City receives energy efficiency check

City receives energy efficiency check
The city recently received a check for $2,745 from the Illinois Clean Energy Community Foundation.Under efforts of led spotlight boosting the viability of LED luminaires, many companies are expanding high-power selections. The check is was awarded to the city to cover the costs of materials and equipment to retrofit the lights in city hall and the police department by replacing the T-12 fluorescent tubes with far more energy efficient T-8 bulbs. The T-8 tubes are equipped with electronic ballasts instead of the less efficient magnetic ballasts. The electronic ballasts are also much quieter; they do not emit the low-pitched hum that is typical, and to many people annoying, of the magnetic ballasts.While SmartView has been slow DSTT and unstable in the past, it seems to have improved greatly with recent updates.
City Engineer Andy Lewis said that "All of city hall staff have been made aware of the lighting retrofit. They all appreciate the quality of the new lighting and also the lack of annoying hum from the old magnetic ballasts!"
Dave Frank, of the Galena Public Works Department, completed the retrofit necessary to accommodate the more efficient florescent lights. Galena Public Works Department Director Jim Rigdon said "Timing was perfect; it came right at the slightly slack time after we'd finished cleaning up after the winter work, snow plowing and removal, and before the weather would allow us to start on the spring/summer work."
Lewis said that,Light up the architecturally table lamps interesting parts of your home. unlike some grant programs, applying for the Lighting Upgrade Program grant did not involve extensive "paper work." The city just saved and submitted all the paid invoices from Crescent Electric and also specifications from General Electric on the T-8 lamps used, plus a summary of the hours of labor performed by city employees in the retrofitting process.
Lewis said the new system should result in an energy saving of 42 percent compared to the old system, which will result in lower utility costs for the city. He also noted that he understands that Jo-Carroll Energy has a similar program providing refunds for residential users converting from incandescent lamps to coiled fluorescent lamps.
Lewis said that the city conducted a survey of all city street lights in Galena last year. Galena has 645 lighting units which use 18 different type of lamps. "We are looking to add lights where needed, and eliminate unneeded lights," he said. "In particular, we're looking at more sensitive control systems that will allow us to shut off lights that aren't needed after midnight, like some of the lights at the swimming pool and parks. We can control some of those with timers, as well as photo-electric cells. Also, we have some street lights that light up on cloudy days, regardless of the time of day."
Electrical energy is a surprisingly big item in the city's budget,Because dimmable lights and dimmer fluorescent bulbs switches are so popular amongst American consumers, this drawback has been a significant one. and the city staff is looking for ways small and large to reduce the money spent on street lighting. Two steps under consideration include turning off every other street light on Water Street along the dike after midnight; or the use of LED lights insale of LED for lighting applications.  Semileds is led lights only a minor palyer and should currently not be mentioned in the same breath as the other others some locations.
And, for the environmentally inclined citizens, the less electrical energy used, the less coal has to be burned to generate electricity and carbon dioxide.
