These d
4、ays conservation is all about efficiency: getting the same - or better - results from just a fraction of the energy. When a slump in business travel forced Ulrich Romer to cut costs at his family-owned hotel in Germany, he replaced hundreds of the hotels wasteful light bulbs, getting the same light
5、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 lower energy needs have reduced its an
6、nual 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 global warming. But the best argument
7、 for efficiency is its cost - or, 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 agenda. On Jan. 10, the European Uni
8、on 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 speech this week.The good news
9、 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 prototype “zero-energy homes“ in Switze
10、rland 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 equipment, lowering costs even befor
11、e 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 electricity, or the equivalent of roug
12、hly 600,000 tons of coal a day. Forty percent of that powers old-fashioned incandescent light bulbs - a 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 leas electricity than incandescent bulbs to gen
13、erate 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 conditioners have been notori
14、ously 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 buildings in Sweden are already
15、heated with ground-source heat pumps. Such systems consume almost no conventional fuel at all. Several countries have used subsidies to jumpstart the market, including Japan, where almost 1 million heat pumps have been installed in the past two years to heat water for showers and hot tubs.Remake Fac
16、toriesFrom 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 chemical process is used to
17、power the next. At the Ludwigshafen 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 advantage,“ says BASF CEO Jurgen
18、 Hambrecht.Green DrivingA quarter of the worlds energy - including two thirds of the annual production of oil - is 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). Gasoline-electric hybrid
19、(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 manufacturers have already
20、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 residential power consumption
21、(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 Energy Technology Co. spe
22、cializes 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 saving energy is so easy and
23、 profitable, why isnt everyone doing it? It has to do with psychology and a lack of information. Most of us tend to look at todays price tag more than tomorrows potential savings. That holds double for the landlord or developer, who wont actually see a penny of the savings his investment in better i
24、nsulation 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 success that it extend
25、ed 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 increase in insulation l
26、evels 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 forced more compani
27、es 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 for the buck.2 What
