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 for 80 percent less power. He bough

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 annual carbon emissions by more than

6、 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 for efficiency is its costor, mo

7、re 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 Union unveiled a plan to cut energy us

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 Zone Water boilers, space heaters and air conditioners have been notoriously inefficient. The heat pump has altered that equation. I

14、t 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 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 1 million heat pumps have been installed in the past two years to heat water for showers and hot Factories From steel mills to paper factories, industry eats up about a
