IBM is putting smart grids on their front burner by preparing a technical framework that will help to efficiently and effectively put new technology into the old electricity distribution grid.

A company called GreenCore Air has released an air conditioner than can be powered by a single 170 watt solar panel. The GreenCore air conditioning unit can heat and cool a 600 square foot room. It runs on DC power, so there is no need to put an AC inverter between the solar panel and the air conditioner. This eliminates the power losses associated with converting AC to DC

GreenCore units are being tested by a McDonald's restaurant and the U.S. Navy.

BRUSSELS -- European Union antitrust regulators said Tuesday that they had put on hold an antitrust probe into miner BHP Billiton's bid for rival Rio Tinto Inc. because the companies have not provided information.

"One of the highlights at the booth will be the Cooled Charging Cable - the new technology which is an ideal fit for high-power charging stations. The Cooled Cable can multiply power-throughput of a charging cable and reduce charging times to below 20 minutes, making rapid charge times for all electric cars possible. This innovation puts super-fast charging within reach - even with big battery packs of new electric vehicles and trucks. The cables are thin, simple and easy to handle, bend-protected and have ideal grip position."

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

"We are putting on a new roof & the price of copper is really adding to the price of the roof. The snow slides alone are over $7,000. Is there something that we can use that looks like cooper and is still corrosive-resistant, but is less expensive? "

"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."

"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..."

Unless there is a shift in world energy policies, global energy demand is set to accelerate, putting increasing strain on the world economy and the environment.

Venture capital is one of the pulses of the industry, and so a headline that VC investments are dropping by double digits is enough to catch the eye of anyone involved in the high tech ecosphere. But when you look at more data, things don't look bleak. On one hand, according to Dow Jones VentureSource, investment is down:\n\nIn the second quarter of 2008, quarterly venture capital investment in U.S. companies slipped below the $7 billion mark for the first time in 18 months. According to the Quarterly U.S. Venture Capital Report released today by Dow Jones VentureSource (http://www.venturecapital.dowjones.com), investment fell 12% in the second quarter compared to the same period last year with $6.64 billion put into 602 deals, the lowest quarterly deal count since 2005. The $7.58 billion invested in second quarter of 2007 was the second-highest quarterly totals recorded since the end of the dot-com boom in 2001.\n\nYet it's not all bad news because there was " steady deal activity and investment in the first half of the year," according to Dow Jones VentureSource director of global research Jessica Canning.\n\n"The movement of venture dollars from the traditional areas of information technology and health care toward burgeoning sectors like renewable energy, power management, and agriculture - or 'clean technology' areas - proves that venture capitalists are making good on their promise to tap opportunities in the massive energy market," said Ms. Canning.

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 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.

In recent months, chains including Wal-Mart Stores, Kohl's, Safeway and Whole Foods Market have installed solar panels on roofs of their stores to generate electricity on a large scale. One reason they are racing is to beat a Dec. 31 deadline to gain tax advantages for these projects. So far, most chains have outfitted fewer than 10 percent of their stores. Over the long run, assuming Congress renews a favorable tax provision and more states offer incentives, the chains promise a solar construction program that would ultimately put panels atop almost every big store in the country. The trend, while not entirely new, is accelerating as the chains seize a chance to bolster their environmental credentials by cutting back on their use of electricity from coal.

COPENHAGEN, DENMARK, September 2, 2008. The Danish Ministry for Climate and Energy says a new 400 MW offshore wind farm will be built by 2012. The wind farm comes in addition to the 200 MW Rødsand II (online from 2011) and 200 MW Horns Rev II (online from 2009), and will be built between Anholt and Djursland in the Kattegat Sea between Denmark and Sweden. The location was chosen due to the possibility of connecting the wind farm more or less directly to the existing grid, which means the windmills can be put up quicker. Depending on the capacity of the windmills that will be chosen, the wind farm will have 100-175 wind mills.

The commodity super-cycle is not over, it is just pausing. For the world economy to resume growth of 5 per cent, energy supply must expand by a similar rate. But with lower oil prices and a credit crunch, energy investment is plummeting, suggesting global energy demand will eventually pick up more rapidly than productive energy capacity. Assuming the ongoing global recession does not turn into a multi-year event that pushes energy demand down structurally, steep decline rates could again put upward pressure on oil prices as soon as 2010 or 2011. In particular, if the low oil price/high cost of money environment persists for most of this year and next, our base case scenario for non-OPEC production could prove optimistic, exacerbating the second leg of the commodity super-cycle. If and when the global economy starts to recover, too many dollars chasing too few barrels will only lead to much higher oil prices.

What we're seeing now is an anti-bubble. It's across the entire economy, and in fact cleantech appears to be more insulated than many other sectors, but people just aren't putting money out there.

Mr Obama's stimulus includes calls for $38bn in direct government spending and $18bn in tax breaks for clean energy spread over the next 10 years, according to Dewey & LeBoeuf, the law firm. Owners of solar, wind, and other clean energy facilities will be able to claim tax credits against the cost of new equipment, helping attract big institutional investors who have been put off investing in clean energy because of uncertainty about taxes. But the short timeframe - credits can only be claimed for projects that are up and running within the next three to four years - means projects still on the drawing board may not be ready in time to qualify.
