Peak Energy: Low Temperature Geothermal Power - 0 views

  •  
    The ABC recently had a report on plans to power north-west Queensland with low temperature geothermal power using hot water from the Great Artesian Basin. A Brisbane-based company says it could supply geothermal power to all of north-west Queensland. Clean Energy Australasia wants to build a $50 million geothermal power station near Longreach. But it has now also revealed plans to build a pilot geothermal project near BHP's Cannington mine at McKinlay, south of Cloncurry. The company's Joe Reichman says the Mount Isa region needs about 500 megawatts of power a year and geothermal resources could easily provide that. "It'll change the region into a powerhouse," he said. Mr Reichman says the company has applied for federal and state government grants and has support from the major mining companies in the region. If the projects proceed they would be the first geothermal power plants in Australia.

Startup Turns CO2 Into Fuel | Autopia from Wired.com - 0 views

  •  
    Researchers developing alternatives to fossil fuels are working with everything from algae to babassu oil to corn, but a California company says it can recycle carbon dioxide into fuel. Carbon Sciences claims it has developed a way of using the CO2 emitted during the combustion of coal, oil and other hydrocarbons to create transportation fuels like gasoline and jet fuel. Should Carbon Sciences - or any of the other firms working on similar projects - accomplish this on a large scale, it could bring a reduction in CO2 emissions as well as an abundant supply of renewable fuel.

Peak Energy: Better Wind Turbines - 0 views

  •  
    Technology Review has an article on advances in wind turbine technology - Better Wind Turbines. ExRo Technologies, a startup based in Vancouver, BC, has developed a new kind of generator that's well suited to harvesting energy from wind. It could lower the cost of wind turbines while increasing their power output by 50 percent. The new generator runs efficiently over a wider range of conditions than conventional generators do. When the shaft running through an ordinary generator is turning at the optimal rate, more than 90 percent of its energy can be converted into electricity. But if it speeds up or slows down, the generator's efficiency drops dramatically. This isn't a problem in conventional power plants, where the turbines turn at a steady rate, fed by a constant supply of energy from coal or some other fuel. But wind speed can vary wildly. Turbine blades that change pitch to catch more or less wind can help, as can transmissions that mediate between the spinning blades and the generator shaft. But transmissions add both manufacturing and maintenance costs, and there's a limit to how much changing the blade angle can compensate for changing winds.

Geothermal Electricity Booming in Germany - 0 views

  •  
    Electricity from geothermal sources is set to soar in Germany -- and all thanks to a law that has made drilling wells deep enough to hit the hot temperature water, which is needed to produce electricity, financially viable. Less than 0.4 percent of Germany's total primary energy supply came from geothermal sources in 2004. But after a renewable energy law that introduced a tariff scheme of EU €0.15 [US $0.23] per kilowatt-hour (kWh) for electricity produced from geothermal sources came into effect that year, a construction boom was sparked and the new power plants are now starting to come online.

Our Electric Future - The American, A Magazine of Ideas - 0 views

  •  
    Twenty-five years ago, when I was CEO of Intel, I had an unusual experience while visiting a customer. It was during a period of tight availability of microprocessors, our main product. This was not an unusual state of affairs. Supply and demand ebbed and flowed as the computer business had its ups and downs. Sometimes we had too many chips sitting in inventory; other times, like this one, we had too few. My main purpose in visiting was to reassure the customer that we were working hard to boost production and that relief was on the way.

Wind overtakes water in Britain's green energy mix | Environment | Reuters - 0 views

  •  
    Wind supplied more of Britain's electricity that water for the first time last year, while power generators preferred gas to coal and nuclear output continued to decline, according to new government data. Five percent of Britain's electricity came from renewable sources in 2007, up from 4.6 percent in 2006, as more wind farms started feeding clean electricity into the network, helping cut the country's carbon emissions.

Pickens on his energy plan - Los Angeles Times - 0 views

  •  
    Last week, Pickens stopped by The Times to discuss his push to wean the U.S. off foreign oil by dramatically ramping up development of its infrastructure for wind and natural gas. Below is a partial transcript. T. Boone Pickens: We are now importing oil that costs us $700 billion a year. That's four and a half times what the Iraq war costs. Nobody running for president even speaks about this. Yet they talk a lot about the Iraq war. When you look at it, the world oil supply is about 85 million barrels of oil a day. And demand is about 86-plus million barrels a day.

    BPA - Elliot Mainzer takes the key role in developing energy agency policy on climate change, planning and renewables As renewable energy becomes a bigger slice of the Northwest's energy pie, few institutions have as important a role to play as the Bonneville Power Administration, the federal agency that markets electricity generated at 31 dams and a nuclear plant in the region. BPA's regionwide web of transmission lines delivers electrons generated at wind farms east of the Cascades to power-hungry consumers in the Willamette Valley. The agency's flexibility to modulate electricity production at dams on the Columbia allows utilities to safely feed their spiky supply of wind energy onto the grid.

    Chemists claim that by mimicking photosynthesis in the lab, they could revolutionize fuel production within five years. Katharine Sanderson reports. Dan Nocera, a chemist at the Massachusetts Institute of Technology (MIT), Cambridge, made a bold statement at the American Chemical Society's fall meeting in Philadelphia last month. He claimed that within five years he could build a device capable of producing locally sourced hydrogen gas, which could power all the world's houses, fill people's car batteries and revolutionize energy supply in the developing world. "I guarantee, in under five years, you'll see this," he said.

Oil and gas exploration all the rage on Capitol Hill | Business | Chron.com - Houston C... - 0 views

  •  
    Drill, drill, drill. Suddenly, oil and gas exploration is all the rage on Capitol Hill. With energy prices a red-hot political issue, the Democratic-controlled Congress, in the midst of its final, three-week legislative sprint before the presidential elections, can't get enough of drilling bills. Not that most Capitol Hill watchers seriously believe that - in the absence of a major supply disruption - any substantive energy legislation will actually emerge from this frenzy and become law. "You don't pass energy bills in the heat of the campaign season," noted Frank Maisano, an energy specialist with Bracewell & Giuliani. Still, there should be plenty of action.

The Car that Runs on Air and Magnets | Environmental Graffiti - 0 views

  •  
    With fuel prices rising and supplies dwindling, more and more inventors are turning their creativity towards cars that work without the need for barrels of gasoline. True, there have been a number of vehicles released that run on electricity but now designers are turning to another precious resource - air. It's not a new concept, as early as the 1920s, car designers were dabbling with the idea of cars that could run off air alone - one involved cycling air through a propeller at the front of the car - but few came to fruition. Now, designers are again looking at how air can be used to power a car.

Peak Energy: Project Get Ready Aims to Create Electric Vehicle Revolution - 0 views

  •  
    WorldChanging has a post on a Rocky Mountain Institute backed initiative to pave the way fro smart grids and electric vehicles - Project Get Ready Aims to Create Electric Vehicle Revolution. Creating a well functioning smart grid - cyclically connected to smart vehicles and buildings and houses, as well as personal and public renewable energy systems - will be no small infrastructure feat. Utility providers, technology innovators, neighborhood councils and local governments will need to come together to provide needed support -- both monetarily and ideologically. Although U.S. President Obama and the recently passed stimulus plan are pushing the renewable, electric energy revolution forward, residents across the nation might need more motivation to make the leap from fossil fuel users to plug-in pioneers. A new project, headed by "think-and-do" tank the Rocky Mountain Institute, is offering to help city leaders provide community members with that extra inspiration. The initiative, Project Get Ready, supplies a menu of strategies that are meant to help cities prepare for the "plug-in" transition. According to RMI, problems related to individual hesitancy toward purchasing electric vehicles and investing in the infrastructure itself, can "be overcome if cities/regions become ecosystems that welcome electric vehicles."

Electricity systems can cope with large-scale wind power: ENN - 0 views

  •  
    Research by TU Delft proves that Dutch power stations are able to cope at any time in the future with variations in demand for electricity and supply of wind power, as long as use is made of up-to-date wind forecasts. PhD candidate Bart Ummels also demonstrates that there is no need for energy storage facilities. Ummels will receive his PhD on this topic on Thursday 26 February. Wind is variable and can only partially be predicted. The large-scale use of wind power in the electricity system is therefore tricky. PhD candidate Bart Ummels MSc. investigated the consequences of using a substantial amount of wind power within the Dutch electricity system. He used simulation models, such as those developed by Dutch transmission system operator TenneT, to pinpoint potential problems (and solutions).

Peak Energy: A buoyant future in wave power - 0 views

  •  
    Reuters has a report on Australian wave power company Carnegie Corp and the vast potential for wave power in southern Australia - Aussie firm sees buoyant future in wave power. For millennia, Australia's rugged southern coast has been carved by the relentless action of waves crashing ashore. The same wave energy could soon be harnessed to power towns and cities and trim Australia's carbon emissions. "Waves are already concentrated solar energy," says Michael Ottaviano, who leads a Western Australian firm developing a method to turn wave power into electricity. "The earth has been heated by the Sun, creating wind, which created the swells," he told Reuters from Perth, saying wave power had the potential to supply all of Australia's needs many times over.

    DOVER, Mass. - On a recent sunny afternoon Bob Loebelenz pauses to gaze 72 feet into the air at the spinning blades of his wind turbine, a small "clean, free electricity" smile creasing the corners of his mouth. While giant wind turbines that supply power to utilities sprout along ridgelines across the United States, far smaller residential wind generators, like the one Mr. Loebelenz erected in 2003 to power his suburban Boston home, are still unusual in densely populated places.
