Minor oversights around a house can add up to major drains on your pocketbook, especially when it comes to the little things that make utility bills skyrocket.
"Air sealing is the key to significant reduction because we lose 31 percent of the air from our homes through floors, walls and ceilings," says Jamison Brown of AmeriSpec Home Inspection Services in Poquoson.
For instance, a crack as small as 1/16 of an inch around a window frame can let in as much cold air as leaving the window open three inches, according to Virginia Natural Gas.
The solution: Caulk and weather strip around exterior doors and windows to help eliminate cold-air sources. New this year is temporary caulking you easily peel off in spring.
Older homes can allow air from the crawl space to enter the living space if the gap between the floor and the bottom of the walls has not been sealed, something that's typically done in new home construction, according to Robert Criner of Criner Remodeling in York County. If you have light-colored carpet that's tinged darker around the outer edges, you know you have that kind of leak.
The solution: When you replace the carpet, run a bead of caulking along that gap before installing new carpet; if the carpeting is still good, pull up the trim and carpet edge, run the caulking, put the carpet back and replace the trim board.
Even electrical outlets allow cold air to enter your warm rooms. The next time the wind blows or cold air rolls into town put your hand over an electrical outlet on an exterior wall and you may be surprised at what you feel.
The solution: There are precut insulation pads you can buy at hardware and home stores to put in those outlets.
What's under or over your living space also impacts your energy bill, items like ductwork. Supply ductwork from your furnace can leak heated air into the attic or crawl space, and outside air can be drawn into the return ductwork, increasing costs and reducing your comfort, according to Dominion (NYSE:D) Power.
The solution: Inspect ductwork to make sure it's sealed at joints and intersections with foil-backed tape or silicone caulking. You also want to make sure ductwork is not kinked.
Many people, especially empty-nesters, also live in large houses where some rooms are not used. Why heat rooms you don't use?
The solution: During winter, close the registers in the room and use a foam "twin draft guard" under the door, like the $9.95 versions you see advertised on TV or in home stores. "They are cheap and they work," says Criner.
Rebates and assistance
To help households improve their energy efficiency, Virginia Natural Gas offers free programmable thermostats and a $50 rebate on a seasonal service to keep heating equipment running at peak performance. You can also get rebates of $150 on a high-efficiency tank water heater, $500 on a tankless water heater and $500 on a 90 percent or higher efficiency furnace.
Tax credits for energy-efficiency items like windows, roofs and insulation expire at the end of this year and must be installed by then, according to Criner.
Financially struggling households can apply for Energy Assistance programs through social services departments in cities and counties or online at http://www.dss.virginia.gov/benefit/ea/index.cgi
Save even more
Here are more winterizing and household energy-use tips from Jamison Brown and Michael Hatchett of Hatchett Design, Remodel and Repair in Newport News:
-- Caulk all exterior joints and gaps, including around dryer vents and joints in siding
-- Make sure door weather stripping seals when the door is closed.
-- Set your water heater to 120 Fahrenheit and install a water heater insulation blanket; read the label on the water heater to see if a blanket is suitable.
-- Install at least 6 feet of insulation on both the hot and cold water pipes attached to the water heater; caution should be used for gas water heaters with hot vent pipes.
-- Seal ceiling openings in the attic around electrical wires, plumbing pipes and bathroom or kitchen exhaust fan and associated piping.
-- Pull-down stairs need to be sealed or a tent placed over them in the attic to prevent air leakage and energy loss. You can build or buy one. Also, attic access scuttles and doors need to be sealed and insulated.
-- Bathroom vents and dryer exhausts and fireplaces should have a damper to ensure warm air is not unintentionally leaking from the home when those appliances are not being used. Most new bathroom vents have a damper unit already installed in the fan.
-- Review attic insulation and install additional insulating to bring it to R-38 factor after you have sealed any air leaks and insulated any pipes in that area.
-- Build air-tight covers for all recessed ceiling lights that are visible in the attic to prevent air leaks; use caution to ensure a fire hazard is not created by the light boxes; http://www.ehow.com features a piece on insulating these fixtures.
-- Finally, set back the thermostat, or turn down the heat while you are away at work. It takes less energy to warm a cool home than to maintain a warm temperature all day long.

Great Pacific Ocean Garbage Patch
update to the Great Pacific Ocean Garbage Patch
A HUGE CROWD FUNDED MACHINE IS ABOUT TO START CLEANING UP THE GREAT PACIFIC GARBAGE PATCH
What is the Great Pacific Ocean Garbage Patch?
Not all garbage ends up at the dump. A river, sewer or beach can't catch everything the rain washes away, either. In fact, Earth's largest landfill isn't on land at all.
The Great Pacific Garbage Patch stretches for hundreds of miles across the North Pacific Ocean, forming a nebulous, floating junk yard on the high seas. It's the poster child for a worldwide problem: plastic that begins in human hands yet ends up in the ocean, often inside animals' stomachs or around their necks. This marine debris has sloshed into the public spotlight recently, thanks to growing media coverage as well as scientists and explorers who are increasingly visiting the North Pacific to see plastic pollution in action.
What's it made of?
The Great Pacific Garbage Patch has sometimes been described as a "trash island," but that's a misconception, says Holly Bamford, director of NOAA's Marine Debris Program. If only things were that simple.
"We could just go out there and scoop up an island," Bamford says. "If it was one big mass, it would make our jobs a whole lot easier."
Instead, it's like a galaxy of garbage, populated by billions of smaller trash islands that may be hidden underwater or spread out over many miles. That can make it maddeningly difficult to study — Bamford says we still don't know how big the garbage patch is, despite the oft-cited claim that it's as big as Texas.
"You see these quotes that it's the size of Texas, then it's the size of France, and I even heard one description of it as a continent," she says. "That alone should lend some concern that there's not consistency in our idea of its size. It's these hot spots, not one big mass. Maybe if you added them all up it's the size of Texas, but we still don't know. It could be bigger than Texas."
While there's still much we don't understand about the garbage patch, we do know that most of it's made of plastic. And that's where the problems begin.
Unlike most other trash, plastic isn't biodegradable — i.e., the microbes that break down other substances don't recognize plastic as food, leaving it to float there forever. Sunlight does eventually "photodegrade" the bonds in plastic polymers, reducing it to smaller and smaller pieces, but that just makes matters worse. The plastic still never goes away; it just becomes microscopic and may be eaten by tiny marine organisms, entering the food chain.
About 80 percent of debris in the Great Pacific Garbage Patch comes from land, much of which is plastic bags, bottles and various other consumer products. Free-floating fishing nets make up another 10 percent of all marine litter, or about 705,000 tons, according to U.N. estimates. The rest comes largely from recreational boaters, offshore oil rigs and large cargo ships, which drop about 10,000 steel containers into the sea each year full of things like hockey pads, computer monitors, resin pellets and LEGO octopuses. But despite such diversity — and plenty of metal, glass and rubber in the garbage patch — the majority of material is still plastic, since most everything else sinks or biodegrades before it gets there.
How is it formed?
Earth has five or six major oceanic gyres — huge spirals of seawater formed by colliding currents — but one of the largest is the North Pacific Subtropical Gyre, filling most of the space between Japan and California. The upper part of this gyre, a few hundred miles north of Hawaii, is where warm water from the South Pacific crashes into cooler water from the north. Known as the North Pacific Subtropical Convergence Zone, this is also where the trash collects.
Bamford refers to the convergence zone as a "trash superhighway" because it ferries plastic rubbish along an elongated, east-west corridor that links two spinning eddies known as the Eastern Garbage Patch and the Western Garbage Patch. The whole system collectively makes up the Great Pacific Garbage Patch.
It may take several years for debris to reach this area, depending where it's coming from. Plastic can be washed from the interiors of continents to the sea via sewers, streams and rivers, or it might simply wash away from the coast. Either way, it can be a six- or seven-year journey before it's spinning around in the garbage patch. On the other hand, fishing nets and steel containers are often dropped right in with the rest of the trash.
What's the problem?
Marine debris threatens environmental health in several ways. Here are the main ones:
• Entanglement: The growing number of abandoned plastic fishing nets is one of the greatest dangers from marine debris, Bamford says. The nets entangle seals, sea turtles and other animals in a phenomenon known as "ghost fishing," often drowning them. With more fishermen from developing countries now using plastic for its low cost and high durability, many abandoned nets can continue fishing on their own for months or years. One of the most controversial types are bottom-set gill nets, which are buoyed by floats and anchored to the sea floor, sometimes stretching for thousands of feet.Virtually any marine life can be endangered by plastic, but sea turtles seem especially susceptible. In addition to being entangled by fishing nets, they often swallow plastic bags, mistaking them for jellyfish, their main prey. They can also get caught up in a variety of other objects, such as this snapping turtle that grew up constricted by a plastic ring around its body.
• Small surface debris: Plastic resin pellets are another common piece of marine debris; the tiny, industrial-use granules are shipped in bulk around the world, melted down at manufacturing sites and remolded into commercial plastics. Being so small and plentiful, they can easily get lost along the way, washing through the watershed with other plastics and into the sea. They tend to float there and eventually photodegrade, but that takes many years. In the meantime, they wreak havoc with sea birds such as the short-tailed albatross.
Albatross parents leave their chicks on land in Pacific islands to go scour the ocean surface for food, namely protein-rich fish eggs. These are small dots bobbing just below the surface, and look unfortunately similar to resin pellets. Well-meaning albatrosses scoop up these pellets — along with other floating trash such as cigarette lighters — and return to feed the indigestible plastic to their chicks, which eventually die of starvation or ruptured organs. Decaying albatross chicks are frequently found with stomachs full of plastic debris (see photo above).
• Photodegradation: As sunlight breaks down floating debris, the surface water thickens with suspended plastic bits. This is bad for a couple of reasons. First, Bamford says, is plastic's "inherent toxicity": It often contains colorants and chemicals like bisphenol-A, which studies have linked to various environmental and health problems, and these toxins may leach out into the seawater. Plastic has also been shown to absorb pre-existing organic pollutants like PCBs from the surrounding seawater, which can enter the food chain — along with BPA and other inherent toxins — if the plastic bits are accidentally ingested by marine life.
What can we do?
The discoverer of the Great Pacific Garbage Patch, Capt. Charles Moore, once said a cleanup effort "would bankrupt any country and kill wildlife in the nets as it went."
"He makes a really good point there," Bamford says. "It's very difficult."
Still, NOAA conducts flyovers to study the garbage patch, and two research teams sailed there last summer to collect debris and water samples. Scientists from the Scripps Institution of Oceanography held a press conference after returning from their three-week voyage in August, describing the amount of trash as "shocking." They found large and small items as well as a vast underwater haze of photodegraded plastic flakes, and are now analyzing their samples to figure out how the plastic interacts with its marine environment.
Meanwhile, the international Project Kaisei team also spent last August in the garbage patch, studying its contents in hopes of eventually recycling them or turning them into fuel. And "adventure ecologist" David de Rothschild is pushing on with plans to sail around the garbage patch in a boat made entirely of recycled plastics, taking a test voyage earlier this month after a long delay due to construction trouble. Called "Plastiki," the ship is intended to highlight the connection between plastic trash on land and plastic trash at sea — an increasingly evident link, thanks not only to media attention for the Pacific patch, but also the recent discovery of a similar patch in the North Atlantic.
Ultimately, more plastic recycling and wider use of biodegradable materials is the best hope for controlling these garbage patches, Bamford says, but that's an uphill battle.
"We need to turn off the taps at the source. We need to educate people on the proper disposal of things that do not break up, like plastics," she says. "Opportunities for recycling have to increase, but, you know, some people buy three bottles of water a day. As a society, we have to get better at reusing what we buy."

Using science, not garlic, to fight energy vampires

Scientists collaborating on the project will apply their expertise and research to tunnel field effect transistors and semiconducting nanowires to improve the efficient use of energy in electronics.
To explain the challenge, consider a leaky water faucet — even after closing the valve as far as possible water continues to drip — this is similar to today’s transistor, in that energy is constantly "leaking" or being lost or wasted in the off-state.
In Steeper, scientists not only hope to contain the leak by using a new method to close the valve or gate of the transistor more tightly, but also open and close the gate for maximum current flow with less turns, i.e. less voltage for maximum efficiency.
According to the International Energy Agency, electronic devices currently account for 15 percent of household electricity consumption, and energy consumed by information and communications technologies as well as consumer electronics will double by 2022 and triple by 2030 to 1,700 TWh — this is equal to entire total residential electricity consumption of the in U.S. and Japan in 2009.
Particularly wasteful is the enormous amount of standby consumption. In the European Union it is estimated that standby power already accounts for about 10 percent of the electricity use in homes and offices of the member States.
By 2020 it is expected that electricity consumption in standby/off-mode will rise to 49 TWh per year — nearly equivalent to the annual electricity consumption for Austria, Czech Republic and Portugal combined.
“Our vision is to share this research to enable manufacturers to build the Holy Grail in electronics, a computer that utilizes negligible energy when it’s in sleep mode, which we call the zero-watt PC,” said Prof. Adrian M. Ionescu, Nanolab, Ecole Polytechnique Federale de Lausanne, who is coordinating the project.
