Of the many stories I heard about the drought while I was in Brazil earlier this month, one stands out: a colleague was riding the elevator in her building and saw a note from a concerned neighbor. “Dear neighbors,” the note read, “As you know we are in a severe crisis. Everyone must do their part to conserve water. That is why I have decided to only wash my car once per month. I hope everyone else can make a similar sacrifice.”
I had just spent five days in Sao Paulo, visiting electric utility executives to imagine how software technology could better engage their consumers toward addressing the deepening crisis. Twenty million people live in Sao Paulo, which is suffering its worst drought the metropolis has seen in nearly a century. A couple of weeks earlier, during Carnival, some towns in the region had canceled street parades for fear there may not be enough water to clean the streets or cool down the crowds. Officials from Sao Paulo’s water utility, Sabesp, had already begun rationing water.
The last time Brazil faced a water crisis of this magnitude, a small private utility – the Sao Paulo Railway and Light Company – was at work constructing the foundation of a modern infrastructure to supply water and power. Today, Brazil’s system of reservoirs and dams provide not just drinking water; they supply more than three-quarters of its electricity generating capacity. So as the Cantareira’s stores fluctuated like a dollar stock – dipping to just five percent of capacity in early February – Brazil’s utilities braced for an energy crisis.
