Nanotechnology operates at such a fundamental level that there is very little of a technological nature that it will not impact. Thus its effects on energy generation, transmission, storage and consumption are numerous and diverse. Some will be incremental and some quite possibly revolutionary.

So, greenhouse nightmare or an emission-free future? Nanotechnology can enable them both. Barring a global wave of forward planning unseen in mankind's history, economics will probably make the decision for us.
