We should learn from the past. It’s not a cliché,not like talking about Romans. There was a time when people was able to do better with less. That’s the way a social and economical crisis should be handled.We had our Industrial Renaissance, even if we are not always aware of it.In the 50’s we came out of a war, we started building highways: they connected people and ideas. That’s great but nowadays there is a price to pay. We want to pay this price by wind and sun. It’s not a cliché: it’s a solution, it is easy and for free.
