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
Providing usable electrical power from waste, Innovative Energy Systems (IES) has developed a clean energy solution that recovers methane gas from landfills and converts it into electricity.
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?
The fledgling renewable energy industry has grown steadily over much of the past decade, adding jobs at more than twice the national rate, according to a Pew Charitable Trusts study released Wednesday. Solar and wind-power companies, energy-efficient light bulb makers, environmental engineering firms and others expanded their work force by 9.1 percent from 1998 to 2007, the latest year available, according to Pew. The average job growth in all industries was 3.7 percent during the same period.
Global warming is uprooting people from their homes and, left unchecked, could lead to the greatest human migration in history, said a report released Wednesday. Estimates vary on how many people are on the move because of climate change, but the report cites predictions from the International Organization for Migration that 200 million people will be displaced by environmental pressures by 2050.
House Republicans are calling for a hundred new nuclear power plants to be built in the next two decades as part of an energy plan they say is a better alternative than one championed by Democrats. The legislation unveiled by the GOP Wednesday would also increase production of oil and gas offshore, open the Arctic National Wildlife Refuge to drilling and spur refinery construction.
Columbia Tech, a US-based contract manufacturer, today announced its partnership with Massachusetts-based Owl Power to manufacture the company’s Vegawatt cogeneration system.
The most comprehensive modeling yet carried out on the likelihood of how much hotter the Earth's climate will get in this century shows that without rapid and massive action, the problem will be about twice as severe as previously estimated six years ago - and could be even worse than that.
President Barack Obama said Friday he was increasingly hopeful that the United States can lead the way on climate change, six months before crunch global talks in Copenhagen. "I'm actually more optimistic than I was about America being able to take leadership on this issue, joining Europe, which over the last several years has been ahead of us on this issue," Obama said after talks with Chancellor Angela Merkel in Germany.
Toyota said Wednesday it will start leasing plug-in hybrid cars, that are even greener than its hit Prius, by the end of this year in the U.S., Japan and Europe.Toyota Motor Corp., the world's top automaker, will start leasing 200 plug-ins in Japan, 150 in the U.S. and 150 in Europe, mostly for rental, such as through special government-backed programs, it said in a release. Toyota will for the first time use lithium-ion batteries in the plug-ins. The batteries are already used in some cars but more common in laptops and other gadgets. Toyota hybrids now use nickel-metal hydride batteries. Using a lithium-ion battery will produce more energy, allowing the car to run more as an electric vehicle, but there have been some technological hurdles.
Here are a couple of articles on efficiency in flywheel and electro-optical systems from Douglas Electrical Components and Wavelength Electronics.
The South Korean city of Ulsan lets water generated from processing food waste run off into the ocean, which can generate methane gas harmful to the environment. Now, with the help of a Swedish company, it is going to start converting that waste water into biogas, a type of clean fuel that can be used as power to heat buildings and even power vehicles.
President Barack Obama wants drivers to go farther on a gallon of gas and cause less damage to the environment — and be willing to pick up the tab.
GE announced today that it will open a new, state-of-the-art battery manufacturing plant in Upstate New York that will serve as the main manufacturing facility for GE’s newly formed battery business. The initial investment in the factory will be $100 million. It will be located in the Capital Region and will create 350 new manufacturing jobs at GE and thousands more in the supply chain.
Compared to ethanol used for internal combustion engines, researcher say that bioelectricity used for battery-powered vehicles would deliver an average of 80% more miles of transportation per acre of crops, while also providing double the greenhouse gas offsets to mitigate climate change.
Conventional wisdom says that “early adopters” eventually bring new technologies into the mainstream. Thus, the effort to promote solid state lighting (SSL) has ample historical precedence. Back in the late 70’s, 80’s, and 90’s an epic battle was waged between Video Home System (VHS) and Betamax (Beta). One can draw lessons from the eponymous “videotape format war”—specifically, why technologies catch on (while others fade away)
The U.S. should build 100 more nuclear plants rather than spend "billions in subsidies" for renewable energy if it is truly committed to lowering electric bills and having clean air, the Republicans say. In the party's weekly radio and Internet address, Sen. Lamar Alexander said the United States should follow the example of France, which promoted nuclear power decades ago
Former Vice President Al Gore, a leading voice on climate change, urged lawmakers Friday to overcome partisan differences and pass legislation to curb greenhouse gases. Gore, who won a Nobel prize for his work on global warming, called the climate issue the most important ever before Congress. A Democratic bill limiting carbon dioxide and other pollution linked to a warming of the Earth will simultaneously solve the problems of the climate
