Show DAILY UTAH CHRONICLE Wednesday, December 10, 2008 Green appliances not saving much Isabella Bravo STAFF WRITER Energy-efficient appliances save the U small bucks. James Parker, the U director of purchasing, explained that the U saves money when it buys an energy-efficient appliance over a conventional appliance. If green purchases have any extra initial costs, then the savings in electricity cancels out. TheEnvironmentalProtection Agency and the U.S. Department of Energy teamed up in 1992 to introduce an evaluation and label program to help customers buy energyefficient appliances. ENERGY STAR now partners with more than 12,000 companies and organizations and has become the industry standard for energy efficiency. "It's hard not to buy ESTAR," said Kathy Ingleby, the senior buyer who heads the U's green procurement program. She estimates that for each ESTAR-compliant computer, the U saves $48 annually and $176 during the unit's lifetime, which is approximately three to four years. Jeff Hymas, a spokesman for Rocky Mountain Power, said an onslaught of new customers in the Salt Lake Valley and increasing demand among existing customers puts upward pressure on electricity rates. Rocky Mountain Power currently provides the ioth-lowest rate in the country at 6.41 cents per kilowatt-hour. The U saved approximately $1,992 this semester by purchasing 83 ESTAR compliant computers from Dell and Hewlett-Packard and an estimated $3,984 over the course of the units' lifetimes. Both Dell and HP, the U's leading suppliers for each 178OE.

Dell updated its ESTAR requirements in 2007 and estimates that the new models save greenhouse gas emissions equal to taking one car off the road for three weeks. The U also leased and bought approximately 21 new ESTAR compliant copiers from Xerox and Ricoh. Ingleby said the copiers purchased through state contracts require the appliances to be ESTAR compliant. Ingleby estimated that if each copier lasts a little more than five years, the lifetime savings would total 1,186 kilowatt-hours, $no and 1,826 lbs. of carbon dioxide. Parker and Ingleby agreed that the total environmental cost and financial savings are difficult to calculate. For example, carbon dioxide savings should change over time, Hymas said. Rocky Mountain Power's current electricity comes from a number of fuel sources: 65 percent from coal, 9 percent from natural gas, 9.6 percent from hydroelectric, 3.6 percent from renewable sources and 12.8 8O1-582-65O6 SERVING STUDENTS OF THE UNIVERSITY OF UTAH OFFERING OVER 2OO FREE CLASSES STARTING FROM 6:3O A .

However, by 2016 the percentages will change and so will the emissions. The company plans to decrease coal to 43.4 percent, increase natural gas to 18 percent and increase renewable sources to 8.5 percent. Hymas said that based on demand projections, the current generation composite could not meet future demands. Hymas added that electricity rates might go up to cover the cost of additional new generation, but all price increases require a prior review and acceptance by the Utah Public Service Commission. An increase in energy rates would also increase the monetary savings collected by energyefficient appliances. Parker said he believes that whether the savings are small or large, saving the environment is a part of the U's responsibility. "It's not all about saving money", he said. "People who have the money to do it, should do it," i.bravo@ chronicle.utah.edu 1 8 SORORITIES 13 FRATERNITIES. 1 6 STUDENT COMMITTEES, WIRELESS INTERNET A N D MORE...

Using data from 33 non-Western countries, Cashdan showed you may need a crystal ball to see the that many women had a higher waist-to-hip ratio, which contradicts the idea that a lower ratio is the optimal body type and an evolutionary development. Mercedes Ward, a doctoral anthropology student who has worked with Cashdan on similar studies, said the idea about optimal shape has always revolved around reproductive ability and fitness, which a body type with a waist-hip ratio lower than 0.7 is more likely to encompass. "But when you look at the data, the average is not 0.7," Ward said. More women in non-Western populations, such as cultures in Africa or New Guinea, have body types above the expected ideal, which Cashdan believes is because they have added more testosterone and other hormones that help them survive better in their environment. The same hormones that are more prevalent in women with a higher waist-to-hip ratio contribute to quick responses to stressful situations. Higher levels of testerone-like hormones contribute to holding more fat in the stomach and give women attributes similar to that of men, "Women with high..levels (of those hormones) are more likely to describe themselves as action-oriented, resourceif you haven't tried the freshest new eatery in ful, controlling and powerful," town, what are you waiting for? something Cashdan said in the study. free? well, okay then, just spend $5 on any of In a hunter-gatherer sociour signature sandwiches, flatbread pizzas, ety, women were expected to provide food for their families. sushi, incredible salads or soups, and we'll Cashdan said even in Africa togive you a free Lavazza'^ coffee, oven-roasted day, women play an important sweet potato fries or Tanga™ tart frozen yogurt role in supporting their chilwith this ad. come discover a whole new dren, "In horticultural societies in healthy way to eat on the go at au naturale™. places such as Africa and New Guinea, women do most of the work, they do most of the cultivation," Cashdan said.
