2、ights, and taking fewer showers. These days conservation is all about efficiency: getting the sameor betterresults from just a fraction of the energy. When a slump in business travel forced Ulrich Ramer to cut costs at his familyowned hotel in Germany, he replaced hundreds of the hotels wasteful lig
3、ht bulbs, getting the same light for 80 percent less power. He bought a new water boiler with a digitally controlled pump, and wrapped insulation around the pipes. Spending about 100,000 on these and other improvements, he slashed his 90,000 fuel and power bill by 60,000. As a bonus, the hotels lowe
4、r energy needs have reduced its annual carbon emissions by more than 200 metric tons. “For us, saving energy has been very, very profitable,” he says. “And most importantly, were not giving up a single comfort for our guests.”Efficiency is also a great way to lower carbon emissions and help slow glo
5、bal warming. But the best argument for efficiency is its costor, more precisely, its profitability. Thats because quickly growing energy demand requires immense investment in new supply, not to mention the drain of rising energy prices.No wonder efficiency has moved to the top of the political agend
6、a. On Jan. 10, the European Union unveiled a plan to cut energy use across the continent by 20 percent by 2020. Last March, China imposed a 20 percent increase in energy efficiency by 2020. Even George W. Bush, the Texas oilman, is expected to talk about energy conservation in his State of the Union
7、 speech this week.The good news is that the world is full of proven, cheap ways to save energy. Here are the seven that could have the biggest impact.InsulateSpace heating and cooling eats up 36 percent of all the worlds energy. Theres virtually no limit to how much of that can be saved, as prototyp
8、e “zero-energy homes” in Switzerland and Germany have shown. Theres been a surge in new ways of keeping heat in and cold out (or vice versa). The most advanced insulation follows the law of increasing returns: if you add enough you can scale down or even eliminate heating and air-conditioning equipm
9、ent, lowering costs even before you start saving on utility bills. Studies have shown that green workplaces (ones that dont constantly need to have the heat or air-conditioner running) have higher worker productivity and lower sick rates.Change BulbsLighting eats up 20 percent of the worlds electric
10、ity, or the equivalent of roughly 600,000 tons of coal a day. Forty percent of that powers old-fashioned incandescent light bulbsa 19th-century technology that wastes most of the power it consumes on unwanted heat.Compact fluorescent lamps, or CFLS, not only use 75 to 80 percent less electricity tha
11、n incandescent bulbs to generate the same amount of light, but they also last 10 times longer. Phasing old bulbs out by 2030 would save the output of 650 power plants and avoid the release of 700 million tons of carbon into the atmosphere each year.Comfort ZoneWater boilers, space heaters and air co
12、nditioners have been notoriously inefficient. The heat pump has altered that equation. It removes heat from the air outside or the ground below and uses it to supply heat to a building or its water supply. In the summer, the system can be reversed to cool buildings as well.Most new residential build
13、ings in Sweden are already heated with ground-source heat pumps. Such systems consume almost no conventional fuel at all. Several countries have used subsidies to jump-start the market, including Japan, where almost I million heat pumps have been installed in the past two years to heat water for sho
14、wers and hot tubs.Remake FactoriesFrom steel mills to paper factories, industry eats up about a third of the worlds energy. The opportunities to save are vast. In Ludwigshafen, German chemicals giant BASF runs an interconnected complex of more than 200 chemical factories, where heat produced by one
15、chemical process is used to power the next. At the Ludwigshafen site site alone, such recycling of heat and energy saves the company 200 million a year and almost half its CO2 emissions. Now BASF is doing the same for new plants in China. “Optimizing (优化) energy efficiency is a decisive competitive
16、advantage,” says BASF CEO Jurgen Hambrecht.Green DrivingA quarter of the worlds energy-including two thirds of the annual production of oilis used for transportation. Some savings come free of charge: you can boost fuel efficiency by 6 percent simply by keeping your cars tires properly inflated (充气)
17、. Gasoline-electric hybrid(混合型的) models like the Toyota Prius improve mileage by a further 20 percent over conventional models.A Better FridgeMore than half of all residential power goes into running household appliances, producing a fifth of the worlds carbon emissions. And thats true even though m
18、anufacturers have already hiked the efficiency of refrigerators and other white goods by as much as 70 percent since the 1980s. According to an International Energy Agency study, if consumers chose those models that would save them the most money over the life of the appliance, theyd cut global resi
19、dential power consumption (and their utility bills) by 43 percent.Flexible PaymentWho says you have to pay for all your conservation investments? “Energy service contractors” will pay for retrofitting（翻新改造）in return for a share of the clients annual utility-bill savings. In Beijing. Shenwu Thermal E
20、nergy Technology Co. specializes in retrofitting Chinas steel furnaces. Shenwu puts up the initial investment to install a heat exchanger that preheats the air going into the furnace, slashing the clients fuel costs. Shenwu pockets a cut of those savings, so both Shenwu and the client profit.If savi
21、ng energy is so easy and profitable, why isnt everyone doing it? It has do with psychology and a lack of information. Most of us tend to look at todays price tag more than tomorrows potential saving. That holds double for the landlord or developer, who wont actually see a penny of the savings his in
22、vestment in better insulation or a better heating system might generate. In many peoples minds, conservation is still associated with self-denial. Many environmentalists still push that view.Smart governments can help push the market in the right direction. The EUs 1994 law on labeling was such a su
23、ccess that it extended the same idea to entire buildings last year. To boost the market value of efficiency, all new buildings are required to have an “energy pass” detailing power and heating consumption. Countries like Japan and Germany have successively tightened building codes, requiring an incr
24、ease in insulation levels but leaving it up to builders to decide how to meet them.The most powerful incentives, of course, will come from the market itself. Over the past year, sky-high fuel prices have focused minds on efficiency like never before. Ever-increasing pressure to cut costs has finally
25、 forced more companies to do some math on their energy use.Will it be enough? With global demand and emissions rising so fast, we may not have any choice but to try. Efficient technology is here now, proven and cheap. Compared with all other options, its the biggest, easiest and most profitable bang
