Disruption to place attachment and the protection of restorative environments: A wind energy case study

Deepening understanding of public responses to large-scale renewable energy projects is of academic and practical importance, given policies to lessen fossil fuel use in many countries. Although the NIMBY (Not In My Back Yard) concept is commonly used to explain public opposition, the concept has been extensively critiqued. This study applies an alternative approach based upon the notion of disruption to place attachment, and the theory of social representations, with a focus upon the symbolic meanings associated with a proposed project and the places affected by it. Empirical data is provided from a case study of a proposed 750 MW offshore wind farm in North Wales, using group discussions and questionnaires distributed to local residents in two coastal towns (n = 488). Results indicate significant differences between each town's residents in their responses to the project, and how opposition arises from nature/industry symbolic contradictions: between a place represented in terms of scenic beauty that provides a restorative environment for residents and visitors, and a wind farm that will industrialise the area and ‘fence’ in the bay. In one of the towns, the data suggests that contradiction between project and place was experienced as a threat to identity for those with strong place attachment, leading to negative attitudes and oppositional behaviour. Levels of trust in key actors moderated the relation between place attachment and negative attitudes to the wind farm. The results provide further evidence of the role of place attachment in shaping so-called ‘NIMBY’ responses to development proposals, and challenge the assumption that offshore wind farms will prove less controversial than those onshore.     

基于LMDI的我国能源消费因素分解研究

经济飞速发展使我国能源消费急剧增长,能源消费与能源供给、环境污染矛盾日益突出。在分析我国能源消费和能源消费强度变化趋势的基础上,运用LMDI法将我国1996--2010年能源消费变化分解为产出效应、结构效应和强度效应,探讨产出提高、结构调整、效率提高对我国能源消费和能源强度的影响。结果显示,生产规模扩大对能源消费起到正向的拉动作用,结构调整对缓解能源消费增长还有较大的上升空间,能源强度对能源消费的抑制效应自“十一五”期间起作用逐步显现。

Towards sustainable consumption: Predicting the impact of social‐psychological factors on energy conservation intentions in Northern Cyprus

The incessant demand and consumption of energy services among individuals’ is increasing throughout the world. Individuals’ electricity consumption in Northern Cyprus has risen considerably. However, the demand for electrical energy services on the island is heavily reliant on imported fossil fuels. Burning fossil fuels has adverse effects on its environment. Therefore, sustainable energy consumption is required and individuals are targeted for energy conservation to reduce electricity consumption. Against this background, using the Structural Equation Modeling approach, this research incorporates social‐psychological factors; personal norms, positive and negative emotions into the theory of planned behaviour (TPB) model to assess the relationships among the variables, explain their impact on consumers’ electricity conservation intentions and enhance the explanatory power of the model. Data was conveniently obtained from a quantitative sample of 400 electricity consumers. The results indicate that negative emotions have the strongest significant influence on intentions, but personal norms have the least effect on intentions to save electricity. Furthermore, the study revealed that our expanded TPB model can provide improved explanatory power more than the original TPB. Policy implications, limitations and future research are discussed.     

收入多样性对农户能源消费结构的影响——以陕南秦巴山区为例

为了识别农户能源消费结构影响因素,引导农村能源消费结构优化,基于陕南秦巴山区2020年调查数据,采用Tobit模型和Logit模型分析了收入多样性对该地区能源消费结构的影响,并根据农户生计策略的不同进行了异质性分析。结果表明:①农户能源消费结构中,商品能源占主导地位,生物质能源占重要地位,清洁能源消费则有待提高。②收入多样性对商品能源和清洁能源的消费有促进作用,对生物质能源的消费有抑制作用,且这一趋势在非农型农户家庭中更加明显。因此,政府可通过发展第二、三产业,完善并改进现有能源政策等方式实现陕南秦巴山区能源消费结构的转型升级。
