Harnessing electricity retail tariffs to support climate change policy

The 6th World Congress of Environmental and Resource Economists (WCERE 2018), Gothenburg, Sweden, 25-29 June 2018Legacy electricity retail tariffs are ill-adapted to future electricity systems and markets, particularly with regard to accommodating the multi-faceted shift toward decarbonisation. We examine how retail tariffs need to be reformed to not only meet the future revenue requirements of energy-suppliers and networks but also to help achieve the environmental objectives of the energy transition. While existing literature has explored the link between retail tariff structure design, wholesale markets and/or network cost recovery, there is less recognition of the impact of tariff structure design on environmental objectives. This paper reviews the demand responsiveness of household customers to electricity prices and implications of retail tariff structure and design for the policy targets of CO2 emissions, energy efficiency, and renewable electricity generation, in addition to electricity system. A review of the literature provides a theoretical basis for price elasticity of demand and electricity retail tariff design, and we explore the environmental implications for future retail tariff design options via examples of various tariff structures in the EU and US. The research links the topics of emissions mitigation policy and market design, and should add empirical insights to the body of academic literature on future electricity markets. It should also be of interest to policy makers wishing to consider retail tariff structures that promote decarbonisation of the electricity system through multiple objectives of improved energy efficiency and increased shares of renewable electricity within future electricity markets.Science Foundation IrelandEnergy Systems Integration Partnership Programme (ESIPP) UCDDepartment of the Environment, Climate and CommunicationsEnter two RePEc numbers if the item appears in more than one collection or series.

Linking Retail Electricity Pricing and the Decarbonisation of the Energy Sector: a Microeconomic Approach

In this paper we address the problem of policy coordination in the electricity sector when the supply side is subject to a carbon constraint. We specifically evaluate the link between retail electricity pricing and GHG emissions reduction. Moreover, we incorporate in the analysis both the variability of electricity demand and the uncertainty of clean energy supply. By developing an analytical framework grounded in the standard microeconomic theory, we model peak pricing, block pricing and real time pricing from the perspective of a representative consumer. We then estimate the impact of each pricing scheme on the social welfare function, with a specific focus on the external cost function where GHG emissions are explicitly accounted for. We find that the impact of peak and block pricing on the carbon emissions form the electricity sector is strongly influenced by the relative emissions intensity of baseload and peak generation. In contrast, the role of real time pricing as an environmental policy tool depends on the possibility for retail customers to discriminate their consumption over the quality and price of the electricity demanded

Evaluation of Pump Discontinuation and Associated Factors in the T1D Exchange Clinic Registry.

BackgroundThe objectives of this study were to examine factors associated with insulin pump discontinuation among children and adults followed longitudinally for 1 year in the multicenter T1D Exchange clinic registry, and to provide participant-reported reasons for stopping pump therapy.MethodsWe longitudinally followed 8935 participants of all ages using an insulin pump at the time of registry enrollment. Logistic regressions were used to identify demographic and clinical factors associated with pump discontinuation. Pump discontinuation was self-reported by participants on a first annual follow-up survey.ResultsThe overall frequency of pump discontinuation was 3%. Discontinuation was higher in adolescents (4%) and young adults (4%) than in younger children (3%) or older adults (1%). In multivariate analysis of children between 6 and <13 and 13 and <18 years, participants who discontinued pump use were more likely to have higher HbA1c levels at baseline (adjusted P < .001 for both). The top participant-reported reasons for discontinuing the pump included problems with wearability (57%), disliking the pump or feeling anxious (44%), and problems with glycemic control (30%).ConclusionsIn T1D Exchange registry participants, insulin pump discontinuation is uncommon, but more prevalent among adolescents and young adults, and youth with poor glycemic control. Given the known benefits of pump therapy, these populations should be targeted for support and education on troubleshooting pump use. Common reasons for discontinuation should also be considered in future device design and technological improvement

Blockade of interleukin 1 in type 1 diabetes mellitus

Interleukin 1 (IL-1) is a 17 kDa protein highly conserved through evolution and is a key mediator of inflammation, fever and the acute-phase response. IL-1 has important functions in the innate immune defense against microbes, trauma and stress, and is also an effector molecule involved in tissue destruction and fibrosis. The inhibition of IL-1 action has clinical efficacy in many inflammatory diseases, such as hereditary autoinflammatory disorders, familial hereditary fever, gout, rheumatoid arthritis and type 2 diabetes mellitus (T2DM). The latter is a common metabolic condition caused by insulin resistance and pancreatic beta-cell failure, the causes of both of which have inflammatory components. IL-1 signaling has roles in beta-cell dysfunction and destruction via the NFkappaB and mitogen-activated-protein-kinase pathways, leading to endoplasmic reticulum and mitochondrial stress and eventually activating the apoptotic machinery. In addition, IL-1 acts on T-lymphocyte regulation. The modulating effect of IL-1 on the interaction between the innate and adaptive immune systems and the effects of IL-1 on the beta-cell point to this molecule being a potential interventional target in autoimmune diabetes mellitus. Genetic or pharmacological abrogation of IL-1 action reduces disease incidence in animal models of type 1 diabetes mellitus (T1DM) and clinical trials have been started to study the feasibility, safety and efficacy of IL-1 therapy in patients with T1DM. Here, we review the rationale for blocking IL-1 in patients with T1DM
