The Nurture keeps users in check when it comes to their energy consumption. The system works by symbiotically attaching the user's consumption with the amount of water their plants will receive.
The Nurture system is set up to show that energy consumption affects other things around the user in certain ways. When the user is using too much energy, their plants will suffer for it by not receiving the amount of water they need to survive. On the other side of the coin, if the user keeps their energy consumption down, their plants will be properly watered.
By keeping one's plants alive through prudent energy saving tactics, users are also saving the planet.
