This paper seeks to discuss some of the policy implications which arise from the modelling of Net Zero GHG emissions in 2050 within a sector coupling approach. We draw on a major study of the EU-UK energy system in 2050 produced by the Centre for Regulation in Europe (Chyong et al. 2021), which involved stakeholders…

The Influence of Shale Gas on U.S. Energy and Environmental Policy
The emergence of U.S. shale gas resources to economic viability affects the nation’s energy outlook and the expected role of natural gas in climate policy. Even in the face of the current shale gas boom, however, questions are raised about both the economics of this industry and the wisdom of basing future environmental policy on…

Contracting for Wind Generation
The UK Government proposes offering long-term Feed-in-Tariffs (FiTs) to low-carbon generation to reduce risk and encourage new entrants. Their preference is for a Contract-for-Difference (CfD) for all generation regardless of type. I argue that a standard CfD is unsuitable for on-shore wind, where a fixed FiT appears less risky. The estimated extra trading and balancing…
Solar Integration
Solar energy can enter our energy systems through many doors and windows, mostly as heat and electricity. As costs go down, especially for photovoltaic electricity, the variability of the resource becomes a dominant issue.Interconnections,load management, flexible fossil or hydro power plants and storage capacities of pumped hydro plants combine to make the daily variability manageable,…
Market and Policy Barriers to Deployment of Energy Storage
There has recently been resurgent interest in energy storage, due to a number of developments in the electricity industry. Despite this interest, very little storage, beyond some small demonstration projects, has been deployed recently. While technical issues, such as cost, device efficiency, and other technical characteristics are often listed as barriers to storage, there are…
Support Schemes for Renewable Energy: An Economic Analysis
We consider leading approaches to the decarbonisation of electricity supply. Price supports through long term contracts, such as feed-in-tariffs have been very effective at eliciting rapid escalation of renewable supply, largely because risks have been transferred away from suppliers and tariffs have been generous. However, countries with the most ambitious programs of this type (Denmark,…
