Greenely is the next generation energy management tool. Using the Greenely mobile app, households will be able to get an overview of their energy consumption and personalized feedback on their energy behavior, all with minimum effort and with no additional hardware installation. The tool utilizes learning algorithms that track and analyze the households’ energy behaviors and then adapts accordingly. Through in-depth and targeted analysis, gamification and comparison with neighbors, the households will be incentivized and guided towards a decreased energy consumption.
