The Energy Blog: Brighter LED Lights Could Replace Household Light Bulbs Within Three Y... - 0 views

  • Light Emitting Diodes (LEDs), already used in electrical equipment such as computers and mobile phones, are several times more energy efficient than standard light-bulbs. However, because of their structure and material, much of the light in standard LEDs becomes trapped, reducing the brightness of the light and making them unsuitable as the main lighting source in the home.

DOE Tightens Efficiency Standards for Utility Transformers - 0 views

  • The rule specifically applies to liquid-immersed transformers and medium-voltage, dry-type transformers. Utility transformers are already extremely efficient at delivering energy with minimal losses, but because they handle large amounts of electricity, small gains in efficiency can yield large energy savings. According to the published rule, the new rule could raise the cost of liquid-immersed transformers by up to 12%, but should decrease electrical losses by as much as 23%. It could also raise the cost of medium-voltage, dry-type transformers by up to 13%, but should decrease electrical losses by as much as 26%.

Energy Efficiency of Induction Machines: A Critical Assessment - 0 views

  • In this work, some fundamental aspects concerning the efficiency of induction machines are treated. The standards and the therein prescribed methods for the determination of the energy efficiency of induction machines are discussed. A detailed comparison of the four most relevant and recent methods identifies the differences. By means of measurement results of different machines, the differences between and the shortcomings of certain methods is confirmed. In that context, special attention is paid to the new, so-called ‘Eh-Y’ method. A concise overview of the most important points of attention for an increased efficiency of motor drives en the role of the induction motor (efficiency) in this context is completed with some examples. The difference between motor and generator mode is discussed and explained based on measurement results of machines of different size and efficiency class. Special attention is paid to the behaviour and performance of induction machines supplied by unbalanced voltages. More specifically it is investigated if and how the susceptibility to voltage asymmetry is influenced by material choice, in which the main focus lies on copper rotor technology. Therefore, the different standards for the description and quantification of voltage unbalance are studied first. The theoretical discussion is backed-up with experimental results of several machines.

IBM: Firms want to be responsible, but lack proper data - 0 views

  •  
    The IBM survey found that only 30 per cent of respondents' firms are collecting data frequently enough to make strategic decisions that address inefficiencies across eight major categories: carbon dioxide, water, waste, energy, sustainable procurement, labor standards, product composition and product lifecycle. Twenty-four percent collect this information monthly, while another 32 per cent do so no more than quarterly.

Cooking - gas or electric - 0 views

  •  
    Among the major culprits here are inefficient appliances. According to the United States Department of Energy, a gas burner delivers only 35 to 40 percent of its heat energy to the pan; a standard electrical element conveys about 70 percent. Anyone thinking about kitchen renovation should know that induction cooktops, which generate heat directly within the pan itself, are around 90 percent efficient.

UL Environment To Test Consumer Tech Energy Efficiency Claims | EarthTechling - 1 views

  • This new certification program, according to UL Environment, will be called Energy Efficiency Certification (EEC). It will test consumer focused items, including appliances, heating, air conditioning and refrigeration systems, high tech equipment, and lighting products, against energy efficiency standards and regulations like Energy Star, Natural Resources Canada (NRCan) and California Energy Commission (CEC). Those products which are proven to meet these standards will get yet another shiny label to put on product packaging – UL Environment’s leaf encapsulating the familiar “UL” initials and including the words “Energy Verified” in black text.

    Charles Bremner, Times, UK offers up some great news for air travelers. The dream of inexpensive, ecofriendly aviation has come closer to reality after a French test pilot achieved the first flight in a conventional light aircraft powered by an electric motor. The Electra, a wood-and-fabric single-seater, flew for 48 minutes for 50km (30 miles) around the southern Alps, winning a global race to apply battery power to a fixed-wing standard aircraft….Electric power for larger aircraft, including airliners, is also on the horizon, with research by Nasa and Boeing into the holy grail of the field: hydrogen-fed fuel cells. These will drive electric motors with power like those on French high-speed trains.

Guest Commentary: Can the growth of renewable energy be sustained? - The Denver Post - 0 views

  • Colorado's renewable energy standard has in many respects been among the more successful ones in the country. But, between the pending expiration of production tax credits for wind energy and the fact that Colorado's dominant utility has already acquired sufficient renewable resources to meet its obligation of 30 percent renewables by 2020, there is concern over whether the growth in renewable energy in Colorado can be sustained.

Cotter corp. starts water cleanup in old uranium mine - The Denver Post - 0 views

  •  
    "The owner of a defunct uranium mine leaking pollution along a creek that flows into a Denver Water reservoir has launched a cleanup as ordered, state officials confirmed Thursday. Cotter Corp. installed a system that can pump and treat up to 50 gallons per minute of contaminated water from inside its Schwartzenwalder Mine, west of Denver in Jefferson County. Water tests in 2007 recorded uranium levels in mine water exceeding the human health standard by 1,000 times. Elevated levels in Ralston Creek also were recorded. The Colorado Department of Public Health and Environment ordered the action. State natural-resources officials also are monitoring the mine, which produced uranium for weapons and nuclear power plants."

Over a Third of Power from New Energy - Study | NewEnergyNews - 0 views

  •  
    "t is a crucial, if geekish, point: Wind and solar power are NOT intermittent, they are VARIABLE. If someone talks about problems with the intermittencies of wind and solar energies, it is out of ignorance or to intentionally discredit them. Obviously, the sun does not always shine and the wind does not always blow but those things can be scheduled and forecasted and are no reasons whatsoever not to keep building wind power and solar energy as fast as is humanly possible. The Western Wind and Solar Integration Study, from the National Renewable Energy Laboratory (NREL) of the U.S. Department of Energy (DOE), says transmission system tools are now available that would allow the Mountain West and Southwestern states to get 35% of their electricity from wind and solar energies by 2017. All it will require, aside from the building of the wind and solar production capacity, is a change in the WestConnect group of grid operators' standard operating procedures."

Worldchanging: Bright Green: A New, Bold Plan for a Carbon-Neutral UK by 2030 - 0 views

  •  
    "Carbon neutrality by 2030 is the new standard for climate policies, and again the UK is leading North America in the climate debate with a bold national-level proposal about how to get there. The Centre for Alternative Technology just launched zerocarbonbritain2030 (ZCB2030), a collaborative project showing one possible scenario for making the entire UK carbon-neutral by 2030. ZCB2030 is a well-researched, well-written, and well-designed report on a set of possible pathways to a zero carbon Britain by 2030 (The goal, though bold, is not unique: Alex Steffen called for a very similar position for Seattle, a target which the Seattle City Council has included in their legislative priorities this year; and a variety of other nations and cities are approaching the same target, from Copenhagen to New Zealand). In 384 pages, CAT presents a comprehensive look at the kind of systemic changes needed to achieve dramatic emissions reduction in just 20 years in such areas as farming, energy generation, building codes, transportation planning, and economic frameworks. This report truly addresses the scope, scale and speed of the climate crisis and the solutions needed to create a bright green future. "
