"Regulatory cooperation at regional, continental and world level is a trend which is set to continue. The International Confederation of Energy Regulators (ICER), which brings together more than 200 regulators from around the world has proved to be a very valuable platform for the exchange of good regulatory practice and facilitating regulatory cooperation.

"As a storm raged over the government's directive to the Clean Energy Finance Corporation to no longer back wind energy projects, it emerged that it has also put a stop to solar investments other than the largest industrial-scale projects."

"Centuries ago, Nikola Tesla envisioned and pioneered the concept of wirelessly transmitting power over long distances through the Earth's ionosphere. In the recent past, wireless energy transfer has occurred by way of an electromagnetic (EM) field set to a certain frequency level. While transmission efficiency over longer distances is attained to an extent by this method, it becomes increasingly difficult when complicated pointing and tracking mechanisms are mandatory to maintain the right wavelength between the transmitter and the receiver. Another drawback to this approach is that any object that falls between the transmitter and the receiver impedes the beam, thus interrupting power transmission to a potentially harmful degree if the power level goes beyond a certain threshold point. Even though microwave frequencies could prove effective to transmit power over long distances through a radiated EM field, the aforementioned caveats still apply. The other possible way to wirelessly transmit power is by non-radiative fields. For instance, a transformer operates by magnetic induction drawing similarities to wireless power transfer. Energy transfer in a transformer happens from the primary coil to a secondary coil in the absence of a direct electrical connection. The same approach can be seen in inductive chargers found in electric toothbrushes, for example. However, for this functionality to operate smoothly, primary and secondary coils must be positioned in close proximity to one another."

rance-based energy company GDF Suez, South Korean Daewoo International, and UAE-based AES are among 16 firms currently being considered to construct the Fujeij power plant, a 90MW wind farm in Fujeij, near Shobak, around 200 kilometres south of Jordan's capital Amman. Offers for the Fujeij plant are to be submitted by December 19, 2010, with the winning bid to be announced in February 2011.

BRUSSELS (Reuters) - The European Commission will launch a raft of proposals on Wednesday to curb the environmental impact of consumerism in the 27-nation EU by supporting eco-friendly products and technology. The plan comes as the European Union moves to cut energy consumption amid soaring fuel and power prices and as part of its ambitious mid-term goal of cutting carbon dioxide emissions by one fifth by 2020, compared to 1990 levels. "This will mainly be targeted at products that use a lot of energy, such as computers, televisions, water heaters and industrial fans," a source at the Commission, the bloc's executive arm, said on Monday.

The solar industry and semiconductor industry are intimately connected. Both industries rely on silicon and both use much of the same processing technology and supply chain to produce their products. Nowhere has this connection been on better display than last week at the Moscone Center in San Francisco California, where the Intersolar North America made its debut in conjunction with SEMICON West 2008. The show provided an opportunity for those in the two industries to connect and allowed those companies that work in both spaces to showcase their collective efforts. According to Chris O'Brien, Head of Market Development and Government Relations for North America for Oerlikon Solar, holding the two conferences together gave companies greater exposure and showed the promise of the U.S. solar market. In recent months a number of traditional semiconductor companies including Intel and National Semiconductor have made announcements that they are making plans to enter the solar industry in one way or another. Intel spun off it's solar research area into a new solar company called SpectraWatt. National Semiconductor announced that it will be introducing it's first solar product, SolarMagic, that could raise the efficiency of residential and industrial solar systems. Kevin Kayser, Senior Marketing Manager at National said that he product will be targeted at installers and integrators and much planning went into the company's decision to enter the solar space. "Photovoltaics currently has less than 1% of the energy market, but we think it has potentially one of the fastest growth rates of any alternative energy source. Now certainly we're looking at wind, we're looking geothermal, we're looking at other sources, but from an electronics point of view we saw that we had the most immediate potential impact in solar photovoltaics," Kayser said.

Despite a slowdown in the global economy and a softening in demand for aluminium rolled products in some regions, JSE-listed aluminium reroller Hulamin expected global demand to increase this year. CEO Alan Fourie on Tuesday commented that the company, which exported about 70% of its products, had seen some softening in demand for aluminium rolled products in some regions, but added that demand for these products was expected to grow by between 5% and 7% this year. "Obviously the slowdown of the [global] economy puts pressure on margins, it is an economic consequence, but we are still selling into a growing international market," he said. Locally, however, the softening economic climate was expected to impact on sales volumes for the second half of the year. However, Hulamin expected these high-value products to continue growing as a percentage of its sales in the next few years. Fourie noted that five years ago, these products equated to just over 50% of its sales volumes, while their contribution was just below 60% in 2007. They now comprised about 64% of its total sales volumes. Meanwhile, Hulamin stated that its costs had increased by 16%, influenced by a 58% increase in energy costs, increasing alloying costs caused by magnesium prices rising from $2 000/t to $4 500/t, and increases in other metals. Excluding the cost of increasing energy and metals prices, the company's costs had increased by 6%. Fourie noted that while the rising aluminium costs did not affect its profitability, it did have an effect on its working capital. "We hold aluminium in our working capital. So when the aluminium price increases, the cash tied up in working capital increases and we have seen a significant increase in working capital during this period, because the rand price of aluminium has increased by close to 40% in the last six months," he explained. Further, Fourie did not expect the increasing electricity prices to have too great an impact on its futu

A U.S. government official said dramatic improvements to lithium batteries are needed before they can efficiently power vehicles. Experts believe lithium-ion batteries are widely predicted to replace nickel metal-hydride batteries currently used in most hybrid vehicles like Toyota Co's popular Prius. The biggest challenges are extending the life of high-power lithium batteries and bringing down their relatively high cost, Tien Duong of the U.S. Department of Energy said on the sidelines of a lithium battery conference held at this government laboratory. "Life means 10 years, plus. For hybrids we know (their batteries) last 10 years plus. For the PHEV (plug-in electric vehicle), we don't know," Duong said. He did not specify what the costs should be. "One of the phenomenons that cuts short the life of the battery is power. You may have a lot of energy, but if you run out of power, that's no good," he said.

Batteries are becoming increasingly important to our lives. Not only to sustain our rapidly expanding wireless technology requirements, but also to support our need to travel about. With hybrids, plug in hybrids and fully electric vehicles beginning to provide us with more cost effective transport, we're bound to depend more and more on batteries. And at a larger scale, as we integrate more renewable sources of energy into our electricity grid, we'll need to manage supplies with more uncertainty. So, there is likely to be an increased need for energy storage solutions to help temper the ups and downs of power supply irregularity.
