Summary/Abstract

This paper investigates how Korean government support affects household adoption of renewable energy-based micro-generation systems by analyzing household preferences in relation to the costs and benefits of system installation and different kinds of government support. The research adopts a discrete choice experiment approach and focuses on two micro-generation technologies: solar voltaic and solar thermal. Our empirical analysis revealed firstly that households prefer micro-generation systems that have low installation costs but high energy saving benefits and long warranty periods; and secondly that households prefer direct subsidies to low-interest loans. However, we also found that households are reluctant to install photovoltaic or solar thermal systems in reality because they see the cost of system installation as being higher than the benefits they would receive from such installation. In short, while existing government supports are somewhat effective in promoting household adoption of micro-generation systems, there also exists the obstacle that the majority of households are unwilling to install such systems despite government support. Thus several policy improvements, which focus on increasing the benefits and decreasing the installation costs of micro-generation systems, are suggested in this paper.

Summary/Abstract

This paper seeks to evaluate the effect of the upcoming 2010 UK Feed-in Tariff (UK FIT) on decentralised small wind-energy installations at the household and building level in urban locations. It is projected that the UK FIT will stimulate an unprecedented surge in building-mounted turbine installation. The tariff amount must stimulate incentive but mitigate the likelihood of distortions in the competitive electricity market. To analyse these issues, measured energy output from sites in the Warwick Wind Trials Project (WWTP) is converted into revenue in a net-present-value (NPV) framework for assessing commercial purchases of small wind systems. Variances in project variables are examined through NPV simulations using Monte Carlo analysis to capture permutations of small wind-project performance in the UK-with and without the UK FIT. Our research concludes that the proposed tariff amount of 30.5 p/kWh will not significantly boost the economic attractiveness of mildly selective (WWTP-based) sites in the UK. Furthermore, the fixed-tariff rate (£/kWh generated) could cause inefficiencies applied across uneven wind-resource distribution. The results of this study suggest further examination of policy related to micro-generation, in particular decentralised small wind projects.
