NYC Adapts Sustainable LEDs in a Big Way

NYC will replace all of the cities street lights with energy efficient lighting.  Michael Bloomberg, Mayor, “ … announced that all 250,000 of New York City’s street lights will be replaced with energy efficient, light-emitting diodes (LEDs) by 2017.”

In general benefits include reduced energy (LEDs are more energy efficient than current city lighting) and lower maintenance costs (LEDs last many times longer than other lighting types).

Specific benefits:  “… reduce greenhouse gas emissions from city government operations 30% by 2017 … [and recutions of] … around US$6 million in energy and US$8 million in maintenance costs a year, …”

Ikea Will Sell ONLY LED Lighting by 2012

Ikea will likely be the first retailer to only sell LED lighting by 2016 to “ … enable millions … to live a more sustainable life at home and save money on their energy bills.”

Ikea is also converting all their in-store lighting LED lighting – over 1 million lights.

Why LED:  LED  is more energy efficient (uses approx. 85% less electricity) and longer lasting (up to 20X).

The one negative to LEDs is their higher initial price (but lower total cost of ownership).  To help make LEDs more attractive to consumers Ikea “ … will make sure our LED prices are the lowest on the market …”

Promoting LED lighting follows other green / sustainable practices including no longer selling incandescent bulbs (2010) and nor using plastic bags (2007).

EvoLucia Aimed LED Ligthing

EvoLucia Lighting logo


 EvoLucia Aimed LED Lighting is not only more energy-efficient and environmentally friendly than other light sources, it is also much more effective. Through our patented Aimed Optics™ technology, we have demonstrated that less overall light is needed if the light is correctly focused on the target area, which allows for more efficient lighting solutions. We have identified an immediate opportunity, particularly in the outdoor lighting market, to supply high quality energy-efficient lighting solutions through this patented technology. We continue to develop and refine our products to serve the market and are actively pursuing alliances that will allow us to drive down the cost of producing our “Aimed LED Lighting” products.

Simply put, “aimed LED lighting” is the method of providing exactly the light that’s needed, where it’s needed. Through our patent-pending Aimed Optics™ technology, EvoLucia optimizes utilization of LEDs to put the most foot-candles on the ground, in the pattern required, with the best uniformity, using the fewest LEDs and the least power consumed.

While traditional luminaires are utilize one single, omni-directional light source per fixture, such as a metal-halide light bulb, EvoLucia’s Aimed Optics™ lighting technology platform uses multiple LEDs. A reflector directs the light in the desired pattern and provides the requisite number of foot-candles exactly where they’re needed.

It is both cost advantageous and energy-efficient to minimize the number of LEDs used to achieve the required number and uniformity of foot-candles in the pattern desired. In order to do this, each LED (or small group of LEDs) must be aimed and focused optimally. The method for doing this is the basis for the Aimed Optics platform.

Incandescent Bulb's Days (May Be) Numbered ...

Incandescent light bulb - its days may be numberedThe Energy and Security Act of 2007 was signed into Law on Dec 19th, 2007.  Along with items like requiring higher CAFE for cars there is an interesting note about ... the incandescent light bulb.

Though most people are saying that the incandescent bulb will not be sold after 2012 - it is more correct to say that the current energy inefficient incandescent bulb as sold today will not be available.

It is likely that the initial make up supply of bulbs will be from either higher efficiency incandescent bulbs or as in intermediate step - CFB. 

One little problem about CFB is that they contain MERCURY which is a rather nasty environmental pollutant - one linked to health effects in younger children.  Maybe lower cost LED bulbs will be available by 2012?

So far now ... maybe it is time to stock up on the old incandescent bulbs ... 2012 will be here before you know it.

Here are some green ideas for a green Christmas:

(1) Buy a live (balled) tree instead of cutting down a livbe tree and throwing it in a landfill.
>> Get some credit back if you (like me) mulch the tree instead of throwing it in the trash).
>> Get some credit back if the tree was grown w/o extra chemicals and such.

(2) Get some new LED lights.  they are brighter and use way less electricity and should LAST A LONG time.  When your old strands are no longer working - Go with LEDS.
>> Added Bonus - no toxic mercury in LEDs!

(3)  Use paper shopping bags to wrap your presents and then recycle them instead of throwing them out with the trash.

(4) Recycle what you can of gift packaging (cardboard and paper are an easy one ... #6 PS if you ahve a place to take it.
>> Get some extra credit for buying gifts with minimla or green type packaging.

(5) Whatever type of tree you choose - consider recycled ornaments.

LED Lighting Generates ROI for Ann Arbor MIchigan By Halving Energy Use

Ann Arbor Michigan works with Cree to install LED solid-state lighting in the city's streetlights generating a payback from energy savings, while reducing greenhouse emissions. ... LED Street Lighting
... "Ann Arbor expects to install more than 1,000 LED streetlights beginning next month. The City anticipates a 3.8-year payback on its initial investment. The LED lights typically burn five times longer than the bulbs they replace and require less than half the energy. Each fixture draws 56 watts and is projected to last 10 years, replacing fixtures with bulbs that use more than 120 watts and last only two years. Full implementation of LEDs is projected to cut Ann Arbor’s public lighting energy use in half and reduce greenhouse gas emissions by 2,425 tons of CO2 annually, the equivalent of taking 400 cars off the road for a year. Detroit Edison, Ann Arbor’s local utility provider, will meter the new LED streetlights with the intent to gather sufficient information to develop new LED-based tariffs. " ...

Mark Pryor of Arkansas."

"Incandescent bulbs currently consume 42 percent of the electricity generated in the United States, but only provide 12 percent of the country’s artificial light, said Bryan Dundan, a Philips Lighting vice president. ...Instead of incandescent lights, coalition members advocate implementing technologies already available today, such as compact fluorescent lights, halogen lights, and light emitting diodes (LEDs), which require less electricity to produce the same amount of light as an incandescent bulb.
