2006 Wind Installations Offset More Than 40 Million Tons of CO2 | Worldwatch Institute - 0 views

  •  
    The 15,200 megawatts of new wind turbines installed worldwide last year will generate enough clean electricity annually to offset the carbon dioxide emissions of 23 average-sized U.S. coal-fired power plants, according to a new Vital Signs Update from the Worldwatch Institute.[1] The 43 million tons of carbon dioxide displaced in 2006 is equivalent to the emissions of 7,200 megawatts of coal-fired power plants, or nearly 8 million passenger cars.

Jevons' Paradox and the Perils of Efficient Energy Use | Aerotropolis | Fast Company - 1 views

  • The engine of coal's demise would be the same invention that was created to conserve it: the steam engine. But it made burning coal so efficient, that instead of conserving coal, it drove the price down until everyone was burning it. This is Jevons' Paradox: the more efficiently you use a resource, the more of it you will use. Put another way: the better the machine--or fuel--the broader its adoption.

Electricity | Pew Center on Global Climate Change - 3 views

  •  
    The electricity sector accounts for almost 35 percent of greenhouse gas (GHG) emissions in the United States, and 40 percent of the carbon dioxide (CO2) emissions. Over 80 percent of GHG emissions associated with electricity generation are from the combustion of coal, with nearly all the rest due to natural gas and petroleum combustion. U.S. electricity sales are split among the residential (37 percent), commercial (36 percent), and industrial (27 percent) sectors, where primary uses vary by sector. Over the past 30 years the U.S. electricity sector has become less carbon intensive, and the U.S. economy has grown less electricity-intensive.

IGCC's Future Hinges on Workable Carbon Framework - 0 views

  • One of the leading alternatives for producing clean power from coal -- Integrated Combined Cycle Gasification (IGCC) technology faces a precarious future due to rising capital costs and regulatory uncertainty. A process of gasifying coal that allows capture of carbon dioxide emissions, IGCC has tremendous potential for meeting future baseload generation demand but project momentum has slowed dramatically in 2007, according to a new study from Emerging Energy Research (EER). Despite delays or cancellations of several prominent IGCC projects in 2007, 48 projects with a combined capacity of over 25,000 MW remain in the global IGCC pipeline, according to EER.

GE, Idaho Labs turn waste heat into electricity | Green Tech - CNET News - 0 views

  •  
    Rather than use a working fluid to capture and transfer the waste heat, GE has developed a new evaporator to transfer it. The new design means that ORCs can be used to convert relatively low-temperature heat (under 500 degrees Celsius) into electricity on a wide range of power sources, including the equipment in coal power plants and small gas turbines, said Thomas Fry, a researcher in GE's Munich offices.

energy ring best option to solve regional needs - March 15, 2012 - Power Eengineer - Tr... - 1 views

  • Recent reports in the media suggest that India, Pakistan, Bangladesh, Nepal and Bhutan import anything between 75% and 100% of their respective domestic requirements for petroleum. The region is otherwise rich in other sources of energy which are not evenly distributed and to a large extent untapped. India, Pakistan and Bangladesh have large reserves of gas and coal. The entire region has among the world's highest potential for hydro-electric power, with Nepal and Bhutan in the lead. There exists a high potential for renewable energy, with India showing the way in solar and wind energy. Sri Lanka is looking to leverage hydro-electricity and biomass resources for its energy needs.

Could Cheap Natural Gas Slow Growth Of Renewable Energy? : NPR - 0 views

  • The boom in cheap natural gas in this country is good news for the environment, because relatively clean gas is replacing dirty coal-fired power plants. But in the long run, cheap natural gas could slow the growth of even cleaner sources of energy, such as wind and solar power.

Resource Insights: Fossil Fuels vs. Renewables: The Key Argument that Environmentalists... - 0 views

  • It turns out, however, that what most environmentalists know about the future supply of natural gas and other fossil fuels is based more on industry hype than on actual data. And, that means that they are missing a key argument in their discussions about renewable energy, one that could be used to persuade those less concerned about pollution and climate change and more concerned about energy security: There is increasing evidence that no fossil fuel will continue to see its rate of production climb significantly in the decades ahead and so none of them is a viable "bridge fuel," not natural gas, not oil, not coal. This means that global society must leap over fossil fuels and move directly to renewables as quickly as possible. In advanced economies this leap must be combined with a program of radical reductions in energy use, reductions which are achievable using known technologies and practices.

Opinion | Nuclear cleanup regulation could put public at risk | Seattle Times Newspaper - 0 views

  •  
    "The weaknesses of federal regulatory agencies have been exposed by recent high-profile accidents. Guest columnist Tom Carpenter fears the Department of Energy will reduce its oversight of cleanup at the nation's nuclear waste sites. By Tom Carpenter Special to The Times PREV of NEXT Related Millions of gallons of oil gush continue to rush unabated from BP's mile-deep well in the Gulf of Mexico, and 11 workers are dead from the massive explosion that caused the biggest oil spill in decades. Weeks before this event, the news was dominated by the preventable explosion that killed 29 West Virginia coal miners. In both cases, the not-so surprising news was that the mine and the oil rig had abysmal records of safety violations before the explosions yet were still allowed to operate by the captive regulatory agencies. Where is the government accountability? It is the government's job to assure that ultra-hazardous industries operate safely and responsibly. Is nuclear next? The Department of Energy sits on the nation's biggest nuclear nightmare. Its inventories of highly radioactive and toxic wastes defy comprehension. Washingtonians are familiar with the DOE's No. 1 accomplishment, the Hanford nuclear site, which holds the lion's share of the nation's radioactive detritus. Suffice it to say that the escape of even a small fraction of such material into the environment would constitute a Chernobyl-sized catastrophe."

Amory Lovins on the Transition to Renewables & How They Enhance Security and Sustai... - 1 views

  •  
    "In the wake of the BP Gulf oil disaster, the natural gas explosion in Texas this month and the coal mine diaster earlier this year. It seems like public consciousness is finally shifting. While being green and supporting renewable energy was a good public relations move for the last few years, it now seems like a practical one as well to prevent disasters like these from occurring again. It seems like the mood is ripe for the transition to renewables and other sustainable energy technologies to begin in earnest. I had the chance to sit down with Dr. Amory Lovins, chief scientist and co-founder of the Rocky Mountain Institute, to talk about how the transition to renewables will make the U.S. energy system more secure and stable and where the country currently stands in that process."

Germany's Solar Cell Promotion: Dark Clouds on the Horizon | Leonardo ENERGY - 0 views

  • This article demonstrates that the large feed-in tariffs currently guaranteed for solar electricity in Germany constitute a subsidization regime that, if extended to 2020, threatens to reach a level comparable to that of German hard coal production, a notoriously outstanding example of misguided political intervention. Yet, as a consequence of the coexistence of the German Renewable Energy Sources Act (EEG) and theEUEmissions Trading Scheme (ETS), the increased use of renewable energy technologies does not imply any additional emission reductions beyond those already achieved by ETS alone. Similarly disappointing is the net employment balance, which is likely to be negative if one takes into account the opportunity cost of this form of solar photovoltaic support. Along the lines of the International Energy Agency (IEA 2007:77), we therefore recommend the immediate and drastic reduction of the magnitude of the feed-in tariffs granted for solar-based electricity. Ultimately, producing electricity on this basis is among the most expensive greenhouse gas abatement options.

Giving serious consideration to compressed-air energy storage - 0 views

  •  
    My Clean Break column today is actually more of a feature looking at compressed-air energy storage (CAES) and how Ontario, geologically, would be an excellent location to give it a try. About 50,000 natural gas and oil wells have been drilled in southwestern Ontario over the past 150 years and most of them are depleted. Turns out that depleted gas fields are one of several types of underground reservoir that can be used to store compressed air. Salt caverns are another option, and we have plenty of those as well. In fact, 60 per cent of Canada's natural gas storage is in the region. Compressing and storing air wouldn't be that different technically. Another benefit is that southwestern Ontario has strong wind resources, so building a 1,000 MW-plus CAES facility on its own or as part of a partnership with area wind developers could prove quite economical. The idea, of course, is that cheap wind power generated overnight when demand is down could be used to compress and store the air. The air could then be released to generate electricity during daytime peaks, making wind a dispatchable resource in Ontario and more of a realistic replacement for coal power as it gets phased out of the province. Surplus overnight nuclear power, when we have it (mostly during the summer), could also be stored this way.

YouTube - Gapcast #10 - Carbon Dioxide - 0 views

  • Everyone contributes to carbon dioxide emissions, but some more than others. Reducing global CO2 emissions requires that we have a good understanding of the current picture. Serious progress can be made if we develop a renewable source of electricity that is cheaper than coal.
