Having the heater on all the time unnecessarily causes your carbon footprint to expand. I will discuss some instances when you do not need it. We tend to leave the heater on all night when we can easily find warmth and comfort snuggled inside a blanket. Another time you can turn it off is while the house is empty. Whenever you go to school and your parents go to work, that would be a good time to turn it off. When you are having a get together, gather around a fire instead of having the heater on. Get creative and think of other instances you can turn off your heater.

    I agree. Many people do leave the heater on at night when there are many other solutions such as a blanket. As well, I live in Texas, and heating is really not strongly needed at nighttime because it never gets that cold. Many other states similar to the climate in Texas should promote no heating at night.

Hello everyone, my name is Reece, and I live in the USA. I will be discussing having the heater on at night, wasting water, and using a vehicle unnecessarily. Instead of having the heater on at night, just cozy up under heavy blankets. It is eco-friendly and very comfortable. I will discuss turning the water off while you brush your teeth or even when you are shaving your legs. Also, instead of driving a car to a friend’s house who lives really close, ride a bike or walk there.

Hi, I’m Shelby and I’m from Florida. My carbon footprint was way below average barely even going over 4,000 as my total. I use a lot of recycled items, including clothing. I try driving my car as little as possible since its horrible for the environment and gas is expensive! We recycle in our house both plastic and cardboard/paper. Something I would like to see my family do is to eliminate the need for our cars. It would save us so much money and help the environment as well.

Hi, I’m Brittany and I’m from Florida. My carbon foot print was around average for my area. My home energy usage was the only thing that deviated from the normal amount because it was a little bit lower then normal. My family recycles tin and we always turn out lights out when we are not using them so I suppose that lowered the amount of our usage. One of the things that I would like to do is start recycling plastics in my home. We go through many plastic bottles and it could be useful for us to recycle them along with the tin cans that we already recycle.

I’ve always lived far away from every school that I have attended. All through elementary and middle school, it would take me over 45 minutes to get to school, depending on the traffic. It’s basically the same amount of time now that I am in high school. I didn’t realize how much carbon driving 45 minutes to and from school each day put out. Also, living in Texas, I travel to other cities that are about 3 hours away very often. I drive to San Marcos to visit my sister in college a couple times a year and then travel to places like Austin, Dallas, and San Antonio for short vacations throughout the year. In order to put out less carbon in the world, I am going to try to carpool with more people who live near me, instead of just the one I carpool with now.

    I live in Texas and was surprised as well by how much carbon is realized taking short, frequent trips to San Antonio and Galveston for sports and to visit family. I think it would be ideal for the buses I take for long sports travel to be more efficient because that would decrease the carbon emissions by a lot.
  • Elena D-USA Elena D-USA Oct. 9, 2013
    I agree with Ellen. Traveling in Texas uses a lot of carbon because everything is so far away. Traveling on buses for sports can be taxing on the environment because of all the carbon a bus releases. If schools would buy more fuel efficient buses then they carbon emissions would be greatly reduced.

Venessa A-USA, Oct. 6, 2013

Hi! I’m Venessa and I attend school in Houston, Texas. After getting the results of my carbon foot print I found that my home energy usage was way above average for my region. Here in Texas, the average carbon foot print for home is 9385 kg per year. My home carbon footprint is 11,763 kg per year. Realizing this really made me think about what my family could be doing at home to be using so much energy. When I really thought about it, I came to the conclusion that we leave many lights on when we leave a room, and the fact that we don’t have energy efficient light bulbs in our home makes this worse. Also, my siblings and I take pretty long showers. I never really thought twice about the amount of water we could be wasting. But, after learning about my carbon footprint I now am aware of the ways I can reduce it. I can take shorter shows and switch out my light bulbs.

    Thanks Brittany and Helena! I think I will try to get my family to use water-saving shower heads. I think it will really help decrease my carbon emissions. Doing little things like this can really help because I take long showers. Here is a good guide to help conserve water in other areas. http://fi.edu/guide/schutte/howmuch.html
    I think that putting water-saving supplies on things such as sink faucets and not only shower heads will help too.
  • Anastasia K USA Anastasia K USA Oct. 10, 2013
    I agree with you Vanessa. Another helpful way to decrease carbon emissions that come from your home is to either start a garden, compost, or both. This article explains the importance of composting and the effects it has. http://urbanext.illinois.edu/compost/process.cfm If you do start your own garden then you will be able to grow your own produce. This will also decrease the amount of CO2 emission caused by food transportation and processing.
  • Venessa A-USA Venessa A-USA Oct. 10, 2013
    I think being able to grow my own produce in a garden is a great idea, Anastasia! My mom just recently started growing vegetables and I think this will greatly reduce my family's carbon emissions for food transportation and processing.

Helena B-USA, Oct. 6, 2013

I am Helena and I live in Texas which is in the United States. After calculating my carbon footprint, I found out that my biggest carbon contributor was from my transportation. My carbon footprint for transportation each year is 10375 kg per year, compared to the average in my region, 6387 kg per year. This is because I travel to and from school every day which is 9 miles each way as well ad driving to other activities after school and on weekends. My family and I also travel up north to the New England area a lot by plane and that is what really affected my carbon footprint. According to carbonfund.org, studies have shown that 30% difference of your mpg or kpl come from people’s driving habits. In order to reduce my carbon footprint I can suggest these tips to who ever is driving me. They can maintain a constant speed, drive the speed limit, and anticipate their starts and stops. Other ways that I could lower my carbon footprint are carpooling with people who live in my neighborhood, next time I go somewhere near my house I could ride my bike, or next time I have to go to the mail box or to a friend’s house that is close by I could walk instead of driving. By doing these things I hope that I can lower by carbon footprint.

    Hi, driving is a huge factor into why our footprints are so big. So many other countries went back to walking or using their bikes. The US is if not the number one, really close to the number one gas consumer. We always complain about traffic so why not leave our cars at home and walk? =)
  • Elena D-USA Elena D-USA Oct. 9, 2013
    Hi Helena! Transportation is one of the main contributors to my carbon footprint as well. Carpooling is a great way to save gas and if you could, you could even take a bus to school.

Lauren L-USA, Oct. 6, 2013

After being introduced to ISCFC last week, my class began to calculate our own personal carbon footprints. I found that my greatest source of CO2 emission came from my home. My total emission was 33736 lb, which compared to the national average of 53573 lbs is lower. And 13958 of these pounds came from my home CO2 emissions. In an effort to reduce my carbon footprint at home, I am going to make sure that all the lights and electronics are completely turned off when I leave the room. I am also going to encourage my family to try and use CFL bulbs instead of incandescent ones. Although CFL bulbs cost more than incandescent bulbs, they last up to 10 times longer. So, even though they cost more than regular bulbs initially, they can save you a lot of money and reduce your carbon footprint in the long run.

    Hi Lauren! I also found that a large chunk of my CO2 emmissions came from my home. I think your ideas are great ways to cut back on CO2 emissions. I also am working to be more conservative with things like water which I have a huge problem with using excessively! I really like the CFL light bulb idea and even though some people don't like the whiteness of the light, because it is different from the traditional incandescent light, I think it is really important to cut back so I will definitely be working to replace my incandescent lights with CFL lights.
  • Elena D-USA Elena D-USA Oct. 17, 2013
    Hi Lauren! I agree with you in making the transition from LED light bulbs to CFL bulbs. This can lower your electric bill and they last much longer than LED light bulbs. They are more expensive, but overall the cost will be cheaper because they are not used up as quickly and they use less energy. CFL bulbs are even brighter than LED bulbs! People should definitely make the switch.
  • Elena D-USA Elena D-USA Oct. 17, 2013
    So sorry but by LED I meant incandescent!

Rhianna R-usa, Oct. 6, 2013

Hi. My name is Rhianna. I am a high school student from Houston, Texas. When I calculated my carbon footprint, I expected it to come up as higher than the average for my region. Based on my input, my total footprint is 18981 kg of CO₂ per year, compared to an average of 24300 kg for Texas, USA, and 3791 kg (= 8358 lb.) worldwide. For my region, we give off about 6387 kg of CO₂. I give off 9115 kg this is most likely because I play sports and all of my games are a couple hours away. CO₂ given off from my home is 6893 kg while my region’s average is 9385 kg. My family and I are good about staying energy efficient. My average footprint for food is 2303 kg while my region’s is 5551 kg. This is most likely because I eat organically, locally grown food. My footprint for purchases is only 669 kg while my region’s averages at 2977 kg. I was surprised because I thought that I spent too much!

The only one of my averages that was above the normal for my region was that of transportation. An easy fix would be to carpool with people who are on my soccer team or are going to the same activity as I am. I already carpool with a senior and a freshman to and from school every day. I looked up the pros and cons of carpooling to see what others thought. The article was more directed at adults or older teenagers who have their license.

Carpooling is very beneficial for me. I don’t’ have a license yet and I don’t regularly have to run errands. I have a pretty predictable schedule so I can plan ahead for any changes in the carpooling times or pickup spots. For teens who don’t have a license, I can understand how it would be more sensible for them to carpool rather than for older, licensed drivers to carpool.

Anna C-USA, Oct. 6, 2013

After calculating my carbon footprint, I found that my highest total came from the home category, with 9080 kg per year. I feel that this is mainly a result of the light bulbs and light usage in my home. I counted a total of 75 light bulbs, 74 incandescent and 1 CFL. After questioning my parents about our lack of CFL light bulbs, I learned that the only one we had was from a school project in which each student at my sister’s school was given a CFL light bulb to try in their homes before purchasing many of their own. My dad expressed his discontent with the light bulb’s pricing and quality, so I did some research about CFL light bulbs.

To my surprise, I found many articles on the disadvantages of these light bulbs. First, there is the cost. After doing some online shopping, I found the average cost was about $3-$5 per 13 watt CFL light bulb and $1-$2 per 13 watt incandescent light bulb. It is claimed that CFL light bulbs will pay back this difference in the energy that they save and their longer lifetime, but this is only proven true in commercial and industrial cases, not residential.

The quality of light is also much lower in CFL light bulbs. In fact, the average incandescent bulb is 64.5% brighter than the average CFL light bulb. One would think that in paying more for a light bulb, you would receive a better quality of light, but CFL light bulbs provide less light than incandescent. The European Union, after putting a ban on incandescent light bulbs, even admitted that the quality of light produced by CFL light bulbs is exaggerated in claims by the manufacturers.
Because of these facts, my parents do not purchase CFL light bulbs for our home.

While I agree with them that they are not beneficial in price or quality, I would like to find a way to decrease my carbon emissions in the home category. I will do this by turning off lights in my home whenever they are not being used, but I know that using CFL light bulbs could make a much bigger difference in the carbon footprint of my home in addition to just decreasing light usage. What do you guys think? How can I reduce the carbon emission in my home without using CFL light bulbs? Or is the high price and low quality of CFL light bulbs something that I should look past due to their energy-saving qualities?

I was unable to attach more than one link to my post, so below are the links to articles on this topic in addition to the article already attached to my post. I used these articles in the statistics and information in my post, and they offer insight on CFL light bulbs and their disadvantages that goes even farther than what I have shared with you.

    I have mostly CFL lights in my house and I have definitely noticed a difference of light when I go to other people's houses! I don't really mind though. Concerning the price, don't CFL lights use less energy and therefore lower your energy bill? In this case, CFL lights may save you money in the long run
  • Anna C-USA Anna C-USA Oct. 6, 2013
    Nora - I believe you're right that it is advertised that CFL lights will save money in the long run. However, according to an article attached to my post (http://edisontechcenter.org/CFLs-Rick.html), they are much more likely to save money in a commercial or industrial use, rather than residential. This video (http://www.youtube.com/watch?v=oKu6YZra5KQ) talks about how the amount of money you will actually save when using CFL light bulbs differs depending on where they are and how much you use them. To sum up the video, a CFL light bulb will save money if it is used for many hours and a long time, but not if it is used in small amounts. Perhaps this shows that it just depends on the household and habits of your family.
  • Olivia BH-USA Olivia BH-USA Oct. 10, 2013
    Thanks for your post! I didn't realize that the EU had put a ban on incandescent light bulbs, and I also did not realize that the issue of amount of light was such an issue when deciding between incancdescent and CFL.
    Personally, I think it is worth the money to use CFLs for their energy saving qualities since lights are some of the most common things we use everyday and can really add up in terms of energy and, consequently, carbon footprint. In my own home, we use almost entirely CFLs, though we used to have some incandescents. In my experience, CFLs do not offer necessarily offer a less bright light, just a different type of light. I think of CFLs as offerring a bright, white light that is more focused where as incandescents provide a light that spills out into a room. Incandescents can definitely light a large room better, but for things like reading lamps or in rooms with more than one light, I think CFLs work great without losing that much light quality. It is simply a matter of adjusting to the different type of light.
