Peak Energy: Cutting Coal Use with Solar Thermal Power - 0 views

  •  
    Technology Review reports that the idea of hybrid gas-solar thermal power plants is being considered for coal fired plants now - Cutting Coal Use with Sunshine. Feeding heat from the sun into coal-fired power stations could turn out to be the cheapest way to simultaneously expand the use of solar energy and trim coal plants' oversize carbon footprints. At least that's what the Electric Power Research Institute (EPRI), a nonprofit organization backed by the electricity industry, is hoping. Last week, the institute launched a nine-month, $640,000 study to pin down the scale of the opportunity and the engineering challenges involved with making these seemingly disparate technologies work together. The study will examine the potential use of solar-thermal technology at a pair of coal-fired power stations, in New Mexico and North Carolina.

Red, Green, and Blue: Colorado to Ditch Two Coal Plants, Moving to Solar and Wind - 0 views

  •  
    State regulators in Colorado have given the green light to plans by Xcel Energy to shut down two coal-powered energy plants in the state, and build one of the world's largest utility-scale solar-power facilities. Following discussions lasting several days, the Colorado Public Utilities Commission (CPUC) backed the power company's voluntary decision to close the two coal-fired plants at Denver and Grand Junction, making Xcel the first utility in the U.S. to make such a move solely in an effort to reduce emissions.

George Monbiot: The stakes could not be higher. Everything hinges on stopping coal | Co... - 0 views

  •  
    As soon as I have finished this column I will jump on the train to Kent. Last year Al Gore remarked: "I can't understand why there aren't rings of young people blocking bulldozers and preventing them from constructing coal-fired power plants." Like hundreds of honorary young people, I am casting my Zimmer frame aside to answer the call. Everything now hinges on stopping coal. Whether we prevent runaway climate change largely depends on whether we keep using the most carbon-intensive fossil fuel. Unless we either leave it - or the carbon dioxide it produces - in the ground, human development will start spiralling backwards. The more coal is burnt, the smaller are our chances of future comfort and prosperity. The industrial revolution has gone into reverse.

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.

Solar power a strong contender (ScienceAlert) - 0 views

  •  
    Kramer Junction. Nevada Solar One. Andasol 1. Kimberlina. They're obscure names today. But they'll be household names tomorrow. The reason? Each is now providing 'here and now' proof concentrating solar power (CSP) works. That can't be said for cabon capture and storage. Nor can it be said for 'next generation' nuclear. Each faces years of additional research and development before some 'first mover' will be game enough to build one. That just isn't the case with concentrating solar power. It's got 20 years of proven commercial operation (Kramer Junction) behind it. It also has new innovations coming on line (Nevada Solar One), with solar thermal storage (Andasol 1), and the promise of super-low costs in coming years (Ausra's Kimberlina). What it adds up to is a price-declining research and development juggernaut in concentrating solar power. This is rapidly bringing concentrating solar power closer to competitiveness with dirty fossil fuels. The California Energy Commission estimates this price 'cross over' could happen by 2015. Bulls predict sooner. And in an industry where new plants and equipment can last 40 years, 5-7 years from now is like tomorrow. What this means is that for forward planning of new infrastructure, concentrating solar power is already nipping at the heels of coal. Toss in carbon prices and the reduced likelihood of protesters chaining themselves to bulldozers as they are likely to at any new coal plants, CSP starts looking like a VERY good deal indeed.

The Charleston Gazette - - 'Clean coal' policies absent, GAO finds - 0 views

  •  
    Federal policy-makers have taken few of the steps necessary if greenhouse emissions from coal-fired power plants are to be captured and stored underground, according to a new government report. Coal industry backers are banking that "carbon capture and storage" will allow the industry to survive efforts to control global climate change. But the U.S. Government Accountability Office report, released this week, adds to growing concerns that the technology isn't ready now - and might not be for a long time.

Greenpeace energy report projects cheap, clean power -- and more jobs | Greenspace | Lo... - 0 views

  •  
    An environmentalist-sponsored report claims that by 2050, the United States could sever ties with coal and nuclear power, draw nearly all its electricity from renewable sources and cut its greenhouse gas emissions by more than 80% -- all with existing technology and with a net gain of 14 million jobs to the domestic economy. The report, commissioned by Greenpeace and the European Renewable Energy Council and conducted by Germany's equivalent of NASA, was released this morning at a press briefing in Washington. It is heavy on charts and supporting data and transparent on some key assumptions. And its sponsors call its findings "conservative." At its core, the report envisions a steep drop in the United States' energy use, both in absolute terms and compared with International Energy Agency predictions -- driven by strict efficiency standards. It also projects dramatic changes in the nation's electricity mix, with wind and solar power mushrooming to replace coal, oil and nuclear sources that would gradually go offline.

Peak Energy: Energy 101: Where Does Our Power Come From ? - 0 views

  •  
    Inhabitat is doing a "Energy 101" series to explain why smart grids are necessary - Energy 101: Where Does Our Power Come From ?. Today we're excited to announce the launch of our new Energy 101 series,. in which we'll be exploring the future-forward technologies that stand to upgrade our grids, reduce our energy footprint, and slow the speed of global warming. Unless you have been living in a cave for the past few years, you've probably heard terms like "energy conservation", "off-grid energy", and "smart grid" tossed around. But before getting into the nitty-gritty of transitioning to renewable energy, we should stop and examine where exactly our power comes from now. Unless you derive all your power from on-site renewable energy sources like solar panels or wind turbines, chances are that you're connected to the power grid, a vast network that delivers electricity from suppliers to consumers. Right now, most energy on the grid comes from generating plants. These plants still usually get power from traditional sources like coal, nuclear, and hydroelectric dams. But as concerns over carbon emissions, safety, and long term sustainability of these sources grow, electrical utilities have begun to switch over to renewable energy sources.

World Geothermal Power Generation Nearing Eruption - 0 views

  •  
    With fossil fuel prices escalating and countries searching for ways to reduce oil dependence and greenhouse gas emissions, capturing the earth's heat for power generation is garnering new attention. First begun in Larderello, Italy, in 1904, electricity generation using geothermal energy is now taking place in 24 countries, 5 of which use it to produce 15 percent or more of their total electricity. In the first half of 2008, total world installed geothermal power capacity passed 10,000 megawatts and now produces enough electricity to meet the needs of 60 million people, roughly the population of the United Kingdom. In 2010, capacity could increase to 13,500 megawatts across 46 countries-equivalent to 27 coal-fired power plants.

Top 7 alternative energies listed: ENN - 0 views

  •  
    The US could replace all its cars and trucks with electric cars powered by wind turbines taking up less than 3 square kilometres - in theory, at least. That's the conclusion of a detailed study ranking 11 types of non-fossil fuels according to their total ecological footprint and their benefit to human health. The study, carried out by Mark Jacobson of the atmosphere and energy programme at Stanford University, found wind power to be by far the most desirable source of energy. Biofuels from corn and plant waste came right at the bottom of the list, along with nuclear power and "clean" coal.
