Estimating the environmental and economic effects of widespread residential pv adoption using gis and nems

摘要

This paper describes a study of the national effects of widespread adoption of grid-connected residential roof-top photovoltaic (PV) systems. A Geographic Information System (GIS) model is used to estimate potential PV system adoption and PV electricity generation and the National Energy Modeling System (NEMS) is used to estimate the national effects of PV electricity generation. Adoption is assumed to occur if levelized PV system cost is less than the local average retail electricity rate at a countylevel. Our estimate of the current 'best' scenario (defined by a 6.5percent real interest rate, 30 year loan life, 6
