Specific contribution of activities paper

Keep calm and have a cuppa

This paper uses regression techniques to pinpoint which activities cause most electricity demand. Here is a surprise: even though having a cup of tea requires energy, having a hot drink slows us down enough to result in a net reduction during that hour. Next time we face a blackout, have a tea and read the paper.
