I didn't know where to put this so here it is.
I was looking at my patio last night and I have two flourescent fixtures holding two 40-watt tubes each. On any given night both lights are on for a duration of maybe five hours. Each fixture burns 80-watts per hour so two fixtures burn 160-watts per hour. Wow no wonder my electric bill from HELCO runs almost $450 a month so I turned off one of the two fixtures and immediately saved 50% off of that particular lighting situation.
Then I read today's SB letter to the editor about how Hawaii's DOE schools are trying to reduce their electrical demands and welcome the use of photovoltaic panels to reduce their electrical costs.
Have you ever been in a classroom? How many flourescent lights are on for roughly 9-10 hours a day? Those long 8-foot tubes must consume at least what 80-watts each! And there's at least four per fixture and I'd imagine at least 10 fixtures per room. That's 2400 watts per hour or almost half a megawatt per day per classroom! And that's only lighting! Couple that with a computer room with ten computers running 400-watt power supplies. In an 8-hour day that can amount to 32,000 watts.
Ways to reduce their electrical demands? How about using the more energy efficient CFC flourescent bulbs. A 7-watt CFC bulb puts out the equivalent of a 60-watt incandescent bulb. How about using laptops instead of power hungry desktops. A typical laptop power supply uses around 90-watts of electricity per hour as opposed to a typical desktop computer with a 400-watt power supply. Never mind the monitor.
Kamehameha on the Big Island uses laptops then stores them away in vaults so if there is a break in the computers are safe.
Speaking of conserving power, I wonder if the state of Hawaii when tabulating the cost of replacing those thousands of feet of copper wire from freeway lighting is also figuring the amount they're saving because those lights aren't on so they can't be using electricity so they must be saving the state a bunch of kala for every night these lights remain off.
Once I mentioned to my friend as we flew over Honolulu one night that if the state and c&c of Honolulu were to shut down every other street light on Oahu, their energy bill on street lighting would be reduced by 50%. That's a hugh savings right there.
