Technology that streamlines the deployment of residential solar + energy storage without compromise of performance or cost
Nichola Groom, Reuters: Tesla's SolarCity reported a drop of nearly 40 percent in solar installations for the first quarter on Wednesday, the latest sign of a reversal in fortunes for the once high-flying residential solar industry.
Megan Barber for Curbed: Based off the concept of how a sunflower follows the sun, the Smartflower is a portable, adjustable petal system that tracks the sun's path throughout the day. When the sun rises in the morning, the Smartflower automatically unfolds and begins producing energy by setting its petals at a ninety-degree angle. The flower goes "back to sleep" into a folding position at night or whenever high winds make it unsafe to operate.
Brad Plumer for VOX : Rooftop solar is expanding rapidly in the United States — by some estimates, a new system goes up every four minutes. There are plenty of reasons for that, from falling prices to generous federal subsidies to innovative leasing schemes. But there's another, little-discussed factor here: Residential solar power is contagious. Yep, contagious. Studies have found that if you install solar photovoltaic panels on your roof, that increases the odds that your neighbors will install their own panels. SolarCity, the largest solar installer in the United States, just published some fascinating data on this "contagion" effect. The company has installed 230,000 rooftop systems nationwide (often by allowing customers to lease panels rather than buy them upfront). It says fully one-third of customers were referred by a friend or neighbor. SolarCity has also made some neat animations showing the "contagion" effect in action. View here:
By Daniel J. Graeber for UPI.com: Small-scale solar installations in the United States account for about a third of the overall capacity on the grid, a report from the federal government said. The U.S. Energy Information Administration estimates total U.S. solar-power output in September, the last full month for which data are available, at 3.5 million megawatt hours. Of that, just more than 30 percent came from small-scale solar installations. "Generation from roof-top photovoltaic systems has become an increasingly important part of total solar generation in the United States," EIA AdministratorAdam Sieminski said in an emailed statement. A September report from the Solar Energy Industries Association, with support from green energy market adviser GTM Research, found second quarter residential solar capacity grew 70 percent year-on-year to 473 megawatts.

Energy free residences are not only practical but they are the dwellings of the future. Let's hope that home builders start thinking zero net energy as they design upcoming housing subdivisions.
This article explains: some background to our bungalow design, why we had the original mechanical ventilation and heat recovery system installed; why we chose the latest system and our experience with both systems.
Many people mistakenly buy larger air conditioning units than they need because they believe that a larger unit will both operate and cool their house more efficiently. In truth, a larger unit could be less efficient.
One university's quest to revolutionize the built environment.
BeyWatch is a 30-month research project supported by the European Commission (DG Information Society and Media) aiming at ICT tools for environmental management and energy efficiency. BeyWatch develops an energy-aware and user-centric solution, able to provide intelligent energy monitoring/control and power demand balancing at home/building & neighbourhood level.
How many of us defrost frozen meat with running water instead of letting it thaw in the fridge? How many times do you use the hose to sweep off the driveway when a broom can be just as effective?
The only severe downsides of having greenroofs in a desert climate are cost of installing it, and then the water use for irrigation. But as we'll see, the water needed for irrigation is more than covered by available greywater.
All in all, I am impressed with some of the strides that have been taken in rebuilding the coast with green in mind. While by no means is it an end to the challenges on being more efficient and using more alternative energy, it is a a start.
I started my sustainability project with a theme, "Grow What You Can Eat." It was my hope to use natural free resources water and solar energy to live a more sustainable lifestyle. Though the progress may be slow, I am proud to see the changes that my neighbors and other communities have made in realizing the value of this global issue to be solved by each one of us. As a specialist in the education and implementation of water conservation and rain water harvesting, we all should take small steps with end goal of someday achieving total sustainability.
