The regulatory requirement to prove collision-friendly foundation design need not be a cost-intensive mandatory additional measure, but may be an opportunity that significantly improves reliability and safety. It would increase the lifespan of the primary structure of the wind turbine, preventing subsequent time- and cost-intensive repairs.
The hydrogen fuel cell barge bypasses the need for electrical infrastructure. The barge also has the capability of being moved from berth to berth as needed and to anchorage points to power vessels that are waiting for berths.
Solar Energy USA had the privilege of engaging in a solar power question & answer session with Tim Echols, one of the five Georgia Public Service Commissioners responsible for regulating large monopolistic entities in Georgia. This article showcases some important points about power generation and power delivery as they relate to Georgia residents.
Energy free residences are not only practical but they are the dwellings of the future. Let's hope that home builders start thinking zero net energy as they design upcoming housing subdivisions.
California's Alternative and Renewable Fuel and Vehicle Technology Program, for example, is more than half way through implementing its target of supporting installation of more than 6200 charging stations, and Tesla, Nissan, and Rabobank/SolarCity have been developing their own charging networks in California.
Solar PV has been one of the fastest growing energy sources in the US over the past six years, with a compound annual growth rate of over 50% since 2007.
19,000 visitors visited to learn about the latest technology innovations, financing models, business best practices and policy and incentive programs that are contributing to the growth of the U.S. solar industry. Products from nearly 600 exhibitors from 22 countries were on display on all three levels of Moscone West, representing the entire system of solar technology and showcasing advances in solar cell and module technology, balance of system components, solar heating and cooling and energy storage. AltEnergyMag.com has once again partnered with Intersolar to bring all the industry news and exciting new products to our eMagazine and help our readers make sense of this key tradeshow. Here we have compiled a list of some product releases from this years show. Check out our special Intersolar 2013 Newspage for Exhibitor news.
The solar energy industry is in high gear and at Solar Power International 201 3 (SPI ’13), October 21-24, McCormick Place, Chicago, Illinois, participants can plug into the technologies, personal connections and professional insights that give rise to new business and learning opportunities. Widely regarded as the can’t-miss industry event of the year, SPI draws over 15,000 professionals in solar energy and related fields, from 75+ countries. One in six attendees comes to this global event from outside the United States. Attendees include manufacturers, installers and contractors, distributors, engineering firms, utilities, government representatives and policy makers, investors and financiers, architects, builders and developers—anyone who needs to stay on top of the latest developments in solar energy. Nearly 700 companies representing the entire solar industry spectrum exhibit on 300,000 net square feet of space. Exhibits highlight the latest in PV cells and modules; balance of systems; material and equipment suppliers; distributors; integrators; installers and solar service providers; thermal solar technologies; concentrating solar power (CSP) and solar thermal electric and concentrating PV (CPV); publications; and an additional array of products and services. SPI presents a full range of opportunities to make connections in Chicago and throughout the solar energy industry. Build your network face to face in SPI’s general sessions, conference sessions, receptions and training workshops—or as you explore the dynamic exhibit floor. SPI is presented by the Solar Energy Industries Association (SEIA) and Solar Electric Power Association (SEPA). Unlike other solar conferences, all proceeds support the expansion of the U.S. solar energy market through SEIA's and SEPA's year-round research and education activities, as well as SEIA's advocacy, research and communications efforts. Join SEIA or SEPA by October 18, 2013, to enjoy a membership discount on Solar Power International 2013 registration as well as many member benefits year round. For details on association membership, visit www.seia.org or www.solarelectricpower.org . For networking, ideas, making deals and discovering opportunities, solar energy professionals head to one event: Solar Power International 2013. Register today!
The Solar Thermal System at Oxford Gardens
CSI data shows that 4,000 new homes were built with solar in California last year. SunPower observes that that's 10 times the number built in 2006, when the housing construction market was booming.
So far 2013 has been an exciting year for fuel cell buses, with a host of news reports from the U.S. and abroad.
If oil and gas is a profoundly dynamic phenomenon, then so too must be environmental risk and conflicts over natural resources—and we are not getting the full picture from the mainstream media, according to Michael T. Klare, professor of peace and world security studies at Hampshire College

Marine energy technology leader Minesto develops world's first simulator for anchored flying underwater vehicles
Nordic marine energy technology leader Minesto has developed a simulator to aid the development of its Deep Green marine power plant. The simulator has been developed in-house by Minesto’s own research and development department, and is in essence based on two existing open source programs: one for commercial flight simulation and one for marine vehicle simulation. The end result is an analysis and simulation tool called HAMoS, Hydrodynamic Analysis and Motion Simulation, believed to be the first in the world to simulate the movements of a flying tethered underwater vehicle. It will be used to predict how Minesto’s marine power plant, Deep Green, moves subsea in various ocean environments and depending on the plant’s design. Minesto’s research, development and testing staff can change a number of variables in the power plant’s design to simulate and optimize its performance. The simulator can be used to predict Deep Green’s behaviour and power performance in different real-life site conditions (i.e. the strength and direction of the currents). Deep Green resembles a sweeping underwater kite, comprised of a wing and a turbine, which is secured to the seabed with a tether and moves with high speed in an 8-shaped path in the tidal or ocean current. Deep Green produces 100% renewable tidal energy.
Outlining a new climate change plan on a warm day in Washington, President Obama said Tuesday his State Department should not sign off on the Keystone XL oil pipeline if it increases greenhouse gas emissions. "The national interest will be served only if the project does not significantly exacerbate the problem of carbon pollution," Obama said in a speech at Georgetown University. Keystone is not part of the climate change plan that Obama said includes new rules to restrict "the relentless dumping" of carbon pollution from power plants, as well as the promotion of renewable energy sources and new energy-efficiency standards. Warning that climate change threatens future generations, Obama told his college audience that "the question is not whether we need to act" because "the overwhelming judgement of science ... has put all that to rest." The question is whether the nation has "the courage to act before it is too late," the president said. Almost all of the president's plan involves executive actions that do not require congressional approval. Obama would have a difficult time getting climate change legislation through Congress, given a U.S. House run by Republicans and a Senate in which the GOP has enough members to mount effective filibusters. Republicans and members of the energy industry criticized Obama's climate change plan, saying it will lead to higher utility bills and less development of reliable energy.
