This article is brought to you by: www.treehugger.com. I had my own blog written this morning about 6 energy tips to lower your bills this winter and then found this great article with everything all in one place!! So, here it is….
Heating, cooling and lighting our houses belches out a third of our carbon dioxide and sucks a lot of money out of our wallets in the process. There are so many guides and websites that tell you what to do fix this from insulating your walls to changing your windows. But if you are into frugal green living, what should you do first? What is the most effective thing to do? What gives the most bang for your buck?
A few years ago the Rocky Mountain Institute came up with the Cool Citizens Guide where they not only suggest what should be done but they calculate a cost per ton of carbon saved so you can tell what is the most effective place to put your money. It isn’t a new document and we are talking 1992 dollars, but it is the relative cost per ton saved that is important. It is old enough that some numbers are probably off; changing bulbs to CFLs is relatively expensive, as electricity was cheaper then and bulbs a lot more costly.
For example, changing windows is expensive and costs $133.88 per ton of carbon saved; changing to a programmable thermostat is cheap and comes in at $ 9.34 per ton of carbon saved. So before the vinyl window salesman tells you to fix your windows, do all of the cheap and effective stuff first. second- do all the free and effective stuff first:
1. Lower water heater temperature to 120°F
2. Lower AC thermostat by 3°F- greendailygrind comment: by lowering your thermostat by just 1 degree, you will save 3% in home energy costs. 2 degrees saves 2,000 pounds of CO2 emissions over the course of a year!
3. Wash clothes in cold water
4. Air dry clothes during summer
5. Turn off unneeded lights
Just doing that will save 1600 tons of carbon and $250 per year.
6. Get a Programmable Thermostat: $9.34 per ton CO2 saved
a setback, or programmable thermostat has the biggest bang for the buck of any single thing you can do; it costs only $9.34 per ton of carbon saved, and is getting better all the time as the price of the electronics drop. A setback thermostat can save up to 15 percent on your heating bill.
For houses with radiant floors or old hot water radiator systems, there is a really slow response time because of the thermal inertia in the systems. I used to say that setbacks wouldn’t work for these, but new thermostats track the performance of your heating system, figure out when to turn it on, and basically plan ahead. After all, nothing makes you want to jump under the covers than a cool house before you go to bed!::More
7. Stop the Air Leaks: $10.77 per ton CO2 saved
Next up on the RMI Guide is to seal large air leaks, cheap to do (mostly labor, minimal materials), costing a mere $ 10.77 per ton of carbon saved. In an old, pre-1945 house, the air leaks can add up to the equivalent of a hole in your wall 21 inches in diameter! Natural Resources Canada (NRC) says that in a house vintage 1946-80 the hole is 16 inches, and in a modern conventional home, 14 inches. When you think about it that way it becomes obvious that there is a lot of heat loss, it is like leaving a window open all winter. ::More
8. Insulate Your Water Heater: $12.66 per ton CO2 Saved
Here we have a really easy one, that costs only $ 12.66 for every ton of carbon saved. You can buy kits at hardware stores or the big boxes like Home Depot or Lowes, that come with straightforward instructions. ::More
9. Add Attic Insulation: $ 15.56 per ton CO2 Saved
Many houses have attics that are accessible via a hatch in the hall or a cupboard; if you have this, insulating your attic is not that hard, and delivers a good bang for the buck; RMI estimates it will save you 2,142 pounds of CO2 per year, at a cost of $15.56 per ton. We think R-50, or about 16″ of glass fiber insulation is a good target. Glass fibre is cheap, relatively easy to install, and noncombustible, so we will look at that first but it is not your only option. ::More
10. Install Efficient Showerheads: $18.02 per ton of CO2 Saved
Almost as easy as wrapping your water heater, changing your shower head costs only $18.02 for every ton of carbon dioxide saved, and saves you $21 per year. The U.S. Environmental Protection Agency (EPA) notes that showers use about 17 percent of residential water use, totaling 1.2 trillion gallons per year. ::More
11. Weatherize Your Windows: $25.02 per ton of CO2 Saved
If you live in the north in a drafty old house, this is an important one. The window salesman may tell you that you have to replace those old wood windows, but they are often part of the character and charm of the house, the replacements are usually vinyl, and it costs a lot of money.
RMI suggests that weatherizing your old windows will save 621 pounds of carbon at a cost per ton saved of $25.02; I suspect it is much more money saved than that. These instructions are for double-hung windows, but they work for most kinds. The products I use are a seal and peel caulk (wonderful stuff; no matter how bad you are at caulking it just peels off in the spring) and heat-shrinking film. I lust after magnetic interior storms but that is more expensive. ::More
12. Install Faucet Aerators: $27.27 per ton of CO2 Saved
After spending the weekend winterizing our windows, next up on the RMI list is dead easy by comparison and cheap too; saving $6.22 and 110 pounds of carbon, at a cost per ton saved of $27.27. I am frankly surprised that such a little step does this much at all, but by mixing air with water you use less water and that means less water heating.::More
On a bang-for-your buck basis, it all goes up from there.
It doesn’t mean you shouldn’t do them; some are cheap (like cutting phantom power loads in half, costing $128 per ton but cheap to do) and some are really expensive and not that effective (like adding low-e films to existing windows, topping the list at $241 per ton of CO2 saved). It is not always intuitive, but it is useful if you are trying to live a frugal green life.
It is so funny to hear people talk about bottled water … Especially, because I was one of the largest consumers of bottled water. That was all I drank … all day long. My largest monthly expenses were probably my house, car, food and then water. After hearing about all the misconceptions about bottled water and reports that it is not as clean as we think it is, I decided to make a change. Now that my huge monthly expenditure of bottled water was going away … I invested in a reverse osmosis and Klean Kanteens for the family. Let’s just say that this tip on going green has saved me a tremendous amount of money. Americans currently spend over $8.6 billion dollars a year on bottled water.
One big misconception is that bottled water is safer than tap water. That is not necessarily the case. In the United States we have some of the safest tap water in the world. As much as 40% of the bottled water sold in the United States in just filtered tap water anyways. If you check the labels on the water you buy, look for “municipal source” or “community water system”. Plus the EPA sets much more stringent quality standards for tap water than the FDA does for bottled stuff.
One big reason to stop drinking tap water is the expense. Tap water costs about $0.002 per gallon compared to the $0.89 to $8.26 per gallon charge for bottled water. If we spent that much money on our tap water, we would be looking at a $9000.00 monthly water bill. Most of us are spending more on bottled water than we spend on gas per gallon for our cars. People were terrified when the price of gas was over $4.00 a gallon, but have no problem paying more than that for something we can get right out of our sink.
Did you know that 88% of empty plastic water bottles in the United States are not recycled? The Container Recycling Institute stated that plastic water bottles disposed of (not recycled) are at the rate of 30 million bottles per day. That is an astounding number of bottles that enter our landfills. Here is the crazy part … it would take 450-1000 years for a plastic water bottle to biodegrade … BUT … if it enters the landfill it does not have the sun and air to decompose, so it will be there forever.
According to the NRDC … City tap water can have no confirmed E. coli or fecal coli form bacteria (bacteria that are indications of possible contamination by fecal matter). FDA bottled water rules include no such prohibition (a certain amount of any type of coli form bacteria is allowed in bottled water). Any violation of tap-water standards is grounds for enforcement — but bottled water in violation of standards can still be sold if it is labeled as “containing excessive chemicals” or “excessive bacteria” (unless FDA finds it “adulterated,” a term not specifically defined).
There are many studies concerning the evidence of Bisphonel a (BPA) found in the water from plastic water bottles. The plastic bottles can leach chemicals into the water if left in the sun, heated up, or reused several times. You can read on the side of some water bottles and it will say “one time use.” Did you know that it takes about 17.6 million barrels of oil (not including transportation costs) to meet the needs of bottled water? That equals the amount of oil to fuel one million vehicles in the United States each year.
So the question is … Are you going to continue to drink bottled water?
