"Ten cables in total are being introduced, with five using copper as a conductor material and five using aluminum. New aluminum cable connection technology is also being launched at the show."

Here's the five cleantech trends

The Y. S. Sun Green Building Research Center, which costs TWD87,000 ($296,1) per 36 square feet, adopts 13 different green building design methods, including five natural ventilation energy-saving methods, two equipment reduction methods, and five equipment energy-saving technologies and renewable energy technologies.

Copper prices tumbled to a five-week low Thursday on expectations that falling demand from China and a slowdown in the U.S. housing market will lead to a surplus of the metal. Other commodities traded mixed, with crude oil rebounding slightly and gold, silver and soybeans falling. Corn and wheat futures rose. China, the world's biggest buyer of copper, has been importing less of the metal since the completion of most major construction projects heading into the Beijing summer Olympics. Copper imports in June fell 20 percent compared to May, China's custom's agency said this month. As a result, stockpiles of the metal have swelled in Shanghai and London, helping drive down prices.

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.

The Policy Brief for a Global Green New Deal, developed by economists and the UN ahead of the G-20 meeting of world leaders in London in early April, highlights the benefits of investing a significant amount of the $3 trillion-worth of global stimulus packages in five areas. According to a news release issued by the UN Environment Programme (UNEP), these areas include raising the energy efficiency of old and new buildings, as well as renewable energies including wind, solar, geothermal and biomass.

""We have developed several new solutions, which can provide clear weight and cost saving opportunities to manufacturers of such commercial vehicles as trucks, buses as well as agricultural, industrial and construction equipment", stated Dr Andreas Brand, member of Leoni AG's Management Board with responsibility for the Wiring Systems Division. "We are confident that we will grow our business with the CV industry by more than five per cent per year until 2025." Alternative conductors save weight and cost In terms of weight optimisation, Leoni can reduce the harnesses' weight by replacing conventional wires. Alongside copper wires with smaller cross-sections, the Company provides the CV market with a range of wires made of aluminium for the power segment, i.e. with a cross-section between 10 mm2 and 110 mm2 and even larger. Although the aluminium conductors have a larger cross-section in order to deliver the same electrical conductivity, aluminium technology results in a noticeable weight reduction. On its booth, Leoni will show its busbar, a solid aluminium conductor, which can be bent in three dimensions and weighs only about half as much as the conventional copper component. Leoni will also show various conductor solutions based on copper. These can be used where mechanical strength as well as electrical conductivity is required. For example, a copper wire with a cross-section of 0.75 mm² could potentially be replaced by a smaller wire cross section, such as a 0.50 mm² or a 0.35 mm². Thanks to the use of less conductor material, Leoni's customers can not just reduce the weight of their vehicles, but also benefit in terms of cost savings."

China's government recently announced its 12th five-year plan for its energy industry, and it said it will build a 200,000km extra high voltage (EHV) power grid with capacity higher than 330 KV by 2015. Also announced, the government has set its compound annual growth rate for power installed capacity at 9.0% from 2011-2015, lower than the 13.3% from 2005-2010, demonstrating its intention to slow down investment in the power industry. It expects its installed capacity will be expanded to 1.49 billion KW, up 9.0% from 970 million KW at the end of 2010.

"The primary demand for increased consumption is expected to come from the power sector, where aluminium is a cheaper, lightweight substitute for copper in transmission and distribution, it said. Power distribution companies and government are planning investment of Rs. 4.3 lakh crore over the next five years to expand the transmission and distribution networ"

The SERC (State Electricity Regulatory Commission) has released stricter technical regulations, especially for LVRT (Low Voltage Ride Through) reformation. Additionally, 18 industry standards have been released in November 2011 by the National Bureau of Energy. There are two immediate effects of the regulatory changes. Adding a LVRT capability will increase the cost of the Chinese turbines. This, coupled with slower demand, will lead to a squeezing out of the marginal producers who won't be able to afford to fit new equipment. Thus, the domestic wind power manufacturing sector in China is poised for tough times, when consolidation may even change the positioning of the top five players.
