"Willingness to Pay for Electric Vehicles and their Attributes"
This article presents a stated preference study of electric vehicle choice using data from a national survey. We used a choice experiment wherein 3029 respondents were asked to choose between their preferred gasoline vehicle and two electric versions of that preferred vehicle. We estimated a latent class random utility model and used the results to estimate the willingness to pay for five electric vehicle attributes: driving range, charging time, fuel cost saving, pollution reduction, and performance. Driving range, fuel cost savings, and charging time led in importance to respondents. Individuals were willing to pay (wtp) from 75 for a mile of added driving range, with incremental wtp per mile decreasing at higher distances. They were willing to pay from 3250 per hour reduction in charging time (for a 50 mile charge). Respondents capitalized about 5 years of fuel saving into the purchase price of an electric vehicle. We simulated our model over a range of electric vehicle configurations and found that people with the highest values for electric vehicles were willing to pay a premium above their wtp for a gasoline vehicle that ranged from 16,000 for electric vehicles with the most desirable attributes. At the same time, our results suggest that battery cost must drop significantly before electric vehicles will find a mass market without subsidy.Electric Vehicles, Stated Preference, Discrete Choice
"Can Vehicle-to-Grid Revenue Help Electric Vehicles on the Market?"
Vehicle-to-grid (V2G) electric vehicles can return power stored in their batteries back to the power grid and be programmed to do so at times when power prices are high. Since providing this service can lead to payments to owners of vehicles, it effectively reduces the cost of electric vehicles. Using data from a national stated preference survey (n = 3029), this paper presents the first study of the potential consumer demand for V2G electric vehicles. In our choice experiment, 3029 respondents compared their preferred gasoline vehicle with two V2G electric vehicles. The V2G vehicles were described by a set of electric vehicle attributes and V2G contract requirements such as ârequired plug-in timeâ and âguaranteed minimum driving rangeâ. The contract requirements specify a contract between drivers and a power aggregator for providing reserve power to the grid. Our findings suggest the V2G concept is mostly likely to help EVs on the market if power aggregators operate on pay-as-you-go-basis or provide consumers with advanced cash payment (upfront discounts on the price of EVs) in exchange for V2G restrictions.electric vehicles, vehicle-to-grid, stated preference, latent-class model
Place Meaning and Consistency with Offshore Wind: An Island and Coastal Tale
This work continues a series of analyses using surveys of local communities regarding the Block Island Offshore Wind Project. Data collection focused on island and coastal resident attitudes toward the project and cognitions of the coastal setting. We report results from the first and final surveys. Multivariate statistical analysis was used to evaluate relationships among variables. Results indicate that attitudes about the project have solidified as more people have seen it. A majority support the project, and a small percent consider the project inconsistent with specific meanings associated with the ocean environment. These meanings stand out amongst other place constructs. Furthermore, the relationship among turbine descriptions and place meanings and their consistency with the project as a use of the ocean, along with general support for the project is explored. The results continue to validate a place-based understanding of the responses of people to a changing energy landscape
Faring Well in Offshore Wind Power Siting? Trust, Engagement and Process Fairness in the United States
Although visual effects may be the most defining characteristic of a wind project, implementing fair, transparent and just decision-making processes may be a significant determining factor in success. To shed light on this question, we undertook a study of perceptions of mainland coastal and island residents proximate to the Block Island projectâthe first offshore wind project in the United States. The study included a longitudinal survey of residents prior to and after turbine installation, and semi-structured interviews with residents and key stakeholders. We assessed the extent to which respondents were engaged in the planning process, opinions of transparency and fairness, and degree to which the planning process affected their opinion. Although interviewees who held a negative view of state government indicated that it did not cause them to oppose the project, trust in state government was the primary driver of perceptions of process fairness, which in turn was the primary driver of project support. We also found individuals to withhold final judgment of the process until the final outcomeâproject operation. Finally, fair process was seen as having benefits distinct from its effect on the outcomeâthat is, local residents valued the process itself
Vehicle to Grid Demonstration Project
This report summarizes the activities and accomplishments of a two-year DOE-funded project on Grid-Integrated Vehicles (GIV) with vehicle to grid power (V2G). The project included several research and development components: an analysis of US driving patterns; an analysis of the market for EVs and V2G-capable EVs; development and testing of GIV components (in-car and in-EVSE); interconnect law and policy; and development and filing of patents. In addition, development activities included GIV manufacturing and licensing of technologies developed under this grant. Also, five vehicles were built and deployed, four for the fleet of the State of Delaware, plus one for the University of Delaware fleet
Reassessing the effect of colour on attitude and behavioural intentions in promotional activities: The moderating role of mood and involvement
The present research examines the effect of background colour on attitude and behavioural intentions in various promotional activities taking into consideration the moderating role of mood and involvement. Three experiments reflecting different promotional activities (window display, consumer trade show, guerrilla marketing) were conducted for this purpose. Overall, findings indicate that cool background colours, in contrast to warm colours, induce more positive attitudes and behavioural intentions mainly in positive mood, and low involvement conditions. Implications are also discussed
Wind in the sails or choppy seas?: People-place relations, aesthetics and public support for the United Statesâ first offshore wind project
The primary social challenge of offshore wind power development may be local community membersâ struggle to come to terms with the transformation of the ocean. In this study of local residentsâ perceptions of the first wind power project off the North American coast, we consider whether factors such as aesthetics and place attachment, dependency and identity might serve as barriers or gateways toward an offshore wind power future. Respondents are 420 coastal Rhode Island and Block Island residents who were randomly sampled by mail or internet prior to turbine installation and after project commissioning. Data were analysed using weighted descriptive statistics and multiple imputed regression analysis. 87% of respondents who live in census tracts bordering the coast support or lean toward supporting the project despite paying significantly above-market prices for the electricity generated. Regression models show that support for the project is influenced, at least in part, by general disposition toward wind power and whether a respondent likes the turbinesâ appearance, with place-related measures having less influence. Descriptions of the wind turbines that resonated with supporters and opponents include respectively, âSymbolic of progress towards clean energyâ and âCause the loss of something intangible, where all you see is the oceanâ
