Energy Efficient Roof Shingles
Home > Your Home > Environmentally Friendly > Articles > Energy Efficient Roof Shingles
The right roof is essential to designing an environmentally friendly and energy-efficient home. If you’ve got typical shingles or hot asphalt on your roof—as many homeowners do—you could be doing better. Below are a few cutting-edge roofing techniques that can cut your energy costs and make your house greener at the same time.
Use recycled shingles. If you want an environmentally friendly roof, the worst thing you can do is install 15-year, non-recycled shingles. These are among the most disposable building materials, are hardly ever recycled, and contain toxic volatile organic chemicals that evaporate under the heat of the sun. This means that just by sitting under the sun and heating up, your home is releasing toxic chemicals into the air. For a greener option, use recycled asphalt shingles that use reclaimed materials, reducing waste. These shingles often have a 50-year lifespan instead of 15, so you won’t have to replace them as often.
Consider metal. Metal roofs are more energy-efficient than shingles. Metal roofing is typically made from aluminum, copper, or steel, and you should ensure that your roofing is lead-free. Metal does not have the kind of heat-absorption qualities shingles have, so it will absorb and radiate less heat into your home. In fact, the right color metal will actively reflect sunlight, keeping your home cooler in hot summer months when the sun is most intense. Metal roofing also stands up to the elements better than shingles typically do—it’s the best for rainwater catchment systems, and snow slides off it easily.
Reflective coatings. To make your shingled roof more energy-efficient, brush a reflective coating on. Uncoated shingled roofs typically absorb around 80% of the sunlight that hits them—heating your home in the summer and driving up your air conditioning bill. A coated roof, however, can reflect about 80% of heat—giving you significant energy savings.
Clay and slate. Two natural materials that make excellent green roofing choices, clay and slate are both energy-efficient, can be disposed of without pollution, and are much less toxic than shingles. Corrugated clay tiles encourage air flow on the surface of the roof, keeping the home cool in the summer. However, hail will shatter it, which is why it’s typically only used in warmer climates. Slate is far more durable—it can last up to 100 years with minimal maintenance. Slate can also be reclaimed and recycled.
Building-integrated photovoltaics (BIPV). This is a roofing system that’s coated with a film that converts sunlight into electricity—a solar-power coating for your roof. This system uses tiles or shingles, and the electric current flows on the edge of the roof. The tiles look like slate, and can be installed by most roofers—an electrician will also be needed to hook the solar-energy system up to your home’s electrical system. The charge it generates isn’t huge—about 1 kilowatt of energy per 100 square feet of tile
Roof turbines. Companies in the Netherlands, Scotland, and Britain are developing small turbines designed to install on roofs and convert wind power into home electricity. The turbines are typically around six feet across, and are usually mounted on the roof or a pole. Roof turbines feed energy into a converter, which transforms it into electricity for home use. They can typically provide enough power to operate lights, a refrigerator, a television, and a computer—providing significant energy savings. However, the amount of energy an individual house sees will depend on how windy its location is

The reason that the title is true is that they charge like 500 percent too much money. I don’t care what Bob Vila says modern 40 $$$ electric heaters are not dangerous and have temperature controls. So why don’t all of these people go to jail? Well, for one, they change their companies’ names every year so they are hard to track down. But there is an argument in the energy efficiency community about what constitutes saving energy, ie. saving money.
Energy efficient space heater
Click here to see our selection of energy efficient space heaters.
Energy efficient space heaters are one of the best ways to cheaply lower your heating bill. According to US Government statistics, the average American spends $1,900 per year for home energy of which nearly half goes to heating and cooling. Space heaters can help lower this bill. Here is the fundamental information you need to make the correct choice for your situation.
By lowering your home thermostat only 5 degrees and employing the use of energy efficient space heaters in frequently used rooms you can lower your heating cost by 10% and eliminate 800 pounds of C02 emissions from the environment. Space heaters will re-warm your space for a fraction of the cost associated with running the central heating. But, to make sure you get the most savings, you have to select the space heater that is right for you and your home. Numerous choices exist including Convection, Micathermic, Ceramic, Radiant, Kerosene, Wood Burning and Gas. With so many choices, we recommend doing your research before making a purchase. No one choice is the correct choice. It will depend on your needs as to what the correct type of space heater is best for you.
Factors to Consider
The first, and obvious factor, is temperature. You will probably want to exclude any that don’t have automatic temperature control as the space you are attempting to heat will either be too hot or too cool and you will constantly have to be monitoring the unit and turning it on or off. This is both uncomfortable and time consuming.
Everyone is well aware of the effect of temperature on comfort. However, the second, and less discussed component of comfort is relative humidity. Relative humidity is the percent of water vapor in the air at a specific humidity. In simple terms, a dry house with 20 percent relative humidity will need a higher temperature to feel as warm as a home with medium humidity of 60 percent. That is because your body is giving up heat by the process of evaporation. The lower the relative humidity the faster your body gives up this heat as the higher moisture of your body evaporates to the atmosphere.
A third factor to consider is wind speed. As the air in your house moves it affects the rate at which your body gives up its heat. This is due to the process of convection which is the attraction of hot air to colder air. A house in which the heat is constantly running feels cooler. This is one of the reasons the old steam style radiant heaters felt so warm. There is little wind speed when compared to a centralized blower. It’s also the reason a fan feels so good in the summertime.
Deceptive and Overpriced
Radiant Space Heater Scams
There are a number of companies selling electric heaters that imply that you will save a great deal of money, some even claim you will cut your costs by 50%. This is extremely misleading. It is sort of like claiming “Save 100% on your heating bills*” where * = “don’t turn it on”. It isn’t a fraud, but is certainly misleading.
Examples are EdenPure, iHeater, so called Amish heaters, the chinese made Heat Surge Roll-n-Glow (their marketing material is the most honest of the bunch).
All portable electric heaters consume electricity and degrade it into heat. All are 100% efficient for one obvious reason. The heat has nowhere else to go except into the room. Anyone that makes a claim otherwise, especially outrageous ones like “10x more efficient than a space heater”, is making a fraudulent claim.
In the images below, cut from an advertisement by Krystal Planet, we see some typical claims — let’s examine them:
a) no combustion, flames or fumes.This is true of all electric appliances,including your coffee maker unless something is terribly wrong.
b)less electricity than a coffee maker. If this is true, then it will give off less heat than your coffee maker. Can you heat your house with a coffee maker? If you can, I’d like to hear about it 🙂
c)Does not dry out the air. Of course not. Electric heaters never dry out the air. How could they? Where would the water go? No matter how you heat up the air in a room, the warmer air can hold more moisture so the relative humidity will go down — unless you want to use a humidifier, vaporizer or keep the kettle boiling on the stove.
d) healthy comfortable infrared heating. Infrared is radiated heat, like you get from a heat lamp or the sun. The product details below imply that the heat source is four 375W heat lamps, but if they are inside the wooden looking box in the picture, then they are not shining on you. They would heat the box and the box in turn would heat the air nearby, which is called convection.
So do they make a natural gas space heater that is safe to use indoors? I have no idea. More tomorrow.

I said all along that the idea that there were huge new oil fields in Alaska was both dangerous and wrong. Dangerous, because if there was oil there, drilling could destroy the ecosphere. Wrong, because like the North Sea, the oil companies always claim there is “oil next door” and then drill dry holes. I have often thought they use this technique to drain capital from smaller investors.
Alaska’s untapped oil reserves estimate lowered by about 90 percent
By the CNN Wire Staff
October 27, 2010 1:35 a.m. EDT
(CNN) — The U.S. Geological Survey says a revised estimate for the amount of conventional, undiscovered oil in the National Petroleum Reserve in Alaska is a fraction of a previous estimate.
The group estimates about 896 million barrels of such oil are in the reserve, about 90 percent less than a 2002 estimate of 10.6 billion barrels.
The new estimate is mainly due to the incorporation of new data from recent exploration drilling revealing gas occurrence rather than oil in much of the area, the geological survey said.
“These new findings underscore the challenge of predicting whether oil or gas will be found in frontier areas,” USGS Director Dr. Marcia McNutt said in a statement. “It is important to re-evaluate the petroleum potential of an area as new data becomes available.”
The organization also estimates 8 trillion cubic feet less gas than a 2002 estimate of 61 trillion cubic feet of undiscovered, conventional, non-associated gas — meaning gas found in discrete accumulations with little to no crude oil in the reservoir.
“Recent activity in the NPRA, including 3-D seismic surveys, federal lease sales administered by the Bureau of Land Management and drilling of more than 30 exploration wells in the area provides geological information that is more indicative of gas than oil,” the geological survey said.
Of course the nutcases still believe this and will until their dieing days.
Huge Alaska Oil Reserves Go Unused
After 30 years, an insider finally acknowledges the United States
has all the oil and gas it needs.
By Marie Gunther
The United States has more oil reserves than Saudi Arabia but this happy though shocking information has been covered up for years.
The wells have been drilled, it’s merely a matter of turning on the faucets to supply America’s needs for 200 years.
These astounding revelations have been confirmed by a 30-year veteran oil exe cutive with leukemia who has decided to speak out.
In 1980, Lindsey Williams wrote a book, The Energy Non-Crisis, based upon his eye witness accounts during the construction of the Trans-Alaska pipeline. As a chaplain assigned to executive status and the advisory board of Atlantic Richfield & Co. (ARCO), he was privy to detailed information.
“All of our energy problems could have been solved in the ’70s with the huge discovery of oil under Gull Island, Prudhoe Bay, Alaska,” Williams said. “There is more pure grade oil there than in all of Sau di Arabia. Gull Island contains as much oil and natural gas as Americans could use in 200 years.”
Oddly though, immediately after this massive discovery, the federal government ordered the rigs to be capped and oil production shut down.
Developing Alaskan oil would make the United States completely independent of oil imports, Williams said in his book.
Why is the government covering up such good news? Why does it want to be dependent on imported oil? Do international financiers who are heavily invested in the oil industry want to keep the supply limited and prices up?
Will the Senate Energy and Natural Resources Committee, chaired by Sen. Frank Murkowski (R-Alaska), investigate what could be a criminal cover-up? Will the appropriate House committees in quire? Or the Justice Department? Since the cover-up has extended through four presidential administrations, only public outrage can force action.
“Everything you hear on the evening news and out of Washington is garbage,” said Jim Lawler, an oil production manager with ARCO. “Eight wells have already been drilled in the areas environmentalists are claiming we must not go in. We have already been in and out. There was no damage done. All we need to do is start production.”

Why in the world would you want to fuel up a 40 year old reactor. Because it is a religious dictatorship and the ayatollahs can order it to be done. It is Allah’s will. Allah definitely has a sense of humor.

Iran begins fueling nuclear reactor
The start of the weeks-long process brings the controversial Bushehr plant another step closer to operation. Iran says the facility will generate 1,000 megawatts of electricity, but Western nations fear it is to be used to produce atomic weapons.

By Borzou Daragahi, Los Angeles TimesOctober 26, 2010|6:53 a.m.
Reporting from Dubai, United Arab Emirates —
Iran began loading nuclear fuel rods into the core of its first nuclear power plant Tuesday, bringing the facility a step closer to producing electricity, Iranian state television reported.
The start of the weeks-long process lends credence to Iranian claims that a high-profile computer virus attack earlier this year did not significantly postpone the launch of the nuclear plant near the southern Iranian city of Bushehr. After years of delay, the plant, built in part by Russian engineers, is scheduled to produce electricity early next year, after all 163 of its fuel rods are moved into the reactor core and undergo tests.
“We hope that nuclear electricity would enter the national grid within the next three months,” said Ali Akbar Salehi, chief of Iran’s Atomic Energy Organization, according to the official Islamic Republic News Agency

Energy Efficient Doors
If you live in a cold climate, chances are that your home is equipped with a variety of defenses against the frigid air outside. A sufficient amount of insulation and storm windows throughout the home are just a few ways to keep the interior of the home warm and cozy. But because a third of heat loss typically occurs through windows and doors, energy efficient doors are among the best defenses against heat loss.
Making Your Current Doors Energy Efficient
Energy efficient doors are insulated and sealed tightly to prevent cold from entering and warm air from leaking out. Regular doors can also become energy efficient doors by adding a few simple weatherproofing accessories, including bottom sweeps, typically made from vinyl, and magnetic weatherstripping.
Energy Efficient Material of Choice: Wood
Energy efficient doors are made from a variety of materials, but wood is considered an excellent insulator. According to professionals, wood is 2,000 times more efficient as an insulator than aluminum, 415 times more efficient than steel, and 16 times more efficient then concrete. For additional energy efficiency, storm doors may be added as well. Storm doors work by trapping air between the main door and the storm door.
High-Quality Materials for Energy Efficient Doors
A good energy efficient door will have high quality hardware. It will also have the best weatherstripping, which offers the best seal. When choosing a door made of materials other than wood, make sure it has a finish that won’t rust. If you are purchasing weatherstripping or replacing your existing hardware, choose the highest quality products you can find. High quality products will not only provide the best seal, but they will also last much longer than lower quality products.
Energy Efficient Doors and Savings
Energy efficient doors provide a wide variety of benefits. Because they keep warm air in and cold air out, you will use less artificial heat; the same is true for the warm summer months. Instead of running the air conditioning all day, you will use it less as more cold air will stay inside.

OK so which is it, are we running out of stuff or not? Is 6 Billion people too many or not? Have we cut down way too may trees or not? I believe these answers are knowable. Are the Ocean’s fished out or not? Is Global Warming happening? The issue seems to be Price. If Global Warming were happening then carbon would be expensive. But what if price isn’t the issue when capitalists and nations treat resources as if they were “free”.

Blog item: Recycling? What A Waste.
By Jim Fedako
This fall, school kids across the country will again be taught a chief doctrine in the civic religion: recycle, not only because you fear the police but also because you love the planet. They come home well prepared to be the enforcers of the creed against parents who might inadvertently drop a foil ball into the glass bin or overlook a plastic wrapper in the aluminum bin.
Oh, I used to believe in recycling, and I still believe in the other two R’s: reducing and reusing. However, recycling is a waste of time, money, and ever-scarce resources. What John Tierney wrote in the New York Times nearly 10 years ago is still true: “Recycling may be the most wasteful activity in modern America.”
Reducing and reusing make sense. With no investment in resources, I can place the plastic grocery bag in the bathroom garbage can and save a penny or so for some more-pressing need. Reducing and reusing are free market activities that are profitable investments of time and labor.
Any astute entrepreneur will see the benefit of conserving factors of production. Today, builders construct houses using less wood than similar houses built just 20 years ago. In addition, these houses are built sturdier; for the most part anyway.
The Green’s love for trees did not reduce the amount of wood used in construction; the reduction was simply a reaction to the increasing cost for wood products. Using less wood makes financial sense, and any entrepreneur worth his profit will change his recipe to conserve wood through better design or by substituting less dear materials for wood products.
Global resource depletion
by Ugo Bardi
André Diederen’s recent book on resource depletion
I have been thinking, sometimes, that I could reserve a shelf of my library for those books which have that elusive quality that I could call “modern wisdom”. Books that go beyond the buzz of the media news, the shallowness of politicians’ speech, the hyper-specialization of technical texts. That shelf would contain, first of all, “The Limits to Growth” by Meadows and others; then the books by Jared Diamond, James Lovelock, Konrad Lorenz, Richard Dawkins, Peter Ward and several others that have affected the way I see the world.
I think I’ll never set up such a shelf, I have too many books and too few shelves; many are packed full with three rows of books. But, if I ever were to put these books together, I think that the recent book by André Diederen “Global Resource Depletion” would make a nice addition to the lot.
The subject of resource depletion, of course, is well known to readers of “The Oil Drum”. So well known that it is difficult to think of a book that says something new. Diederen, indeed, succeeds in the task not so much in reason of the details on the availability of mineral commodities that he provides, but for the innovative way he describes our relation to the subject. In other words, Diederen’s book is not a boring list of data; it is a lively discussion on how to deal with the implications of these data. It is a book on the future and how we can prepare for it.
To give you some idea of the flavor of the book, just a quote:
(p. 43) “… it isn’t enough to have large absolute quantities (“the Earth’s crust is so big”) and to have all the technology in place. (p. 33) … we have plenty of water in the Mediterranean or Atlantic Ocean and we have ample proven technologies to desalinate and pipe the water to the desert, so, why isn’t the Sahara desert green yet?”
This is, of course, the crucial point of resource depletion: what counts is cost, not amounts (I plan to use this example in my next talk!). Diederen is an unconventional thinker and he goes deeply into matters that, in some circles would be thought to be unspeakable; for instance (p. 41)
Price? Really. More next week.

I believe these are custom made windows so they are not cheap either. ( on further review – I was wrong about that ) You can take that however you like.
Stimulus Package Offers Up to $1,500
Our windows and doors aren’t just beautiful – they can help you save energy. Virtually all Marvin products already meet or exceed federal ENERGY STAR guidelines. Now, you may qualify for a federal tax credit of up to $1,500 under the new stimulus program when you install energy-efficient Marvin windows and doors. At Marvin, we’re committed to providing you with durable, high-performance products that bring lasting value to your home. Your Marvin dealer will help you choose the windows and doors that give you the personalized look you desire – and the energy efficiency you need. Whether you’re building new or looking at remodeling or replacement, there’s never been a better time to purchase distinctive, energy-efficient windows and doors that are Built around you®.
Energy Efficiency Made Easy
Always striving to meet the needs of an ever-changing environment, Marvin builds energy effiency into product performance while bringing your inspiration to life. Marvin offers a variety of energy efficient glass options:
Low E II – Low E II features a double metallic coating on the inside glass surface to reflect or absorb the sun’s warmth and reduce damaging UV rays. Offers enhanced U-factor and Solar Heat Gain Coefficient.
LoE?-366? Glass – Featuring three metallic layers of silver, this glass rejects solar heat and features a lower Solar Heat Gain Coefficient than Low E II. Recommended for warm climates where cooling costs are high and also for areas where intense exposure to the sun is an issue.
High-R Tripane – Features two layers of Low E glass with a clear center pane for a lower U-factor.
Marvin also offers these enhancements to further increase the energy efficiency of your windows:
Energy Panel – Often confused with storm windows, an Energy Panel is a glazing option consisting of a removable, exterior glass panel finished on the edges by a surround. Energy panels cover the exposed glass surface of each sash, and offer added energy efficiency for wood windows with single glazing.
Storm and Screen Combos – A combination unit is composed of two movable glass panels and one movable screen panel. The individual panels can be configured multiple ways, and can be easily removed from the interior for cleaning.
Things To Know About Energy Efficiency
Understanding these common terms will help you select the right windows and doors.
U-factor – This measures the rate of heat loss and how well a product insulates. The lower the number, the better a product is at keeping heat inside a building. The U-factor is key in the winter months, and important to consider in choosing a window.
Solar Heat Gain Coefficient (SHGC) – This measures how well a product blocks heat from the sun. The lower the number, the better. In southern climates or high sun intensity areas, you might actually want to keep the sun’s heat out of your house. Windows can help do that.
R-value – This measures resistance to heat loss. Many people are familiar with the R-value because of its use in home insulation. But actually, for windows and doors, U-factor and solar heat gain coefficient are more important measurements.
Design Pressure Rating – The “DP” measures the amount of pressure a door or window will withstand when closed and locked. Each DP rating also establishes other performance factors such as water penetration; air infiltration; structural pressure; forced entry; and operational force. The higher the DP numbers, the better the performance. Look for the certified hallmark of the Window and Door Manufacturers Association.

One of the best purveyors of geothermal in the country and it is right next door in Fort Wayne.
Choosing a Residential WaterFurnace Comfort System Is Simply Smarter
WaterFurnace manufactures and sells more geothermal systems for homes than anyone else in the business. Why? Because we offer a wide variety of residential geothermal products. Our dealers and installers are the most highly trained in the industry. And we are wholeheartedly committed to customer support. All that makes us the first—and smartest—choice for a residential WaterFurnace system: the system that’s “Smarter from the Ground Up.”
Geothermal vs. Ground Water vs. Water Furnace
Geothermal energy has been used to heat and air condition buildings for several decades, and, during that time, these geothermal systems have been called many different things. Some of the more popular variations include geo-thermal, geoexchange, ground-water, ground-water assisted, ground-water-source, water-to-water, and even our company name, water furnace heating and cooling.
All of these terms, though, convey the same thought: use of geothermal heat pump technology to tap the energy in the earth’s surface and drive a heating and air conditioning system for both residential and commercial uses. The result is a green or natural heat pump that saves energy and benefits the environment.
