During the real estate boom, new home construction became a game of ever increasing square-footage. That had a certain logic to it: if you saw your house as an investment to make you rich, bigger could only mean better: as a contractor a bigger home meant more profit.
Now that the economy has changed and people are realizing the reality of flat home prices, houses are getting smaller - and more efficient (for many reasons). Ninety percent of homebuyers are very concerned about energy prices and most big homes are energy hogs. Architects and homebuilders are hopefully now considering to how families actually spend time and use space.
What does the new American home look like? As soon as you step through the front door the grand entryway usually a two-story foyer (it is very expensive to heat and cool empty space) is giving way to a more modest entrance. Stairs are less about architectural flash and more about getting upstairs (if there is even an upstairs). The new buyer wants the room not the empty space.
The shift in buyers is driving the changing home. People in their 20s-30s want rather simple starters that put minimal space to efficient use. And those who have retired and are no longer interested in high energy and high maintenance homes may want the same thing with. for them we are also seeing high function efficient homes that are also high style. The big-box house is no longer the market favorite.
The inside of the house is also changing. The great room that first caught on in the early 1990s is undergoing a revival - a large, undelineated family room-breakfast nook-kitchen combination meshes well with attitudes of casualness and flexibility. The formal living room and dining room have become dinosaurs.
Meanwhile, outdoor living space is growing in popularity. There is an increased demand for things like outdoor kitchens and fireplaces so there are no longer the strict divides between how people live inside and outside.
The housing that has been built doesn't fit the market well any longer Which is part of the reason that, even with so many existing homes sitting unsold, we keep building.
Now that "green has become such a buzzword we are continually being flooded with products, building materials, buildings, and services advertising their green product.
This now requires the buyer to do due diligence in order to insure that the product or service is really as advertised.
Fortunately there are now groups (usually non-profit) who offer strict third party certifications Looking for seals such as these can help insure your product is truly green. For consumer products the best option would be Good Housekeeping Green. It still can be a challenge to find the right builder since LEED and NAHB do not have builders listed on their site.
ENERGYSTAR This blue and white symbol can be found on products, applainces and now homes that have qualified as more energy efficient. To earn the ENERGY STAR, products must meet strict energy criteria that have been set in place by the U.S. Environmental Protection Agency or the U.S. Department of Energy. These products include refrigerators, dish washers and light bulbs. You will see many builders advertising themselves as EnergyStar, to check this go to the website where you will find a list of all builders who are currently rated as EnergyStar. It is also important to understand that many ES products are only as good as the people who install them
The United States Green Building Council is an internationally recognized green building certification system, providing third-party verification that a building or community was designed and built using strategies aimed at improving performance across all the metrics that matter most: energy savings, water efficiency, CO2 emissions reduction, improved indoor environmental quality, and stewardship of resources and sensitivity to their impacts. There are four levels of certifications certified, silver, gold and platinum. There are only a few of these in lower Delaware (look at the Center for the Inland Bays). Unless you are passionately commited to building a completely sustainable home, this designation carries larger costs.
NAHB's National Green Building Program is the first residential green building rating system to undergo the full consensus process and receive American National Standards Institute approval. The four threshold levels - Bronze, Silver, Gold, and Emerald - allow builders to achieve entry-level green building, or the highest level of sustainable "green" building incorporating energy savings of 60% or more. Single-family & multi-unit homes, residential remodeling projects, and site developments are all covered in the Standard.You will find that many of the fine builders in this area have added NAHB Green to their credentails.
Good Housekeeping Green Seal - This label bares a strong resemblance to its famous counterpart with the distinction of it's color (green). The Green Good Housekeeping Seal will debut later this year, after the Good Housekeeping Research Institute and a consultancy firm complete development of product evaluation criteria. To be eligible for the green seal, a product must meet the criteria for the original seal of approval, as well as meet standards related to product composition, manufacturing and packaging.
GREENGUARD Indoor Air Quality These planet-toting logos can be found on building materials that are manufactured to help "improve indoor air." The GREENGUARD Environmental Institute (GEI) is a nonprofit organization that oversees the certification programs for building materials and indoor products. These logos let a consumer know that the products are regularly tested to meet chemical and particle emissions acceptable under IAQ pollutant guidelines and standards.
Scientific Certification Systems - This independent company gives certification of environmental, sustainability, food quality and food purity claims for products across the globe. Their extensive network covers consumer goods such as produce, fisheries, forestry, eco-products and floral.
ARE YOU BAFFLED YET?
If this seems a little baffling.... that's because it is and it has taken me quite a while to get a handle on it. As part of the services Green Realtors offer their clients is the ability to help them decide what kind of home they want and recommend those professionals who would be the best person to help them.
The myth that an energy efficient home or green home is only for those who can spend a lot of money is really...just a myth
Nike has taken the top score for the annual Climate Counts scorecard for the second year in a row, but there are some companies hot on Nike's heels and others that made large leaps in the past year.
Climate Counts' third annual scorecard covers 90 consumer companies on their efforts to measure and reduce their climate impact, support or oppose climate legislation and disclose their climate-related actions.
The non-profit points out that many of the corporations have strengthened their voluntary actions throughout the recent economic downturn and notes that high scores in the electronics and consumer shipping sectors came about due to competition among companies to have lower climate impacts.
For the first time, all 12 companies in the electronics sector of the scorecard and all four in the consumer shipping sector received scores of more than 50 points, out of a possible 100.
“Competition - the most fundamental tenet of a thriving global marketplace - will define the future of corporate climate action and sustainability,” said Climate Counts Executive Director Wood Turner in a statement. “Our scores show that companies are motivated to act when they may not measure up to other companies on their response to issues that matter to people.”
Corporations are rated as "striding" if they receive 50 or more points, "starting" if they receive 13-49 points and "struck" if they receive 12 or fewer points. In the latest scorecard, 45 are striding, 31 are starting and 14 are stuck. Only 17 companies saw their scores stay the same or go down compared to last year's scores.
The top 10 scores were taken by:
Nike, 83 points Stonyfield Farm, 81 Unilever, 80 HP, 79 IBM, 76 General Electric, 74 Canon and Toshiba, tied at 71 UPS, 69 Deutsch Post/DHL WorldNet, L'Oreal and News Corp., tied at 68 Motorola, HSBC and CitiGroup, tied at 67
Some companies that made large leaps compared to last year include Ebay (48-point increase), US Airways (43-point increase), Apple (41-point increase) and Levis Strauss (36-point increase).
The bottom 10 scores went to:
SkyWest Air, 0 Regions, 1 Wendy's Arby's Group and SunTrust, tied at 2 Viacom and PNC Financial Services, tied at 3 AirTran, 5 VF Corporation, 6 Liz Claiborne and ExpressJet, tied at 7 Burger King, 10 Capital One and Carlson, tied at 12 Hyatt, 13
The scores are based on 22 criteria that look at four areas: measuring climate impact, reduction of impact, engagement on public policy related to climate change, and openness and transparency with consumers on corporate climate activities. The scorecard includes corporations in the apparel, internet/software, media, electronics, beverages/beer, food services, household products, banks, airlines, food product, hotels and consumer shipping sectors.
Geothermal Savings Negate Upfront Costs Posted By: Jamie on 11/16/2009
It's too soon to know how much he'll save on his monthly energy bills, but Dave Maas has been pleased so far with his home's new geothermal heating and cooling system.
"It seems to have heated the house on cold days and seems be cooling our house much better than our old system on warm days," said Maas, New Palestine.
November 14, 2009, by Angie Hicks Published by Indianapolis Star Photo: Dave Maas says the only drawback to installing a geothermal system was having his backyard torn up. Credit: Indianapolis Star
Geothermal units tap into energy that comes from heat sources deep in the earth, eliminating the need for fuel to heat or cool a home. The units use a loop system in which piping is buried underground and brings heat from the earth into the home during the winter. In the summer, it does the reverse and draws heat from the home back into the earth.
"The only downside I've experienced with the system had to do with the fact they had to tear up my backyard in order to put the loop in," Maas said.
Geothermal units actually produce more energy than it takes to operate them. It's clean energy with few carbon emissions, and delivers up to $5 of energy for every $1 used. That translates into an efficiency rating of 500 percent. By comparison, the best gas furnaces are about 95 percent efficient.
Maas began researching heating, ventilation and air-conditioning systems after deciding it was time to replace his 23-year-old furnace and air conditioner.
Geothermal systems cost more than traditional systems -- Maas estimates he spent about $15,000 for his. But homeowners can recoup 30 percent of a unit's cost through an energy federal tax credit. Lower energy bills also mean year-round savings.
"It made the number come out a lot closer between a traditional heat pump furnace system and a geothermal system," Maas said of the savings. "I thought for the long run, the geothermal made more sense for me, so I went ahead and paid the higher price -- with the understanding that next year I'll get the tax credit applied to my tax return."
The U.S. Department of Energy says 43 percent of the typical homeowner's energy bill goes toward heating and cooling. Geothermal heat pumps are highly efficient and cost little to operate.
The U.S. Environmental Protection Agency estimates homeowners with geothermal systems can save 30 percent to 70 percent on heating and 20 percent to 50 percent on cooling costs over conventional systems.
Not every heating and cooling company installs geothermal units, so it's important for homeowners to do their research before making a purchase. Loop installers are certified by the International Ground Source Heat Pump Association.
Industry experts estimate that geothermal units, which also heat water in homes, will average twice the lifespan of traditional heating and cooling units.
The units are self-contained, so there is no separate air-conditioner, and they operate more quietly than conventional units.
"It's considered green technology," said Rusty Burch, owner of Plainfield-based Total Comfort Solutions. "It's really a super quiet operation. You can hardly hear it running."
One million energy-efficient homes qualifying for the Energy Star rating have been built in the U.S. since the program was launched in 1995, the Environmental Protection Agency said.
This year, Energy Star households will save $270 million -- or an average of $200 to $400 each -- on utility bills. The homes, which tend to be at least 15% more energy efficient than standard homes, will also avoid more than 4 billion pounds of greenhouse gas emissions.
Nearly 17% of all single-family homes built in 2008 qualified for Energy Star, compared with 12% the year before. Across the country, more than 6,500 are building to the program’s standards.
The EPA also released a list of the top 20 cities for Energy Star homes, lead by the Houston area, with 144,420 total homes built. Following were Dallas, Las Vegas and Phoenix regions, with the Los Angeles sprawl rounding out the top five with 53,673 homes.
We’re just about ready to insulate our basement game room and have been exploring a number of options for achieving maximum efficiency. I thought our research might help a few of you out there who are looking to tackle this job on your own. For those of you who haven’t been following along with the project, here’s a brief summary of where we are today, with several pictures of the unfinished wall space. (If you want to see the layout, follow that link to see the finished basement layout).
One Project Closer Basement Wall Construction & 2×4 Wall Studs
The basement walls are constructed of stacked cinder block. The front half of the house is completely underground, while the back of the house is mostly at ground level, with a small area about 2-3 feet underground. The house has decent grading that keeps water away from the foundation, but moisture was still a problem in a few sections.
We used a combination of Super Thoroseal and SunnyDry foundation waterproofers to seal out the remaining moisture, and regraded the gardens in the front of the house. Together, the results have yielded good results, we haven’t had any moisture problems since.
While we’ve taken precaution to ensure the wall seal is tight and that no water is leaking, we still want an insulation product that is mold resistant, since I have a lingering fear that moisture could seep back in at some point in the future (say, due to settling of the foundation and a break in the seal).
We framed the basement walls using traditional 2×4 stud walls fastened to a pressure treated 2×4 bottom board. We briefly considered metal stud framing, but still like the solidity and rigidity of wood, so we stuck with what we knew. The walls are not fastened to the cinder block (as that would penetrate the water tight seal). Instead, the walls are fastened to the joists above, and we used powder charge nailer to fasten the bottom board in place.
We left about a 1 inch gap between the cinder block and the stud wall to provide extra space for wall insulation, figuring we’d need that to get maximum efficiency.
R-13 Fiberglass Basement Wall Insulation
The first option up for consideration is fiberglass batting: the traditional R13 pink fiberglass available at the big box store.
Fiberglass Pros: Fiberglass is good because it’s relatively cheap; it doesn’t require any special installation tools; it can be brought to the house using a standard pickup truck; and, it can be installed by hand in a single day.
Fiberglass Cons: The drawback of fiberglass is that it doesn’t provide great R-value (about R3 / inch), and it can be susceptible to mold with unfavorable moisture conditions. Fiberglass is considered a mold resistant product; however we’ve seen several instances of molding fiberglass batting, including the fiberglass we removed from this basement when we started working it. Fiberglass also doesn’t fill every nook and cranny of the walls, leaving gaps for air to circulate, which ultimately contributes to energy loss. These air gaps are not considered in the reported R value of the insulation, making the effective R value much lower.
We ultimately decided against fiberglass because we’ve had a pretty significant draft in the basement and even with fiberglass installed, this draft will still be leaching energy from the room.
Wet Cellulose Wall Insulation
The second option up for consideration is wet cellulose insulation. We looked at products like NuWool Wall Seal Insulation, a sprayed-in wet cellulose insulation.
Wet Cellulose Pros: Wet cellulose is a sticky cellulose product sprayed into the stud walls. The R-value is slightly higher than fiberglass at about R4 / inch. The main advantage of wet cellulose over fiberglass is it’s ability to fill the cracks and voids that fiberglass batting leaves open, providing a much tighter building envelope. It has a number of other advantages including being highly fire resistant and eco-friendly. It Provides a slightly more cost-effective solution than spray foam products, but does not offer as tight a seal. Wet Cellulose Cons: Higher cost than fiberglass (but worth it considering the added insulation value and energy savings); requires special installation tools and entails a somewhat “messy” installation. Would be best performed by a contractor, although DIY kits are available and we considered these. Cellulose is mold resistant but still susceptible to mold in the least ideal environments.
We decided against wet cellulose insulation because spray foam offered a better alternative. If you’re looking for cellulose installation instructions, Todd provides them at that link.
Spray Foam Insulation: Open Cell Insulation
The third and fourth options up for consideration are spray foam insulation products. I’m starting with open cell insulation because it’s less expensive and not the option we ultimately chose. That said, open cell insulation is a good product that can be very cost efficient for many installations.
Open cell spray foam insulation is a chemical product that is sprayed onto the wall and then expands to fill the space. The term Open Cell refers to the cell structure of the resulting foam, which cures to a sponge-like material with millions of tiny open bubbles. The consistency is similar to angel food cake. The chemicals are mixed on site using a special compressor and gun system. The compressor may heat the foam to a required temperature. When sprayed on the walls, the foam sticks and expands in place.
Open Cell Foam Pros: Open cell foam is sprayed in place and expands to fill the space. It creates a better seal that spray cellulose and provides a comparable R-value in most installations (about R4, slightly higher than fiberglass). Spray foam is nice because it can be sprayed blindly into a cavity and will fill the space of that cavity.
Open cell foam expands to 100 times its spray-on size, making it extremely good for filling voids and relatively cost efficient. It is also nice because it stays somewhat flexible, which is good for ensuring flat drywall installation. Open Cell Foam Cons: Open cell foam does not provide as tight a seal as closed sell foam because the bubbles are broken and it is easier for air to flow between the cells. Unlike closed cell foam products, open-cell foam products are generally filled with air. Closed cell products can be filled with a chemical that is much less efficient at transferring heat that air, leading to greater energy efficiency. Also, closed cell products can nearly double the insulation performance of open cell products.
Closed cell spray foam is very similar to its open cell counterpart, with the exception that the bubbles in closed cell foam are ‘closed’ and so do not permit any air flow. You can think of closed cell foam as a very tight honeycomb of closed cells that are waterproof and air tight.
Closed cell foam can come in a range of different cured hardnesses, all the way up to foam that can support human weight. Closed cell spray foams can also be designed so that they cure with bubbles filled with non-air chemicals that improve energy efficiency. Closed Cell Foam Pros: Closed cell foams offer very high R-values (R7.5 per inch!). Closed cell foam completes the building envelope and tightly seals gaps to prevent air flow. Closed cell foam is highly mold resistant and also provides a vapor barrier for the installation. Closed Cell Foam Cons: Best performed by a professional installer, although DIY kits do exist. Significantly higher price than fiberglass, but offers a superior seal. Recommended Method
While closed cell spray foam is slightly more expensive than other methods, it offers high R-value with the best mold resistance. Given that we’ve invested thousands of dollars in radiant floor heating, we believe that the higher cost is justified and would recommend this method.

The bathroom is a room that often has very poor indoor air quality. In fact, it is usually one of the most polluted rooms in the home. One reason for this is because it frequently a small, closed room without adequate ventilation. But the biggest cause for the poor air quality is the types of products commonly used there.
Here are the top three highest priority fixes for cleaning the air in your bathroom:
1. If you receive municipal water, install water filters for both the shower head and the tub faucet to eliminate chlorine. If your water comes from a well, make sure your water is filtered with a whole-house filter, or at the tap.
2. Switch all personal care products to ones with natural scents, not synthetic fragrance. Look on labels for essential oils and avoid those with the word “fragrance.”
3. Substitute green cleaning products for any product you use in the bathroom (cleaning, pesticide, etc.) with a signal word on its label stronger than a “caution.” The “green” products available on the market in health food stores and health section of the supermarket can cover all your cleaning needs in the bathroom. --By Annie B.

Book Review: Sustainable Energy -– Without the Hot Air, by David JC MacKay
I recently finished reading a book I strongly recommend to anyone interested in sustainable development and energy. It is packed with figures and findings that I believe will easily start discussions among CleanTechies.
The author, David JC MacKay, is Professor in the Department of Physics at Cambridge University and was recently appointed Chief Scientific Advisor to the UK Department of Energy and Climate Change responsible for the Low Carbon Transition Plan.
One of the main findings of this book is that electrifying our cars and installing heat pumps in our buildings would enable us to cut significantly both our greenhouse gas emissions and fossil fuel consumption. Both solutions are much more efficient than the current traditional ones and could benefit from massive electrification to answer all our energy needs.
Below is a selection of the book’s key findings:
Sustainable Electricity: MacKay believes that the UK and Europe in general can’t count solely on renewables. He shows that wind, biofuels, hydro, solar PV and other energy sources don’t add up enough energy to answer our current needs and will do so to an even lesser extent in the future, once we have a strong electrified transport sector.
So we need a plan that provides additional resources, for example concentrated solar (like the Desertec project), or nuclear, or a combination of both. Clean coal may also add up enough electricity if proven viable.
North American Energy Consumption: The author notes that the continent should first and foremost decrease energy consumption from 250 kWh per person per day to the current European or Japanese levels of 125 kWh. This could enable the continent to rely solely on renewables with the installation of concentrated solar in its deserts.
European Energy Consumption: With Europeans consuming the equivalent of 125 kWh per day per person, we see a breakdown of transport accounting for 40 kWh per day, and heating for another 40 kWh. Delivered electricity amounts to 18 kWh but due to the inefficiencies of the system, this comes from 45 kWh of energy. With improved efficiency, we could go from the current 125 to around 80 kWh, a figure similar to that of Hong Kong. (This simplification for the sake of the argument doesn’t take into certain factors that are are tackled in detail in the book.)
Future Scenarios: In chapter 27, the author gives five examples for plans that add up enough electricity. The baseline plan is as follow: Clean coal 16 kWh per day per person, nuclear 16, tide and wave 5.7, hydro 0.1, waste 1.1, pumped heat 12, wood 5, solar thermal 1, biofuels 2, solar PV 3 and wind 8. The four other plans give more or less importance to each of these energy sources. In one plan, nuclear accounts for 44 kWh when in another plan, wind energy accounts for 32 kWh.
Transportation: Today, electric cars need as little as 15 kWh for 100 kilometers while models running on oil need 70 to 90 kWh. Hence, electric cars are already five times more efficient than current conventional models. (Side note: SUVs – also called spaceships by the author – need around 120 kWh…) High speed rail and other sustainable alternatives also have to be pushed forward. A full high speed train only consumes as little as 3 kWh per passenger, and biking consumes even less: 1 kWh.
Housing and buildings: The author is an advocate of both retrofitting and reducing the winter thermostat from 20°C to 17°C, which alone brings savings of 30% (page 292). By combining both solutions, David MacKay halved his heating bills. With a coefficient of performance (COP) of 4 to 5, heat pumps retrieve the heat contained in the outside air or soil and distribute it indoors. Another advantage of this solution is that it can bring air conditioning during hotter days.
The book is available for free on the official website. You can download it in one document or read it per chapter. The paper version can be bought for around $32 / €22. Published this year, it is up to date and explains simply but most effectively (and with a good sense of humor) how we can create a low carbon energy economy.
Grade : 20/20. A must read.
Readability: Maximum as it brings a lot of data.

Senators Introduce Solar Manufacturing Jobs Creation Act
Sen. Debbie Stabenow, D-Mich., Sen. Robert Menendez, D-N.J. and Sen. Michael Bennet, D-Colo., have introduced the Solar Manufacturing Jobs Creation Act. The legislation will provide a tax credit to support solar manufacturing in the U.S.
Currently, a 30% solar investment tax credit (SITC) exists for the investment in or installation of solar power technology, Stabenow's office notes. Under the Solar Manufacturing Jobs Creation Act, equipment and facilities used to manufacture solar power technology would be added to the eligible property list for the SITC.
Rep. Dave Camp, R-Mich., plans to introduce the companion legislation in the House later this month, Stabenow’s office says.
"Not long ago, the U.S. was the leading global manufacturer of photovoltaic solar cells," said Solar Energy Industries Association President Rhone Resch in a statement of support for the bill. "But we've fallen behind Europe and Asia because we didn’t have the right policies in place.
"By extending and expanding the solar manufacturing tax credit, we’ll have the support necessary to compete with other countries and continue creating jobs in the solar industry," Resch continued.

When Congress passed the financial bailout bill late last year, it included a range of federal tax credits and cash gifts for businesses -- but also a suite of new and renewed tax credits for individuals who want to make energy efficiency and renewable energy improvements to their home or cars. When President Obama signed the economic stimulus bill in February, the federal government expanded and extended some of those credits.
So what's in it for homeowners and other regular taxpayers? There are several important provisions anyone can take advantage of (changes made by the economic stimulus bill are in bold). This list includes:
$1,500 Home Tax Credits for Energy Efficiency
You can claim a home tax credit for energy efficiency improvements made in 2009 (but not for improvements made in 2008) if you installed new insulation, energy-efficient windows or an energy-efficient furnace, boiler or air conditioner.
A tax credit of up to $500 that expired in 2007 has been renewed for 2009 by the bailout bill, and expanded to $1,500 by the economic stimulus bill. It covers up to 30% (expanded from 10% by the economic stimulus bill) of the cost of a range of projects that meet certain specifications. Do $5,000 worth of qualifying work, and you not only get a $1,500 rebate, but also savings on energy bills for years to come.
The economic stimulus bill also stripped out most caps on individual home improvements, which had applied to windows, heating equipment and other energy efficiency improvements.
Note that the tax credit applies only to equipment, not labor.
Find more information about these home energy efficiency tax credits at the Alliance to Save Energy or Energy Star or Department of Energy Websites. Note that much of this information reflects the tax incentives in place in 2006 and 2007; for the most part, the 2009 tax credits are identical, but check updated criteria for which products qualify, for instance.
30% On Home Energy Tax Credits for Geothermal, Solar, Wind Turbines or Fuel Cells
The economic stimulus bill removed the $2,000 cap that had applied to geothermal heat pumps, solar panels and other home renewable energy technology. The 30% tax rebate on qualified solar energy systems remains in place on geothermal heat pumps, small wind turbines, and fuel cell systems.
Ground-source heat pumps are installed underground and use the constant 50-degree subsurface temperature to cool air or water in the summer, and heat it in the winter — both of which reduce the cost of heating or cooling year round.
In addition, the solar energy tax credit, which had been set to expire, is now good through 2016. $500 Home Energy Tax Credits for Fuel Cells or Microturbines
The tax incentive that had covered 30% of the cost of fuel cell or microturbine systems in homes, which lapsed in 2008, has been restored for 2009 and through 2016. It covers up to $500 per 0.5 kw of capacity.
$7,500 Energy Tax Credits for Plug-in Hybrid Cars
The first 200,000 buyers of plug-in hybrid vehicles from each manufacturer now qualify for a $7,500 tax rebate.
A similar tax credit for hybrid vehicles had been capped at $3,500 before the bailout bill.
$2,500 for Plug-in Electric Motorcycles or Low-Speed or Three-Wheeled Vehicles
The economic stimulus bill established a 10% tax credit through 2011 with a cap of $2,500 for new electric plug-in motorcycles, low-speed and three-wheeled vehicles. There's also a 10% tax rebate and a $4,000 cap for converting an existing vehicle to a plug-in.
$50,000 for Installing a Clean Fuel Refueling System
While few homeowners may be ready to take advantage, those who want to install a clean fuel refueling system, like a natural gas refueler or a recharging system for a plug-in electric vehicle, can now qualify for up to $50,000 -- up from $30,000 -- if the system is installed in 2009 or 2010, thanks to the stimulus bill. Go with hydrogen and the credit increases to $200,000, and you have until 2014 to take advantage of it.
Wildcard: State Energy Tax Credits
Keep your eyes out for new incentives from your state, since the bill also authorizes an $800 million government bond program that encourages states to create incentives for new and existing energy conservation and related programs. Some of that money is likely to be used toward state tax breaks and other incentives that will vary by location. Among the incentives to watch for is up to $6,500 per qualifying home in the Weatherization Assistance Program. The Department of Energy's Office of Renewable Energy and Energy Efficiency, which provides grants to states and local governments that trickle down to individuals, had its budget increased nearly 10-fold. Check out the Database of State Incentives for Renewable Energy & Efficiency for more federal, state and local grants, rebates and incentives.
With the holidays fast approaching and recent health scares relating to childrens' toys, ensure your little ones receive safe, happy, and dare I say educational, toys. Check out the Safe Green Toy Gift Ideas list (courtesy of TheDailyGreen.com) for cool finds like this Eco-House complete with recycling bins, solar panels, wind turbine and rain barrels (and it's made from sustainable materials).
Enjoy a good vintage. In the mood for a festive and romantic drink? Try sipping a glass of organic champagne. Nothing will put you in a romantic mood faster than sharing a taste of champagne together. The demand for organic champagne is growing quickly, so there are several good choices available. Try NV Pascal Doquet Premier Cru Rosé with its hints of rose and strawberry. Or NV Albert Mann Crémant d’Alsace which has apple, citrus and floral notes.
Take a walk. Take advantage of the cooler temps to walk hand-in-hand with your sweetie through the tree-lined streets of your neighborhood or park. Walk to the store to pick up those last minute items for Thanksgiving. Stroll to the mailbox to drop off your holiday greeting cards or simply window shop together. In the middle of the hectic holiday season, walking together gives you time to reconnect and share your day. Now that’s romantic.
Light a fire. Turn off the furnace and heat up the old fashioned way... with a fire! What could be more romantic than a cozy blanket stretched out in front of a roaring fire. Take advantage of the romantic glow and snuggle up. If you’re hungry, add some old fashioned popcorn. Using your fireplace will save on energy consumption and when the fire has burned out, you can spread the ash in your garden to help feed your plants over the winter.
Don’t curse the darkness, light a candle. Why not spend an evening gazing into each other’s eyes by candlelight? Have dinner, play a game or just talk to each other. No matter what activity you choose, everyone looks good by candlelight. Candlelight promotes conversation and intimacy. For a super-sexy choice, try 100% soy Candles By Claire. Not only do they melt into massage oil as they burn, but they are also 100% Vegan (not petroleum based) and produce 99% less soot than paraffin candles.
Dine Alfresco. Who says you can’t enjoy a fall picnic. Put on your warmest sweater and carry your meal to the park or the lake. Take in the crisp air and the beauty of fallen leaves while you cuddle your significant other. Picnics are all about anticipation, so enjoy it! You really don’t have to spend a lot of time in the kitchen preparing for a romantic picnic. Grab a loaf of crusty bread and bottle of organic wine. (Find 5 good selections at The Daily Green.) Throw in a few other traditional aphrodisiacs like almonds and figs, if you like. Maybe add a good organic goat cheese with italian herbs from Coon Ridge Farms. And don’t forget something sweet. Perhaps some eco-friendly chocolates from Fat Turkey Chocolate in Austin, Texas. Gobble, gobble!
Sleep under the stars. Grab your sleeping bag and head for the great outdoors. Time to enjoy an unobstructed view of the heavens, and get romantic. I mean, what could be sexier than two people huddled together in one sleeping bag?
Take A Bath...Together. What better way to conserve water and warm up on a cold evening. You’ll be doing your part to help save the environment, and having some fun, too. Spice things up with a bath sachet. Take a small square of linen or cheese cloth. Add a cinnamon stick, a few whole cloves and some orange peels. Tie with a piece of cotton twine and toss in your warm bath water. Let steep while you bathe. Or add a few drop of Nutmeg Essential Oil from Essential Aura Aromatherapy. Volunteer Together. Doing good feels so good, doesn’t it? What could be sexier than doing it together? (Oops, almost made it through the whole article without a pun.) But seriously, all that hard work. All that helping and relying on each other to see a project though. All that feeling good about doing good. Get it? So do some good, together. Volunteer at a local soup kitchen. Delivery gift baskets from your church or work at a pet adoption. But do it together. It’s the romantic thing to do. Now get busy!
By now we’ve all heard that everything from hair serum to sunscreen can be teeming with troublesome toxins and crazy chemicals, and many concerned consumers already steer clear of products made with parabens, phthalates, and synthetic scents and colors. But there are hundreds of lesser-known ingredients hidden in many favorite products–some with the potential to wreak havoc on the environment and others that have been linked to breast cancer. Without a universal and enforceable natural or organic standard to regulate the beauty industry, even companies claiming to be natural often produce products laced with not-so-clean stuff.
For their 2nd Annual Beauty with a Conscience Awards, Natural Solutions magazine put its stamp of approval on 101 of the purest and best personal care products using guidelines developed in collaboration with Whole Foods Market, here is their list of the toxic ingredients that you don’t want in your products.
1. Synthetic fragrances often contain phthalates (pronounced THAY-lates), synthetic chemicals commonly used to stabilize fragrances and make plastic more pliable. These endocrine disrupters mimic hormones and may alter genital development. Avoid products that list fragrance as an ingredient unless the label states that it’s derived from essentials oils, or look for a phthalate-free label on the packaging.
2. Parabens, ubiquitous in skincare, preserve other ingredients and extend a product’s shelf life–but these antimicrobial chemicals also have hormone-disrupting effects.
3. Ureas, formally known as diazolidinyl urea, imidazolidinyl urea, or DMDM hydantoin and sodium hydroxymethyl-glycinate, are preservatives that have the potential to release formaldehyde in very small amounts and are a primary cause of contact dermatitis.
4. 1,4-dioxane, a chemical carcinogen, is created when ingredients are processed with petroleum-derived ethylene oxide. Common ethoxylated compounds include sodium laureth sulfate and polyethylene glycol (often listed as PEG). To avoid it, skip any product with the following ingredients: myreth, oleth, laureth, ceteareth (or any other -eth), PEG, polyethylene, polyethylene glycol, polyoxyethylene, or oxynol.
5. Petrochemicals are derived from crude oil. Petroleum-based ingredients such as petrolatum, mineral oil, and paraffin (derived from nonrenewable sources) form a barrier when applied to the skin that does not allow it to breathe and can clog pores.
6. MEA/DEA/TEA are “amines” (ammonia compounds) and can form harmful nitrosamines when they come in contact with nitrates. Used as foaming agents, synthetic stabilizers, and to adjust the pH of cosmetics, they can cause allergic reactions, eye irritation, and dryness of the hair and skin.
7. Sulfates, such as sodium lauryl and sodium laureth, are harsh detergents that give cleansers, soaps, and shampoos their latherability. Often derived from petroleum, sulfates can also come from coconut and other vegetable oils that can be contaminated with pesticides. Sulfates can cause eye irritation and skin rashes.
8. Chemical sunscreens, such as oxybenzone and octyl methoxycinnamate, have been shown to disrupt endocrine activity. Titanium dioxide and zinc oxide are safer alternatives. 9. Quats, such as benzalkonium chloride, steardimonium chloride, cetrimonium bromide, and cetrimonium chloride, give a positive charge to conditioners in order to prevent static. They are necessary for conditioners, but we have allowed only the mildest quats in our Beauty With a Conscience standard: guar hydroxypropyltrimonium chloride, hydroxypropyltrimonium oligosaccharide, and SugaQuats. 10. Antibacterial compounds, such as triclosan and chlorphenesin, do not break down in the environment and may contribute to bacterial resistance.
11. Synthetic polymers, such as sodium polyacrylate and carbomer, come from petroleum and give viscosity to skincare products. They are highly processed and their manufacture creates toxic by-products.
12. Synthetic colors are made from coal tar. They contain heavy metal salts that may deposit toxins onto the skin, causing skin sensitivity and irritation. Animal studies have shown almost all of them to be carcinogenic. They will be labeled as FD&C or D&C, followed by a color and a number. 13. Chelators, such as disodium EDTA and tetrasodium EDTA, are used in personal care products to remove impurities from low-quality raw materials. They do not readily biode- grade in the environment. 14. Nanos are a new technology with inconclusive but potentially hazardous study results. Research suggests that when tiny nano particles penetrate the skin, they may cause cell damage.
15. Animal testing: A grim history of cruelty to animals lies behind many cosmetic ingredients. But scientists are developing new technologies to test cosmetics before a European Union ban on animal testing begins in March 2009.

Nov. 7 recycling event in Wilmington nets 8.5 tons of scrap tires; State’s third event brings total to nearly 5,000 tires recycled
WILMINGTON, Del. - Saturday’s Scrap Tire Drop-off event at Frawley Stadium netted 8.5 tons of scrap tires – more than 650 old passenger vehicle tires that could have ended up in an unsightly, scrap tire pile or left to decompose in a Delaware landfill. The event, the third held in the past year, provided Delaware residents with the opportunity to recycle scrap tires free of charge and help reduce the environmental and health hazards of scrap tires in our communities.
“Our three drop-off events have collected nearly 60 tons or 4,800 scrap tires,” said administrative manager Laurene Eheman of DNREC’s Solid and Hazardous Waste Management Branch. “Delaware residents from each county have responded to our recycling program. With the tremendous response we’ve had over the past year, a fourth Scrap Tire Drop-off is planned for next spring in the Seaford-Georgetown area.”
The first Scrap Tire Drop-off day was held Oct. 2008 near Harbeson in Sussex County and netted more than 30 tons of discarded tires. At last April’s event, almost 20 tons of tires were collected at the Delaware State fairgrounds in Harrington.
Delaware’s Scrap Tire Cleanup and Control Program was created to eliminate large, unsightly scrap tire piles that can spawn dangerous fires that produce toxic smoke and oily liquid runoff from melted tires that can pollute groundwater. In addition, tire piles provide ideal breeding grounds for mosquitoes, which can carry the West Nile virus.
The Wilmington Scrap Tire Drop-Off Day was held in conjunction with the Delaware Solid Waste Authority’s Household Hazardous Waste and Electronic Goods Collection Day and the Clean Wilmington Committee’s Shredding Event.
The Delaware Scrap Tire Cleanup and Control Program is funded by a state fee of $2 per tire on the sale of new tires. Enacted Jan. 1, 2007, the fee is diverted to the Scrap Tire Management Fund, a matching fund and program created to clean up existing scrap tire piles statewide.

NRG Energy, Inc. Enters Offshore Wind Business with Acquisition of Bluewater Wind
—Leading offshore wind development company provides NRG with first-mover advantage and currently has the only long-term power purchase agreement in the country executed for an offshore wind park—
PRINCETON, NJ; November 9, 2009—NRG Energy, Inc. (NYSE: NRG) has acquired Bluewater Wind (Bluewater), one of nation’s leading offshore wind development businesses, from Babcock & Brown and Arcadia Windpower. This acquisition combines Bluewater’s strong project pipeline of offshore wind parks in the northeast—one of NRG’s core regions—with NRG’s own successful development, engineering, procurement and construction teams. The transaction was funded with cash on hand, for an undisclosed sum.
“As public policy trends toward ever-increasing renewable portfolio standards at the state and federal levels, each region of the country will seek to comply with projects that tap the best renewable resource from within that region. There is no doubt that offshore wind is the highest potential renewable resource proximate to the population centers along the eastern seaboard of the United States,” said David Crane, President and CEO, NRG Energy, Inc. “Acquiring an experienced offshore developer like Bluewater, with good projects already in the development pipeline, gives NRG first mover advantage in this potentially lucrative market.”
Bluewater brings an experienced development team currently working on more than seven offshore projects in the Northeast, including projects in Delaware and New Jersey in advanced stages of development. Bluewater has a 25-year, 200 megawatt power purchase agreement (PPA) with Delmarva Power & Light Company that has been approved by the Delaware Public Service Commission and other state agencies. In New Jersey, the company is one of three preferred developers awarded a $4 million rebate from the state to build a meteorological tower, which collects wind data, for offshore projects. Bluewater also has proposed several offshore wind projects in other Northeast locations.
Bluewater’s existing development team will become NRG employees, working out of Bluewater’s office in Hoboken, NJ. The company’s President and founder, Peter Mandelstam, will remain President of Bluewater Wind and also serve as head of NRG’s offshore wind development efforts. “Bluewater Wind is excited to continue developing our portfolio of offshore wind parks with a premier energy generation company like NRG,” said Mandelstam. “By joining forces with NRG, Bluewater Wind will enhance its development expertise, as well as access to capital for the development and construction of these projects. NRG’s commitment to increase its portfolio of low and no carbon generation assets, and its membership in the U.S. Climate Action Partnership, is a good fit with Bluewater Wind’s mission to provide clean, stable-priced, renewable energy.”
About NRG NRG Energy, Inc., a Fortune 500 company, owns and operates one of the country’s largest and most diverse power generation portfolios. Headquartered in Princeton, NJ, the Company’s power plants provide more than 24,000 megawatts of generation capacity—enough to supply more than 20 million homes.
