A great snapshot of why it’s important that we curb our energy use – starting at home – by Lawrence Berkeley Lab:

$241 billion. That’s how much consumers spend each year on energy for home use. About 1 in 5 of the nation’s energy dollars is spent in homes. Energy efficiency improvements could cut this number by well over half.

90% of your time. That’s the proportion of the average American’s time spent indoors. The quality of indoor air is often worse than the air outside. Moisture and gasses from building materials are some of the many invisible sources of indoor air pollution. When done right, energy efficiency upgrades will also improve indoor air quality and make your home safer and more comfortable.

1.2 billion tons of greenhouse-gas emissions. That’s what is emitted (as carbon dioxide) into the atmosphere as a byproduct of making the energy to power U.S. homes. Every single thing done to save energy at home trims these emissions.

Did you know that the typical U.S. family spends about $1,900 a year on home utility bills? Unfortunately, a large portion of that energy is wasted. And each year, electricity generated by fossil fuels for a single home puts more carbon dioxide into the air than two average cars.

Right in your own home, you have the power to reduce energy demand, and when you reduce demand, you cut the amount of resources, like coal and gas, needed to make energy—that means you create less greenhouse gas emissions, which keeps air cleaner for all of us…and saves on your utility bills! Plus, reducing energy use increases our energy security.

How to clean up a broken CFL

CFLs contain a small amount of mercury sealed within the glass tubing. Here are some detailed instructions from the Environmental Protection Agency on how to safely clean up and dispose of a broken CFL bulb:

Before Cleanup: Air Out the Room

  • Have people and pets leave the room, and don’t let anyone walk through the breakage area on their way out.
  • Open a window and leave the room for 15 minutes or more.
  • Shut off the central forced-air heating/air conditioning system, if you have one.

Cleanup Steps for Hard Surfaces

  • Carefully scoop up glass pieces and powder using stiff paper or cardboard and place them in a glass jar with metal lid (such as a canning jar) or in a sealed plastic bag.
  • Use sticky tape, such as duct tape, to pick up any remaining small glass fragments and powder.
  • Wipe the area clean with damp paper towels or disposable wet wipes. Place towels in the glass jar or plastic bag.
  • Do not use a vacuum or broom to clean up the broken bulb on hard surfaces.

Cleanup Steps for Carpeting or Rug

  • Carefully pick up glass fragments and place them in a glass jar with metal lid (such as a canning jar) or in a sealed plastic bag.
  • Use sticky tape, such as duct tape, to pick up any remaining small glass fragments and powder.
  • If vacuuming is needed after all visible materials are removed, vacuum the area where the bulb was broken.
  • Remove the vacuum bag (or empty and wipe the canister), and put the bag or vacuum debris in a sealed plastic bag.

Disposal of Cleanup Materials

  • Immediately place all clean-up materials outdoors in a trash container or protected area for the next normal trash pickup.
  • Wash your hands after disposing of the jars or plastic bags containing clean-up materials.
  • Check with your local or state government about disposal requirements in your specific area. Some states do not allow such trash disposal. Instead, they require that broken and unbroken mercury-containing bulbs be taken to a local recycling center.

Home Sick Home

It seems like Americans are more health-conscious than ever these days, but do you ever ask yourself how healthy your home is? The Sierra Club has put together a list of 9 home health hazards to be aware of. The high points are summarized below.

1. Radon
You can’t see it or smell it, but radon kills about 20,000 Americans each year. It’s the number two cause of all lung cancers, and the leading cause of lung cancer among non-smokers in the United States.

Retrofitting most homes to reduce radon levels isn’t complicated, but you’ll probably want to hire a state-certified radon mitigation contractor. A basic mitigation system consists of a pipe and a fan that pulls radon from below your house and vents it to the outside, typically through the roof. The cost of reducing radon in a home ranges from about $800 to $2,500, according to the EPA.

2. Volatile Organic Compounds
Volatile organic compounds, or VOCs, are one of the main sources of air pollution in our homes. VOCs are a huge class of carbon-based chemicals that share a common trait: they are volatile at room temperature, meaning they readily release gases into the air we breathe.

The list of health effects from VOC exposure is enough to scare the daylights out of anyone: nausea; cancer; memory loss; eye, nose, and throat irritation; kidney, liver, and central nervous system damage.

3. Problems with Plastics
Although VOCs are the primary indoor air pollution culprit in our homes, they’re not the only chemical that can compromise human health. Many of the “miracle” plastics developed by science and industry in the past half-century turned out to have hidden health burdens. While completely eliminating harmful plastic items from your home may be next to impossible, you can reduce your exposure.

4. Pesticides and Herbicides
Pesticides and herbicides are biocides: they’re designed to kill living organisms. Makers of these chemicals may claim the products are safe when used properly, but why take the chance? Banning pesticides from your home and garden is an especially good idea if you have young children–their developing bodies are particularly vulnerable to pollutants.

5. Mold
You’ve probably encountered the sensationalist media stories about house-eating toxic molds. The truth is, mold spores are floating everywhere, in the air inside and outside our homes. There’s no way to keep mold spores out of the air. The trick to controlling mold in your home is controlling moisture–mold thrives on moisture.

If mold is allowed to multiply unchecked in a building, it can eventually cause serious damage to the structure. It also has the potential to affect health. Not everyone is bothered by mold but for some people, exposure may trigger allergic reactions, asthma episodes, or other respiratory problems.

6. Other Biological Contaminants
Pet dander, pollen, and feces of dust mites and cockroaches can trigger allergic reactions, asthma episodes, and other respiratory problems. Good housekeeping, especially dusting and vacuuming regularly, will help keep these particles in check.

7. Energy-related Risks
Carbon monoxide and other combustion byproducts
Devices that burn fuel inside your home are potential sources of air pollution. Burning gas, heating oil, propane, wood and kerosene produces many potentially harmful fine particles and gases, including carbon monoxide (CO), formaldehyde, and nitrogen dioxide. The minute quantities emitted by a properly functioning, modern fuel-burning appliance don’t typically cause health problems. However, if an appliance malfunctions it can spew potentially harmful, or even fatal, levels of CO and other chemicals into your home.

Electromagnetic fields
Unlike fuel-burning devices, using electricity won’t create indoor air pollution (although electricity generation is a leading source of outdoor air pollution and CO2 emissions). Does that mean using electricity is healthy?

Despite the lack of evidence that low-frequency EMFs cause health problems, some people remain concerned and try to limit their exposure. Easy ways to reduce EMFs include choosing energy-efficient appliances and equipment (our site gives you lots of tips about this) and eliminating “phantom loads” by unplugging appliances and devices that draw energy even when they’re turned off–that includes anything with a transformer, a remote, a timer, or memory.

8. Banned Building Materials
Millions of homes harbor lead-based paint, asbestos, and toxic wood preservatives. All three have been banned from building products, but they continue to plague building owners and occupants.

9. Emerging Concerns
There’s lots of good news on the home health front. Lead-based paint and asbestos have been banned for three decades. Radon can be a problem in some homes, but it’s not too difficult to take care of. Mold problems can almost always be solved by drying up the source of moisture. More and more people are becoming aware of potential hazards associated with VOCs, vinyl, and pesticides and are choosing alternatives that are safer for their families.

But it’s not as if our homes will soon be completely safe. New products and technologies are being introduced all the time, outpacing the efforts of risk assessment scientists, regulators, and health advocacy organizations to keep up.

Most people aren’t aware of exactly how their home’s air quality affects their health and the health of their family. Did you know that up to 30% of the air you breathe comes from your crawlspace? As you can imagine, crawlspace air is full of moisture and dirt, which can lead to issues such as respiratory distress and mold.

Here’s another example of the link between childhood asthma and formaldehyde exposure from household items such as furniture and carpet. Roughly 7% of adults and 9% of children suffer from asthma in the U.S. – by identifying the triggers, we can help improve the health of future generations starting at home.

What you need to know about indoor air pollution

The Environmental Protection Agency estimates that people spend 90% of their time indoors, but that indoor air quality can be two to five times more polluted than outdoor air. Indoor air pollution can threaten the health — and the lives — of everyone in your family.

The single most effective way to keep the air in your home healthy is to keep things out of your home that cause air pollution, including cigarette smoke and excess moisture and chemicals, and ventilate to pull dangerous pollutants out of the house.

The second most important strategy is to air seal your home. A leaky building envelope and ducts can pull in dirt, dust, particles, and mold.

Easy tips to improve Indoor Air Quality:
• Run bathroom and kitchen exhaust fans to ventilate moisture in the air
• Install a carbon monoxide detector
• Clean your A/C and dehumidifier
• If you have asbestos, hire a qualified company to properly remove it ASAP
• Install an air filtration system
• Avoid toxic products to cut down on VOCs
• Test your home for radon

Did you know? Up to 30% of the air in your home comes from your crawlspace.
