Reduce Your Energy Bill in the Winter Months
Usually during peak months like winter, we will see a sharp rise in our electricity bills. Sometimes we wonder why could such an injustice be enacted by our power companies. Other times we get GCN Introduces upset because we knew we should have Upcoming Project taken some precautions before, but now (Page 3) it’s too late! Fear not. There are several Other Information manageable ways to not only decrease your upcoming bills but also to prevent (Page 4) that disconcerted afterthought when viewing February’s electricity bill. The first tip is easy - turn your Taylor Cook thermostat to a constant 68 degrees durTeam Manager ing the daytime. For every degree you lowEmily Corban er between the 60 - 70 range, you can save Treasurer approximately five percent on your next Jennie Fan bill. Maybe saving only five percent on Public Relations Trenton Winford your energy bill isn’t enough for you, and you want to really boost your energy savSecretary ings. Next, when leaving the house for an extended period of time, or even at nighttime, you can turn your thermostat down Local Schools Partner with TVA (Page 2)
to about 55 degrees. This can save up to 20 percent on your energy bill for the month! Keep in mind that you should avoid setting your thermostat below 50 degrees to prevent freezing pipes. Second, regularly replace dirty filters. Air and furnace filters should be replaced to ensure maximum efficiency during the winter times. When used properly, this step can ensure up to another five percent decrease in your energy bill. Third, lower your water heater temperature. Sometimes our water heaters are set too high without us even realizing it. This can cause problems especially in the winter because of the amount of energy it takes to keep the cold water heated at a higher temperature. Usually, the ‘normal’ range for the water temperature to be contained at is approximately 120 degrees. Cont. on Page 3 (Winter)
What’s in a Name...of a Lightbulb
It can become an overwhelming task for consumers to select and purchase new light bulbs with the variety of options available on the market today. The expansion in choices for light bulbs from simply Incandescent bulbs to a variety of Compact Fluorescent, Halogen, and LED light bulbs on the market today has given consumers more choice but more confusion when purchasing light bulbs. Previously consumers only had to compare wattage and pricing when selecting a bulb. Today’s light bulb labeling reveal not only a light bulb’s wattage but also its lumens, kelvins, estimated yearly energy cost, life span, and costs to consider. With all these added options to compare when purchasing light bulbs it is important to understand what all these options mean.
This is where CFL and LED bulbs gain their energy saving advantage over incandescent bulbs which release most of their energy as heat and are highly inefficient.

Lumens- Lumens describe a lightbulb’s brightness or intensity. Consumers can determine how to get the same brightness of a 100 watt incandescent bulb with a much lower wattage CFL.

Local Area Public Schools Team up with TVA
Local area public schools have spent the last two years trying to save money for the school district by cutting energy costs through a project funded by the Tennessee Valley Authority. Similar to Green Campus Network on the Ole Miss campus, the TVA Green School Initiative program is a public school program in both Oxford and Lafayette County schools. The setup of the Green School Initiative is rather simple: a team of adults on administration/staff aid a team of
students in planning and coordinating energy efficient projects. These students have the ability to actively participate in crafting policies that affect the school’s energy consumption. They have the opportunity that many other students do not receive. “The TVA has been excited about it, and in the first year, there were 21 schools in the whole program, and by the second year there were 80,” Alisa Fye, a TVA participant, said. The Oxford Eagle reported on 29 November 2011 that the Ox-
ford School District, through the work of the Green School Initiative, saved over $23,000 for that fiscal year. That amount is equal to a 7 percent reduction in energy costs for the year. TVA is looking to expand the program to other school districts in the TVA area, and they plan to use the success of Oxford’s local schools as a model. - Trenton Winford -
GCN Team Prepares for Big Winter Project Surprising Fact: a common portable space heater can consume up to 1500 Watts. Both conventional ovens and hot tubs also consume around 1500 W. That is a lot of energy, especially considering there are other ways to keep warm. Working in an office ourselves, we understand that some days it seems colder in the office than it is outside (“Why is the AC on in January?!”) and that in most buildings occupants cannot control the thermostats. But if we could just keep a jacket or small blanket around the office for those days, we could save so much energy! And that is not the only way we can save energy. The GCN team developed a Pledge asking everyone to commit to 1) “remove space heaters from (their) office space and replace them with an alternative (i.e- jacket, Snuggie, etc)” and 2) “turn off electronics and lighting when leaving the office and use energy-sav-
ing modes while electronics are in use”. We invite everyone to sign the pledge and join our efforts trying to save energy this winter! To sweeten the deal, every person who signs the pledge will entered into a drawing for one of our Winter Warmers Baskets, stocked with goodies to keep you warm through the coming cold. Now I know what you’re saying, where does the Snuggie part come in? We get it. You don’t want to look like an abominable snow secretary sitting at your desk. So our team got to thinking, how can we stay warm and cozy when we’re on campus, without using space heaters which use so much energy? What could be more warm and cozy than a Snuggie? Both functional and fashionable, these customized Ole Miss Snuggies are perfect to keep in the office for days when it seems colder in the office than it is outside. How can
you get one of these you might ask? When you sign our online pledge you have an option to turn in your space heaters. Those who check “Yes, I want to donate my Space Heater” will have their name entered into a drawing for 1 of 20 Ole Miss Snuggies. Cont. on Page 4
Winter If you have a water heater that only has settings for low, normal, and high, then normal should be about 120 degrees. Setting it to this temperature has the ability to save you another ten percent on your energy bill. Fourth, seal all leaks. Sometimes there are cracks and crevices in doors, windows, pipes and vents. It is beneficial to find ways to caulk these areas to maximize efficiency. This way, less cold air will be circulated through your house, which would cause the heater to run more efficiently since it does not have to maintain the house at a higher temperature to make up for leaks.
Lastly, think of investing in some Energy Star® appliances. If you’re in the market for some remodeling, choosing Energy Star® would be the direction you should head if looking to save some extra bucks on your energy bill. Energy Star® appliances have the ability to save up to 30 percent in energy costs. If you can implement these suggestions into your homes, I can guarantee you will see a significant difference in your energy bill for the next month. Can you just imagine the added energy savings? You could buy yourself a treat with all that saved money! - Jennie Fan -

Bulbs In fact, according to the EPA, the use of CFL bulbs actually lowers the amount of mercury in the environment overall by reducing the amount of energy from electrical power plants, which are the largest emitter's of mercury. Understanding all the options available, it is easier to make decisions when purchasing light bulbs. With all the advances in CFL bulbs, it is also easier to find the right bulb to suit your lighting preferences while also saving energy and money.
