Chapter 2: The Future Prospect of PV and CSP Solar Technologies
Solar Photovoltaic (PV) and Concentrated Solar Power (CSP) represent promising options for electricity production and could significantly contribute to lowering CO2 emissions and dependence from fossil fuels. PV and CSP are among nine ‘technological paths’1 which the EU and its Member States plan to implement to collectively promote sustainable energy use (EC, 2009). EU commitment to solar technologies has been strong in the last decade. In 2007, solar PV and CSP represented around 27 percent of public Research and Development (R & D) investments in non-nuclear low carbon technologies in the EU, reaching around 275 million USD.2 Collectively, EU public R & D investment in 2007 was higher than public support in the USA (EC, 2009 and IEA, 2011). The highest contributions for PV came from Germany and France, while Italy and Spain led the investments in CSP. The Green Fund included in the economic stimulus packages of 2010 for the EU Member States and Norway totalled 54.2 billion USD, of which around 3.5 were devoted to low carbon renewable energy (Robins et al., 2009 and HSBC, 2009). In addition, a number of countries have implemented feed-intariffs and other forms of support to small and large scale solar technology deployment as well as targeted tax breaks (IEA, 2012).
