2 The elements of change in the energy paradigm The serious drawbacks of the existing energy supply schemeImply a change whose main vector is:Reduce the carbon content of the primary energy sourcesEnergy saving and efficiency increaseLess fossil fuelsMore renewablesMore (at least keep) nuclear (Fukushima accident?, Gen IV?)Possible clean use of coal (CO2 capture and sequestration)Fusion (not available in the short term)None of these alternatives are free of problems. To implement them, a big effort in technology development and political support is necessary.
4 Renewables in the Spain energy supply 11,3% in Primary Energy13,2 % in Final Energy35 % in Electricity5 % biofuelsCO2 emissions by unit of electricity produced
5 Solar energy is plentiful but diffuse The solar resourceIn good conditions, the daily averaged incoming solar flux is around 220 – 250 W / m2 which, integrated, gives a yearly primary energy of around 2000 – 2200 kWh / m2. This is equivalent to a “rain” of about 20 cm of oil per annum and m2. 1,2 barrel/(year x m2)Solar energy is plentiful but diffuse
6 CSP prospects in Spain, 2009With Spain at the Epicenter, Global Concentrated Solar Power Industry to Reach 25 GW by 2020Cambridge, Massachusetts, 28 April Led by development in Spain and potential in the US, concentrated solar power markets are entering a new growth phase, amidst a tumultuous global economic landscape. The CSP industry is scaling rapidly with 1.2 GW under construction as of April 2009 and another 13.9 GW announced globally through 2014, according to a new study from Emerging Energy Research analyzing global CSP markets and strategies.Spain is the epicenter of CSP development with 22 projects for 1,037 MW under construction, all of which are projected to come online by the end of Despite only 75 MW of CSP under construction, the US continues to offer significant opportunity for CSP, with 8.5 GW in the pipeline and scheduled for installation by Attracted to promised lower costs, US utilities have turned to CSP -- through both Power Purchase Agreements and direct ownership -- to meet their Renewable Portfolio Standard mandates.
