This scientific study combines analysis of up-to-date international manufacturing and market implementation data throughout 2007 with subsequent strategic and political developments up to September 2008.
Preliminary findings show:
- an increase in the yearly growth rate of solar photovoltaic production, averaging 40% over five years and then peaking at 60% in 2007;
- a €5.7 billion turnover in Germany in 2007 with in excess of 100,000 houses installing solar panels;
- world electricity production with PV systems is ca 10 Billion KWh, of which half comes from the EU. Solar energy still accounts for only 0.2% of total electricity consumption in Europe. Yet, the net effect is 4 million fewer tonnes of CO2 being released;
- incentive schemes and technical advances are having a positive downward impact on photovoltaic costs. Market value is estimated to reach €40 billion by 2010 with lower prices for consumers.
How does solar power work?
Photovoltaic solar energy is one of 14 different energy technologies that the Joint Research Centre is currently assessing within the context of the Strategic Energy Technology Plan, which is a key input to Europe's current energy policy. Solar energy works by generating electricity using semiconductor devices known as solar cells. A number of solar cells form a solar "Module" or "Panel", which can then be combined to solar systems, ranging from a few Watts of electricity output to multi Megawatt power stations. Recent advances such as thin film technologies are becoming increasingly commercial. This process allows an entire module to be processed in a single step.
A bright future for solar
The photovoltaic growth scenario for Europe based on 2001 to 2007 data, an analysis of European policies and assessment of current investments predicts that more than 15TWh of electricity will be generated in 2010. This equates to 0.5% of the EU 27 total net production of electricity in 2006 or the same as Slovenia's total electricity consumption.
Projections are that by 2012 China will account for 27% of worldwide solar cell production capacity (approximately 42.8 GW), followed by Europe with 23%, Japan with 17% and Taiwan with 14%.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
