The phantom menace and being green.

December 11th, 2009

How do phantom charges affect your electricity bill?  Is it worth worrying about?  Phantom charges occur when appliances use electricity when you are not using them.  Just going around the room that I am sitting in while writing this paper I can list several things that are using electricity and are not being directly used. 

The volume on the computer; has a light on right now, as well as the camera charger.  The iPod charger is lit up showing the time but we really don’t need a second clock in the same room and the hard drive is lit up and we don’t use this daily.  In the living room our surround sound has a power light and also the DVD player.  When we turn off the TV the DVR is still on.  In the kitchen I can say that the oven shows the time all night but the inconvenience of turning that off isn’t worth it.  There are several cell phone chargers plugged in right not charging phones.  As you can see we use a lot of electricity that we don’t need to. 

You can reduce your electricity bills by 10% simply by unplugging appliances or switching devices off at the power point they are connected to when not in use.   Even though you hit the power switch on your gadgets they still consume electricity.  The amount of usage of these appliances can be anything from .5 to 5 watts per hour; which may not seem like a lot but when you multiply by the number of hours a day and the number of households in the world this adds to a lot of carbon pollution.  Even though this week’s task is about “turning off lights” I would like Ben to focus on how much we are consuming in phantom charges.  If you have any tips on how to conserve, please write in the comments below.

Why should I turn off the lights?

December 10th, 2009

I have been trying to follow the rules of this week’s green challenge by turning off all lights when I leave a room and I understand that it saves energy, but I think it would be a good exercise to find out specifically why this is a good idea.  “Save energy” is such a broad term and it seems to help me to take a look at specific reasons why I should be turning off lights to save energy.

One of the most common ways electricity is created is by burning fossil fuels.  When fossil fuels, such as coal, oil or natural gas, carbon dioxide is released into the air and that is the nasty stuff that leads to global warming.  So, by keeping the lights on when you are not using them is just an exercise in wastefulness.  To turn OFF those same lights is an expression of conservation and only using what you need.

How big of a difference does this make?  Although I usually really like doing the math, I am going to rely on other people’s math today.  A 60 Watt light bulb consumes .06 Kilowatt hours of electricity.  If I can prevent this light bulb from being on 3 additional hours by turning off the light when I am not using it, this adds up to .18 kWh, or about 66kWh per year.  According to this site, 1 kWh of electricity generated from coal creates 1-3 pounds of CO2.  A simple step such as turning off a light saves 66-198 pounds of CO2 per year.  If you start talking about households where lights are left on all the time, I suppose the potential waste can get into the thousands of pounds.

This is such a small step and such a big reward for our planet.  Let me know if you have any other interesting information on the subject in the comment area below.
