I believe that participatory design, e-democracy and crowdsourcing is the way to redesign our cities. This is why I am also pushing my graduation project towards this direction. I believe that local, social support can celp to reduce our domestic energy consumption. There are already wonderful tools to use and base my research on, without having to start from the scratch. One of them is diycity.org, where I just started the DIY, Delft.
If you live or study in Delft, join the group and lets explore solutions for how we can reduce domestic energy consumption (as a start 😉 )
