energy saving

The U.S. Department of Energy (DOE) has released analysis findings for markets where light-emitting diodes (LEDs) compete with traditional lighting sources (e.g., incandescent and fluorescent). The January 2011 report provides estimates of current energy savings, plus potential savings if these markets switched to LEDs overnight.

DOE analyzed the following markets:

  1. Four general-illumination applications
    1. PAR, BR, and R replacement lamps;
    2. MR16 replacement lamps;
    3. 2-foot by 2-foot troffer fixtures; and
    4. general service A-type replacement lamps
    5. Four outdoor applications
      1. roadway,
      2. parking,
      3. area and flood, and
      4. residential
      5. Four applications for consumer electronic displays
        1. televisions,
        2. laptops,
        3. monitors, and
        4. mobile handsets.

LEDs in these markets saved approximately 3.9 terawatt-hours in 2010, equivalent to the electricity needed to power more than a quarter-million average U.S. households.

If these markets switched to LEDs overnight, the energy savings would be the equivalent of taking 21 million residential households off the grid based on 2010 performance level.

If LED replacements within each market improve according to DOE’s predictions for 2020, the energy savings would be equivalent to taking nearly 32 million households off the grid.

California passes a new law that takes effect January 1, 2011 requiring improved energy efficiency in all light bulbs in the State.

California consumers also will save money buying LED lighting. has the best in energy efficient LED lights and now there is much more reason than ever before to change your lighting to LEDs.

A new federal law will start saving consumers money by improving the energy efficiency standard for incandescent light bulbs sold in California on or after January 1, 2011.

The standard – Energy Independence and Security Act of 2007 (EISA) – will save California consumers money with new bulbs that offer the same amount of light while using less power. Passed by Congress and signed by President George W. Bush, EISA created new energy efficiency standards for light bulbs. The law is designed to reduce energy use and associated pollution and make the United States less dependent on foreign sources of energy. While the country will adopt this standard on January 1, 2012, California was given authority to implement the national standards one year earlier to avoid the sale of 10.5 million inefficient 100-watt bulbs in 2011 which would cost consumers $35.6 million in higher electricity bills*.

Reducing energy use in California also results in improved environmental quality by avoiding the construction of new power plants and air pollution from burning fossil fuels.

The standard in California states that a 100-watt bulb manufactured on or after January 1, 2011 must use 28 percent less energy (i.e. a 100-watt bulb may not use more than 72 watts). The new 72-watt replacement bulb will provide the same amount of light (i.e. lumens), use less power, and cost less to operate.

New lighting technology has become more efficient than old-fashioned incandescent bulbs. Approximately 90% of the electricity used by traditional incandescent bulbs is wasted as heat instead of visible light. Replacing traditional incandescent light bulbs with more efficient halogen, compact fluorescent bulbs (CFL) or light-emitting diode (LED) bulbs will save consumers money while still offering same amount of light.

The new standard is technology neutral and allows consumers to choose among a variety of high-performance products for their replacement lighting. Additionally, it does not affect the existing supply of incandescent light bulbs stocked in retail stores or incandescent light bulbs already in use.

This standard builds on the California Energy Commission’s long and successful reputation of saving consumers money though energy efficiency standards. Since 1978, California’s appliance and building efficiency standards have saved more than $56 billion in electricity and natural gas costs.

Palo Alto, California is giving its residents a holiday gift. They are offering each resident the chance to trade in their incandescent lights for new LED holiday lights for their decorations.  LED lights consume 10-50 times less energy than old holiday lights.  LED lights are also cool to the touch, lowering fire hazards.

KCBS’ Betsy Gebhart reports

The program will run through mid-January.  Let’s hope more cities adopt this environmentally-admirable attitude in the future.

Did you know…

A 60 watt LED light-emitting diode light lasts over 30,000 hours and higher wattage LED lights often last over 100,000 hours.

LED lights burn a small fraction of the energy a regular or CFL light bulb uses to produce the same amount of light.

LED lights aren’t hot to the touch. Incandescent and CFL bulbs retain more heat due to the fact they aren’t transferring energy as efficiently and waste a lot of your electric bill making heat.

Old light bulbs pollute with dangerous mercury which can get into landfills and water supplies, and can harm you directly if the bulb breaks in front of you.

LED lights are a clean pure energy light source.

(the picture on the right – courtesy of – is of a beautiful color-changing LED Strip light) is supplying LED lighting to a growing number of hospitals and the cost savings are magnified by the fact that hospitals use their lighting 24/7/365.  Hospitals use 2.5 times the amount of energy as a similar-sized commercial building. Because hospitals never close, and because of the way hospitals operate, they are heavy energy users and it turns out that 50% of their electricity costs are spent on lighting because in hospitals’ lights are always on.

Hospitals and health care facilities account for a disproportionate amount of energy use.  The Economist reported that a study published in the Journal of the American Medical Association estimates that America’s health-care industry accounts for 8% of the country’s greenhouse gas emissions. In Germany, a study by the Viamedica Foundation showed that a hospital’s energy expenditure per bed was roughly the same as that of three newly built homes.”

Switching to LEDs can save hospitals upwards of 80% off their electric bill.  Since hospitals account for one-third of total health care spending nationally, saving money on the energy cost of hospitals as a group will make a substantial dent in health care costs.

The Economist article also reported that many hospitals are switching from standard light-bulbs to compact fluorescent or LED lights. The Dell Children’s Medical Center in Austin, Texas, was the first hospital to be certified “platinum” under the Leadership in Energy and Environmental Design (LEED) standards of the United States’ Green Building Council—the highest designation there is.

LED Saving Solutions is offering $100 Million in high-tech LED lighting retrofits to over 100 hospitals and major hospital groups across the United States..

According to the American Hospitals Association, there are over 5,000 registered hospitals in the USA.  Public sector hospitals are about 1/4 of that number.  If on average, each hospital saves $40,000 a month or $500,000 a year, and if the cost of putting in the LEDs is covered by the savings share initiative of the federal government, the collective savings are, then the savings per hospital are over $1million per year .  If half of the hospitals switch to LEDs and participate in the lighting retrofit, then the annual savings is half a billion dollars.

Wouldn’t health care reform be helped tremendously if every hospital switches from energy-foolish incandescent lights to energy-saving LEDs?

Rubio’s, the San Diego healthy fast food chain that popularized fish tacos, is introducing a new restaurant design in its fifth outlet in San Francisco that includes eco-friendly features such as counter tops and panels made from a recycled material called marmoleum, an open kitchen, and LED lighting that uses less energy.    

Cree, Inc. (Nasdaq: CREE), a market leader in LED lighting, announces that LR24 recessed LED luminaires have been installed in the National Air and Space Museum. Designed for the new “Moving Beyond Earth” exhibit, the Cree LED lights replace high intensity discharge work lights, offering the high lumen output and efficacy required to work in the gallery.
