Working “Greener” Can Save Your Law Library Some “Green” Kathleen M. Sasala, Esq. Director, Cleveland Law Library ORALL, 2009 WAYS TO SAVE Examples of ways to save: 1. Curtailing business trips in favor of telephone or video conferences. 2. Changing the thermostat at the office 3. Using less paper and/or reusing paper 4. Saving energy on equipment and appliances. Have You Hugged a Tree Today? Ways We Have Saved Paper a) b) c) d) e) reducing the number of patron logs we use every day from 3 to 2; consolidating our public employees’ sign in sheets from 5 per week to 1 per week; scanning email documents directly into our copy machine without copying them first; sending board meeting documents and correspondence by email converting all but about 115 of our 2,300 members to receiving our newsletters by email. How These Efforts Saved Item Patron Logs Employee Sign-in Sheets New Scanning Digital Board Documents Electronic Newsletters Pages Saved 250 1,000 350 600 8,740 10,940 This equals 22 reams of paper (over 2 boxes) or $72.00 Regular Copy Paper Costs Vendor Cost per Box Xpedx $37.90 Staples $35.99 OfficeMax $39.99 United Office Products $45.99 Recycled Paper Costs Vendor Cost per Box Xpedx $59.90 Staples $40.99 Office Max $44.99 United Office Products $51.99 ENERGY SAVINGS Power down/turn off equipment Put equipment into sleep or standby mode Unplug equipment when you can E.g., adding machine, pencil sharpener, coffee machine, electric stapler, postal meter, postal scale, fan, and folding machine, etc. Hard Number Crunching • Let’s do some number crunching Assumptions Re: Office Hrs. (52 work weeks) • % Of Time The Office Is Open (8 hrs. a day): Days: 9:00 a.m.-5:00 p.m. 2,080 Hours = 24 % • % Of Time The Office Is Closed (16 hrs. a day): Evenings and overnight: 4,160 Hours Weekends: 2,496 Hours 6,656 Hours = 76% Assumptions Re: Energy Costs • Ohio average electricity cost: * 8.27 cents per kWh *http://www.eia.doe.gov/neic/brochure/electricity/electricity.html What Is A Watt ? What is a kilowatt? Watt: a watt is a measure of the rate of electrical use at any moment in time. _________________________________________ EQUIVALENCY 1 kilowatt hr == using 1,000 watts for 1 hr. (Kilo means one thousand) *http://michaelbluejay.com/electricity/cost.html#kilowatt How Many Watts Do Devices Use? • 60 Watt Light Bulb (incandescent) • CFL Light bulb (60 watt eq.) 60 watts 18 watts (compact fluorescent light bulb) • • • • • 17” LCD Monitor: 17” CRT Monitor Desktop Computer & 17” CRT Desktop & monitor asleep Laptop computer 40 watts 90 watts 150-340 watts 1-20 watts 45 watts Devices That List Amps and Volts AMPS x Volts = Watts (avg. is 120 volts) How To Calculate Energy Loss? FORMULA for LOSS WATTS x Hours 1000 Example: Usage 60 watt bulb x 16 hrs. 1,000 X Cost Per kilowatt hr. X .0827 = TOTAL COST = $.079/day = $2.37/mnth. = $28.44/yr. 60 Watt Bulb Savings Per… • Turning off 1-60 watt bulb for 16 hours a day: Saves: = $ .079/day = $ 2.37/mnth. = $ 28.44/yr. LCDs vs. CRTs LCD CRT Liquid Crystal Display (LCD) monitors use 1/3 to 1/2 the electricity of Cathode Ray Tube (CRT) monitors* * http://www.wisegeek.com/which-monitor-type-is-better-lcd-or-crt.htm LCD vs. CRT Comparison Savings LCD [40 watts]-turning off 1 LCD monitor 16 hrs per day =$.05 per day =$1.50 per month =$18.00 per year CRT [90 watts]-turning off 1 CRT monitor 16 hrs per day =$.12 per day =$3.60 per month =$43.20 per year Energy Star Equipment Joint Effort of U.S. EPA & U.S. DOE http://www.energystar.gov/index.cfm?c=about.ab_index Energy Star FAQ’s Energy Star equipment is certified to: run cooler last longer reduce greenhouse gas emissions save electricity Our Energy Star Fax Machine Saved us $17.00 to date over the last 12 months Energy Star Computers Windows and Mac’s: Operating systems put monitors and computers into a low-power “sleep mode” after a period of inactivity. Internet Calculator • EnergyStar.gov has an online calculator to figure savings on your particular computers and laptops: • http://www.energystar.gov/ia/products/power_mgt/LowCarbonITSavings Calc_v26_with_5_0v2.xls Sleepy Computers May Still Lose Energy A computer in sleep mode can still lose up to 6 watts of energy every moment. Putting your computer to sleep every day at lunch time could save between $2.15 - $6.06 per year. Better Savings from Unplugging Even better than sleeping is unplugging! Vampire Energy Sucks !
