Considerations in Fuel Cell Voltage Monitoring
Knowing what's happening inside a fuel cell is a critical function, especially as fuel cells are continuing to be developed. One important aspect of this is to measure the voltage of each cell in a stack. Although this may sound trivial, it can be more complex and more expensive than it may at first appear due to high voltages, high channel counts, communication types, etc. There are a few products commercially available that are designed specifically for fuel cell voltage monitoring.
Wind energy: Why is project certification so important?
What can you do as an investor to protect your wind farm investment? What can you do as a wind farm owner to secure your wind power production? How can the trust of insurance companies for wind farm projects be improved? The solution is to find an independent inspection, testing and verification company that combines technical consultancy with project certification.

Solar Repowering
REPOWERING, in general, can be defined as the set of changes aimed at increasing the power and therefore also increase the energy yield. The convenience of the repowering is in the benefits of technological modernization, which provides solutions for higher power and performance as the technology matures.
Asia-Pacific Renewable Energy Policy Handbook
GlobalData's report "Asia-Pacific Renewable Energy Policy Handbook" presents an in-depth analysis of the renewable energy policies across the major renewable energy markets in Asia-Pacific. It details the key policy instruments adopted by the major Asia Pacific countries in order to promote the deployment of renewables. The report provides the current and future renewable energy targets and plans along with the present policy framework, giving a fair idea of overall growth potential of their renewable energy industry. The report also provides technology specific support policies and measures used in different countries.
Phoenix Role in Prospective "Hydrogen Economy" - 2010 Outlook
A succinct-analysis of the increasingly widely discussed alternative and renewable energy universe serves to bring the Phoenix "Hydrogen Economy" initiative (with its REPLACEMENT energy status) into its special perspective.
Renewable Lean - The Need for Lean in Renewable Energy Manufacturing
Using Lean to produce renewable energy products will keep costs low, make the investment of capital more efficient, provide product in the shortest possible lead time, and ensure the continued growth of the industry. Using Lean will drive cost out of the products/processes allowing more conversion to renewable energy for every dollar spent. Some renewable energy manufacturing companies are using some Lean tools, but much more can be done to reduce the waste in manufacturing these products.
AltEnergyMag Interview - Electrical Energy Services and Renewable Energy
We believe that renewable energy services play to the strengths that we have developed in offering electrical and communications services to the commercial, industrial and residential markets. These renewable energy services are a very natural and logical extension of our traditional offerings.

AltEnergyMag Interview - Bio-based Solar Cell Backsheets
With over two decades of engineering, marketing, sales and executive management experience in high technology, BioSolar, Inc. Chief Executive Officer Dr. David D. Lee founded the company in 2006. An electrical engineer, Lee recognized that historically, manufacturing costs have been one of the biggest barriers to driving down the cost per kilowatt of solar energy for consumers. In response, BioSolar was the first company to introduce a new dimension of cost reduction by replacing petroleum-based plastic solar cell components with durable bio-based components derived from renewable plant sources.
Wind Powers 2.4 Million More Homes in 2009
New wind-turbine generation capacity grew by a record 10,000 megawatts in 2009, picking up the pace from 8,400 megawatts added in 2008, the American Wind Energy Association said Tuesday. Put another way, the 10,000 megawatts of new wind generation added in 2009 will provide enough power for 2.4 million U.S. homes. Texas continues to lead America in installed wind power, with 9,410 megawatts, followed by 3,670 megawatts for Iowa and 2,794 megawatts for California. Together, wind and natural gas make up about 80% of the new generation capacity added in the country in 2009.
Solar Powered Aircraft to Circle the Globe
When Bertrand Piccard came up with his audacious plan to fly around the world in an aircraft powered only by the sun, he found that airplane manufacturers were skeptical such a plane could be built. So who built the first model of " Solar Impulse ," Piccard's $72-million solar-powered craft? A company that makes ships. And now the airplane is built. The first flight was achieved on the third of December and in the spring and summer this year, we're going to make the high-altitude flights and the cycle of [flying] one day, one night and one day. This little airplane is not a Piper or Cessna with a couple of solar cells. It's a really high-tech carbon fiber airplane which is 200 feet in wingspan. It weighs 1.6 tons. The plane will travel very slowly. Otherwise it would take too much energy. The average speed will be 40 knots, roughly 55 miles per hour. The entire budget is 100 million U.S. dollars, coming from private sponsors.
Detroit Auto Show Unveils Lots of Hybrids, Concepts and News
Toyota's FT-CH Hybrid Concept and Plans for a Prius Family --- Ford's New Plug-in Focus --- General Motors' Volt Roll out and Upcoming Plug-in Converj --- Honda's 2011 CR-Z Hybrid Debut --- PLUS --- Ford has announced that it plans to invest $450 million in Michigan for production of electric, hybrid and plug-in hybrid vehicles . The company expects to create up to 1,000 new jobs through its electrification efforts, in part by moving battery pack production to Michigan from current facilities in Mexico.
43 billion dollar North Sea Green Energy Plan
Nine European countries have teamed up to plan a 30-billion-euro (43-billion-dollar) sustainable energy project in the North Sea as part of efforts to address climate change and expand renewable energy, officials said Wednesday. The plan is to connect up the alternative energy projects of the nine nations to create Europe's first renewable electricity grid through a 6,000-kilometer network. The network would link the wind turbines off from the northern coast of Scotland with Germany's solar power industry and include the wave power plants dotted along the Danish and Belgian coasts and hydroelectric dams in Norway. It is expected to take a decade to complete the building work for the network, with the nine nations to unveil a feasibility plan later this year.
