Brighter Cities One Bulb at a Time

 

If you study the energy industry, you’d find that we are in the middle of a revolution right now. Everyone from manufacturers improving appliances to consumers renovating their homes, energy efficiency is taking the country by storm.

 

In a recent article in Energy Manager Today, Danielle Stewart examines how America is making brighter, more efficient cities slowly, but surely. Take for instance how twenty years ago, “every building in America was lit up with inefficient light fixtures. Now, consumers and cities can choose from a wide selection of compact & linear fluorescent and LED bulbs that slash energy consumption without sacrificing light quality or brightness.”

 

The author goes on to discuss how cities are increasing their efficiency projects and buildings. “Consumers, municipalities, and corporations alike are realizing that energy efficient upgrades can protect the environment while actually saving money.”

LED Street Lighting in Buffalo, NY

LED street lighting

The city of Buffalo recently updated their street lighting to LED, increasing security, safety, and savings for the city.

The streets of Buffalo, New York are a little brighter these days. The city recently updated their street lighting to LED, increasing security, safety, and savings for the city.

During 2011, commercial and institutional buildings, and street and highway lighting, consumed “about 275 billion kilowatt hours for lighting or 21 percent of commercial electricity consumed,” according to the U.S. Energy Information Administration.

Cities are finding out quickly that changing out older streetlights for LED lamps can reduce energy use. Compared to high pressure sodium lamps, LEDs use less energy, and also handle outdoor temperature changes and moisture better. Plus they are more attractive for use as outside security lights, and provide better directional lighting.

“LED streetlights can quickly show a return on investment by offsetting the high up-front expense with lower energy costs, longer life, and reduced maintenance.”

LED Street Lighting to Surpass $2 Billion by 2020

The market for LED street lighting is expected to generate more than $2 billion in annual revenue.

Falling costs and improvements in efficiency are driving the increased sales of LED street lighting lamps. According to a new report from Pike Research, “LEDs will become the second-leading type of lamp for streets in terms of sales by 2020.”

The costs of LED street lighting have fallen as much as 50 percent over the past two years, and are expected to continue falling. The market for LED lamps is expected to generate more than $2 billion in annual revenue. The current most popular street lighting is high pressure sodium lamps.

“Smart street lighting systems can provide a backbone for other smart city applications, and conversely, a city investing in networking capabilities for smart city applications should also be looking to include better management of street lighting,” says research analyst Jesse Foote.

The Smart Street Lighting report also noted how the adoption of LED street lights is seriously hindered by the ownership models and tariff structures in place across the U.S.

“If utility companies own street lighting systems and charge a fixed tariff per light to municipalities, then towns have little financial incentive to pay for upgrading their lights. However, the potential for significant energy savings, reduced emissions and improved quality of service, combined with falling LED prices, means that more and more cities will find this an attractive proposition over time.”

The report analyzed the global market opportunity for lamp upgrades and lighting controls in five public outdoor light categories: highways, roads, parking lots, city parks, and sports stadiums.

Golden Gate Bridge May Get LED Makeover

The famous Golden Gate Bridge may get an LED makeover. As part of its Gateway program, the Department of Energy has evaluated the use of LED retrofit kits to replace the existing lights on the San Francisco landmark.

“The goal of the study was to identify solutions to reduce maintenance and energy use without compromising the quantity or quality of existing illumination.”

Currently, four types of luminaries containing HPS or LPS lamps are currently used. Various replacement options were evaluated, including custom LED retrofit kits, fully-integrated LED or ceramic-metal halides.

Researchers found that commercially-available LED retrofits could not be found that would be suitable for installation within the existing luminaire housings. However, custom LED retrofit kits would help save energy while maintaining light levels.

Cities Are Satisfied with LED Streetlights

A recent survey found that 95 percent of cities that have implemented LED streetlight projects were satisfied with the performance of the lights.

A recent survey found that 95 percent of cities and municipalities in the United States that have implemented LED streetlight projects were satisfied with the overall performance of the streetlights.

Northeast Group, a Washington D.C.-based research firm, surveyed nearly 100 cities and municipalities across the U.S. that have implemented some form of LED streetlight initiatives.

“LED streetlights are transforming cities and municipalities across the U.S.,” said the firm. “LED streetlights [are] helping save money through reducing energy and maintenance costs.”

Surprisingly, most of the cities surveyed had only converted a small percentage of their streetlights to LED. In addition, LED streetlights also turn on and off nearly instantly and have dimming capabilities. The controlled features on the streetlights help further reduce energy consumption.

Filling Up with Natural Gas

With natural gas booming, more municipalities and cities are looking to install natural gas filling stations.

“The concept of adding liquefied natural gas stations is built on the shale gas boom,” said Jack Christensen, the director of facilities and energy management for the turnpike commission.

“It’s a high-quality fuel; it helps with pollution, it helps with national security on some levels, and we wanted to see if it would be a good fit for the turnpike.”

The use of alternative fuels can be essential to the future of clean transportation.
