Investigating Technology Options for Climate Policies: Differentiated Roles in ADAGE

Martin T. Ross, Patrick T. Sullivan, Allen A. Fawcett, and Brooks M. Depro

Abstract:
This paper examines a range of technological and regulatory approaches to reducing greenhouse gas (GHG) emissions. Availability of new technologies will control how the economy and energy infrastructure respond to any future climate policies. How such policies interact with other types of environmental regulations will also influence the best options for meeting emissions goals. To investigate these effects, the ADAGE model is used to examine policy impacts for several climate and technology scenarios, focusing on key factors such as emissions, technology deployment, energy prices and macroeconomic indicators. In general, the simulations indicate that reductions in GHG emissions can be accomplished with limited economic adjustments, although the impacts depend on both the regulatory approaches used and the future availability of new low-carbon technologies.

A Clean Energy Standard Analysis with the US-REGEN Model

Abstract:
A clean energy standard (CES) is a potential policy alternative to reduce carbon emissions in the electric sector. We analyze this policy under a range of technological assumptions, expanding on the Energy Modeling Forum (EMF) 24 study scenarios, using a new modeling tool, US-REGEN. We describe three innovative features of the model: treatment of spatial and temporal variability of renewable resources, cost-of-service electric sector pricing, and explicit representation of energy end-use specific capital. We find that varying technology assumptions results in vastly different futures, with large contrasts in the distribution and scale of inter-regional financial flows, and in the generation mix. We explore regional differences in how the costs of CES credits are passed through with cost-of-service vs. competitive pricing. Finally, we compare the CES to an economy-wide emissions cap. We find that although the two policies result in a similar generation mix, price and electricity end-use results differ.

Time-Frequency Spillovers and the Determinants among Fossil Energy, Clean Energy and Metal Markets

Abstract:
Using the frequency-domain spillover index method, we investigate time-frequency spillovers and their underlying drivers among fossil energy, clean energy and metal markets. We find that short-term spillovers are stronger than long-term spillovers. Global clean energy markets are powerful spillover transmitters that can have strong impacts on fossil energy and metal markets. Rare earth metals are most vulnerable to spillover effects from clean energy and base metal markets, particularly in the long term. Different clean energy sources and metal markets have heterogeneous connectedness, e.g., the impact of wind energy on rare earth market is greater than that of solar energy. The short-term spillovers are mainly driven by policy changes, while the long-term spillovers are mainly affected by stock market uncertainty and economic fundamentals. Our findings have important implications for the construction of optimal diversification strategies and the design of policy incentives to promote clean energy investments across different time horizons.
