The roll-up of energy-efficiency start-up companies by large energy services companies like Schneider Electric is largely resulting from the structure of the market more than anything else.

This weakness is caused by defects forming in their crystal-lattice structure, which in turn are caused by high-energy particles such as neutrons bumping into individual atoms and knocking them out of place.

Like Moscow's two-strand Siberian gas pipeline deal in the early 1980's, the Cienfuegos complex is an unprecedented "national project" with potentially decisive implications for the country's long-term energy viability, hard currency earnings structure, attraction of other foreign direct investment, access to international financial institutions and, of course, nationalistic pride.

Imagine a lowly rated energy bond and top-notch bank paper in the same structure.

One reason is that MLPs allow some energy companies to structure themselves in a way that attracts conservative, long-term investors rather than speculators that is, as income investments rather than capital-gains plays leveraged on commodity prices.

Hovering close to the ground, each of these thin-shell dwellings is made entirely out of a single concrete slab stretched out to create an energy efficient structure that is environmentally greener than traditional construction methods and cheaper and faster to produce.
