From AFP (in french), these pictures are thermal images taken from a plane and then used by the french city of Reims to spot poor building thermal insulation and inform their owner about relevant technologies and possible tax breaks in the french context.

Looks like to me a cheap and efficient way to change citizen perception of energy, global warming and what can they do about it by themselves (and probably save money).

I'm curious wether it was tried in other countries, any suggestion?

The energy big picture

Energy is used for:

• heating/cooling at home and work
  
• transportation
  
• industrial processes (eg: aluminium, computer farms)

Energy may be transported (usually as electricty) or transformed for storage, this imply:

• energy transportation losses (electricity grid, heat pipes, moving wood around)
  
• energy transformation losses (hydrogen generation, fuel generation process)

Energy sources are either:

• renewable (eg: wood, wind, water)
  
• nuclear
  
• non renewable (coal, gas, oil)

Non renewable are also used for:

• agriculture (fertilizers)
  
• materials (plastics)

I don't have numbers handy, but I hope ET'ers will help put numbers in those categories. Here we're talking about heating/cooling and probably a bit of energy transportation.
