我们研究了人们的偏好，以支持一个可再生能源计划，种植海藻生产沼气，使用选择实验。参与者必须在三个备选方案中选择一个，其中两个是海藻方案的变体，第三个是维持现状。这两个备选方案是根据四个属性确定的：供电家庭的数量、用于养殖海藻的海岸线的百分比、它们将产生的额外成本以及额外津贴，这些都是为了鼓励人们参与该方案而增加的。选择实验是在英格兰、苏格兰和北方爱尔兰的2016名受访者中在线进行的。海藻可再生能源计划为85，000户家庭提供电力，覆盖英国20%的海岸线，英格兰每年16磅，苏格兰每年16磅，北方爱尔兰每年14磅。我们发现，人们愿意使用更多的海岸线来养殖海藻，以便为更多的家庭供电。也就是说，他们愿意在海藻养殖场造成的视觉不适和生产更多的绿色能源之间做出权衡。最后，这两项福利对人们使用海藻作为沼气的偏好产生了负面影响。
We studied people's preferences to support a renewable energy programme to grow seaweed for biogas production, using a choice experiment. Participants had to choose one among three alternatives, two of which were variations of a seaweed programme and the third was the status quo. The two alternatives were defined in terms of four attributes: the number of households powered, the percentage of coastline used to farm seaweed, the additional cost they would incur and perks, which were added to encourage people to participate in the programme. The choice experiment was conducted online in England, Scotland and Northern Ireland among 2016 respondents. The compensating variation from a renewable energy programme from seaweed that powers 85,000 households and covers 20% of the UK coastline is 16 pound per year in England, 16 pound per year in Scotland and 14 pound per year in Northern Ireland, respectively. We find that people are willing to use more coastline to farm seaweed in order to power more households. That is, they are willing to make a trade-off between the visual disamenity caused by the seaweed farms and producing more green energy. Lastly, both perks have negative effects on people's preferences for using seaweed as biogas.
