Renewable Energy Marketers Form Trade Association - 0 views

  •  
    (Washington, DC) Some of the most influential and competitive organizations in the renewable energy industry have now joined together to create the first trade association for organizations that market renewable energy. The Renewable Energy Marketers Association (REMA) has formed to vigorously promote the economic and national security benefits of domestic renewable energy.

Top Stories of 2007 - 0 views

    Each year, things seem to get more exciting for the renewable energy industries, and 2007 was no exception. Although there was much disappointment about the exclusion of important provisions for renewables in the recent U.S. energy bill, the overall global picture was positive. With 31 gigawatts of renewable energy developed around the world, 17 billion dollars in global market transactions and 21 billion dollars in global venture capital invested in new companies in 2007, clean energy can no longer be considered an "alternative" -- it is simply the natural evolution of energy.

DOE Loans to Make Nevada the "Saudi Arabia of Geothermal Energy" | Inhabitat ... - 0 views

  •  
    "The Silver State-based company has developed the Faulkner 1, a 49.5 MW geothermal power project at NGP's Blue Mountain site in northwestern Nevada. Currently, the project is planning two new injection wells to enhance the distribution of injected fluids and further augment the plant's power output. As such, the DOE is acting as loan guarantor for up to 80 percent of the $98.5 million loan to NGP for the scheme. As part of the Obama administration's Recovery Act, alternative energy has seen a real increase in investment with projects such as the Cape Wind Farm being finalized. Recent tragedies such as the Gulf of Mexico oil spill have only solidified support for alternative energy. Geothermal projects haven't dominated headlines like solar and wind projects have, but US Senator Harry Reid hopes to see that change. Speaking about the DOE's support, Senator Reid said, "I am glad to see economic recovery funding being used to put Nevadans to work on a project that will help us achieve energy independence" He went on to say, "Northern Nevada is the Saudi Arabia of geothermal energy.""

Peak Energy: The Renewables Hump: Digging Out of a Hole - 0 views

  •  
    Jeff Vail has started a series looking at what I've long called the "EROEI hole" problem - making sure we don't leave the transition to renewables too late and find ourselves stuck in a situation where we have shrinking production of fossil fuels which are produced at ever lower EROEI values, thereby making constructing an alternative energy infrastructure a lot more problematic than it would be today - The Renewables Hump: Digging Out of a Hole. In the first post in this series, I introduced the general notion that renewable energy requires an up-front investment of energy, and that this may dramatically impact our ability to transition to a renewable-energy economy because the transition effort will initially exacerbate the very energy scarcity that is its impetus. Beyond this general notion that the transition to renewables first requires exacerbating our current energy scarcity, the time that it takes a renewable source of energy to return the up-front energy invested in it becomes especially critical. Here's a quick example (for the simplicity of these examples, I'm assuming that 100% of energy requirement is up-front with no maintenance requirement):

Americans Willing To Pay More for Solar | Renewable Energy World - 0 views

  •  
    "A new survey conducted by Applied Materials, Inc. reveals that two-thirds of Americans believe solar technology should play a greater role in meeting the country's energy needs. In addition, three-quarters of Americans feel that increasing renewable energy and decreasing U.S. dependence on foreign oil are the country's top energy priorities. According to the survey, 67 percent of Americans would be willing to pay more for their monthly utility bill if their utility company increased its use of renewable energy and 49 percent of consumers polled would be willing to pay $5 or more each month for an increased amount of renewable energy-a 14 percent increase from the results of Applied Materials' 2009 survey. "Americans are becoming more aware of the need for responsible energy solutions, like solar power, and increasingly want their government to drive policy and investment aimed at finding alternative ways to power our homes and economy," said Dr. Charles Gay, president of Applied Solar, a division of Applied Materials. "With the right energy legislation in place, the U.S. could reap the benefits of one of the biggest economic job engines of this century - the clean energy revolution.""

Renewable Energy Focus - Six renewable energy sources judged to be best prospect for fu... - 1 views

  •  
    The best prospects for large-scale renewable energy production and net-energy performance remain wind and certain forms of solar, according to a study released by two California-based think tanks. "It is reasonable to conclude ... that a full replacement of energy currently derived from fossil fuels with energy from alternative sources is probably impossible over the short term; it may be unrealistic to expect it even over longer time frames," explains Searching for a Miracle: Net Energy Limits & the Fate of Industrial Society. The report was published by the International Forum on Globalization with content provided by the Post Carbon Institute.

Railway Gazette: UltraCaps win out in energy storage - 0 views

  •  
    REGENERATIVE BRAKING is widely practised, but there have to be other trains around to absorb the surplus power being fed back into the catenary or third rail. Processing the output from trains and pushing it back into the local grid is possible with an AC power supply, but very expensive with DC traction. Too often, power produced by traction motors in braking mode ends up heating resistor banks. The elegant alternative is to store the braking energy on the train. This not only avoids the electrical complications of regenerating through the traction power supply network. It reduces the rated power requirement of that network by lopping demand peaks during acceleration, saves energy by reducing losses in the catenary or conductor rail, and by limiting voltage drop it allows substations to be further apart. NiMH batteries have the necessary energy storage density in terms of kWh/kg, and are slightly more expensive, but their life in terms of charge/discharge cycles in no way matches the LRV requirement for 2million cycles over 10 years. Flywheels have been tried but never caught on for several reasons.

The Oil Drum: Europe | Energy Prices, Inflation and Denial - 0 views

  • Higher energy prices are feeding through to rampant consumer energy price inflation. And yet the authorities and many investment houses still see energy prices falling in the future. This naive view of global energy supplies is starving energy markets of the capital required to expand conventional and alternative energy supplies.

  • A molten salt system1 is a means to store thermal energy, thus mitigating the problem of an intermittent source for generating electricity at night or during cloudy weather. It is one of Tom Konrad2’s top ten favorites for an alternative energy future because it’s cheaper to store heat than it is to store electricity and concentrating solar power can produce a ton of heat without pollution or fuel.

Brilliant New Book Teaches You How to Evaluate Sustainable Energy Claims « Jo... - 0 views

  • Unsettlingly, usually, these discussions involve more strong opinions than data. Some people believe that one of these alternative (they are not all sustainable) energy options is the silver bullet that will solve both the climate and the energy crisis. Other argue that there is no silver bullet and that what is required are a variety of silver BB’s: a mixture of technologies, along with greater energy efficiency and preservation of habitat (forests). Do we really just need to build huge number of nuclear plants or wind farms to solve the problem? If, instead, we are going to use a mix of alternative energy sources, which ones should we use and in what quantities?

The American Spectator : A True Energy Policy - 0 views

  •  
    Excellent over view of shale gas and compressed natural gas dynamics including conversion kits for automobiles and truck fleets. THE ONLY LOGICAL ANSWER to bridge the conversion from oil based fuels to paradigm alternatives lies in the conversion of personal transportation to the use of natural gas. Consider the following reasons: (long list) ONE WEEK AFTER Obama's energy policy speech, March 31, 2011, at Georgetown University, a bi-partisan group of more than 150 Members of Congress introduced HR.1835, with Rep. John Sullivan (R-OK) as the primary sponsor. The NAT GAS Act (New Alternative Transportation to Give Americans Solutions) Act, is the culmination of efforts of T. Boone Pickens to promote his "Pickens Plan" for changing the focus of American energy consumption. The NAT GAS Act provides incentives for using natural gas in vehicles, purchasing natural gas vehicles, installing natural gas refueling stations, and producing natural gas vehicles in America. The problem is that Obama and his energy secretary do not actually support HR 1835!  The speech was just a ruse.  Watch what he does, not what he says.  CNG-Compressed Natural Gas

An electric plan for energy resilience - The McKinsey Quarterly - electric plan for ene... - 0 views

  • Our aim should not be total independence from foreign sources of petroleum. That is neither practical nor necessary in a world of interdependent economies. Instead, the objective should be developing a sufficient degree of resilience against disruptions in imports. Think of resilience as the ability to absorb a significant disruption, bigger than what could be managed by drawing down the strategic oil reserve. Our resilience can be strengthened by increasing diversity in the sources of our energy. Commercial, industrial, and home users of oil can already use other sources of energy. By contrast, transportation is totally dependent on petroleum. This is the root cause of our vulnerability. Our goal should be to increase the diversity of energy sources in transportation. The best alternative to oil? Electricity. The means? Convert petroleum-driven miles to electric ones.

Passive Solar Energy - 0 views

  •  
    Solar energy can be utilized in various ways - to provide electricity, mechanical power, heat and lighting. Passive solar heating and cooling can save substantial electricity bills. Design of a building is very important for tapping passive solar energy. The building and windows are designed in such a way that they carefully balance their energy requirements without additional mechanical equipment. Solar benefits are utilized through windows and pumps, and fans are used minimally.

MIT Develops Way to Bank Solar Energy at Home - 0 views

  • During photosynthesis, plants use sunlight to break water into hydrogen and oxygen atoms and later on the atoms recombine and produce energy. MIT scientists have tried to duplicate this method of plants to store sun’s energy.
  • The main constituent in Nocera and Kanan’s procedure is a new catalyst that generates oxygen gas from water and another catalyst produces hydrogen gas. The catalysts are cobalt and platinum. These new catalysts work at normal room temperature in neutral pH water and the whole system can be installed easily.
