Google is very much working on ways to stimulate conservation of energy. One of the issues they mention on their blog is that by giving feedback to people it is possible to save lots of energy in homes and offices. Some time ago I was involved in a research study where we looked at research worldwide on this subject. One of the most remarkable ones was a study done in Stavanger, Norway. There it turned out that just by changing the period after which people settle their energy bill (you get a bill every month normally but only once a year the energy company checks if the bill is the same as the real (average) use during the year). They changed the period from one year to two months (meaning the amount used was checked bi-monthly and the bill adapted accordingly). The energy use of households after this went down 8%. Because of the bi-monthly check people where immediately reminded that energy costs a lot during winter. With some extra data the savings grew to 12 to 16%. This feedback on use can be more fine-grained. At home I am ...

We all know we have to be very careful with energy due to the warming up of our planet, dependency on energy from areas in the world you do not want to be dependant on and other reasons. But we also know that it is very hard to find the incentives to stimulate people to save energy here and now. Problem is that there is too much of a time lag between the action to save energy and the advantages acquired. Recently I held a key note presentation at the conference "Greening the enterprise 2.0", focused on how to save energy in office environments. Especially in offices it is hard to stimulate people to save energy because they do not have to pay the energy bill themselves. Automatic systems are usually circumvented (people open windows in completely controlled buildings because the intelligent control mechanism for temperature is less intelligent than the maker thought) and therefore seldom delivers the result that we think of beforehand. And people are lazy. The picture on this post is from my own re-chargers in my office. I once placed a switch there to ...
