    European governments have agreed to increase the share of renewable energy in final energy consumption to 20% by 2020. A crucial question for policy makers is how to mobilise the additional capital investments in RE and which consumer expenditures are involved. The article describes policy options for reducing renewable energy technology (RET) project costs as well as consumer costs, based on research conducted in de Jager et al., 2011 and Rathmann et al., 2011. The results show that risk-sensitive RET policies are crucial for attracting sufficient RET investments until 2020 and achieving the targets cost-effectively. They not only reduce the RET financing costs, but also the project development costs and market gap. There are also other options that can significantly reduce the RET support costs, i.e. the adjustment of support levels to generation costs, phasing out subsidies for conventional energies, and the cost-optimisation of the supported RET portfolio, either th rough increased cooperation between member states or through changes in the supported technology mix. Overall, further improvement and coordination of existing policy frameworks seems more promising than drastic system changes, as the latter would create additional uncertainties and potentially negative effects on RET growth and project costs.

    This article evaluates the status of current RES deployment, policies and barriers in the EU-27 member states and compares it to the required to meet the 2020 targets. The evaluation relies strongly on the quantitative deployment status and policy effectiveness indicators. European RES deployment and policy has progressed strongly in recent years, but the growth here has been mainly driven by effective policies in a small or medium number of top runner countries. Across Europe, the highest average policy effectiveness over six years was reached for onshore wind (4.2%), biofuels (3.6%) and biomass electricity (2.7%), while in the heat sector, all technologies score below 2%. Comparing the recent progress to the required growth for meeting the 2020 target, it appears that some countries largely exceed the interim targets of the RES Directive 2009/28/EC. Despite this, Europe will need additional policy effort to reach the 2020 target. Critical success factors include imple menting effective and efficient policies that attract sufficient investments, reducing administrative and grid related barriers, especially in currently less advanced countries, upgrading the power grid infrastructure, dismantling financial barriers in the heat sector, realising sustainability standards for biomass, and lowering energy demand through increased energy efficiency efforts.
