"Marking the official inauguration of London Array, the world's largest operational offshore wind power plant to date at an official event in Margate, Kent. Rated at 630 MW, Phase One of London Array generates enough energy to power around 500,000 British homes and displaces over 900,000 tonnes of CO2 a year -- equivalent to taking nearly 300,000 cars off the road each year. "
"Siemens and DONG Energy continue their successful cooperation in offshore wind. On July 19, 2012, the companies signed a framework agreement for the supply of a total of 300 wind turbines with a capacity of 1,800 megawatts (MW). The agreement is based on the new SWT-6.0-154 direct drive wind turbine that will be installed in wind power plants off the British coast between 2014 and 2017. The world's largest rotor blade measuring 75 meters in length equaling a total rotor diameter of 154 meter will be deployed.

"- High Concentration PhotoVoltaic Thermal system able to convert 80 percent of the collected solar energy
- System can deliver electricity, potable water and cool air in remote locations
- Design based on a low-cost, large dish-like concentrator and micro-channel cooled high performance photovoltaic chips suitable for mass-production
Today on Earth Day, scientists have announced a collaboration to develop an affordable photovoltaic system capable of concentrating solar radiation 2,000 times and converting 80 percent of the incoming radiation into useful energy. The system can also provide desalinated water and cool air in sunny, remote locations where they are often in short supply.

The prototype HCPVT system uses a large parabolic dish, made from a multitude of mirror facets, which are attached to a sun tracking system. The tracking system positions the dish at the best angle to capture the sun's rays, which then reflect off the mirrors onto several microchannel-liquid cooled receivers with triple junction photovoltaic chips -- each 1x1 centimeter chip can convert 50 watts, on average, over a typical eight hour day in a sunny region.
The entire receiver combines hundreds of chips and provides 25 kilowatts of electrical power. The photovoltaic chips are mounted on micro-structured layers that pipe liquid coolants within a few tens of micrometers off the chip to absorb the heat and draw it away 10 times more effective than with passive air cooling.
The coolant maintains the chips almost at the same temperature for a solar concentration of 2,000 times and can keep them at safe temperatures up to a solar concentration of 5,000 times.
The direct cooling solution with very small pumping power is inspired by the hierarchical branched blood supply system of the human body and has been already tested by IBM scientists in high performance computers, including Aquasar. An initial demonstrator of the multi-chip receiver was developed in a previous collaboration between IBM and the Egypt Nanotechnology Research Center.

"Bruno Michel, a research scientist at IBM Research - Zurich, explains his latest invention--a technique for concentrating solar radiation to create a much more effective system for harvesting energy from the sun. His hope is that this technique will prove to be so successful that we'll be able to use it to replace all fossil fuel and nuclear energy with solar. The work is being done in conjunction with the Egypt Nanotechnology Center: http://www.egnc.gov.eg
On Earth Day 2013 scientists announced a collaboration to develop an affordable photovoltaic system capable of concentrating, on average, the power of 2,000 suns, with an efficiency that can collect 80 percent of the incoming radiation and convert it to useful energy. The proposed system can be built anywhere sustainable energy, drinkable water and cool air are in short supply at a cost of three times lower than comparable systems."
"Emergency off the British Coast of Kent. Two ships collide and one crashes into one of Siemens' wind turbines of the offshore wind farm London Array. Five hundred people from forty organizations rehearse the emergency in connection with a wind turbine. For Siemens and its ambition of a "Zero Harm Culture" this training exercise is a welcome opportunity to put its health and safety skills to the test. See for yourself what it means to be prepared at all times."
