Update: The final challenge statements for Negawatt Rio. More information could be found through #NegawattRio

Since 2012, Brazil has been contending with a developing crisis that is causing two major nation-wide problems affecting millions of Brazilians primarily in large cities like Rio de Janeiro: 1) the lack of water as the reservoirs of Brazilian capitals reach dangerously low levels, and 2) exposed frailties in the energy system which have resulted in blackouts across 11 states. Around 80% of Brazil’s electricity comes from hydropower; the system was severely strained as 2015 began with one of the hottest and driest months since measuring began in 1917. The levels of water at the reservoirs that help supply energy to half the country have dropped to critical levels. At the same time, the consumption of water and energy has spiked. While alarming, Brazil’s current energy crisis creates an unprecedented opportunity for the creation of new hardware, software, and business model solutions to increase urban energy efficiency in an open, collaborative and multidisciplinary way.

Rio de Janeiro is one of the central players in this unfolding national drama - not only as a result of its global prominence in the face of mega events like the World Cup and the Olympics, but also as one of the top population and economic hubs of the country. In addition, the city offers a very promising reason to hold Negawatt’s global innovation competition: its position as a technology and innovation leader in South America with an ecosystem of innovative, tech-driven entrepreneurs and tech hubs to help identify and adapt technology and business innovations that have the potential to transform Rio de Janeiro - and potentially Brazil - into a more sustainable and energy efficient place.
