ENERGY EFFICIENCY
Save $147.84 with just one light bulb.
Use just one 23-watt CFL instead of a 100-watt incandescent and you can save $147.84 based on the 2008 rate of $.20/kwh with the light on 10,000 hours (little more than one year if on all day and night.) Calculate your own savings at www.thebulb.com/store/t-cflmath.aspx .

Save $200 a year with just one smart power strip
Put just one computer on a smart power strip and you may save $200 a year if the cost of electricity is $.20 per kwh. How many computers are left on in your office? In many offices computers are on 24 hours a day, seven days a week. Savings add up quickly. A $20 investment may be paid back in 5 weeks by saving electricity costs!
A mid-sized company could save more than $165,000 a year just by turning off its computers at night.

Calculating Payback on Smart Power Strips Although prices vary, the average smart power strip could add a premium of about $20 to the cost of a regular power strip with equivalent surge protection. If the strip controlled 50 watts worth of task lights and a monitor using 100 watts, and electricity cost an average of 10 cents per kilowatt-hour, the device would pay for itself after preventing about 1,333 hours of operating time—a matter of less than two months if equipment otherwise would be left on 24 hours a day. How did we get this number? By multiplying the power saved (in kilowatts) by the energy rate, then dividing the cost premium by that product: $20 ÷ (0.15 kW x $0.10/kWh) = 1,333 hours. To determine how long it would take to eliminate 1,333 hours of operating time, first determine how many hours a day a smart power strip might prevent that equipment from operating. For example, a typical workday might be 9.5 hours long, during which monitors are inactive for 5.5 hours. Assume that the equipment is turned off at night and that the occupancy sensor time delay adds a half hour per day of operating time before the equipment is turned off. Then the smart power strip would save about five hours per day of operating time and pay for itself in 267 working days, or just over one year. If equipment is otherwise left on nights and weekends, the savings would be 143 hours per week for a payback of less than 10 weeks. www.uppco.com/business/eba_3.aspx (Upper Peninsula Power Company) |
| Nearly half of all corporate computers in the United States don't get turned off at night, costing U.S.businesses $1.72 billion in annual energy costs and spewing 14.4 million tons of carbon dioxide into the atmosphere per year, according to a new report. Let's give those numbers some context: A midsize company with around 10,000 PCs wastes more than $165,000 per year in electricity costs for computers left on overnight, while contributing 1,381 tons of carbon dioxide to the atmosphere. Giving those same computers a breather every night would have roughly the same effect as taking 2.58 million cars off the road, which is more than the number of autos zipping around the entire state of Maryland . http://www.ase.org/content/article/detail/3867 (June 2007) |
Weatherize doors and windows
A ¼ inch crack around a door is the same as an open window.
| “It’s only a little crack” - Example A pair of exterior doors with no weather stripping can have an opening of ¼” where the doors meet. While this doesn’t look or sound like much, on a 6’ 8” high pair of doors, it adds up to the equivalent of a 20-square inch opening. A similar gap in just two average-size double-hung windows, where the sashes meet, would add up to the same 20 square inch hole! In a typical setting, this 20 square inch hole would allow over 40 cfm into or out of the building. This air infiltration could cost up to $54 per year in heating and cooling costs. [NOTE: This was in August 2004. Energy costs are much higher now.] www.p2pays.org/ref/34/33606.pdf |

POLLUTION PREVENTION
One company saves $80,000 per year

| Cranston Print Works, Inc., Webster, MA - Chemical Substitution Case Study Spurred by a desire to meet the goals of the Massachusetts Toxics Use Reduction Act, the managers of Cranston Print Works altered their wastewater pH adjustment process to eliminate the use of sulfuric acid. The company installed a jet aeration system with injected liquid carbon dioxide to replace the two 4,300-gallon sumps in which wastewater neutralization had previously taken place. This $115,000 project eliminated the annual use of 2.66 million pounds of sulfuric acid. Although financial profit was not the main goal of the project, the company saved about $80,000 per year in chemical purchase and maintenance costs. http://www.mass.gov/envir/ota/publications/case_studies_desc.htm#11 |
TRANSPORTATION
WebEx
- One business person saves 2,690 pounds of carbon dioxide by moving her sales presentation online. 1 person flying fromNew York to London = 2,690 lbs of carbon emissions.
- Two partners save 4,696 pounds of carbon dioxide by moving their new business pitch online. 2 people traveling fromChicago to San Francisco = 4,696 lbs of carbon emissions.
Subaru of America
Darryl Draper, the national manager of customer service training for Subaru of America, used to travel four days a week, nine months of the year, presenting educational programs at dealers nationwide. Today, Ms. Draper rarely travels and nearly all of her training is done online.
Previously, Ms. Draper estimated, in six months she would reach about 220 people at a cost of $300 a person. She said she now reaches 2,500 people every six months at a cost of 75 cents a person. (Source: July 22, 2008 NY Times )

Ride Sharing
By 1995,The Rideshare Company created Easy Street® a vanpool network service that currently operates in Connecticut ,New York , Massachusetts and Rhode Island .
Commuters pay a monthly fee and The Rideshare Company takes care of everything else. From van maintenance to insurance, gas and program administration costs. They can even provide emergency rides, on a limited basis, when you have to leave before the van. The Rideshare Company has grown into a commuting force by significantly reducing the number of cars on the road each year resulting in a cumulative total of:
361 million less miles traveled
10 million fewer vehicle trips
180 thousand fewer tons of emission released into the air
17 million gallons of gasoline conserved

Green Jobs
A recent study by the American Solar Energy Society (ASES) reports that renewable energy and energy efficiency industries have generated approximately 8.5 million green collar jobs in the United States that number could grow to as many as 40 million green collar jobs by 2030. Globally, as demand for renewable energy increases, the practical applications of providing these Employee benefits as a recruitment "tool" is obviously advantageous, especially in attracting talent from outside the renewable market.
