Understanding Why Utilities Are Moving Towards Residential Demand Pricing and Analyzing Effectiveness in Methods of Communication

An increasing amount of utilities are moving towards residential demand pricing, causing much controversy and miscommunication between the provider and the consumer as to what demand pricing is, and what it entails for the consumer. This paper will analyze the effectiveness of utility-consumer communication methods and how Arizona utility companies (Salt River Project and Arizona Public Service) have migrated the obstacles of TOU (Time of Use) pricing changes to Arizona utility residents, especially to solar customers. SRP (Salt River Project) and APS (Arizona Public Service) have both implemented pilot programs including the E-27 for SRP and the Saver Choice Plus plan for APS . Both programs, along with international programs, have seen varying levels of success for their business and for consumers to grasp peak-demand pricing and usage. Overall, APS customers have seen an average increase of 4.5% on their electricity bills while SRP customers have experienced, on average, a $19.00 increase. Despite these bill increases, both utilities have seen a decrease in customer electricity demand in response to higher energy costs during peak times.

Prior research has established a relation between parenting behaviors and symptoms of child psychopathology, and this association may be influenced by both genetic and environmental factors. Gene-environment correlation, or the influence of a child’s genes on the environment they receive, represents one possible mechanism through which genes and environment combine to influence child outcomes. This study examined evocative gene-environment correlation in the relation between parenting and symptoms of child psychopathology in a sample of 676 twins (51.5% female, 58.5% Caucasian, 23.7% Hispanic/Latinx, primarily middle class, MAge=8.43, SD=.62) recruited from Arizona birth records. Using univariate ACE twin biometric models, genetic influences were found to moderately contribute to internalizing symptoms (A=.47, C=.25, E=.28), while externalizing (A=.86, E=.14) and ADHD (A=.84, E=.16) symptoms were found to be highly heritable. The genetic influences for positive (C=.54, E=.46) and negative (C=.44, E=.56) parenting were smaller and found to be nonsignificant. The correlations between parenting and types of psychopathology were examined and bivariate Cholesky decompositions were conducted for statistically significant correlations. Negative parenting was moderately positively correlated with externalizing and ADHD symptoms; the relation between externalizing symptoms and negative parenting was found to be due to shared genetics, whereas the relation between negative parenting and ADHD symptoms was due to the shared environment. The mixed results regarding the role of gene environment correlation in relations between parenting and child psychopathology indicate that further research on the mechanisms of this relation is needed.
