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

A vote could come as early as this week in the U.S. Senate on a bill introduced by Senate Tax Committee Chairman Max Baucus (D-MT) and Senate Majority Leader Harry Reid (D-NV) containing a one-year renewable energy production tax credit (PTC) extension and a small wind turbine investment tax credit. The Senate bill, S. 3335, contains a one-year PTC extension at its current value. After December 31, 2009, any further extension would include the "presumption" of a cost cap, which would, through a complex formula, put a ceiling on the value of the credits of no greater than 35% of project value. The small wind ITC has a cap of US $4,000 per system.The 10-year cost for the PTC, including all technologies to which it applies, is projected to be approximately US $7 billion, while the ITC, which includes solar, would cost approximately US $907 million over 10 years. The bill also includes provisions to extend through 2014 the tax credits for solar energy, fuel cell and microturbine property, as well as the residential energy efficient property tax credit. Marine renewable energies could also benefit from the bill as credits to build wave, tidal, current and ocean thermal energy conversion systems of at least 150 kilowatts (kW) are extended through the end of 2011.

There is no consensus among the analysts on Inmet Mining Corp.'s (IEMMF.PK) C$345-million hostile bid to take out its junior partner Petaquilla Copper Ltd. (PTQLF.PK). On the positive side, Raymond James analyst Tom Meyer wrote that by moving its stake in the Petaquilla copper project from 48% to 74%, Inmet would gain "important strategic flexibility" and lower the risk profile on the project. If Petaquilla Copper was bought out, Inmet and Teck Cominco Ltd. (TCK) would be the sole remaining partners and the legal action between Petaquilla Copper and Teck would presumably end. In a note, Mr. Meyer wrote: With two shareholders in the project as opposed to three, we believe it is safe to say that rational decision-making may likely become less of a bottleneck and the project can move forward at a faster rate. He added that by going to a 74% interest, Inmet could be in a position to potentially buy Teck Cominco's stake as well. Analyst Greg Barnes from TD Newcrest presents the negative view. He wrote that the economics of the Petaquilla project are "marginal" and figures that it would need a long-term copper price above $2.25 a pound for it to work. He also noted a "lack of clarity" on how Inmet could optimize value from the project. He wrote: Until Inmet is able to verify improved project parameters, we feel that the company is overpaying for a project that has less than compelling economics. Over at UBS Securities, analyst Onno Rutten's opinion is a little more mixed. He thinks that Inmet's C$2.00-a-share offer for Petaquilla Copper is "a steep premium," but would accelerate the project's development if it is successful. That could unlock value for Inmet. However, Mr. Rutten shares Mr. Barnes' concerns about the risks of the project; he pointed out that Inmet, a C$3-billion company, is trying to build a project that costs close to C$4-billion. He also said that Petaquilla needs strong copper prices to be economic. But he wrote that the financi

MOSCOW - In what would be one of the biggest mining deals in Russia this year, the metals tycoon Mikhail D. Prokhorov announced on Tuesday that he would sell 16.6 percent of the Arctic mining giant Norilsk Nickel to his former business partner, Vladimir O. Potanin. The two tycoons agreed last year to divide their holdings in Norilsk, a Russian factory founded by Stalin, whose value soared along with high commodity prices. Norilsk is the world's largest producer of nickel, a key alloy in stainless steel. Under the terms, as laid out in a statement from Mr. Prokhorov's investment company, Onexim, Mr. Potanin agreed to pay $10 billion for the 16.6 percent, in $6.5 billion cash and 35.2 percent of the shares in another mining company, Polyus Gold. The deal valued Norilsk Nickel at $315 a share, well above Monday's closing price of $216, and despite a recent drop in nickel prices, concerns of an economic slowdown and diminished demand for stainless steel.

According to a new technical market research report from BCC Research, the domestic market for wind turbine components and systems will be worth $60.9 billion in 2013. This represents an increase from the 2007 market value of $7.9 billion and the estimated 2008 market value of $11.2 billion. The compound annual growth rate (CAGR) between 2008 and 2013 is expected to be 40.0%. \n\nThe market is analyzed by state and includes the top ten spenders on wind turbine technology: Texas, California, Iowa, Minnesota, Washington, Oregon, Colorado, New York, Kansas and Illinois. Texas has the largest statewide expenditure, exceeding $2.4 billion in 2007 and an estimated $3.0 billion in 2008. This should grow at a CAGR of 38.0% to reach $15.2 billion in 2013. \n

The road to grid parity for PV power generation will be difficult, needing five or more years to compete with utility power, unsubsidized, on a large scale, noted Mark Thirsk, managing partner at Linx Consulting, at a recent SEMI PV forecast luncheon (Sept. 18) in Santa Clara, CA Most input materials for PV production are in relative oversupply and will not constrain production, Thirsk pointed out - and for this reason manufacturers are conservative about capacity investment. In particular, his PV module production forecast (see Fig. 1, above) shows an overstep in demand in 2008. One reason for suppliers' reluctance to build capacity for entering the silicon supply chain is that it is an inefficient process. "Only about 15% of all the silicon going into the supply chain goes into the wafers, so it's a pretty wasteful and capital intensive process, so there is a lot of reluctance to build capacity," said Thirsk. Despite the efficiency challenges, Thirsk's forecast indicates that an oversupply may occur in 2009 Because >40% of PV grade silicon is lost at the wafering step, Thirsk believes this represents a significant opportunity for the right technology. Additionally, diamond wire is a potential replacement for slurry technology, but this technology is still immature. In the crystalline silicon (c-Si) value chain, Thirsk sees opportunities for optimizing mono-crystalline wafers with metal wrap technology and backside contacts; process optimization and material improvements would improve cell efficiency, and glass, wafer, backsheet, and grid improvements can enable more efficient light capture. Looking ahead, Thirsk told the audience that while thin-film technologies will enjoy strong growth "and may be more attractive to value-add materials and equipment suppliers, thin-film cell production will remain a minority share for the medium term." (see Fig. 3, below) He closed his presentation encouraging the creation of a Moore's Law type of roadmap for the PV

"What are the most important key performance indicators? There are, for example, indicators defining the temperature changes in reference rooms. This includes what is referred to as hours of overheating in summer. If the room temperature exceeds 26 degrees Celsius during more than 10 percent of the hours of use during a year, the room comfort is no longer achieved. Other indicators measure air quality. For example, there are CO2 sensors or so-called VOC-sensors that detect certain scents emitted by the users themselves. If the data exceed certain values, the performance in terms of air quality is not considered as good. In addition, there are energy performance indicators, such as an indicator for the overall energy efficiency of a building. We simply measure the energy that is supplied to the building. We then compare the data to pre-calculated values. We can then evaluate whether the building achieves the desired energy performance. Another indicator is the so-called net energy consumption. This is the energy that users actually have to pay for. "

Beginning with prevention, Hydro One taught employees how to better secure materials, and it began replacing copper groundings with a copper-clad alternative that has little scrap value. Alongside this material swap, signage was installed to inform thieves that the material they were targeting was not pure copper and had little value.

As the economy attempts to take off from the current position, the power sector holds the key to support rapid economic growth in the currently power starved country. This is likely to create significant investment opportunities in the power sector. Currently, there exists a major power crisis in the country. The scope to bridge the impending power demand-supply gap offers huge investment opportunities for both the multinational and domestic companies across the power industry value chain from generation to transmission and distribution and in distributed power generation including power rental sector

"Carbon Nanotubes (CNTs) have not yet met commercial expectations from a decade ago, and now hot on its heels is graphene. Graphene is considered a hot candidate for applications such as computers, displays, photovoltaics, and flexible electronics. IDTechEx market forecasts indicate that CNT and graphene transistors may be commercially available in volume from 2015 onwards, according to the new report \"Carbon Nanotubes and Graphene for Electronics Applications 2011-2021\". According to IDTechEx, the biggest opportunity for both materials is in printed and potentially printed electronics, where the value of these devices that partly incorporate these materials will reach over $44 billion in 2021."

"There will also be a big focus on renovating older buildings. This sector accounts for 40% of Europe's energy consumption and the proposal aims to create a building renovation market with a value of up to 120bn euros by 2030."

It was reported that the value of output at Canghuan Copper Products Co. Ltd. Reached RMB2.9B in 2011. This represents growth of 32% y-o-y. The company, which is owned by the Golden Dragon Group, produces high precision tubes for air conditioning, oxygen-free copper tubes for the solar power sector, as well as microelectronic components anf radio-frequency cables. In January Canghuan Copper began an expansion project which will increase its production capacity from 5,000t/y to 100,000t/y.
