Harold Turner’s home near Concord, New Hampshire measures 3,370 square feet and was built using the ROSE construction method, which was created to build affordable net zero energy and cost effective homes in a wide variety of geographical locations and environments. R stands for “Renewable energy production,” O and S stand for “Owner driven spatial design,” and E is for “Energy efficient construction,” while the entire house is known as ROSE cottage and serves as a prototype and test bed for future homes to be built using this method. The entire home was built for $175 per square foot.
While living in solar powered homes is very sustainable and environmentally friendly, the materials from which most solar PV arrays are constructed are not. Since they are often made from rare natural materials or plastics, researchers are constantly looking for way to improve this flaw and make the whole package more eco-friendly. A team of scientists from the University of Maryland, the South China University of Technology, and the University of Nebraska-Lincoln have recently developed a type of paper, which is made from wood fibers. This paper is 96 percent transparent and could conceivably one day be used instead of the plastic materials used to construct the solar cells of today. This would make solar cells more eco-friendly as well as much cheaper.
The Santa Monica-based award-winning green design studio Minarc partnered up with Habitat for Humanity, and a local non-profit firm Restore Neighborhoods LA to design and build affordable, net-zero energy prefabricated homes in the low-income areas of South Los Angeles. Together they built 3 homes, which were all built on vacant lots in the poorest neighborhood of South Los Angeles. The houses all feature Minarc’s innovative, interlocking panel system, which is called mnmMOD. The homes are also equipped with roof top mounted solar panels.
A single family home in Glencoe, Illinois recently received the LEED Platinum for Home certification.

The premade container home maker Cargotecture now offers a prefab home that is a perfect way to downsize yet retain the comforts of living in a larger space. The c-series 640 Lookout model measures 640 square feet, and features a large living area with a kitchen, a spacious bedroom and bathroom, a media room and a lofted sleeping area for guests.
On January 1, 2014 the federal ban on manufacturing 40- and 60-watt incandescent bulbs went into effect. One of the main implications of this ban is that consumers are slowly going to be forced to opt for LED or CFL light bulbs. However, the shape, cost and light quality of LED light bulbs has not made them very popular with consumers thus far. Philips aims to change that by releasing an innovative LED light bulb, which is called SlimStyle, retails for less than $10 and is flat.
