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 - 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.

The Next Generation of PV System Ownership: Moving from Passive Monitoring to Active Management

This article reviews the recent history of PV monitoring; the shift from single-meter systems to module-level control using highly reliable electronics, and future direction of the industry towards active system management from utility-scale solar farms down to the residential PV system.

Importing Clean Energy from Mexico

The alternative energy money-men dreaming of clean energy from Mexico see several factors that make the country perfect for power production aimed at the Southwest U.S. Baja California and other parts of Mexico have gusty winds similar to those found in the world's best wind farm areas. Much of Mexico also boasts the same excellent solar footprint as California, Nevada and Arizona with bright, clear weather the vast majority of the time. In terms of total energy potential, the hills and fields of Mexico could easily supply thousands of megawatts to the U.S. without breaking a sweat. Energy developers to the North see huge potential not only in the winds whipping across Mexico but also in the hot sun that bakes the land. Perhaps most important, they see an easier, quicker and cheaper route to getting big energy projects built compared to the multiple levels of permitting processes required north of the border.

Rope Workers Benefit from Alternative Energy Boom

Suspended by ropes from the top of a giant wind turbine, two men slowly descended down a long, silvery blade. Then they got to work, and from 150 feet above the ground, the hum of a sander filled the air. For Matt Touchette and Sequoia Haughey, it was another day at the office. Rope specialists like Mr. Touchette and Mr. Haughey have long filled a range of niche jobs, like inspecting big dams, cleaning Mount Rushmore and repairing offshore oil platforms. But as wind farms have sprouted across the nation, rope companies have quickly expanded into a new line of work - fixing turbines so they last longer in the elements. It's a dream job for rock-climbing types. Photograph by Jigar Mehta/The New York Times

Solar on a Stick: Bringing Solar to the Sun

One solar PV innovation has largely flown under the radar: pole mounted solar electric panels. That is, mounting solar PV panels on a steel pole anchored in cement, fully capable of adjusting to daily and seasonal sun positions.
