Miniature Nuclear Plants Seek Approval to Work in U.S (Update1) - BusinessWeek - 2 views

  •  
    Manufacturers of refrigerator-sized nuclear reactors will seek approval from U.S. authorities within a year to help supply the world's growing electricity demand. John Deal, chief executive officer of Hyperion Power Generation Inc., intends to apply for a license "within a year" for plants that would power a small factory or town too remote for traditional utility grid connections. The Santa Fe, New Mexico-based company and Japan's Toshiba Corp. are vying for a head start over reactor makers General Electric Co. and Areva SA in downsizing nuclear technology and aim to submit license applications in the next year to U.S. regulators. They're seeking to tap a market that has generated about $135 billion in pending orders for large nuclear plants.

Vast northeast China to benefit from wind power - 0 views

  •  
    "In the remote county of Tongyu in northeast China's Jilin Province, 14-year-old Li Ruixue has more memories about sandstorms rather than colorful flowers and clean rivers, due to the howling winds that sweep the area from spring to winter every year. Sand-filled winds from Horqin often leaves local farmers' land barren and the United Nations Educational, Scientific and Cultural Organization (UNESCO) has described the county as being one of the areas of the world most unfit for human living. But the Chinese government's new strategy to find more renewable energy might provide one of the country's poorest counties with the opportunity to improve its way of life. The reason for hope is a wind farm with a combined installed capacity of 1.9 million Kilowatt that will soon be completed in the county."

Enterprise PCs work while they sleep - saving energy and money - with new software - 0 views

  •  
    "Personal computers in enterprise environments save energy and money by "sleep-working," thanks to new software called SleepServer created by computer scientists from the University of California, San Diego. Sleep-working enterprise PCs are accessible via remote connections and maintain their presence on voice over IP, instant messaging, and peer-to-peer networks even though the PCs are in low-power sleep mode. SleepServer can reduce energy consumption on enterprise PCs previously running 24/7 by an average of 60 percent, according to a new peer-reviewed study presented by UC San Diego computer scientists on June 24 at the 2010 USENIX Annual Technical Conference in Boston.

Distributed Energy First, Wait On New Transmission Lines - 0 views

  • Only recently have we begun to realize that a renewable energy future does not inevitably mean a decentralized energy future. Indeed, right now the fastest growing part of the renewable energy industry may be the large solar central power systems being built in remote locations in the southwest to serve customers in Los Angeles, and the huge wind farms being built in the Midwest to serve customers in Chicago.

EERE News: Report: Electric Utilities Investing Billions in Transmission - 0 views

  • Report: Electric Utilities Investing Billions in Transmission The U.S. electric utility industry invested $6.9 billion in transmission projects in 2006, and members of the Edison Electric Institute (EEI) plan to invest another $38.1 billion from 2007 to 2010, according to a new EEI report. This represents a 60% increase above the amount invested from 2003 to 2006. EEI is the association of shareholder-owned U.S. electric companies and represents about 70% of the U.S. electric power industry. The EEI report notes that transmission lines are being added for a variety of reasons, and one is to connect remote renewable energy resources to the electrical grid.

ApplianceMagazine.com | Sustainability in Home Appliances - Europe Report - 0 views

  • The buzzword these days is sustainability. A few years ago, this meant responsibility in a broader sense. Now, the focus is more on actual products. So, which alternatives can the industry offer to the appliance industry’s well-known products? And are these actually large, revolutionary steps? In white-good appliances, there are several alternatives. Europeans switched to high-efficiency horizontal-drum washers a long time ago—a revolutionary technology that left little room for improvement. The next big step might be to heat the water with gas instead of electricity. Martin Elektrotechnik is one German company that offers an automatic external water selector. It detects activation of the heating element and switches accordingly. However, at 285 euros, sales have been limited. The same unit can also be used for the dishwasher. The clothes dryer is another story. These appliances use 3–4 kWh per run, and there are more-efficient alternatives—the gas dryer and the heat pump dryer. Europe has a few gas dryer manufacturers, including UK-based Crosslee with its White Knight brand and Miele. Despite the advantages of efficiency and shorter drying time, they have not caught on in the larger marketplace. They only come as vented units, not as condenser units, and connecting the gas is just too much of a hurdle for many consumers, even when there is a click-on gas connector system available. Heat pump dryers are relatively new. Electrolux started in 1997 with an almost hand-built model under their premium, environmentally oriented AEG brand. At a price point of 1500 euros, even wealthy German consumers would not buy many of them. In 2005, the company started selling a redesigned model, called Öko-Lavatherm. It claimed energy savings up to 40% for around 700 euros, which is more in line with the cost of other premium models. Other manufacturers of heat pump dryers include Blomberg, the German brand owned by Turkish market leader Arçelik, and Swiss Schulthess. In cooling, there have been no large breakthroughs. Years ago, there was talk of vacuum-insulated panels, but no models were produced. Instead, there have been a number of smaller-scale efficiency improvements, and today, the industry suggests that consumers simply buy new, extraefficient models. AEG offers a typical case: a 300-L cooler/freezer in the A++ efficiency class now uses only 200 kWh per year, whereas a 10-year-old model used as much as 500 kWh. And what about the heating industry? Remember that in chilly Europe, heating is the largest energy user. The advice here is almost the same as for white-good appliances—just replace old equipment. There are still many noncondenser boilers on the market and a significant percentage of houses are insufficiently insulated. German Vaillant is calling its efficiency initiative "Generation Efficiency." But, like the home appliances market, progress is gradual. Current boilers are already highly efficient. Other technologies, such as solar panels, combined heat-and-power units, and heat pumps, catch on more slowly. Still, there were 1.1 million renewable energy units sold in Europe in 2006 compared with 440,000 just two years earlier. Some of the company’s smaller steps forward were seen at ISH. The small Vaillant ecoCOMPACT combiboiler now has a high-efficiency pump, which is said to reduce electricity use by 50%. Hot water output is higher for user comfort, and there are new modules for remote access for better preventive service. The main obstacle for customers wanting a heat pump is the installation, as sometimes complex drilling is needed. Vaillant solved that issue by taking over a drilling company and offers all of the services for a fixed price, just like its competitor, BBT Thermotechnik. Across the board, it seems manufacturers continue their efforts toward sustainability. The question now seems to be whether or not consumers will take advantage of the technology.
