One Block Off the Grid took a stab at answering the question: “How big a backyard do you need to live off of the land?” It turns out, plants like corn, wheat, fruits, grains, and vegetables take a lot of space.

Michigan-based Great Lakes Electric has a solar hot water product with evacuated tubes that allows for creative building-integrated solar hot water. By releasing the restriction of roof mounting, as with typical solar hot water products, GLE’s unit allows for more innovative placement and ends the worries of roof penetrations and units looking like large black rooftop tarps.
EV owners benefit from an efficient engine and a domestic energy source; however, the energy source will likely be electricity derived from coal and natural gas and maybe a little bit from nuclear and renewable sources like hydro, solar, and wind. To improve this, Ford and SunPower Corp. today announced a new initiative called “Drive Green for Life” to offer solar power to purchasers of Focus Electric and the C-MAX Energi plug-in hybrid vehicles.
Research suggests that homeowners with solar PV will recoup the cost of their solar investment upon sale of the home. Homes with PV systems sell for a premium over comparable homes without PV systems, according to a study of home sales in California from 2000-2009 by the Lawrence Berkeley National Laboratory.
The biennial Solar Decathlon is fast approaching as teams across the world prepare their solar-powered home for West Potomac Park in Washington, D.C. The competition is a showcase of modern, efficient homes from 20 teams held September 23 – October 2, 2011. We’re going to start our coverage this year with a look at the models as displayed at IBS 2011 in Orlando a few months back. Which do you want to see in real life?
