|A sunny future|
It is predicted that in a few years, the CSP market will grow from two to four gigawatts per year. To meet the on-going demand for energy, it is crucial to continually enhance the longevity of the CSP plant. The facts speak for themselves - solar energy is a huge and important trend.
|CSP industry - adapt or else|
If you want to have an accurate description of the CSP industry worldwide today, first you must forget everything that you might have read about it over the past few months. The CSP industry is going global in an unprecedented rate and there is no way to understand it by confining its development it to one market only. Make no mistake, despite the difficult times, the industry will persevere through the challenging times aheadâŠ but the companies that do not adapt to its changing nature will not.
|Lebrija 1: international solar thermal reference|
The Lebrija 1 solar thermal power plant, located in Seville and with a capacity of 50 megawatts (MW) and based on parabolic trough technology, has been developed by Siemens and Valoriza Energy (now called Sacyr Industrial) as a joint venture. It includes a solar field consisting of over 412,000 square meters of mirrors (equal to the area occupied by 54 football fields), all set in 6048 parabolas, each with 28 individual mirrors. If all the parabolas are placed in line, they would cover a distance of 72 kilometers.
|Wind in emerging markets: Poland, Romania and Bulgaria|
Poland and Romania are the leading lights of the emerging markets in the EU, in terms of wind installations. In 2011, according to EWEA fi gures from âWind in Power, 2011 European Statisticsâ, Romania installed 520MW of wind capacity, followed by Poland at 436MW. Both remain amongst the 10 biggest EU wind energy markets for the second year running, with Germany (2,100MW installed in 2011), the UK (1,300MW) Spain (1,050MW), Italy (950MW), France (830MW) and Sweden (763MW) leading the pack in 2011. Poland had installed 1,616MW in total by last year, while Romania had 982MW installed. Bulgaria is not too far behind with a total of around 612MW installed by 2011.

|Emerging wind markets: The sector will continue to grow the coming years|
Miguel Pérez de Lema
The global wind energy market continues to expand. The forecasts published in the latest Global Wind Report, prepared by Global Energy Council (GWEC) confirm growth. But we are probably facing the end of the big bang wind. China will not doubling their capacity every year, Europe will grow moderately by the effect of the credit crisis, and the biggest uncertainty is the future of the U.S. Production Tax Credit and Its Impact on the USA in 2013. The international market looking maintain the high rates of growth in new countries, as Turkey, South Africa, India, Brazil, or Mexico.
|Using simulation to optimize wind turbine design|
The increase of wind turbine power capacities from 20kW in the 1980s to 7.5MW today would not have been possible without the use of system-level simulation models. Without these models, subsystem integration issues cannot be detected and system performance cannot be measured until prototypes are built. Experts across mechanical, hydraulic, electronic, and controls departments are not only using simulation individually but also combining their models to perform system-level testing to optimize the turbine design. For complex, mechatronic systems like wind turbines, Model-Based Design has been shown to reduce product development times by 50% or more.
|PV Recycling â WEEE obligations and solutions|
When the amended directive of the European Parliament and of the council on waste electrical and electronic equipment (WEEE directive) is also becoming binding for all manufacturers and importers of solar and PV modules, the producers will require support in implementing such requirements.
|Solar power at the crossroads|
Solar photovoltaic (PV) electricity is at a crossroads. The technology continued its remarkable growth trend in 2011, even in the midst of financial and economic crisis and even as the PV industry was enduring a period of consolidation. But the rapid growth rate that PV markets have shown over the past decade cannot last forever, and the industry has entered a period of uncertainty in the short term. Over the medium and long terms, however, the prospects for continued robust growth are good. The results of 2011 â and indeed the outlook for the next several years â show that under the right policy conditions PV can continue its progress towards competitiveness in key electricity markets and be a mainstream energy source.
|CENER experience testing CPV modules|
A key concept when deciding the investment in a determined Photovoltaic (PV) product is to know if it passed tests enough to ensure its good performance, safety and durability characteristics. The latest technology appeared in the market is the CPV (Concentrating Photovoltaics). The special idiosyncrasy of those PV modules, with very different types of cells, receivers and assemblies, makes it difficult to establish common rule to test all of them. At this time, first edition of IEC- 62108 standard, issued on December 2007 is in place, and next revision Ed.2 is expected to reach final draft stage by 2013. The content of this paper is describing specificities of the IEC- 62108 standard and CENERÂŽs experience on testing it.
|Bioenergy in Europe|
Renewable energy provided 12,4 % of the total energy use in Europe in 2010 and bioenergy accounted for 68,2 % of the renewables. According to EurObserver, more than 500.000 people were directly or indirectly employed in the bioenergy industry.
