Currently the green-energy industries in both Germany and Canada have a globally recognised leadership role. In order to stay ahead of the field, closer ties between researchers may be a good idea. Fraunhofer and the the University of British Columbia are now trying joint scientific projects for the energy changeover.
It is unclear whether Berlin's new airport will open in 2013, 2014 or ever, but among the potential ruins an interesting renewable energy project might prevail. Five project partners combine photovoltaics, a wind farm and hydrogen technology to an environmentally sensible mobility solution.
One of the major problems of using renewable energy is the storage issue. A Stuttgart-based company may have found a key to solving this by using the natural gas networks.
While renewable energy obviously is a good idea, sources like wind and sunshine have the downside of not flowing constantly 24/7. Furthermore, the time of day where, for example, the sun is shining, might not be the period with the highest demand - at least not in Europe, where aircondition isn't a matter of course as it is in other parts of the world. So, one of the major obstacles for the energy changeover is the problem of storage.
In response to the urgent renewable energy needs of modern society and ecological concerns, it is essential to develop novel inexpensive and environmentally friendly energy conversion and storage systems. Mesoscopic dye-sensitized solar cells (DSCs) have recently emerged as a credible alternative to solid-state p-n junction photovoltaic devices, primarily due to their potential to generate electricity on resource-abundant raw materials and energy-saving device processing. The famed carbon nanotubes significantly raise the efficiency.
While the light turns on and the TV starts at the push of a button, there lies a tremendous amount of effort behind a secure supply of power. Because of the demand fluctuations, specialists must calculate precisely how much power is needed and when. Weekends, for instance, when offices and stores are closed, require less energy than Mondays. And when it is gray and rainy outside, the lights get turned on earlier than on sunny days. More than anyone else, transmission grid operators have to know in time when electricity from renewable energies is being generated because they have to transport it across the country and partly market it by themselves.
The need for exponential growth in solar-energy production, as required by Europe’s 2020 climate targets and general energy policies, creates formidable technological challenges. A new European research program aims to address these requirements by improving the efficiency of solar cells, devising innovative harvesting techniques, reducing power-conversion losses, and enhancing energy-management strategies.
Conflicting signals from European governments have upset the PV market in 2011; even though the year ended on an optimistic note. Forecasts for 2012 indicate interesting developments.
Ever since the German government returned to the anti-nuclear energy policy of its predecessors, scientist, politicians and utility companies are trying to figure out ways of restructuring the infrastructure. In order to expedite this process, a new award for »intelligent energy« will be bestowed for interesting approaches.
Neither in phyics nor in chemistry 'electricity' has a state of aggregation but jointly the two disciplines can create something of that effect . This can minimize the effects of the time-variability of most renewable energy sources and, by better storage possibilities, ease the pressure on battery development.
