Gentlemen, start your debating—according to the National Oceanic and Atmospheric Administration (NOAA), the July average was the highest recorded ocean temperature in 128 years. July’s worldwide average of 62.6 will revive the global warming debates, inasmuch as some will cite this as evidence of climate change.
Energy efficiency standards have typically concentrated on two ends of the spectrum – full load efficiency and standby power. As a result, popular PWM buck regulators available today demonstrate high efficiency at full load (>80%) levels and incorporate standby circuitry to comply with the <1W and lower initiatives. Improved efficiency at all operating points is an important concern in the design of next generation “green” products.
Fool me once, shame on you. Fool me twice….well, you know the rest. When Raser Technologies claimed their re-jiggered Electric Hummer got 100 miles per gallon, I thought they fudged a few numbers. But for GM to claim 230 MPG for the Volt…well, that’s taking a trip to fantasyland, with magical goblins and unicorns.
Cars and light trucks sold in July got more miles per gallon than those sold in previous months, say researchers, who credit the Cash for Clunkers program. The average mileage for new vehicles rose from 21.4 miles per gallon in June to 22.1 mpg in July. That may not sound like much, but it's
One of the hottest trends in power is “conductive ink”—that is, ink that conducts electricity. Thus, we’ve seen the emergence of ultra-thin power solutions such as Fraunhofer Research Institution's silk-screened batteries. One of the variants is printable solar cells, a technology still in its infancy. But the US Air Force, in conjunction with Plextronics, has developed what they purport to be a “significant step forward in printing inexpensive solar cells.”
The Consumer Electronics Association (CEA) and the Information Technology Industry Council (ITI) have filed a legal challenge against a New York City law mandating door-to-door collection of e-waste. Local Law No. 13, taking effect July 31st, forces all electronic manufacturers doing business in NYC to provide free door-to-door collection services for covered equipment.

The Korea Advanced Institute of Science and Technology (KAIST) has purportedly created an Organic Light Emitting Diode that is 75% more efficient than previous models. Led by Prof. Kyung-Cheol Choi, the KAIST team discovered a new type of surface plasmon enhanced OLED. KAIST explains their finding thusly: “For surface plasmon localization, silver nanoparticles were thermally deposited in a high vacuum on cathode.
GE announced today that by 2015 it is developing a turn-key product portfolio that will empower consumers to build — both new home builders and existing homeowners — to efficiently consume, manage and generate electricity to enable an overall net zero annual energy.
Who knew those shady vendors hawking silk-screened t-shirts at tourist traps were leading the tech revolution? Actually, that claim belongs to the Fraunhofer Research Institution, but who’s keeping track? The German institute has developed a printable battery that is produced using a silk-screening process similar to that used in t-shirts.
IMEC announced that it has established new partnerships with solar cell material and equipment suppliers. These companies, including MEMC Electronic Materials Inc., Leybold Optics Dresden GmbH, Roth & Rau AG, and Mallinckrodt Baker B.V., have concluded joint-development agreements with IMEC in the frame of IMEC’s newly launched wafer-based silicon photovoltaics industrial affiliation program (IIAP).
A recent survey of electrical and lighting contractors demonstrates their importance in the specifying and recommendation of LED lighting products for building projects. According to the survey respondents, contractors are involved in recommending LED lighting more than 70% of the time. Yet a majority of respondents said they would be interested in receiving more training on product installation, benefits, and layout
The world's first piloted aircraft capable of taking to the air using only power from fuel cells took off in Germany Tuesday, producing zero carbon dioxide emissions, its makers said. "We have improved the performance capabilities and efficiency of the fuel cell to such an extent that a piloted aircraft is now able to take off using it," said Johann-Dietrich Woerner from the German Aerospace Center (DLR).
Those writing incandescent’s obituary may want to stay their pen. The NY Times reports on the efforts towards modernizing the “Edison lightbulb.” Leading the pack is Philips’ Halogena Energy Savers, purportedly 30% more efficient than similar incandescent bulbs. The 2007 Energy Independence and Security Act sounded the death knell for traditional incandescents. While it doesn’t ban incandescents, it does set wattage limitations and other restrictions
China said on Thursday that it was "firmly" opposed to provisions in a new US clean energy bill that will make it easier to impose trade penalties on nations that reject limits to globe-warming pollution. "China is firmly opposed to such measures," vice foreign minister He Yafei told reporters in Beijing. "We are firmly against such attempts to advance trade protectionism under the pretext of climate change. It is not conducive to world economic recovery. It serves nobody's interests."
President Barack Obama, buoyed by a domestic victory on climate policy, faces his first foreign test on the issue next week at a forum that could boost the chances of reaching a U.N. global warming pact this year.
To follow up on an earlier story, the EPA has granted California’s request for exemption from federal tailpipe emissions standards. The decision is effective immediately for California plus 13 other states and Washington DC. It allows them to regulate emissions for model years 2009-2011, one year before the federal standards take effect. Says EPA Administrator Lisa Jackson, “This decision puts the law and science first…this waiver is consistent with the Clean Air Act as it’s been used for the last 40 years

Today, the Obama Administration announced $8 billion in conditional loan commitments for the development of innovative, advanced vehicle technologies that will create thousands of green jobs while helping reduce the nation’s dangerous dependence on foreign oil. The loan commitments announced today by the President include $5.9 billion for Ford Motor Company to transform factories across Illinois, Kentucky, Michigan, Missouri, and Ohio to produce 13 more fuel efficient models
The AP reports that “climate bill” proponents had agreed to concessions in an attempt to sway wary Democrats. In this case, “climate bill” refers to the “Cap and Trade” proposal sought by Barack Obama and activists for years. Along with universal healthcare, Cap and Trade has been a major priority of the Obama administration. Will these concessions finally enable passage of Cap and Trade legislation?
Outside Saginaw, Mich., an old auto town of 56,000 people about 100 miles northwest of Detroit, a company making silicon for solar panels is doing the exact opposite of the Big Three. It's hiring.
Whether you design drugs, manufacture consumer products or airplanes, or search for oil, improving your computing performance will improve your competitiveness. But what do you do when the “need for speed” collides with demands for reduced operating budgets and lower environmental impact?
