In this paper we discuss the concept of climate debt, which measures the cumulative economic damages due to CO2 emissions. We find that the climate debt (estimated for 131 countries) is extremely large, equaling some $59 trillion over the 1959–2018 period. Climate debt is also substantial relative to other government liabilities; in the G-20, it…
Cheap Money, Geopolitics and Supernormal Backwardation of the WTI Forward Curve
Financial speculators frequently trade in the most liquid short-tenor contracts. We study repeating patterns of sharply steepening slopes in the WTI forward curve to investigate whether, after controlling for macroeconomic variables, physical market fundamentals, and basic arbitrage, calendar spread behavior is partly explained by speculation related to assessed geopolitical risk. We estimate WTI forward curve…
Incentive Regulation of Electricity and Gas Networks in the UK: From RIIO-1 to RIIO-2
The regulatory and operating context of energy networks is dynamic and constantly evolving. Achieving a multitude of economic, environmental, social and policy objectives is a challenging task for the sector regulators. In 2010, the UK energy regulator Ofgem replaced its approach to energy network price control and incentive regulation with a Revenue-Incentive-Innovation-Output (RIIO-1) model. This…
Different Cost Perspectives for Renewable Energy Support: Assessment of Technology-neutral and Discriminatory Auctions
Auctions are the prevalent instrument for promoting renewable energy sources worldwide, especially in the European Union and in Latin America. Auctions enable the controlled deployment of renewable energy sources while reducing costs. However, there are different views on relevant costs, auction targets, and their implications on the auction design. Here, the application of technology-neutral auctions…
Promoting Large and Closing Small in China’s Coal Power Sector 2006–2013: A CO2 Mitigation Assessment Based on a Vintage Structure
In the period 2006-2013, China’s power sector adopted a policy which aimed to add large scale units (larger than 600 MW) and decommission small, old (but still technically functioning) and inefficient power plants in order to accelerate energy saving and mitigate emissions. The early-retirement (ER) of nearly 90 GW of capacity and massive new coal…
Assessing the viability of Energy-Only Markets with 100% Renewables
Abstract – Efficient wholesale electricity markets should drive preference revealing bidding where generators offer the majority of their power at their short run marginal cost (SRMC). However, most renewables have very low SRMCs, which in a competitive market is likely to lead to an increasing proportion of low priced periods. Combined with concerns around the…
Measuring Energy Efficiency: Accounting for the Hidden Costs of Product Failure
Several recent studies suggest that minimum energy efficiency standards for appliances have resulted in higher-quality products with little or no increase in price. We have conducted case studies for the two major household appliances—clothes washers and refrigerators—subject to Department of Energy (DOE) energy efficiency standards implemented over the 2001 to 2011 period. We identify three…
Projecting Energy and Climate for the 21st Century
The growing evidence of severe climate change impacts on human life and the global economy has created the increasing need for an assessment of low-carbon pathways. While the ultimate goal of zero- or near-zero global emissions is clear, the timing and trajectory to achieve low-carbon economic system is not. Projecting energy and climate is getting…

On the Techno-economic Benefits of a Global Energy Interconnection
The discussion about the benefits of a global energy interconnection is gaining momentum in recent years. The techno-economic benefits of this integration are broadly discussed for the major regions around the world. While there has not been substantial research on the techno-economic benefits, however, some initial results of the global energy interconnection are presented in…
