"The copper industry is already facing substitution challenges from materials like aluminium and needs to use technology to help ensure larger-scale, more permanent switches are not made, industry participants said. A group of panelists at the Metal Bulletin and American Metal Market Copper Seminar in New York on Wednesday June 6 said that while technology is clearly an opportunity for the industry, there are still some risks. According to Freeport McMoRan vp sales and marketing Steve Higgins, much of the "easy substitution" - such as plumbing tube or transformer lines - has already happened. "Substitution is less than 2% of refined demand today… It's a bit troubling, but it happens," he said. "The bigger worry is that aluminium is going to make inroads into products that have high switching costs - ACR tubing, motors, or into some medium to high voltage power cables and the like that the manufacturers have to go in and put in a lot of capital costs to convert. Once converted, switching back becomes "extraordinarily difficult," he said. "That's the biggest risk to our market as I..."

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

SureWest had said it was contemplating such services when the company began offering broadband via bonded ADSL2+ in its incumbent territory last fall, including 10-megabit-per-second services. The company already offers IPTV through its fiber-to-the-premises network, but its bonded ADSL2+ customers have so far only had access to SureWest's voice and data services. (The company has offered IPTV over copper on a very limited basis even before it began line bonding. It offers IPTV over copper to about 2500 customers today, mostly to those with short loops and modest standard-definition video needs.) The new copper-based IPTV services, which will be available to 15,000 homes in December and another 10,000 by next June, are enabled in part by the company's recent switch from Minerva middleware to Microsoft's Mediaroom and by its use of MPEG-4 encoding for video compression.

It's been a long, challenging endeavor, but there are signs that the economic ecosystem built up around wave and tidal power generation is at long last gathering enough momentum to make the jump from R&D-driven to full-fledged commercial industry. Scotland, with its long stretches of west-facing coastlines, North Atlantic latitude and longstanding tradition of maritime engineering and commerce, is now at the leading edge of change when it comes to fostering development of marine renewables. Wavegen's Limpet 500 system has been pumping electricity from the western Scottish Isle of Islay shoreline since 2000 while the company and project developer npower renewables have continued to move forward with plans to develop the Siadar Wave Energy Project, potentially the first under the Scottish government's Marine Supply Obligation program. Marine Current Turbines is getting ready to flip the switch and fully commission a grid-connected 1.2-megawatt (MW) Seagen tidal turbine-based system in Northern Ireland's Strangford Narrow, while elsewhere in the EU, project developers and the marine renewables community await the much-anticipated commissioning of Pelamis's novel, serpent-like wave power system off the northern Portuguese coast.

An energy ministry official said that the mines have been forced to scale down operations and to switch off non-essential equipment to ease power shortages. "This will surely have a negative effect on copper production this year," he said on condition of anonymity.

"Asia Pacific: The Largest Market for Switchgear The Asia-Pacific region holds the largest market for switchgear, driven largely by the number of transmission and distribution line up gradations and developments in the South East Asia. These developments are due to its growing energy needs is the major growth engine for this market. Utilities: Biggest Market by Application Switchgear is mostly used in Transmission & Distribution by power utility companies. They are used for switching the equipment or the circuit during the event of fault. With the growing transmission and distribution network across globe, the number of substations will keep on increasing. This increasing number of substations is expected to increase the use and demand for switchgears. Maximum T&D expansion projects are ongoing in Asia-Pacific and the market is expected to be the biggest and the fastest growing market for switchgear. The Switchgear industry is fragmented and offers several opportunities for consolidation and growth in efficiency through an increase in economies of scale. The industry has low entry and exit barriers. This is a major driver of the Switchgear Market. Top players of the PR market are ABB (Switzerland), Eaton Corporation (Ireland), GE (U.S.), and Siemens AG (Germany)."
