The “Bein’ Green” song was written in 1970 and sung by Kermit the Frog in the first season of Sesame Street. Since then, it’s taken on a life of its own. Frank Sinatra did a version of it in 1971 on his Sinatra & Company album and many other artists have performed it. In recent years, it’s been picked up by the environmental movement, given its obvious connotations. It’s even been used in an EDF advert last year.
Those immortal words take on new meaning these days, when the difficulty of being green is all about how we can act in a way that doesn’t harm the environment. This is often made difficult by apparently conflicting information. For example, do I throw out my old fridge because it’s inefficient, or do I use it till it falls apart? If I throw it out I can save energy with a newer model, but I create more waste (even if it can be recycled) and another fridge has to be made to fulfill my needs. The British alone throw out about 3 million fridges per year, so this is not a trivial concern.
I looked it up on google. It seems that fridges manufactured in or after 2000 shouldn’t be replaced for some time yet. Fridges purchased in or before 1985 definitely should be replaced, as replacing them could pay you back in less than 2 years in savings on your electricity bill. Between 1985 and 2000, it’s not so clear cut. Many domestic appliances didn’t have an energy rating until the early 1990s, but a fridge in good condition may still have life left in it.
So how do you know if you should throw your fridge out or not? For the purely financial aspect of saving energy, there’s a calculator at www.energystar.gov that can help you decide. Unfortunately, it’s tailored to the US market, so europeans will have a harder time using it. You can take a more direct approach, and actually measure the consumption of your current fridge, and compare it against other models.
Tom Harrison has a really informative blog (“fivepercent”) which illustrates the effectiveness of this approach. He has reduced his electricity use by 50% in 4 years, and his use of water by a similar fraction. One post refers to measuring power consumption minute-by-minute using a Cent-a-meter, so you can see which devices are really responsible for your consumption. This gadget works for US and european voltages, and Tom estimates that it can pay for itself in less than a year, even if you are already frugal with your electricity.
Toms approach to everything illustrates the importance of actually measuring the things you are trying to save money on. You could simply do some of the right things, like turning off lights in empty rooms, but when you measure your use of electricity (or water, petrol, etc) you will learn just how effective you are being. I have done this myself with my petrol consumption, and I can testify that it is a powerful incentive to save more. I’ve also started tracking my use of water and electricity by reading my meters regularly. Not as precise a method as Tom, but it’s a start.
The cold weather we have experienced recently has caused record demands for electricity (about 92,000 MW), and EDF announced that they may introduce power-cuts to save electricity. That peak could be eliminated by savings of 10% or more per person, which would mean no power cuts would be necessary. 10% is not much to ask for, even Tom managed to find an extra 10% after four years of actively trying to save electricity!
Maybe it’s not so hard to be green after all…

La chanson «Bein’ Green» («etant vert») a ete ecrit en 1970 et chante par Kermit le grenouille dans la premiere saison de 1 Rue Sesame. Depuis, ce chanson est devenu populaire. Frank Sinatra est parmi un bin nombre d’artistes qui l’ont chante, lui en 1971 dans son album Sinatra & Company. Aujourd’hui, la question d’etre vert a pris une dimension environmentale. Bein’ Green a donc servi dans une pub EDF l’annee derniere.
Ces mots ont pris une importance tout a fait different ces jours, quand la difficulte d’etre vert concern plutot la maniere dont nous affectons l’environnement. Ceci est souvent rendu plus difficile par des conseils apparament contradictoires. Par exemple, dois-je jeter mon ancien frigo parce-qu’il n’est plus efficace, ou dois-je le garder jusqu’il tomb en panne? Si je le remplace avec un model neuf et efficace, j’utilise moins d’electricite, mais si je le jete trop tot je cree des dechets pour rien. En grande bretagne on jete a peu pres 3 million frigos par an, donc ce ne pas une question sans importance.
J’ai recherche la reponse sur google. Il parait que des frigos datant de 2000 et plus sont a garder. Avant 1985, c’est a remplacer toute de suite, vous pouvez vous rembourser le prix de remplacement en 2 ans avec la reduction de consommation electrique. Pour des frigos qui date entre 1985 et 2000, la reponse et moins nette. La plupart des appareils domestique n’avait pas d’indice d’efficacite avant les annees 1990, mais un frigo en bon etat pourrait toujours servir de maniere ecologique.
Donc, comment savoir si on jete ou non? Pour l’aspect financiere tout seule, il y a une calculatrice a www.energystar.gov qui pourrait vous aider. Helas, c’est concu pour le marche americain, donc les europeens auront des difficultes de s’en servir. Il existe un method plus direct, mesurer directement la consommation de votre frigo, et puis faire la comparaison avec d’autres modeles.
Tom Harrison a un blog tres informatif («fivepercent») qui demontre l’efficacite de cet idee. Il a reduit son usage d’electricite par 50% en 4 ans, et son utilisation d’eau par a peu pres la meme quantite. Un de ces articles parle du faite qu’il a mesure sa consommation d’electricite en temps reel avec un «Cent-a-meter», qui permet de voir tres vite quels sont les apareils qui en consomme le plus. Le Cent-a-meter fonctionne aussi bien en europe qu’aux etats unis, et d’apres Tom il peut se rembourse en moins d’un an, meme si vous etes deja tres economique.
Les resultats de Tom demontre l’importance de mesurer les choses qu’on veut ameliorer. On pourrait tout simplement faire des bons gestes, comme eteigner les lampes dans des pieces vides, mais quand on met des chiffres a la consommation d’electricite (ou de l’eau, de l’essence etc) on apprend pour de vrai jusqu’a quel point ca marche. J’ai fait pareil moi-meme avec ma consommation d’essence, et j’ai trouve que ca m’inspire de faire meiux, je veut toujours battre mon record. J’ai aussi commence a suivre mon usage d’eau et d’electricite en faisant note de mes propres compteurs. Pas aussi precis que Tom, mais c’est un debut.
La vague de froid qu’on a eu dernierment a battu le record pour la consommation d’electricite en France (environ 92,000 MW), et l’EDF a annonce qu’ils pourrait etre force de couper l’alimentation d’une maniere controle. Ce record pourrait avoir ete elimine si on consommait tous 10% de moins, et on plus les coupures seraient evite. 10% n’est pas beaucoup a demande, meme Tom a reussi a trouver 10% de plus apres quatre ans d’effort.
Peut-etre qu’apres tout, ce n’est pas si difficile d’etre vert…

We have been “upgrading” our home slowly and piece by piece for years now to lower the electricity consumption among other things. When we did the kitchen we have the old fridge (from -94) to a club that we belong to, that way it’s still in use but only for a day or so now and then. It feels so much better than simply trashing it.
I like the Cent-a-meter since it shows clearly what change you are making. Sometimes it feels somewhat frustrating when you try to lower the consumption of electricity but the bill is still at the same price. It’s of course the cost of electricity that’s going up in a steady pace that’s causing it, but it also make it hard to really see the difference.

Hi Sanna,
that sounds like a smart use of an old fridge, good thinking.
Even without a cent-a-meter, just reading my meters every weekend makes me more conscious of my use of electricity. I’m curious to find out how much I really do use, I’ve never known before. Our bills are normally based on estimations, so looking at old bills doesn’t tell me much.

it’s the same over here. With all the global warming going on, winter’s are colder and the summer’s are hotter. So in winter our gas (heating) consumption is higher and in summer our hydro (electricity for air conditioners) is also higher, it’s a no win situation.
thanks for commenting on my blog, and the letter I have assigned you is “N” I hope that is okay?

Hi Gill,
“N”. Hmm, one easy one comes to mind. I’ll see what I can do with it, may take me a few days!
