The super-efficient 'factor 10' society

At Leonardo ENERGY, we're starting a reflection about the elements of the super-efficient society. Many of you will have heard of Factor 4, and the derived Factor 10 or even Factor 20 schools of thought. In the milestone book 'Factor 4', many solutions are more like an incremental improvement than a step change.

The building blocks of the super-efficient society can be technological, but behaviour change and organising society to use combined techniques are equally important.

So, for starters, here's a list of factor X solutions, but I'm sure to have missed out a lot and welcome your comments:

• low energy / passive / zero energy homes

• leds

• electric vehicles

• compact cities

• teleworking

• bicycles
