Environmental and Life Cycle No-one will deny that the environment is an important factor to consider when doing anything these days. Engineers are the ones largely coming up with the solutions.

Last week, the European Wind Energy Association (EWEA) held their 2009 offshore event in Stockholm, where 4,750 attendees (up from about 2,000 in Berlin two years ago) congregated to celebrate what is now clearly emerging: a boom in offshore wind in Europe over the next decade. EWEA projects 50 gigawatts of offshore wind installed by 2020. With 20 gigawatts of projected installation, the United Kingdom is making a play to steal (or at least share) German leadership in offshore wind manufacturing and deployment. So, the offshore wind industry seems to be really taking off in Europe. Here in the U.S., as is the case with so many things on the energy front, we're years behind.

Konarka Technologies Inc and SKYShades entered into a partnership last year to jointly develop the Powerbrella, an umbrella that converts sunlight into electricity to charge laptops, mobile phones, iPods and other portable devices. The initial focus for the al fresco umbrella is coffee shops, hotels and resorts.

SCA is a global consumer goods and paper company that develops and produces personal care products, tissue, packaging solutions, publication papers and solid-wood products. It has sales in 90 countries and many well-known brands, including Tena and Tork. SCA has been a pioneer in prioritizing environmental and sustainability issues and published its first environmental report in 1998. In 2008 SCA established a new carbon-dioxide target of a 20% reduction in emissions from fossil fuels from 2005 through 2020. It has also undertaken to reduce its water consumption by 15% from 2005 through 2010 and to reduce the organic content in its wastewater by 30%.

Think-tank behind "Danish" Wind Study Tied to Polluter Funding. The Institute for Energy Research (IER), a polluter front-group, has released a study from CEPOS, that claims to show that wind power is overstated.

More than 31,000 MW of new wind capacity was added worldwide in 2008, a record that can be described as an absolute milestone in the modern history of wind power development. Fortunately that build up -- and the dip in overall wind market demand that has followed the financial constraints -- did not take place at the expense of wind industry development nor technology innovation.

“Recycling and consumer waste are still managed with 1950s technology,” said Valerie Thomas, Anderson Interface Associate Professor at Georgia Tech’s School of Industrial and Systems Engineering. “Of course it can’t keep up. The flow of products out of the household needs to be managed with at least as much intelligence as the flow of products into the household. It’s sort of obvious.”

Although the current slide in overall wind market demand means 2009 figures are unlikely to match recent booms, the dip has not come at the expense of wind technology innovation.

The Benthic Rover makes its way across the deep seafloor during a trial run in 2007. The "brains" of the vehicle are protected by a spherical titanium pressure housing. The orange and yellow objects are made of incompressible foam, whose buoyancy makes the Rover light enough underwater so that it won't sink into the soft deep-sea mud. Image: © 2007 MBARI

One wind turbine , depending on its size, is comprised of 10 to 25 tons of iron castings that range in weight from less than 100 lb to as much as 80,000 lb, states the American Wind Energy Association (AWEA). Typical wind turbine hubs, for instance, can weigh in at 36,000 lb and measure 15 ft in diameter.

The levelized electricity cost of concentrating solar power plants depends on both the available solar resource and development costs of investment, financing and operation. Plants under the same price and financing conditions in the south western United States or upper Egypt, will have a levelized electricity cost 20% to 30% lower than in southern Spain or the north African coast. This is because the amount of energy from direct sunlight is up to 30% higher (2600–2800 kWh/m2 a year compared with 2000–2100 kWh/m2 a year). The solar resource is even lower in France, Italy and Portugal, while the best solar resource in the world is in the deserts of South Africa and Chile, where direct sunlight provides almost 3000 kWh/m2 a year.

Larger Output Reduces Total System Cost for End Users. Mitsubishi Electric Corporation announced the launch of ten new models of photovoltaic (PV) modules.
The new lineup comprises modules with outputs of 210, 220, 225, 230 and 235 watts. Shipments will begin on January 15, 2010. The new high-output modules use lead-free solder and incorporate PV cells with four bus bars.

Space is not a fun place to get a stomach bug. To ensure drinking water is adequately disinfected, University of Utah chemists developed a two-minute water quality monitoring method that just started six months of tests aboard the International Space Station.
"Now they bring water back on the space shuttle and analyze it on the ground. The problem is there is a big delay. You'd like to be able to maintain iodine or silver [disinfectant] levels in real time with an onboard monitor," says Marc Porter, a University of Utah professor of chemistry and chemical engineering. |

With increasing depth , geothermal energy offers an almost inexhaustible potential for renewable energy. The drilling costs however, rise exponentially with depth in the case of conventional rotary drilling. A thermal drilling method, which will allow for reaching greater drilling depths in a more efficient and more cost-effective way, is currently being developed at the ETH Zuric |
