Facts About Solar Powered LED Lights

led street lamps

In spite of all the hype about combating global warming and switching to environmentally friendly sources, little attention has been given to the streetlights. Whilst they are crucial to the public, they are very energy consuming, and their servicing is costly. Thus, it is worthy of note when a big city like Los Angeles reports that it will replace 140,000 streetlights with LEDs.

LEDs are attaining traction as a great alternative to conventional lighting because they are relatively environmentally friendly, don’t consume much power and have long life spans. They survive so long, 14 years or more in some instances, that they can be regarded as “semi-permanent”.

Several of the most significant electronic firms see LEDs as the destiny of lighting. The LED market of seasonal lights, lights on the Empire State Building, and so on, is estimated to have a worth of $1 billion by 2013.

LED Savings Estimator for Common Commercial Lighting Fixtures


energy savings calculator

With the recent increase in electricity rates, it has never been more important for electrical contractors to show your customers some LED options.  Everyone knows that LED lighting fixtures are more energy efficient, last longer, and require less maintenance and replacement.  However, there will still be commercial customers and business owners who are nervous about the upfront costs associated with a full retrofit or new installation.

While some money will be spent upfront purchasing new LED fixtures, the savings associated with the reduced wattage fixtures can rapidly offset the initial costs.  And with rebates available for commercial customers of NGRID, NSTAR, WMECO, Unitil and Cape Light Compact, your customers will see a return on investment in a short period time with energy savings for years to come.

The Energy group at Granite City Electric is available to work with you on any new construction or retrofit project to ensure all…

“Hidden inside nearly every modern electronic is a technology — called power electronics — that is quietly making our world run. Yet, as things like our phones, appliances and cars advance, current power electronics will no longer be able to meet our needs, making it essential that we invest in the future of this technology.

Today [January 15, 2014], President Obama will announce that North Carolina State University will lead the Energy Department’s new manufacturing innovation institute for the next generation of power electronics. The institute will work to drive down the costs of and build America’s manufacturing leadership in wide bandgap (WBG) semiconductor-based power electronics — leading to more affordable products for businesses and consumers, billions of dollars in energy savings and high-quality U.S. manufacturing jobs.

Integral to consumer electronics and many clean energy technologies, power electronics can be found in everything from electric vehicles and industrial motors, to laptop power adaptors and inverters that connect solar panels and wind turbines to the electric grid. For nearly 50 years, silicon chips have been the basis of power electronics. However, as clean energy technologies and the electronics industry has advanced, silicon chips are reaching their limits in power conversion — resulting in wasted heat and higher energy consumption.

Power electronics that use WBG semiconductors have the potential to change all this. WBG semiconductors operate at high temperatures, frequencies and voltages — all helping to eliminate up to 90 percent of the power losses in electricity conversion compared to current technology. This in turn means that power electronics can be smaller because they need fewer semiconductor chips, and the technologies that rely on power electronics — like electric vehicle chargers, consumer appliances and LEDs — will perform better, be more efficient and cost less.

One of three new institutes in the President’s National Network of Manufacturing Innovation, the Energy Department’s institute will develop the infrastructure needed to make WBG semiconductor-based power electronics cost competitive with silicon chips in the next five years. Working with more than 25 partners across industry, academia, and state and federal organizations, the institute will provide shared research and development, manufacturing equipment, and product testing to create new semiconductor technology that is up to 10 times more powerful that current chips on the market. Through higher education programs and internships, the institute will ensure that the U.S. has the workforce necessary to be the leader in the next generation of power electronics manufacturing.

New York to Retrofit 250,000 Streetlights With Energy-Saving LED Bulbs

See on Scoop.itGreen Energy Technologies & Development

The phaseout is part of a long-term plan to reduce greenhouse gas emissions by 30 percent by 2017 and, Mayor Michael R. Bloomberg said, would save taxpayers money.

Duane Tilden‘s insight:

>The news conference was on Eastern Parkway in Brooklyn, where lights have already been replaced, expecting to save more than $70,000 and nearly 248,000 kilowatt-hours a year in energy. Unlike standard lights, which last six years, LED bulbs can burn for 20 years before they need to be replaced, the administration said, and the project is expected to save $14 million a year in energy and maintenance costs. […]

“People tend to like them,” she said. “It’s clear. It’s bright. It really does a good job in providing fresher light.” The project is estimated to cost $76.5 million.

The project is the first to receive financing through the Accelerated Conservation and Efficiency initiative or “ACE,” the administration said, a $100 million competitive program that the Department of Citywide Administrative Services created to expedite such sustainability projects.<

Congress and Light Bulb Regulation | The Energy Collective

Light bulbs, as you may recall, have become a perennial excuse for certain federal legislators to whip up the conservative base, by railing again new federal energy efficiency standards.

Duane Tilden‘s insight:

Relamping projects have been an easy way to score energy efficiency gains in buildings since the 1990’s.  Inefficient incandescent light bulbs have given way to fluorescent tubes, compact fluorescent and now LED technology.

Within these stages of development each form of lighting have seen their own evolution.  The driving forces for these increases in lighting efficiency are economic starting back with the 1970’s energy crunch.

Taken from a blog on CFL development & history:

“In 1973-74 the oil crisis took place and lamp companies needed to reduce wattage in their linear (tube) lamps to compensate. Many people had four bulb fixtures and were removing two bulbs, to save energy, therefore dropping sales by half. This forced lamp companies to create energy efficient solution.

Ed worked on creating lamp with reduced wattage by adding krypton and a conductive tin coating inside. This helped lower the wattage from 40 to 35 watts but he wanted to get down to 30 watts. He continued to work and finally the wattage went from 35 to 34 and eventually 32 watts!”
