This technology seems to me to be much more beneficial on a local scale, what if every home had its own battery, then home power generation becomes economically more viable for everyone. If you could show that a system like this could pay for itself in say 5 years then every home would want one. Plus for this to be implemented on a large scale requires massive investment that could be decades away. Share the technology and lets get it in homes by next year. Great ted talk. Jon Senior 0 Reply 1 hour ago: I agree 100%. Localised energy production would also make energy consumers more conscious of their consumption and encourage efforts to reduce it. We can invent and invent all we want, but the fast solution to allowing renewable energies to take centre stage is to reduce the base energy draw. With lower baseline consumption, smaller "always on" generators are required to keep the grid operational. Town and house-l

General Motors Corp., along with a consortium of more than 30 utilities and a non-profit electric industry research group, has struck a deal to forestall potential problems when the company introduces its new electric vehicle to the nation's showrooms. An EPRI official also emphasized the grid aspects of the collaboration. Said Arshad Mansoor, the organization's vice president of power delivery: "Seemless integration of [plug-in hybrid electric vehicles] into the electric grid will require close collaboration between the automobile and electric sectors." The statements from EPRI and the car company also address safe and convenient vehicle charging, public education and other public policies, including codes and standards. Among the utility participants in the collaboration are Consolidated Edison of New York, Duke Energy, First Energy Corp., Pacific Gas & Electric Co. and Southern California Edison Co. Others are listed as part of the EPRI statement. The research organization last year released a report along with the Natural Resources Defense Council that concluded plug-in hybrids had the potential to lower greenhouse gas emissions. GM, meanwhile, emphasized the cost benefit of the new vehicles, saying consumers could find that the per-mile expense of an electric vehicle would be about one-fifth that of a gas-powered car.

The U.S. Department of Energy's National Renewable Energy Laboratory (NREL) and A123Systems have teamed up to support the battery-maker's effort to develop safe, less expensive, more powerful, and longer lasting batteries for hybrid-electric vehicles. The Laboratory and the battery-maker have signed a three-year, Cooperative Research and Development Agreement to examine and develop new techniques to improve thermal management in advanced transportation batteries. "We're pleased to be working with A123Systems on thermal management of their advanced nanophosphate-based lithium ion batteries," NREL Principal Engineer Ahmad Pesaran said. "Batteries with improved thermal behavior are critical for widespread acceptance of affordable hybrid-electric vehicles that consume less fuel and reduced harmful emissions." Hybrid electric vehicles get as much as double the fuel economy of comparable cars. Plug-in hybrids will be even more gasoline-stingy with potential of displacing significant amount of gasoline with electricity for road transportation. To achieve these goals, affordable, high-performance, safe, and long-lasting batteries need to be produced in large quantities. Propulsion batteries - batteries that power an electric motor to assist moving a car - are key components of hybrid-electric vehicles, and will be more important in the plug-in hybrid and extended range electric cars of the future. By better understanding the thermal behavior of advanced batteries, NREL researchers will help A123Systems engineers design improved thermal management systems and to optimize the design of the battery cell and develop a battery pack that's lighter, cheaper and more durable.

A new approach to storing electrical energy can store more energy than gasoline in the same volume, and could help extend the range of electric vehicles. But some experts say other approaches are more practical. The biggest technological hurdle facing electric vehicles is their range. Even the best rechargeable batteries cannot match the density of energy stored in a fuel tank. Combining electric power with a combustion engine to make a hybrid electric vehicle sidesteps that problem. But a new take on electrical power storage that is part battery, part chemical fuel cell could ditch gasoline for good.The new design stores energy more densely than petrol, and was conceived by Stuart Licht of the University of Massachusetts, Boston, and colleagues. Batteries produce electricity from a closed chemical system that is eventually exhausted. Fuel cells use a constant supply of fuel, so they are continually topped up. Licht's cell has features of each. Its negative electrode, or anode, is made from vanadium boride, which serves double-duty as a fuel too. But unlike the flowing fuel of a fuel cell, the material is held internally, like the anode material of a battery. The vanadium boride reacts with a constant stream of oxygen, as in a fuel cell, provided by the positive electrode, or cathode. This brings in a supply of air from outside.

August 12, 2008 What will the electric carInnovation-At-Big-Companies Dec-07 ownership experience be like? NissanNissan Motors has given us a glimpse of what early adopters are letting themselves in for - rather than bundling expensive, consumable battery packs into the price of the car, Nissan plans to sell its 2010 mass-market battery-electric car for around the same price as a standard petrol car, and lease the battery pack to the buyer on a monthly fee. And the battery lease plus electricity charges should still end up cheaper than a petrol bill. Don't worry, it won't look anything like the test vehicle pictured! In an encouraging auto industry trend, more and more major players are committing to launching hybrid, hydrogenhttp://en.wikipedia.org/wiki/Hydrogen and battery-electric carsElectric car in the next few years. Nissan is the latest to outline its plans, which will include a production-model lithium-ion plug-in electric car by 2010. There's also a clever high-tech hybrid on the way, and Nissan has also announced a cheaper way of building a high-power density hydrogen fuelGM-Coskata-Alternative-Fuels cell stack. But it's the imminent battery-electric vehicle (BEV) that offers the most immediate chance for car buyers to get away from gas stationshttp://en.wikipedia.org/wiki/Filling_station and look into green motoring. And while no details have yet been officially released about range, charging time, body shape or power, Nissan has clarified that its first mass-market BEV will use a lithium-ion battery pack from partner AESC - an expensive option, but the cost (and eventual replacement cost) will be spread out over a lease plan.

The electricity sector accounts for almost 35 percent of greenhouse gas (GHG) emissions in the United States, and 40 percent of the carbon dioxide (CO2) emissions. Over 80 percent of GHG emissions associated with electricity generation are from the combustion of coal, with nearly all the rest due to natural gas and petroleum combustion. U.S. electricity sales are split among the residential (37 percent), commercial (36 percent), and industrial (27 percent) sectors, where primary uses vary by sector. Over the past 30 years the U.S. electricity sector has become less carbon intensive, and the U.S. economy has grown less electricity-intensive.

DOE Offers $2.4 Billion to Support Next-Generation Electric Vehicles President Barack Obama announced on March 19 that DOE is offering up to $2.4 billion in American Recovery and Reinvestment Act funds to support next-generation plug-in hybrid electric vehicles and their advanced battery components. Of the $2.4 billion, $1.5 billion in grants will go to U.S. manufacturers to produce high-efficiency batteries and their components; $500 million in grants will go to U.S. manufacturers to produce other components needed for electric vehicles, such as electric motors; and $400 million will go towards projects that demonstrate and evaluate plug-in hybrids and other electric infrastructure concepts. When these plug-in hybrid vehicles are offered for sale, U.S. residents who purchase them will be able to claim a tax credit of up to $7,500. Building a plug-in hybrid vehicle industry in the United States will create tens of thousands of jobs and will reduce our nation's dependence on foreign oil.

"The Electrical Installation Guide is a single document covering the techniques, regulations and standards related to electrical installations. It is intended for electrical professionals in companies, design offices, inspection organisations, etc."

It looks ordinary, like a razor-thin metal ribbon. But the high-temperature superconductor power transmission cable the Long Island Power Authority recently installed in Ronkonkoma revolutionizes how electricity is delivered, utility and federal officials said. The cable -- which is a fraction of the size of a traditional copper wire but can carry three times the power -- made its ceremonial debut yesterday with officials from LIPA, the U.S. Department of Energy and officials from the company that makes the cable. It went online April 22, the world's first use of the new technology in a commercial power grid. Utilities around the world are looking at superconductivity to improve efficiency of their grids and make them less vulnerable to blackouts. LIPA has buried three 2,000-foot wires in its right-of-way, and it will be installing a second generation of the wire in the same area as a test. "We view superconductor power cables as an important option that will help us further enhance the reliability of our grid as we meet our customers' increasing demands for electric power," LIPA chief executive Kevin Law said. He said the new cable allows the utility to increase capacity where its system has bottlenecks while increasing reliability and longevity and lowering costs. The wire, manufactured by American Superconductor Corp., conducts 150 times the electricity of the same sized copper wires, strand-for-strand. This means transmission cables can be far smaller and still conduct as much as three to five times more power in a smaller right-of-way.

"Proceedings have been filed against: * Australia's two largest manufacturers of electrical cable, Olex Australia Pty Ltd (Olex) and Prysmian Power Cables & Systems Australia Pty Ltd (Prysmian), * the electrical wholesaling businesses L&H (which is operated by Lawrence & Hanson Group Pty Ltd) and Rexel (which is operated by Rexel Electrical Supplies Pty Ltd and Australian Regional Wholesalers Pty Ltd), * six senior executives from these manufacturing and wholesaling companies, and * an industry association, Electrical Wholesalers Association of Australia Limited (EWAA)."

London, January 5 (ANI): A ground-breaking technology that broadcasts electricity may render electrical wiring ancient history, say its inventors. The device called WiTricity beams power to laptops, mobile phones and stereos without cables or sockets.

"Vietnam is one of the few countries in the Southeast Asian region that has established regulatory bodies in the power sector. In 2004, the Electricity Reform Law was introduced to establish a competitive electricity market in the country. Reforms were initiated in 2012 and agencies such as the Directorate General of Energy (DGE) under the Ministry of Industry and Trade (MOIT) and Electricity Regulatory Authority of Vietnam (ERAV) restricted the control and ownership of transmission grid and power generation of Vietnam Electricity (EVN)."

The Japanese Electric Wire & Cable Maker's Association has announced that electric wire shipments in fiscal 2011 increased by 0.3% in total from the previous year to 685,020 tons. The year-on-year increase in shipment levels for a second consecutive year was despite the impact of the earthquake. Although those for electricity and electric machinery fell below the previous year's level, those for construction/building and automobiles recovered to increase the total figures and those for communication increased by 6.1% year-on-year to 15,728 tons. The figures for electric wire shipments for electricity declined by 13.2% year-on-year to 61,247 tons and fell significantly below the previous year's figures as electric power companies decreased capital investments in the aftermath of the earthquake. On a monthly basis, they also declined in almost all months.

According to NREL's Renewable Electricity Futures Study, the increased electric system flexibility needed to enable electricity supply-demand balance with high levels of renewable generation, can come from a portfolio of supply and demand side options, including: · Flexible conventional generation · Grid storage · New transmission · More responsive loads · Changes in power system operations

"Four years ago, the German government pledged the idea of bringing one million electric vehicles (EV) to the German roads by the year 2020. Today, approx. just 24.000 electric cars cruise the streets of Germany - a far cry from the ambitious goal once set. The published progress report of the German National Platform for Electric Mobility (NPE) was supposed to be a milestone."

Until November it was virtually impossible for a private developer of renewable energy power plants to become an independent power producer (IPP) in Mexico. Article 27 of the Mexican Constitution precluded private investment stating that electricity generation for public use is an activity to be undertaken exclusively by the Government. Mexico's enactment of a new law for the use of Renewable Energy and the Financing of the Energy Transition ( Ley para el Aprovechamiento de Energías Renovables y el Financiamiento de la Transición Energética ) substantially improves the legal framework for private investment in renewable energy projects. The law regulates renewable energy electricity generation for purposes other than providing public electricity services. The law states that the use of renewable energy for electricity generation is possible for private use and any excess energy can be sold, but only based on regulations and approvals by Mexico's energy regulatory body, CRE .

Five of the major Japanese electric wire makers, (Furukawa Electric, Hitachi Cable, Fujikura, SWCC Showa Holdings, Mitsubishi Cable Industries Ltd.) have all posted consolidated recurring losses in their business results for FY2008 ended March 2009. All except Sumitomo Electric Industries, which reported lower sales, posted losses due to the dramatic fall in copper price during H2 2008 as well as the downturn in the automotive industry. Their copper inventory valuation losses have reduced their profits significantly. Sluggish demand is reported across a range of automobile related products including copper strip for connectors, winding wire and wiring harness.

"About EV Charging Stations The power of electric vehicle chargers is expressed in kilowatts (kW) - the higher the kW the faster the vehicle gets charged. Electrical vehicle are fed through EV chargers, in AC or DC current. Straight from the grid, AC charging stations are less expensive as they do not require inverters and provide current directly to the on-board vehicle charger. DC charging stations supply current to the vehicle battery and usually provide less time to charge."
