Nuage Vert

Nuage Vert the industrial size art installation and visualisation over the centre of Helsinki over the Ruohlahti power station came to the end in February.

The artwork not only was a visual success but some data from Helsinki Energy shows it was effective in reducing consumption so well done to them.

Helsingin Energian tutkija Jussi Palola kertoo:

Kuormitus väheni 2 MVA 29.2.2008 kello 19-20, normaaliksi vertailuarvoksi sain tuolle ajanjaksolle (perjantai-ilta 19-20) 1,2 MVA, joten Vihreä Pilven vaikutus voisi olla täten 800 kVA.

Again we come to the inevitable conclusion that all homes should show their owners exactly what energy they are consuming and how fast they are consuming it.
