Renewable electricity development has taken different paths across countries, underpinned by different policy frameworks. Although there has been a convergence to two main mechanisms, the feed-in tariff (FIT) and the renewable portfolio standard (RPS), much debate remains focused on the effectiveness of each for meeting multiple objectives, especially energy security, CO2 reduction and economic development. Although most countries share these objectives, their choice of policy varies, explained largely by national context. Denmark, Germany and the United Kingdom stand out as lead countries based on their experiences with the FIT and RPS and provide important lessons for other nations. The evidence from these three, as examined in this paper, suggests that policy design and commitment are key factors for success. Denmark and Germany have 10 years of experience with FITs and are world leaders in the field of renewable energy (RE) development. They are closest to meeting their RE targets and have been able to achieve several other objectives, especially industrial development and job creation, and in the case of Germany, CO2 emission reductions. Although other factors have been important in determining policy choice and implementation in these countries, the particular design features of the FIT allow it to address the needs of the sector.
