Peak Energy: Making the case for wind power - 0 views

  •  
    I must admit that I have been a bit nonplussed to see that the peak oil community seems to share the oil industry's dismissal of wind power as irrelevant and useless in the face of the currently energy challenge (maybe I am unfairly judging from a few individuals' comments, but it's definitely an existing undercurrent in the community). So, in reaction, let me put up here a few arguments that suggest that wind could play a major role in solving our current energy woes - not a silver bullet, but rather more than a side show. First, the "wind is too small to make a difference" argument: well, so was nuclear, until it got big enough. Wind is following the exact same growth trajectory [as shown below].

Newsvine - Climate Change & Australia's water problem... - 0 views

  •  
    Australia is the dryest nation on earth, always was always will be, the trouble is Global warming is making the situation worse and rainfall is reducing in a disturbing pattern. For two centuries since European settlement the States have fought over 'Water-Right's' and the use of water to the detriment of the environment and ultimately to the sustainability of everyone residing here. The Murray-Darling Basin is 3,370km long, drains one-seventh of the Australian land mass, and is currently by far the most significant agricultural area in Australia. The name of the basin is derived from its two major rivers, the Murray River and the Darling River.

The Military-Industrial Complex Embraces Coal-to-Liquids | celsias° - 0 views

  •  
    It is time to pay close attention to President Eisenhower's warning. In the past six months, the U.S. Air Force (USAF) has begun a major effort to define the future of energy supplies for the U.S. and for its military allies. If military brass reach their goal, the transportation fuel of the future will be based on coal. According to Air Force Assistant Secretary William Anderson, the USAF plan is to:

Scottish Company Claims Technology Can Double Vehicles' MPG : TreeHugger - 0 views

  •  
    If electric vehicles aren't your thing, then you may be pleased to hear that at least one company is working on giving that tried and true internal combustion engine a major boost. Artemis, an Edinburgh, Scotland-based company, has developed a hydraulic hybrid transmission that could potentially double the mileage of most vehicles -- by accident, as it happens. The firm's original goal had been to simply reduce CO2 emissions on the highway by 30% (a goal it also achieved).

World Oil - National Geographic Magazine: Tapped Out - 0 views

  •  
    In 2000 a Saudi oil geologist named Sadad I. Al Husseini made a startling discovery. Husseini, then head of exploration and production for the state-owned oil company, Saudi Aramco, had long been skeptical of the oil industry's upbeat forecasts for future production. Since the mid-1990s he had been studying data from the 250 or so major oil fields that produce most of the world's oil. He looked at how much crude remained in each one and how rapidly it was being depleted, then added all the new fields that oil companies hoped to bring on line in coming decades. When he tallied the numbers, Husseini says he realized that many oil experts "were either misreading the global reserves and oil-production data or obfuscating it."

Government Accountability Project: EPA Quietly Releases Climate Change Health Effects R... - 0 views

  •  
    Today, the Environmental Protection Agency (EPA) released a major study by the US Climate Change Science Program synthesizing current scientific knowledge of climate change-induced threats to human health. This information should be critical to the EPA's previous "endangerment finding" for carbon dioxide and other greenhouse gases. However, the EPA Office of Air and Radiation, the branch assigned rulemaking responsibility, evidently did not rely on and did not cite the CCSP report.

The Associated Press: Cheney reportedly wanted cuts in climate testimony - 0 views

  •  
    Vice President Dick Cheney's office pushed for major deletions in congressional testimony on the public health consequences of climate change, fearing the presentation by a leading health official might make it harder to avoid regulating greenhouse gases, a former EPA officials maintains. When six pages were cut from testimony on climate change and public health by the head of the Centers for Disease Control and Prevention last October, the White House insisted the changes were made because of reservations raised by White House advisers about the accuracy of the science.

    Integrating solar cells into building materials could make solar power more attractive to homeowners. Seamless solar: The solar system shown here (darker panels) integrates thin-film solar modules directly into a metal roof. Such systems offer cost savings in labor and materials and blend well with buildings' designs. Credit: EnergyPeak In an effort to promote the adoption of solar technology, United Solar Ovonic of Auburn Hills, MI, has teamed with a major roofing company to create a metal roof system that generates electricity from sunlight. The partnership offers seven different prefabricated systems, ranging in capacity from 3 to 120 kilowatts. Tests show that the solar roof panels are rugged and can withstand winds in excess of 160 miles per hour.

Coal Company to Blow Up Major West Virginia Wind Power Resource : Red, Green, and Blue - 0 views

  •  
    In a high profile campaign, West Virginia citizens have asked for a last minute 'stay of execution' against the imminent destruction of the site of a proposed wind farm on the state's Coal River Mountain. Handing in a petition, signed by more than 8,000 residents, campaigners today called on State Governor Minchin to make good on his commitment to support the development of renewable energy in the state, and order a halt to the destruction of an area with enough wind power potential to supply 150,000 homes.

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.

Energy Reliant States - 0 views

  •  
    How much energy could be generated by states tapping into internal renewable resources? To date, no study has addressed this question comprehensively. This report is a first attempt to do so. The data in this report, while preliminary, suggest that at least half of the fifty states could meet all their internal energy needs from renewable energy generated inside their borders, and the vast majority could meet a significant percentage. And these estimates may well be conservative.

Hydrogen plan will fill in when wind turbines stop - Scotsman.com News - 0 views

  •  
    A MAJOR criticism of wind farms is that they are intermittent. Wind does not blow consistently and, as a result they do not provide a continuous supply of power, but must be backed up by conventional fossil fuel plants. However, a renewables firm believes it has hit on a solution, and is hoping to use it in Scotland. A hydrogen plant would store energy from the wind farm, creating a reserve that could be dipped into on demand, so that even when the wind was not blowing, an electricity supply would be available.

The five reasons for an energy-efficient stimulus - 0 views

  •  
    As President-elect Barack Obama prepares to tackle the vast problems ahead for America, he has consistently made two bold proposals. First, he intends to make an immense investment in infrastructure - roads, bridges, railways - to jump-start jobs. Second, he plans to boost clean green technologies to make up for the squandered opportunities of the Lost Decade. These are both powerful, worthy ideas. But they would be far more powerful if they were directly connected. The incoming administration has a historic opportunity to accomplish five major goals at once through a massive investment in stopping the waste of energy and dollars pouring out of American homes.

Pittsburgh Councilman's plan to convert all of the city's street lamps to LEDs could sa... - 0 views

  •  
    Earlier today I received an email from the office of Pittsburgh city councilman Bill Peduto announcing an ambitious plan that will reduce Pittsburgh's carbon footprint while saving the city millions in electricity costs. Peduto, who has been the only city legislator to propose green legislation of any sort over the last few years, wants the city to convert all 40,000 of its street lamps to energy efficient LED lighting. The cost of the program will be around $24 million and will be paid using a combination of the annual costs savings and funding from the state's Guaranteed Energy Savings Agreement. Pittsburgh would join cities such as Austin, Raleigh (home LED manufacturer CREE), and Toronto as major cities who have adopted LED lighting on a large scale. According to Peduto, Pittsburgh would be the largest city in the US to roll out a complete conversion to LED lighting. This would be great news for Pittsburgh's green agenda, especially in light of today's Pittsburgh Penguin's press conference, where they announced the 21 year naming rights deal for their new arena, which will be known as the Clean Coal Center.

Good news for wind, bad for ethanol in major energy study - 0 views

  •  
    Growing concerns over climate change and energy security have kicked research on alternative energy sources into high gear. The list of options continues to expand, yet few papers have comprehensively reviewed them. And fewer still have weighed the pros and cons in as much depth as a new study published earlier this month in the journal, Energy & Environmental Science. The results are a mixed bag of logical conclusions and startling wake-up calls. The review pits twelve combinations of electric power generation and vehicular motivation against each other. It is a battle royal of nine electric power sources, three vehicle technologies, and two liquid fuel sources. It rates each combination based on eleven categories. And it was all compiled by one man, Mark Jacobson, professor of civil and environmental engineering at Stanford University.

Energy from the wind is the best for Earth | Emerging Technology Trends | ZDNet.com - 0 views

  •  
    According to a Stanford University researcher, 'wind, water and sun beat biofuels, nuclear and coal for clean energy.' The scientist 'has conducted the first quantitative, scientific evaluation of the proposed, major, energy-related solutions by assessing not only their potential for delivering energy for electricity and vehicles, but also their impacts on global warming, human health, energy security, water supply, space requirements, wildlife, water pollution, reliability and sustainability.' Wow! The researcher found that some sources of energy were 25 to 1,000 times more polluting than the best available options. Some of his conclusions make sense, some are controversial, but read more…

Solar panel industry achieves Holy Grail - $1 per watt grid-parity - 0 views

  •  
    March 3, 2009 Arizona based First Solar has achieved a major milestone in reducing the manufacturing cost for solar panels below the $1 per watt price barrier - the target necessary for solar to compete with coal-burning electricity on the grid or grid-parity. Using cadmium telluride (CdTe) technology in its thin-film photovoltaic cells, First Solar claims to have the lowest manufacturing cost per watt in the industry with the ability to make solar cells at 98 cents per watt, one third of the price of comparable standard silicon panels. The efficiency is in part due to a low cycle time - 2.5 hours from sheet of glass to solar module - about a tenth of the time it takes for silicon equivalents.
