WattzOn allows you to measure the amount of power needed to support all of the aspects of your lifestyle. By calculating every impact in watts, all the varied choices made in your life can be directly compared - including actions that happen on markedly different timescales. Measuring in power rather than carbon emissions also recognizes that there are not enough remaining fossil fuel sources to support the energy needs of the world. Not limited to activities, you can also determine the impact of your belongings through the embodied energy database. WattzOn is opening up the assumptions, the methodology, the mathematics, and the data to the entire community -- we can argue, modify, tweak, and eventually reach consensus so that WattzOn's power estimates improve over time.
