Not necessarily true. What if the resources consumed to create the material are high and the lifetime of the material is short? Unless the total life cycle of the product results in a lower consumption of resources over its competitors the product is fun from a technology standpoint but has no place in general use.

Hey, its good to see someone thinking about lifecycle analyses.

Earlier solar panels produced a net loss (0.1%) in energy when looking at the fuel used to mine the oars, the cost of fabrication, transportation, lifetime, and efficiency.

Hopefully we'll have a real winner on our hands this time around, always keeping in mind the process from development to decommissioning
