The American Wind Energy Association (AWEA) with support from the US Energy Department and National Renewable Energy Laboratory, has developed a set of recommended practices for using existing standards to plan, design, construct and operate offshore wind facilities in compliance with federal and state regulations. The recommended practices drawn up by AWEA’s Standards Development Board cite four levels of existing standards: international, American National Standards, classification society such as DNV, Germanischer Lloyd and The American Bureau of Shipping standards, and commercial standards and guidelines, These standards address five critical areas: structural reliability; manufacturing, qualification testing, installation, and construction; safety of equipment; operation and inspection, and decommissioning. The 63-page Recommended Practices for Design, Deployment, and Operation of Offshore Wind Turbines in the United States was unveiled at AWEA’s offshore windpower conference here.
AltEnergyMag had a residential PV system installed and is monitoring the process as well as the performance. This is part 2 of a series of articles we will publish along the way in order to demonstrate and explain a real world project for our readers to follow and learn from.
Europe's electricity demand is increasing. In the context of Europe's decarbonisation goals, this power will have to come from more variable Renewable Energy Sources. As European policymakers consider their options for invesments in new and more efficient grid infrastructure, they should take into account the benefits that PV is already producing and, more importantly, plan for the greater benefits it is capable of producing in the future.
The dataset is designed to provide realistic energy production profiles based on wind variability, both for the existing fleet as well as large expansions thereof. One of the main concerns with wind energy is that it is variable, with energy produced only when and where the wind blows.
Compared to other mechanisms that convert chemical energy into electricity, the fuel cell, specifically the solid oxide or ceramic fuel cell, is the most efficient.
With the solar energy industry reporting that the second quarter of 2012 was the second largest quarter in history, there was "tremendous enthusiasm and vitality running through the entire solar industry value chain," said Rhone Resch, president and CEO of SEIA.
TeamSustain designed a 65kW battery-based PV system for Spice Village. The system was designed to support the full load of the resort after implementing the energy efficiency measures identified in the energy audit. With the new PV system, the resort will generate enough solar electricity to meet 100% of its power needs.
Green Banks are essentially clean energy finance banks formed at the federal or state level that operate as public-private financing institutions with the power to raise capital to support clean energy projects through loans and loan guarantees.
There are hundreds of thousands of contaminated sites across the country, and every solar or wind project that rises from an industrial wasteland is one that won't be built on unspoiled land, and it is unlikely that there would be public opposition to renewable energy projects on blighted land.
In just three months this year enough solar PV was installed nationwide to power 150,000 homes, while no new coal or nuclear plants came on line.
Interior Secretary Ken Salazar on Tuesday authorized what he described as potentially the largest wind energy project in the United States, if not the world: A Wyoming wind farm with up to 1,000 turbines that would provide electricity to some 1 million homes. Roadwork and groundwork could begin next year for the Chokecherry and Sierra Madre Wind Energy Project. After that, turbines could go up over a three-year period within an area covering 350 square miles of the hilly sagebrush country south of Rawlins in south-central Wyoming. Most of that area is among the 245 million acres nationwide overseen by the U.S. Bureau of Land Management — hence Salazar's role. Salazar highlighted the project as an example of President Barack Obama's "all of the above" strategy for renewable energy development and fossil fuel extraction on BLM and other public lands.
The Commerce Department issued its final ruling Wednesday in a long-simmering trade dispute with China, imposing tariffs ranging from about 34 percent to nearly 47 percent on solar panels imported from the country. For most of the Chinese manufacturers, the penalties are somewhat higher than those announced by the Obama administration earlier this year, when the government determined that Chinese companies were benefiting from unfair government subsidies and were selling their products below the cost of production, a practice known as dumping, on the American market. For the biggest panel maker, Suntech, the duties are significantly higher, moving to almost 47 percent from about 33 percent. The trade case stemmed from a legal filing nearly a year ago by a coalition of manufacturers, led by SolarWorld, a German company with considerable manufacturing in the United States. The coalition contended that Chinese companies, which dominate global sales with a two-thirds market share, were competing unfairly in the American market.
Solar panel installer SolarCity Corp filed with U.S. regulators to raise up to $201 million in an initial public offering that could help rekindle investor appetite for cleantech stocks. Shares of solar panel manufacturers have logged terrible performances in the last two years as plunging panel prices erased profits. But those lower prices have spurred demand for solar systems in the United States, helping companies like San Mateo, California-based SolarCity. SolarCity has expanded rapidly thanks to a business model that allows residential customers to lease solar panels for their roofs. Rather than paying the large upfront costs required for a solar installation, customers pay a monthly fee. Companies including Google Inc (GOOG.O) and U.S. Bancorp (USB.N) have provided funds to finance SolarCity’s projects. Those investors are able to collect a 30 percent federal tax credit for solar energy systems. Two of those funds are being audited by the Internal Revenue Service, SolarCity disclosed in its filing on Friday.
Vestas Wind Systems A/S (VWS) and Siemens AG (SIE), the biggest manufacturers of offshore wind turbines, and 42 other companies are participating in an initiative to lower power-generating costs for the technology and promote investments that may reach as much as $630 billion by 2035. The alliance, called Norstec, will meet today for the first time in London, the U.K. Department of Energy and Climate Change said in an e-mailed statement. The number of members has more than doubled since U.K. Prime Minister David Cameron announced the group’s formation in April. The group is seeking to drive development of offshore wind farms, an industry with the potential to employ as many as 185,000 people in the U.K. by 2020 and spur the laying of 8,000 kilometers (5,000 miles) of high voltage transmission cables in Europe’s northern waters by 2022, Norstec said today in a statement e-mailed by DECC.
Earlier this month, Denmark announced that it had already achieved its 2020 goal for solar energy production. The country previously publicized its national goal to produce 200 megawatts of energy from solar power by the end of this decade. Now, it seems that rapidly growing demand for clean energy and a solar-friendly government has allowed this European country to exceed that goal eight years before the target. Danish experts now predict that if this growth continues, 2020 levels of solar energy production will be 100 times what was first expected. Have you ever been to Denmark? Few would call it a sunshine-rich country. In fact, it’s probably better known for its gray, cold winters. So what has allowed Denmark’s solar industry to expand so rapidly?
