CO2 calculations - part 2

Blog contents: You may have noticed that I have added some references to other websites and blogs on the righthand side of the blog. I hope you too will find them interesting.



Progress:
Today it went from bad to near-disaster in what used to be our Biliard-room (now our ventilations room). The picture shows the new piping in the ceiling - and believe it or not, they still haven't finished installing stuff in this room (one more fan and two more pipes).

There was also some good news when I came home from work today - the heatpump had been put where we wanted it. We had to pay 500 USD extra for the pump (incl. the installation job) that moves the condensated humidity from the heatpump to the drainage point.








Your own CO2 emissions:
A Audi A4 car sends out 0,197 kg CO2 into the atomspere for every kilometer you drive (http://www.vegvesen.no/). Total emissions during a trip from Oslo to Trondheim and back = 1000km *0,197kg/km= 197 kg CO2

To save 30 tons of CO2 per year (the yearly savings of our JAHUS project, see the blog-post yesterday) - you would have to cut the driving by: 152.000 km !

Most people don't drive that much during a year. A reduction of 5000 km or approx 25% of a normal family cars yearly distance (by using bicycle to work and walking to the grocery store) is more realistic => ca 1 ton CO2

A traditional american diet results in almost 1,5 tons more CO2 emissions a year than a vegetarian diet (with the same number of calories). Converting to a vegetarian diet saves an additional 1.5tons of CO2 per person. With a household of 5 people the savings = 7.5 tons CO2

Drop the 2 trips we (parents only) fly each year to the southern part of Europe. Each person saves 2,6tons of CO2 by not flying to Rome/Italy and back to Oslo - so the total savings is ca 4 * 2,6 = 10,4 tons of CO2

Yes, you can (and should) also do minor things such as limiting the use of warm water for showering, replacing old light bulbs with energy-saver/LED light bulbs, and changing to light bulbs that automatically get switched on when it gets dark and off in the morning.

Add the effects of all the above mentioned measures and we'll still be 10 tons short of matching the estimated savings of 30 tons CO2 associated with our JAHUS project (with no negative effect on lifestyle or comfort). What would you rather do?
