and...

After a boom and bust cycle in the early 2010s, venture capital (VC) investments are, once again, flowing towards green businesses. In this paper, we use Crunchbase data on 150,000 US startups founded between 2000 and 2020 to better understand why VC initially did not prove successful in funding...

Policies supporting investment in renewable electricity have been a cornerstone of climate policy in many parts of the world. While previous empirical work explores the economic and environmental impacts of renewable production, the focus has exclusively been on the short-run impacts of...
