摘要： Plug-in hybrid electric vehicles (PHEVs) offer the potential to significantly reduce greenhouse gas emissions, if vehicle consumers are willing to adopt this new technology. Consequently, there is much interest in exploring PHEV market penetration models. In prior work, we developed an agent-based model (ABM) of potential PHEV consumer adoption that incorporated several spatial, social, and media influences to identify nonlinear interactions among potential leverage points that may impact PHEV market penetration. In developing that model, the need for additional data to properly inform both the decision-making rules and agent initialization became apparent. To address these issues, we recently conducted and analyzed an extensive consumer survey; in this paper, we modify the ABM to reflect the survey findings. A unique aspect is a one-to-one correspondence between agents in the model and survey respondents, and thus yielding distributions and cross correlations in agent attributes that accurately reflect the survey population. We also implement a used-PHEV market, and allow agents to purchase new or used compact PHEVs or vehicles of their current type. Based on our prior survey response analysis, our modified model includes a PHEV-technology threshold component, a multinomial logistic prediction of willingness to consider a compact PHEV based on dynamically changing attitudes, and agent-specific delay discounting functions that predict the amount agents are willing to pay up front for greater fuel savings. We thus independently account for agents’ discomfort with the new PHEV technology, their desire to drive a more environmentally friendly vehicle, and their willingness to pay a higher sticker price for a PHEV. Results of ten survey-based ABM scenarios are reported with implications for policy-makers and manufacturers. We believe close integration of the design of consumer surveys and the development of ABMs is a key step in developing useful decision-support models; this paper serves as an example of one way to achieve that.

Surveying the Solar Power Gap: Assessing the Spatial Distribution of Emerging Photovoltaic Solar Adoption in the State of Georgia, U.S.A.
摘要： Despite a global push in the development and implementation of widespread alternative energy use, significant disparities exist across given nation-states. These disparities reflect both technical and economic factors, as well as the social, political, and ecological gaps between how communities see energy development and national/global policy goals. Known as the “local-national gap”, many nations struggle with fostering meaningful conversations about the role of alternative energy technologies within communities. Mitigation of this problem first requires understanding the distribution of existing alternative energy technologies at the local level of policymaking. To address the limitation of existing adoption trend analysis at the scale of local governance (e.g., county governments), this paper demonstrates a novel method for contextualizing solar technology adoption by using the State of Georgia in the United States as an exemplar. Leveraging existing work on the Gini Coefficient as a metric for measuring energy inequity, we argue these tools can be applied to analyze where gaps exist in ongoing solar adoption trends. As we demonstrate, communities that adopt solar tend to be concentrated in a few counties, indicating existing conversations are limited to a circumscribed set of social networks. This information and the model we demonstrate can enable focused qualitative analyses of existing solar trends, not only among high-adoption areas but within communities where little to no adoption has occurred.

Motives for solar photovoltaic (PV) adoption in urban Nigeria
摘要： Microgeneration technologies like residential solar photovoltaic (PV) systems have been shown to have immense potential for energy security and climate change mitigation. At over 50% private power systems ownership, the majority of urban Nigerian households rely on conventional self-generation utilising expensive petrol and diesel-powered generators. Despite the high upfront costs of a sizeable PV module, some households are choosing such sustainable alternative power. This paper investigates the motives for PV adoption in urban Nigeria following innovation diffusion and adoption theories. Using interviews, PV adopter data were collected on key drivers for uptake and results analysed. Field survey analysis established the key motives for uptake as power outages, energy cost-savings, including generator use fuel fraud, awareness and access to finance while key barriers include high capital costs and lack of finance. The results point to the need for regulatory and political intervention. Effective PV awareness creation campaigns and promotional strategies would also be necessary in the changing face of electricity supply in Nigeria.

Community Solar as an Innovative Business Model for Building-Integrated?Photovoltaics An Experimental Analysis with Swiss Electricity Consumers
摘要： A currently pertinent research challenge is to find ways to keep the growth rate of solar power at a high level. The adoption of new technologies, such as building-integrated photovoltaics (BIPV), but also new and innovative business models such as community solar, have both been identified as relevant drivers. However, the adoption of BIPV is still encountering numerous barriers that hinder its more widespread deployment within the solar PV market. The goal of this research effort was to assess whether community solar as a successful business model for the adoption of conventional solar PV could be equally promising in relation to the further adoption of BIPV. For this purpose, we conducted an experimental survey (n=413) to compare customers‘ willingness to buy a community solar offer exclusively associated with BIPV to a community solar offer solely designed with conventional rooftop solar PV. Our results revealed no significant difference between willingness to buy based on our experimental treatment (BIPV vs. conventional PV), indicating that community solar can be a successful distribution channel for the further adoption of BIPV. As findings about specific business models for BIPV are rare, our research creates an important foundation upon which policy makers and project developers can build.

Energy Storage Application in Improving Distribution Network’s Solar Photovoltaic (PV) Adoption Capability
摘要： In this paper, the study is centered on the high penetration of distributed solar photovoltaic (PV) integrated into the distribution network and measures to improve its adoption capability, especially in the context of energy internet development. For this purpose, a model is proposed, where the effects of energy storage to improve the distribution network’s PV penetration level are evaluated. And a specific city distribution network in China as well as its load and PV outputs data of a typical year are chosen to certificate the effectiveness of the proposed model and method.
