Tradable emissions allowance systems to reduce carbon emissions are increasingly promoted as means to mitigate climate change. This paper briefly reviews the application of such systems at the global, regional, and corporate scales. Given the recent expansion of cap-and-trade systems at the...

This paper uses a static computational game theoretic model of a fully opened European electricity market and can take strategic interaction among electricity-producing firms into account. The model is run for a number of scenarios: first, in the baseline under perfect competition, the prices...

In electricity, "downstream" CO2 regulation requires retail suppliers to buy energy from a mix of sources so that their weighted emissions satisfy a standard. It has been argued that such "load-based" regulation would solve emissions leakage, cost consumers less, and provide more incentive for...

Growth in gas demand poses a challenge for European energy consumers and other gas-importing countries in terms of an increasing dependency on gas imports and consequently also supply security. This paper focuses on interactions among demand, supply, and investments in natural gas corridors,...

As part of its commitments to the Regional Greenhouse Gas Initiative (RGGI), the State of Maryland, USA, auctions emission permits to electric utilities, creating revenue that can be used to benefit consumers and the environment. This paper explores the CO2 emissions reductions that may be...

What are the economic consequences of increased state spending on electricity consumption efficiency? The State of Maryland faces this question in deciding how much of its CO2 allowances auction proceeds (under the Regional Greenhouse Gas Initiative) to devote to such programs. Starting at a...

We briefly consider the tensions between climate change and energy security policy imperatives, and highlight some concepts that may bring additional clarity to decision-making at the nexus of the two areas. We focus on developing countries and use the case of the Medupi supercritical coal plant...

In Great Britain (GB) and across Europe significant investment in electricity transmission is expected over the coming years as decarbonisation and market integration efforts are intensified. However, there is also significant uncertainty with the amount, location and timing of new generation...

Renewables require support policies to deliver the European 20% target. We discuss the requirements for least-cost development and efficient operation and quantify how different schemes (i) allow for the development of a renewable energy technology portfolio; (ii) reduce rent transfers to...
