Make your air conditioning dollars go farther

When temperatures rise outside, it's natural to seek cool shelter indoors. For many people, that means flipping on the air conditioning unit and taking it easy. Keeping the air cool is more than a luxury for some families; elderly parents and young children cannot tolerate excessively high temperatures. However, the need for air conditioning puts many families at financial risk. A pricey combination of rising fuel costs and high electrical demand make summertime electric bills hard to manage.

According to Energy Star, the American family pays nearly $1,000 a year on heating and cooling their homes; that figure is above other electrical costs! You don't have to risk exposing your loved ones to brutal heat to save money.

Take advantage of some money-saving tips and beat the summer heat.

Help circulate cool air through the home by placing an oscillating fan in family rooms, like a living room or dining room.

Keep the temperature at constant temperature and avoid dropping the thermostat too low. Lowering the temperature costs you money and won't cool the home any faster.

Raise the thermostat 2 to 3 degrees before you leave for work if no one will be home. The energy experts at APS say that moving the temperature up 5 degrees for eight hours a day can save you $3 to $5 a month.

Install a whole house fan system. Whole house fans pull the hot attic air out of the home and keeps the air circulating, giving your home a cooling effect. This move could chill your home by a few degrees.

Replace old air conditioning units. If your window unit is a decade old, it needs to be replaced with an energy efficient unit. If your home has central AC, have the thermostat calibrated and the system charged yearly.

APS says homeowners should replace their older SEER units (Seasonal Energy Efficiency Ratio) to save energy bucks. Replacing a unit with a SEER rating of 10 with one that has an 18 SEER rating you could save up to 50% on your AC costs annually.

 Change the air conditioning filters regularly; once a month is suitable. Good air flow across the filter will cut down on cooling costs and stop allergens from floating around your home. FPL Energy Services say that air filters cost between $10 and $25 a piece, but replacing them can save you 5 to 15 percent on your monthly bill.

Hang insulated curtains in your windows. Sheer curtains look nice, but they don't provide any barrier between you and the outdoor heat. Keep windows covered during hot afternoons.

Also, do a walk through of your home while the air is on. Check for leaks around windows and doors. Sometimes your energy dollars simply float out the window!

Homeless Shelters Get Solar Power

The newly constructed Loudoun County Homeless Services Center in Leesburg, Virginia, destined to become a Silver-certified LEED building, recently began generating part of its electricity needs for the facility with a 9.5-kilowatt solar photovoltaic array, which in Virginia's relatively sunny climate can be expected to deliver about 13,000 kilowatt-hours per year, or enough to power a large American home.

LEED (Leadership in Energy and Environmental Design) is the international paradigm for building efficiency and environmental awareness, and certifications are awarded in three categories: Silver, Gold and Platinum. Administered as third-party certification by the U.S. Green Building Council, or USGBC, the designations recognize cutting-edge implementation of technology in five specific areas: energy savings, water conservation, carbon dioxide emissions reduction, enhanced indoor environmental quality, and conservation of resources with an eye to a system's impacts.

The Loudon system, installed by Gaithersburg, Maryland-based Standard Solar, will also prevent about 9.3 metric tons of carbon dioxide per year from being generated by Dominion Virginia Power, which generates more than 40 percent of electricity from coal. The carbon dioxide prevented by Loudon's solar system is also the equivalent of taking about 2 compact cars off the road, or planting 239 trees.

Standard Solar is a design-build solar firm operating in the public and private sector serving more than 400 solar-system owners in the Mid-Atlantic Region, and has created more than 50 'green' jobs since the summer of 2008, in spite of the recession.

The Loudon County Homeless Services Center, opened in September of 2009, was designed by Architecture, Inc., of Reston, Virginia, a LEED-certified design company, and offers transitional housing, a 24-bed short-term facility, and Emergency Cold Weather and Daytime Drop-in Centers for persons at risk. The center also features passive solar lighting and energy-efficient appliances.

The Loudon solar system is comprised of 44 panels at 216 watts each, manufactured by Memphis, Tennessee-based Sharp USA and funded via the Federal Community Development Block Grant through the American Recovery and Reinvestment Act (ARRA, 2009), which mandates that equipment be made in America.

Passive smoking

("Second hand smoke")

Passive smoking is the inhalation of smoke, called secondhand smoke (SHS) or environmental tobacco smoke (ETS), from tobacco products used by others. It occurs when tobacco smoke permeates any environment, causing its inhalation by people within that environment. Scientific evidence shows that exposure to secondhand tobacco smoke causes disease, disability, and death.



Passive smoking has played a central role in the debate over the harms and regulation of tobacco products. Since the early 1970s, the tobacco industry has been concerned about passive smoking as a serious threat to its business interests; harm to "innocent bystanders" was perceived as a motivator for stricter regulation of tobacco products. Despite an early awareness of the likely harms of secondhand smoke, the tobacco industry coordinated to engineer a scientific controversy with the aim of forestalling regulation of their products.



Currently, the health risks of secondhand smoke are a matter of scientific consensus, and these risks have been one of the major motivations for smoking bans in workplaces and indoor public places, including restaurants, bars and night clubs.


The term thirdhand smoke was recently coined to identify the residual tobacco smoke contamination that remains after the cigarette is extinguished and secondhand smoke has cleared from the air. Preliminary research suggests that byproducts of thirdhand smoke may pose a health risk, though the magnitude of risk, if any, remains unknown.


Long-term effects


General:
Overall increased risk; reviewing the evidence accumulated on a worldwide basis, the International Agency for Research on Cancer concluded in 2004 that "Involuntary smoking (exposure to secondhand or 'environmental' tobacco smoke) is carcinogenic to humans."

• Lung cancer
• Breast cancer
• Renal cell carcinoma (RCC)
• Pancreatic cancer
• Brain tumor
• Ear, nose, and throat: risk of ear infections
• Circulatory system: risk of heart disease, reduced heart rate variability, higher heart rate
