But the U.S. hasmore than 100 million existing homes, and it would be __47__ wasteful to tear them all downand __48__ them with greener versions. An enormous amount of energy and resources wentinto the construction of those houses. And it would take an average of 65 years for the__49__ carbon emissions from a new energy-efficient home to make up for the resources lostby destroying an old one. So in the broadest __50__, the greenest home is the one that hasalready been built. But at the same time, nearly half of U. S. carbon emissions come fromheating, cooling and __51__ our homes, offices and other buildings. "You can't deal with climatechange without dealing with existing buildings," says Richard Moe, the president of the NationalTrust.

　　With some __52__, the oldest homes tend to be the least energy-efficient. Houses builtbefore 1939 use about 50% more energy per square foot than those built after 2000, mainlydue to the tiny cracks and gaps that __53__ over time and let in more outside air.

　　Fortunately, there are a __54__ number of relatively simple changes that can green olderhomes, from __55__ ones like Lincoln's Cottage to your own postwar home. And efficiencyupgrades (升級(jí)) can save more than just the earth; they can help __56__ property ownersfrom rising power costs.
