Zeta Communities, a manufacturing start-up, plans to mass-produce energy efficient homes to give an affordable option home buyers wanting to invest in ultra-efficient multifamily housing.

The most efficient buildings are dense multipurpose structures like skyscrapers, which minimize material, heating, and cooling. Single-family suburban houses are inefficient since they need to be individually heated and cooled, and are spread out from the population, encouraging driving more.

The solar manufacturer 1366 Technologies announced a new 18% efficient photovoltaic cell that utilizes two new breakthroughs of light-trapping honeycomb structure and minimal shading from front-side metallization.

Programmers and hardware designers look for energy efficiency solutions as data center energy use continues to climb.
