Door knocker
Writing your first blog is never easy. What should it be about? Renewable energies are booming worldwide and new and hip sustainable gadgets are released on daily basis. There are simply too many to choose from. However I do like this urban turbine from the Netherlands. Sturdy and simple design, unlike many of its predecessors this one might actually work!
But let me start my first blog with someone who inspired me during my first years as a consultant in renewable energy: Ad van Wijk. Building a big renewable company (Econcern) and then seeing it going bankrupt must have been hard on him. In the years before bankruptcy I learned from him not only to think big, but to think both big and small. He was one of the persons responsible for the first ever non recourse financing for an offshore wind farm (Prinses Amalia wind park).
All nice and well, but when he gave a presentation to the company he would rather talk about how to cook a potato, or why door bells are stupid. Did you know that most door bells use a tiny amount of electricity all day, just waiting for you to press it? Silly if you think about it from an energy efficiency point of view. Why not supply it with a small solar cell, that’ll safe you on wiring too! Or even better, use an old door knocker?
Taking small things like this seriously can really help to reach Ad van Wijk’s life goal: a sustainable energy supply for everyone. However you can also take things too serious, have a look at this.
