Carbonnation - The Movie. Energy Information. We launched Google PowerMeter as a free energy monitoring tool to raise awareness about the importance of giving people access to their energy information.
PowerMeter included key features like visualizations of your energy usage, the ability share information with others, and personalized recommendations to save energy. We partnered with device manufacturers and utilities around the world. Many of our partners now have new options available for accessing energy information.
