As well as the formal paper there is a sixteen slide show.This is an idea worth exploring. There are obvious problems with privacy, as there were with the previous computer labs tracking devices. However, as anyone who has read the draft energy audit standards knows, the state of the art in energy measurement for carbon auditing is not very advanced. Therefore the information needed from a personal tracking device need not be very precise. Also gaps in measurements can be tolerated far more than with a security tracking badge.
Abstract. Every day each of us consumes a significant amount of energy,
both directly through transportation, heating and use of appliances,
and indirectly from our needs for the production of food, manufacture
of goods and provision of services. I envisage a personal energy meter
which can record and apportion an individual’s energy usage in order
to provide baseline information and incentives for reducing the environmental
impact of our lives. Contextual information will be crucial for
apportioning the use and energy costs of shared resources. In order to
obtain this it will be necessary to develop low cost, low infrastructure
location systems that can be deployed on a truly global scale. ...
