As a follow up to my previous blog about Energy Efficency I came across a great article in the Report on Business written by Martin Mittelsteadt. It follows up to my previous blog on Energy Efficency and cutting our Energy Expenses and saving on the HST taxes. This is about lightbulbs, specifically for a Commercial application, but it can also be applied to our residences.
The incandescent light bulb goes back to the time when our Peterborough works GE plant was known as the Edison Electric and my great grandfather Charles Huffman was the foreman of the shop were they built electric street cars. The fluorescent bulb which has been used commercially for offices stores and plants is 1930's technology. As the incandescent bulb has been forced off the market as an energy hog, new technology is being developed to replace the old light bulb.
A Canadian company, CRS Electronics is betting it's future on the latest technology the energy efficent LED ( light emitting diodes ). They are marketing now to the commercial market, however, in time they will be marketed by the Philips and General Electic's of the world for home use. The cost benefits of the energy efficent bulbs is remarkable, especially for 24 hour a day use. CRS bulbs cut energy use by 88% and are expected to last 25 times longer, yet still having the brightness and look of standard lighting. They are energy efficent because 80% of the electricity they use is converted to light while an older incandescent bulb convert only 5% and thus produce incredable heat. Even the new compact fluorescent bulbs ( I just hate them ) are only converting 25% of the the electricity and are really not that energy efficent.
Like I said they are not inexpensive to purchase, about $ 60.00 a bulb, especially compared to halogen, but in large commercial or institutional buildings the savings are real. Humber college purchased 1000 bulbs from CRS and estimates that over the nine year life span the school will save about $ 500.00 per bulb. Also, it saves labour costs as the school would have used 3000 halogen bulbs and they also would have been sent to landfill.
The lighting market is similar to the computer chip market 10 years ago, so expect dramatic price reductions in halogen and LED. lighting and the energy efficency will transfere to our residences.
