LED Street Lights Cut Energy Use 85% in 12 Large Cities; LED $10M CASH for CLUNKERS Program Launched… (Energy Efficiency News Roundup)

June 20th, 2012 by  

Some energy efficiency news from around (other than our energy efficiency stories from the last week):

An LED street lighting trial in 12 of the world’s largest cities has shown energy savings of up to 85%.

The findings of LightSavers, an independent two-and-a-half-year global pilot of LED lamps in 15 trials across 12 cities including New York, London and Kolkata, are presented for the first time in a new report entitled, Lighting the Clean Revolution: The Rise of LED Street Lighting and What it Means for Cities.

Key findings include:

  • Surveys in Kolkata, London, Sydney and Toronto indicated that between 68% to 90% of respondents endorsed LEDs city-wide rollout. Benefits highlighted included improved safety and visibility.
  • LED lighting trialed lifespan ranges from 50,000 to 100,000 hours indicating a high return on investment.
  • LED failure rate over 6,000 hours is around 1%.
  • The Climate Group and Philips are calling for an international low carbon lighting standard to be created and implemented ensuring that citizens worldwide have access to energy efficient outdoor lighting.

Independence LED Lighting has launched a “comprehensive” $10 million CASH for CLUNKERS program for lighting. “The incentive covers the cost of banned T12 tubes, proper disposal of the toxic tubes and ballasts, and an LED Lighting Retrofit Return on Investment (ROI) Assessment. The incentive is for U.S. businesses that choose to retrofit with Independence LED Tubes, which are three times more energy efficient and last three times longer than the obsolete T12s.  To further assist qualified business owners, Independence LED provides $0 down financing programs providing net savings from the flip of the switch. The program runs through 12/31/2012.”

FPL has released summer savings tips that could help you save $250/year “with simple ‘do-it-yourself’ home energy fixes.” “When it comes to energy efficiency, a little goes a long way and there are several no-cost or low-cost measures we suggest that can add up to big savings,” said FPL energy efficiency blogger Danielle Mousseau.

LEDs are now available to residential customers in Puget Sound region. Puget Sound Energy has announced “the wide availability of light emitting diode (LED) bulbs and fixtures for the utility’s residential electric customers at participating retail stores. As the country phases out incandescent bulb technology in favor of more efficient and longer lasting options, LED technology has been viewed as a long term solution – though a costly solution.”

Technology innovation and continual cost decreases are fueling the spread of net-zero-energy buildings, Pike Research finds in one of its latest reports. “Several forces, including concerns about corporate image and branding in an increasingly sustainability-focused marketplace and growing interest in staying on the cutting edge of technology, are driving many in the construction industry toward the goal of producing zero energy buildings, i.e., buildings that produce as much energy as they consume through on-site and renewable energy systems.  Many of the technologies needed to deliver zero energy buildings, such as energy efficient HVAC systems, have already been developed.  Others, however, such as triple glazed windows and solar panels, are not considered cost-effective in comparison with conventional alternatives.  According to a recent report from Pike Research, over the next few decades, cost decreases in these existing technologies and innovation in emerging technologies, driven by stringent government regulations, will help make zero energy building more attainable.”

Vigilent swept the Higher Education Energy Efficiency and Sustainability Best Practice Awards in the HVAC Retrofit/Design category this year. “The Vigilent system, through advanced software and wireless sensor control technology, uses artificial intelligence to dynamically adjust cooling to optimally match real-time demand in the most efficient way possible.”
