Solar Technology: Solar Shingles
The Dow POWERHOUSE™ Solar Shingle delivers true building-integrated aesthetics by integrating PV functionality into an asphalt roof-shingle form factor. It utilizes high-efficiency, CIGS-based, PV cells manufactured on a flexible substrate. These cells are laminated and subsequently over-molded into the final shingle design using conventional materials and polymer processing methods. Dow's groundbreaking technology integrates low-cost thin-film photovoltaic cells into a roofing shingle design, which represents a multi-functional solar module. The innovative product design reduces installation costs because the conventional roofing shingles and solar generating shingles are installed simultaneously.The DOW™ POWERHOUSE™ Solar Shingle was named one of the "50 Best Inventions of 2009" by Time magazine, and is expected to be available in 2011.

Energy Saving Light Bulbs
We’re greening up our new office by replacing the incandescent light bulbs with Earthmate energy saving bulbs. By using Earthmate bulbs, we will use an average of 75% less electricity, help reduce our dependence on fossil fuels (coal, oil, and natural gas) and reduce greenhouse gas emissions. 
For instance, we replaced our 45 watt overhead bulbs with Earthmate 8-watt Dimmable Reflector Bulbs, which will save us about $61 and last up to 7 times longer than our standard light bulbs. And bonus: they come with a 9-year warranty!

Bringing Smart Energy Home
Bringing Smart Energy Home: Wireless energy dashboards to monitor usage are coming to many U.S. homes starting this year, fueled by the stimulus package, by Katie Fehrenbacher
Thanks to funds from the stimulus package and renewed attention to energy savings, 2009 is the year companies are planning to launch wireless energy dashboards that will sit in your home, monitor energy data from your electricity meter, and let you know if you're being an energy hog. While tech firms have been trying to sell you on the "digital home" for years—complete with wireless networks that can do everything from control your entertainment equipment to operate high-tech security systems and roast a chicken—the new energy-management companies are keeping it simple by using low-cost hardware and open standards to monitor energy data.
This year is particularly important to these mostly young companies, as President Barack Obama has pledged to help utilities install 40 million smart meters, which are basically digital meters that create a two-way connection with the power grid and the utility. Smart meters installed in homes can unleash data about the fluctuating price of electricity throughout the day, enabling consumers that have energy-management tools to shift energy consumption to the time of day when power is cheapest. For utilities, that can mean better management of the power grid, eliminating the need to build out expensive power generating systems. 
In the U.S., 6% have smart meters
A half-dozen companies are launching their first energy dashboards this year and a few others are starting to gain traction with already available online tools. One of the biggest differences between these firms is whether companies will sell directly to the consumer or to utility partners for upcoming smart meter rollouts. Several of the already available options for consumers bypass smart meters and utilities and just help the interested consumer with a standard electricity meter. They're cheap and available online, but they provide less detailed data.
The utility-focused tools use smart meter information to provide deeper energy analysis and can even control smart appliances, enabling utilities to implement demand-response events. But the drawback of such tools is that you'll need a lot of patience and a little luck. To get hooked up via one, you'll need to be in the footprint of a utility that's rolling out smart meters. At this point fewer than 6% of the U.S. population has a smart meter. Monday, May 11, 2009
Residential Solar Energy is HOT!
Solar is the hottest thing in green homes today – and with good reason.According to The Clear Mountain Solar Store, our local solar experts, “all the potential energy of the earth’s known oil, coal and natural gas reserves is equaled by just three weeks of solar energy. It is estimated that the solar energy that reaches the earth on a typical day could supply all the power the earth needs for a year.”
New government incentives and the explosive growth of the solar industry is great news for people building a new home or preparing a green renovation of their existing home.
Photovoltaic systems can be grid-tied or off-grid, are completely safe, reliable, and require minimal maintenance. Better yet, they produce no carbon dioxide or air pollution.
Heating water for our households accounts for about 25% of our total energy costs. A solar hot water system in New Hampshire and Vermont can produce 70% of your hot water needs and can save an average of 60% - 70% in energy costs, paying for itself in 3-5 years.
You can see even more savings by using a solar space heating system in conjunction with a furnace or biomass stove. Clear Mountain Solar explains, “active space heating systems are most affordable when sized to handle about half of a household’s heating needs. Systems designed to offer more are not cost-effective because most of the excess capacity is only used on the coldest winter days, remaining unused the rest of the year.” A solar space heating system can heat one room, a wing, or the whole home. With a return on investment is between 6-8 years, this type of system pays off quickly while you see the benefits immediately!
One of our one story home plans (pictured above) includes both a solar photovoltaic and a solar hot water system. Now is definitely the time to go green with solar energy!

Keeping a Green Home, Remotely

As seen in a recent online issue of The New York Times, soon you will be able to monitor the energy efficiency of your home on your cell phone, wherever you are.
The soon-to-be-released tool, called TREE (Tendril Residential Energy Ecosystem), will allow homeowners to turn appliances, heating, and cooling systems on and off from work, the theatre, or the kids’ soccer practice. Similar to a video game, TREE will integrate with a collection of tools to track energy consumption and broadcast the results to local and distant displays. If your electricity consumption rises above certain levels, a display will start flashing a different color, allowing you to decide which systems you can shut off.
TREE will compare your home’s energy consumption with similar sized homes in your neighborhood, make suggestions on how to reduce your energy, and predict how much lowering the thermostat will lower your bill. How's that for monitoring your carbon footprint?
TREE is expected to be released late this year. To read the full article, click here.
